It is obvious that much confusion exists in the classification of many African Membracids. This is largely because the older workers on the group provided inadequate descriptionptions, and failed in most cases to figure the species, or figured them so badly as to be useless as an aid to their determination. The only course open was to get photographs of them. The authorities of the British Museum undertook this work and all the desired species have been photographed and the correct generic position of a number of species could be obtained. In this paper i hope to clear up some of the more obvious errors, without, attempting to arrange the genera in their natural groupings, which are still not fully understood.
An army worm survey was conducted in and around Pretoria from 1944 to 1947. No evidence pointing to the existence of a permanent habitat in the Pretoria region could be found although outbreaks occurred in this region during each of the four years under review.
This genus was erected by Emery (1912) to include seven species, of which six had been originally descriptionbed as belonging to the genus Atopomyrmex E.Andre. Recently I received two specimens of an ant from Dr. J. C. Faure, collected at Marieps, E. Transvaal, which appeared to have some of the characters of both Terataner and Atopula, and therefore led me to examine more closely the characters of those genera as set forth by Emery in the Genera Insectorum (1922). The conclusion arrived at is that Terataner bottegoi Em. and the new species transvaalensis descriptionbed be!ow should be placed in a new subgenus Tranetera.
The present paper contains notes and descriptionptions of South African Emesinae. Very few species of this fascinating subfamily have been descriptionbed from Southern Africa, but I have every reason to believe that their number must be considerable.
Recently we published a preliminary study of the Ethiopian Laelaptid mites parasitic on vertebrates (1951). It was quite clear to us then that this was but a beginning. Many more new genera and species would be discovered and descriptionbed, and there would have to be several taxonomic changes before we could say that we had a sound knowledge of the Ethiopian fauna of this group.
Short-horned grasshoppers commonly occur in habitats of small extent, separated by different environments, and not constant for long periods. Colonisation of new suitable areas appears to be carried out by individuals frequently moving across non-suitable areas. Movement to suitable areas appears to be partly done by directive movements in response to visual stimuli, more probably to colour than to shadow.
The author (1951) descriptionbed two new species namely Pscudomenopon rowani Keler and Parricola zumpti Keler, both found on the flightless Tristan Rail, Atlantisia rogersi Lowe. These two species are mentioned in this paper in order to give a full account. In the present paper, I am giving a survey of all Mallophaga received from the Tristan da Cunha Group adding a descriptionption of a new Austrogoniodes subspecies from the penguin of Dyer Island, Spheniscus demersus L. This is advisable because I want to compare it with another new Austrogoniodes species from the penguin Eudyptes cristatus cristatus Miller, of Tristan da Cunha.
