The first instar and mature larva and pupa of Cassidispa relicta Medvedev, 1957, a newly recorded species from China, are described and figured. The chaetotaxy of the head, mouthparts, legs, and dorsal and ventral surfaces of the body is described. This is the first detailed description of immatures in the genus Cassidispa. Diagnostic characters of this species are compared with other described immatures of some Hispini genera. Biological notes on C. relicta, such as host plants, feeding patterns of adults, structure of larval mines and life history, are also presented.

Mature larva of Hydrothassa fairmairei (Brisout) is described and illustrated for the first time, based on specimens collected on Ranunculus spp. (Ranunculaceae) in Spain. A key to known larvae of genus Hydrothassa Thomson is provided. Diagnostic characters for the identification of species within this genus are number and size of abdominal dorsal tubercles, size of prothoracical setae and number of setae of anterior dorsal mesoand metathoracical tubercles. The larva of H. fairmairei is similar to that of H. marginella (Linné), but is clearly separated by the number of setae of dorsal anterior tubercle of mesoand metathorax. Notes on distribution and host plants are included.

Seeing in the last number of the Canadian Entomologist, a description of the egss of A. Luna, reminds me to ask of you the explanation of a curious circumstance in the life-history of one bred by me from the larva last year. I will premise that I am writing without my notes, and therefore cannot give figures accurately, but can give the facts. There may be nothing very strange about it, but two of the best entomologists in the United States inform me that it is entirely new to them. It is this:–Some time in the latter part of the summer of 1868 I took, feeding on walnut leaves, a mature larva of A. Luna; from which I did not houi to rear the mature insect, because I counted on the larva over twenty eggs like those of a Tachina, Underneath some of the eggs I could discern with a lens a minute opening through which the fly-larva had entered the body of the Luna larva. The skin of the latter was more or less discoloured under each egg, but under some-under many in fact there was a dense black spot, sometimes two lines in diameter.

The study of immature stages in Pentatomidae contributes to the knowledge in several areas, mainly systematics, ecology and agriculture. In faunistic inventories, nymphs comprise a significant part of the specimens collected, which often cannot be identified due to lack of knowledge about the immature. Here, we describe the external morphology of eggs and nymphal stages of Runibia perspicua (Fabricius, 1798). The egg is barrel-shaped with the surface of chorium covered by spines, forming polygonal markings interconnected by sheets, similar as observed in some species of Carpocorini. In all the nymphal instars the abdomen is characterized by having rounded reddish spots and an orange/yellow longitudinal macula in the middle of each abdominal tergite, from abdominal segment II to VII. The first instar is the most distinctive, standing out mainly by the head and thorax totally brown. From the second instar the head and thorax acquire pale color with irregular brown spots. The labium presents significant variations in size along the ontogenetic development showing a non-isometric pattern, when compared to the total length of the body. Illustrations and photographs of all the immature stages and the detailed morphology of some structures in SEM are provided.

Sap beetle, Epuraea ocularis Fairmaire usually lays eggs and breeds on fermenting overripe fruits, and larvae pass through different instars before pupating on soil. In laboratory condition, mating pairs of adults copulated and females laid eggs in clusters; larva hatched out in 1 to 2 days, passed through four instars; mature larva migrated to soil for pupation. Larval development took about 12 to 17 days; and adult hatched out of pupa in about 4 to 5 days. Detailed morphology of egg, larva and pupa is presented herein, and significance of larva in taxonomy of beetles has been indicated.

AbstractThe egg, larva, and pupa of Caurinus dectes are described and illustrated. Eggs are ellipsoidal, coated with black cement, and are attached to bryophytes. The larva is orthosomatic, with much-reduced thoracic legs, and further differs from other larval Boreidae in: amphipneustic spiracles, number of stemmata (7), placoid sensilla present in membrane of first antennal segment, and egg burster on frons in first instar. Three larval instars are recognized from analysis of head measurements and partial rearing. Larvae feed in stemmines or galleries in leafy liverworts (Jungermanniales). Pupation occurs in a silk-lined cell or cocoon, otherwise unknown in the Mecoptera; the pupa is exarate, with decticous mandibles. The seasonal occurrence of egg eclosion (February-March), pupation (July-August), and principal adult activity (October-April) is typical for the Boreidae, but only C. dectes is univoltine in this family. Successive annual generations appear to overlap through extended egg diapause and adult perenniation.

The morphology of larva and pupa, as well as larval mines of Elachista zonulae (Sruoga, 1992) are described and illustrated for the first time. Carex firma Host is reported as a new host plant ofthe species; previously only Carex sempervirens Vill. was known to be host plant of E. zonulae. Some information on life history of this elachistid moth is also provided. The mature larva is 4.5—5.5 mm long. Pupation takes place usually at base of leaf blade of the food plant. The species is univoltine and hibernates as young larva.

Taxonomic and biological notes are given for the East Asian sawfly Pristiphora ribisi Togashi, 1990, injurious to Ribes. The following new synonyms of this species are proposed: Pristiphora (Pristiphora) anivskiensis Haris, 2006, syn. nov., Pristiphora (Pristiphora) nigrocoreana Haris & Zsolnai, 2007, syn. nov. and Pristiphora grossulariae Anon., 1912 [a primary homonym of Pristiphora grossulariae Walsh, 1866], syn. nov. The lectotype of Pristiphora grossulariae Anon., 1912 is designated. Redescriptions of the adult and immature stages are given. The male is described for the first time. The life history and host plants are summarized. Its close relative, Pristiphora appendiculata (Hartig, 1837), is excluded from the fauna of Japan.

Specimens of Georissus crenulatus have been reared in the laboratory, and aspects of the life history are described. Egg cocoons and pupa (previously unknown in Georissus) are described and compared with those of other hydrophiloids. First instar larvae of Georissus lack cephalic egg bursters and, contrary to current assumption, these seem to be generally absent in Hydrophiloidea. The variation of egg cocoons in Hydrophiloidea is outlined and the evolution of the different types discussed.

Elachista (Elachista) saarelai sp. n. is described on the basis of specimens reared from larvae in southern Finland. The new species belongs to the Elachista tetragonella group, and is a close relative of E. trapeziella Stainton, E. ornithopodella Frey, E. occidentalis Frey and E. kebneella Traugott-Olsen & Schmidt Nielsen. It differs from all these species by details in morphology and life history. The new species inhabits sheltered habitats. Carex digitata and probably also C. pediformis are recorded as its host plants. Diagnostic characters and illustrations are provided for the close relatives of E. saarelai sp. n.
