In volume No. III of the Journal of this Society for 1940, you will find two very interesting articles on the history of entomology in South Africa. The first is a presidential address by our esteemed friend Dr. Janse on the early development of entomological science in this country and the second is an article by the late Mr. Lounsbury on what he called ""the pioneer period of economic entomology."" Janse concludes his address by saying that he hoped that from time to time, other articles will be written, filling in the gaps and working out in more detail, the history of entomological research in South Africa.
Typus generis: Thrips ornatus Jablonowski, 1894. Uzel placed three new species in this genus, namely tiliae, degeeri and saltator, but did not designate a type species. In his catalogue of the European species Priesner (1925) listed ornatus (Jabl.) as typus generis; in his Genera Thysanopterorum (1949) he listed as type species tiliae Uzel, hut in a recent letter Dr. Priesner advised me that this should be altered to read Thrips ornatus Jablonowski, 1894.
During recent collecting in the Eastern Districts of Southern Rhodesia two species of the genus Bittacus Latreille have been taken. One species (B. vumbanus) is new to science and of the other (B. solitarius Tjeder) the males have been collected for the first time. The capture of these two species in Southern Rhodesia increases the number of Bittacus-species known from the country to five, with the occurrence of a sixth (B. testaceus Klug) requiring confirmation. The species known with certainty to occur here are: Bittacus weelei Esb.-Pet., B. armatus Tjeder, B. solitarius Tjeder, B. woodi Smithers and B. vumbanus spec. nov.
The data on which this paper is based were collected in and around Salisbury, Southern Rhodesia, during the latter part of 1957 and early 1958 whilst carrying out a preliminary study of Colias electo (L.) as part of an investigation into the insects associated with lucerne. In addition to laboratory and insectary study of the life history of the species, observations were made in a small field of recently-planted lucerne about 18 miles from Salisbury. Descriptions of the stages of C. electo have been given by van Son (1949), Jarvis (1953) and Pinhey (1949) and so are not included in the present paper.
Locusts have plagued man from the earliest recorded times. The Desert Locust (Schistocera gregaria Forsk.) is repeatedly referred to in the Bible and was shown carved in stone in ancient Egypt. The Red Locust (Nomadacris septemfasciata Serv.), on the other hand, inhabits Africa south of the Sahara, a region for which there are no written records more than a few centuries old.
During the early part of November 1953 while engaged upon an aphid survey of cereal lands in the picturesque Langkloof Valley of the South Eastern Cape, I was able to do a little collecting of grasshoppers in the veld adjoining the lands. Some of the new material which was collected from this area and the adjoining Great Karroo is descriptionbed below. With one exception, that being material donated by the Division of Locust Control and Research through the kindness of Mr. J. H. Kruger, all the material has been collected by myself and to avoid repetition I have omitted the collectors name from nearly all the descriptionptions.
In this paper the writer has attempted to bring together all the world species of Chirothrips in a key, in order to encourage students to study this interesting genus, and to facilitate the identification of some of the more difficult species.
Three new species are descriptionbed and figured. These are: Anandia bathurstensis, Bechsteinia grahami and Chaussieria capensis. The following known species are also descriptionbed: Anystis baccarum (Linn.); Neocheylis natalensis Trï¿½gï¿½rdh; Cheyletia wellsi Baker and Cheletomorpha lepidopterorum. (Shaw) . Keys to the genera and species of Anystidae, Pseudocheylidae and Cheyletidae associated with South African plants are given.
Keys to the genera and species of Trombidiidae collected from South African grass and soil are given. Five new species are descriptionbed and figured: Ettmï¿½lleria pretoriae, Allothrombium lawrencei, Microtrombidium grahami, M. potchefstroomense, M. spinosum and Enemothrombium curiosetosum.
Hesse (1938) descriptionbed Gnumyia fuscipennis, the second species of the genus, from three males and remarked that females of both fuscipennis and of the genotype, G. brevirostris Bezzi (1921) were unknown. Among material received from the British Museum (Natural History), through the kind offices of Mr. H. Oldroyd, are two males of fuscipennis together with a female which is undoubtedly a Gnumyia, thus constituting the first record of a female of this genus. This female is descriptionbed here as that of fuscipennis Hesse; some notes on the males are also included.
The group of genera including Corsomyza Wiedemann, Megapalpus Macquart, Hyperusia Bezzi, Callynthrophora Schiner and Gnumyia Bezzi are closely related forms apparently endemic to Southern Africa. The most northerly record of any species of this group of which I am aware is that of Corsomyza ruficornis Bezzi, descriptionbed from the Victoria Falls, Northern Rhodesia (Bezzi, 1921). Paramonow (1954) descriptionbed the genus Pusilla from Katanga in the Belgian Congo, referring it to the subfamily Usiinae. Hesse (1938) removed the entire Corsomyza-group from the Usiinae to the end of the Bombyliinae, thus at the same time removing the Usiinae from the list of subfamilies recorded from the Ethiopian Region, so that Pusilla is at present the only Usiine genus known from Africa south of the Sahara.
This short paper is based on a small collection of Psocoptera made by Mr. E. C. G. Bedford and Mr. D. P. Annecke and sent to me for identification. The specimens were obtained from parasite rearing-boxes containing twigs of Australian chestnut (Castanospermum australe) infested with Icerya seychellarum (Westw.) collected at Pietermaritzburg, Natal.
Domrow (1958b) notes the interesting fact that several genera of mites parasitic on Australian bats also occur on African bats. Comparison of the mesostigmatic bat parasites descriptionbed from Australia and Africa indicates that not only the genera, but also some of the species, may be common to both continents.
