ELEVEN YEARS AGO, I purchased land on the west coast 10 miles south-east of Dargaville. It is rolling country with sandy soils of two types, one of good quality, and known as Red Hill sand, and the other, Te Kopuru sand, a sandy gumland with a pan beneath. The climate is generally mild, but very strong westerly winds carrying sea spray are a feature of the area, and the effects of dry summers are felt very quickly. The farm comprises 131 acres, and was purchased in two blocks, one of 85 acres and one of 46 acres. In 1956, I went on to the farm with 44 heifers of my own, and 5 cows and 20 yearlings I had purchased. The only other things I owned were a truck, a tractor 20 years old, and a mower.

Manuka beetle (Pyronota spp Bois Coleoptera Scarabaeidae) has often been reported causing pasture damage frequently in areas close to bush margins Larvae feed on the roots of pasture species producing damage that is often attributed to grass grub (Costelytra zealandica) During 200607 significant pasture damage was observed in dairy pastures established on flipped developments on sandy soils near Cape Foulwind and on hump and hollow developments near Bell Hill north of Lake Brunner Sampling revealed damage was caused by high populations of manuka beetle larvae; no grass grubs were found in either region The common manuka beetle Pyronota festiva was identified from both areas and a second Pyronota species (P edwardsi or P setosa) was found only on the sandy soils at Cape Foulwind A pathogen survey of Pyronota larvae from both regions showed very low levels of infection by bacterial and protozoan pathogens but did reveal moderate infection by the fungi Metarhizium and Beauveria in 3rd instar larvae A laboratory bioassay at 15C showed late third instar Pyronota spp larvae were susceptible to infection by Metarhizium anisopliae and Beauveria bassiana spores mixed into soil Further work will evaluate a promising local Beauveria brongniartii isolate as a biocontrol option against this emerging pest

Twenty-five species of Polychaeta recently collected off the coast of British Columbia are discussed. Most were taken in waters of considerable depth off the west coast of Vancouver Island. Sixteen are new to British Columbia. Most of these are known from farther south on the west coast of North America, but some from much shallower depths than those from which they are now recorded; two of them are new to the northeast Pacific; one is a new subspecies. The other nine have been previously known from British Columbia, but they are now recorded from much greater depths than hitherto, or in new geographical locations.

The Villosa species group in the genus  Ehrharta Thunb. is differentiated morphologically by very large, profusely hairy, bearded and aristate spikelets and by a suffrutescent habit, with culms woody at the base and with reduced leaf blades. The Villosa group is composed of two species, one with a variety: E. thunbergii Gibbs Russell, nom. nov., E. villosa Schult. f. var.  villosa and E. villosa var. maxima Stapf. Members of the group occur on sandy soils in the Succulent Karoo and Fynbos Biomes, along the west coast in Strandveld and on the southern coast as far east as the Fish River. Morphologically, the group appears to be related to the Calycina and Capensis groups.

Faunal mass mortalities are a sporadic, but not uncommon, feature of the West and South coasts of South Africa. Five mass mortalities of West Coast rock lobsterJasus lalandii, including three of the most severe ever recorded in South Africa, occurred in the 1990s and resulted in the stranding of about 2263 tonnes of lobster. The bulk (97%) of the loss occurred in the last three years of the decade. The five events occurred within an 80 km stretch of coastline that straddled two fishing zones and resulted from hypoxic conditions associated with highbiomass dinoflagellate blooms. In each case, the quantity of lobsters stranded was directly related to the extent or duration of low-oxygen conditions. Small females constituted the bulk of the lobster stranded in most events. The lobster fisheries in the affected fishing zones suffered severe impacts. Recovery in one zone appears to be extremely slow, whereas the other zone is more resilient. Not only would a continuation of the trend of increasing frequency and severity of lobster strandings devastate the rock-lobster fishing industry and the employment prospects of small fishing communities, but it could also seriously affect the ecology of the region.

SYNOPSIS Forecasting the weather on the west coast of Africa is made difficult by the inaccurate pressure reports of ships at sea and of land stations whose elevation are not definitely known. However, from reliable reports of coastal stations a relation between pressure changes and wind variations is demonstrated, (see fig. 2–4). In each example a 24–48 hour pressure fall with onshore winds all along the coast was followed by a 24–48 hour pressure rise with off-shore winds. Two examples of pressure variations on a ship's barogram when a “tornado” occurred are given in fig. 5–6. Each diagram shows a falling pressure tendency followed by a rising tendency, with the “tornado” at the minimum pressure in the first case and 10 hours after the minimum in the second case. Evidently whenever these tendencies are observed together thunderstorms should be forecasted. This is born out for the statistics July to October 1934 which show 15 thunderstorms on the 22 days when the pressure was rapidly rising, and only 10 thunderstorms for the other 61 days!

My last general paper on Florida Coleoptera was prepared in the autumn of 1924, and appeared in the Canadian Entomologist for July, 1925. Since that was written my time has been largely devoted to the final preparation and publication of the “Heteroptera of Eastern North America.” During the three years which have elapsed I have spent the winters at Dunedin on the west coast of Florida, but have made three additional collecting trips, of three or four weeks each, to Royal Palm Park. One of these was in December, the other two in March and April. This park comprises an area of 4,000 acres lying in extreme southern Florida, about 40 miles northeast of Cape Sable.

The second known species in the genus Colletteichthys is described from the Arabian Peninsula and the northern ArabianSea, supporting the validity of the genus Colletteichthys. Compared to the other known species, C. dussumieri from India,C. occidentalis has only a single tentacle above the eye whereas C. dussumieri has two or more. Colletteichtyhs dussumieri is restricted to the west coast of India.

A low-pass filtered aeromagnetic map of southern Vancouver Island is inverted into a magnetization-contrast map that illustrates the lateral variations in the magnetization of the crust. The Island Intrusions and the West Coast Crystalline Complex are characterized by high magnetization relative to the other lithologic groups. The Island Intrusions form an almost continuous pluton in the deeper part of the crust. The low-magnetic Leech River Formation thickens northward. The almost uniform magnetic signature of the Leech River Formation in the east–west direction indicates that the crustal structure revealed from the Lithoprobe seismic results is typical throughout the formation west of the Survey Mountain fault. A low-magnetic zone, elongated in the northwest–southeast direction, cuts through the high-magnetic Metchosin basalts from the southern tip of the island to the Leech River fault. It coincides with the Sooke gabbros exposed in the southern tip of the island, implying that the gabbros probably cut the entire Metchosin basalts at depth.

The report of genus Emerita from Indonesia has only contained one species, namely Emerita emeritus. They were found on the west coast of Sumatera and the south coast of Java. Although Indonesia is the number two country in the world that has long beaches and is dominated by sandy beaches, as the preferred habitat for sand crabs, reports regarding these biotas in Indonesia are still limited. The previous studies have expected about the occurrence of the other species which was related to Emerita emeritus in Southern Java. We reported the new species of Emerita which was found in Pangandaran beach, West Java. We found it in an intertidal area, near Citonjong Estuary. Here, we described and illustrated the species.

A new species of squat lobster, Babamunida debrae, was found in shallow waters of the west coast of Hawai‘i. It is readily distinguished from all the other species of the genus by the presence of a pair of spines on the second abdominal tergite. Babamunida debrae is the second species of the genus from Hawaii and seventh species of the genus from the Indo-Pacific.
