The new species described herein was found, in the first instance, on cacao (Theobroma cacao, L.) at the Central Experiment Station, Serdang, Selangor, Federated Malay States. Later on, a few specimens were caught on the leaves of annatto (Bixa orellana, L.) plants situated at about two hundred yards from the area planted with cacao.

Many new species of Typhlodromus were described in recent years and these can readily be assigned to the species groups established by Chant (in press). Recently I received some slides of mites collected by Dr. Stanley Flanders, Citrus Experiment Station, Riverside, California, in Hong Kong in 1953. These mites are of the subgenus Typhlodromus as defined by Chant (1957), of a hitherto undescribed species that does not fall into any of the groups listed and that is of particular importance to those interested in the systematics of the Phytoseiidae.

A new species Neomyrmecridium asymmetricum, found on decaying leaves of Theobroma cacao, is distinguished by grouped conidiophores and polyblastic production of narrow clavate to subclavate, 1-septate, asymmetrical, and yellowish or subhyaline conidia. An ITS- and LSU-based phylogenetic analysis, description, and illustrations are provided. A key and illustrations to Neomyrmecridium species are also presented.

Lasioseius is a genus widely distributed across the continents, found in many types of hosts. Two new species of blattisociid mites from Brazil, Lasioseius jorgeamadoi sp. nov. and Lasioseius gabrielae sp. nov., are described based on the morphology of adult females collected on buds of cocoa plants, Theobroma cacao L. (Malvaceae) and inflorescences of ornamental plants (Heliconiaceae and Musaceae) in the State of Bahia, and collected on sugar cane, Saccharum officinarum L. in the State of São Paulo. A key for the separation of females of the 14 species of Lasioseius recorded in Brazil is provided.

Pterula echo sp.nov. is described from culture. It was isolated from Theobroma cacao L. from Trinidad. Fruitbodies formed on sterile cocoa twigs and on nutrient agar. Optimum temperature for fruiting and sporulation was 20 to 25 °C. Meiosis was normal and chiastic. Phenotypic plasticity of some taxonomic characters in Pterula is discussed.

This new raspberry pest has been discussed in detail in Bulletin 126, issued in February, 1897, from the Cornell Agricultural Experiment Station. The life-history and habits of this Anthomyiian are fully illustrated in the Bulletin. At the time the Bulletin was written; however, the name of the insect had not been determined. In April, 1897, I reared several more of the flies and sent some to Mr. D. W. Coquillett at Washington. He soon reported that the insect was a new species of Phorbia, and sent me the following technical description of the fly, which he had drawn up from the specimens I sent him.

Cacao was introduced into West Africa in the latter years of the last century and for a time remained relatively free from pests and diseases. It is, in fact, only recently that two major scourges have developed to a point where they are threatening the future of the cacao industry in the Gold Coast and Nigeria. The first, the cacao Mirids (Sahlbergella singularis, Hagl., and Distantiella theobroma, Dist.) is outside the range of the present paper. The second, and most important, is a virus disease, known as “Swollen Shoot”, which is transmitted from tree to tree by at least three species of mealybugs of the family Pseudococcidae.

A trifle more than two years ago the writer first entertained the idea of preparing a synopsis of the Orthoptera of Nebraska, with the intention of publishing it as a special bulletin from the Agricultural Experiment Station. With that end in view, work was immediately begun; and in the course of a few months the greater portion of the manuscript was ready for the printer. At this time other matters that were considered of more immediate importance came up at the Station, and that of the Orthoptera was laid aside. It has now been lying nearly two years.

In April, 1894, the Biological Experiment Station ofthe University of Illinois was established on the Illinois River at Havana, Illinois. Collections were made from various substations, located upon the river and adjacent lakes, at stated periods, the intervals varying from one week to one month. Nearly all of the towings made were examined by me, and the list of animals includes ninety species of Rotifera and eighty species of Protozoa.Among the Rotifera there are three presumably hitherto undescribed species of the genus Brachionus. This genus is well represented by ten species and two varieties, and affords an interesting field for study.

Actualmente hay más consumidores que buscan cosméticos que tengan productos naturales, sin embargo hay poca investigación en este rubro, y con las normativas actuales hay que mostrar que el dermocosmético es estable durante la vida útil del mismo. Por tanto el objetivo de la investigación es conocer las propiedades fisicoquímicas de un extracto de Bactris guineensis, para formular una forma dermocosmética gel y otra en crema y determinar su pre estabilidad con el extracto. Se hicieron los análisis fisicoquímicos del extracto acuoso liofilizado de Bactris guineensis, luego se realizaron las formulaciones crema y gel y finalmente se aplicó una prueba de pre estabilidad que consiste en un centrifugado a 3000 rpm durante 30 minutos. Los resultados mostraron estabilidad en las dos formulaciones, Se opta por la crema, debido a la amplia utilización de esta forma dermocosmetica en otros extractos como achiote (Bixa orellana), chupasangre (Oenothera rosea), culantro (coriandrum sativum), maracuya (Passiflora edulis), tomate (Lycopersicum esculentum, Solanáceae) y arazá (Eugenia stipitata, Myrtáceae), piperaceae (Piperaduncum L.), ishpingo (Ocotea quixos), cacao (Theobroma cacao l.), hierba de la plata (Equisetum bogotense) y pera (pyrus communis), Talipariti elatum Sw.

A new species of aphis, Macrosiphum martorelli is described from the Dominican Republic. This yellow-green aphis attacks the flowers, young buds and tender foliage of "cacao", Theobroma cacao L. causing considerable injuries. Although of no economical importance at present it could be of some importance to the "cacao" industry in the future.
