Extensive tours were undertaken of the artificial Southern African zone, south of the Zambesi Cunene line. The object was to add to our knowledge of many lesser known species of butterflies that inhabit the more remote areas. It seems desirable that some of the more important finds should be recorded. Hereby unpublished records were combined with the findings and arranged them in the order adopted by most modern writers on this branch of Lepidoptera.
The genus Gongroneura was erected by Buckton in 1903, under the name of Pedalion. (1916) (Figs. 4, 5, 6) The species Centrotusoides wealei Distant was not figured by Distant. This omission is rectified and a redescriptionption presented.The genus Foliatrotus are large robust insects, nearest to Spalarises Dist., but differing in the shape and position of the suprahumeral horns, the shape of the posterior process and the number (2) of subapical cells of the tegmina.The genus Eumonocentrus was erected in 1911 by Schmidt to accommodate his species erect us from the French Congo.
An account is given of incubation experiments carried out on egg samples collected from twenty egg deposits in the outbreak area of L. pardalina. The majority of the eggs (95-100 per cent.) were in diapause, showing that the eggs produced by females in incipient swarms may enter diapause to the same degree as those laid by solitary and transiens individuals reared in the laboratory. Some aspects of the practical significance of these eggs and the presence of BHC on the viability of the eggs are discussed.
Regeneration of the antennae is fairly common among orthopteroid insects, the 'heteromorphous', limb-like organs produced in Carausius morasus. It is, however, less commonly recorded for Acrididae although it has long been known. An early record of its occurrence in Euthystira brachyptera (Ocsk.) is provided by Graber (1867).
Of the forty species of Dorylus, s.latu, the females of only ten are known, and some of these were taken without the workers, so that their identity is doubtful. The importance of this ? from Kinganop lies in settling the question of the correct determination of a ?, taken without workers, and descriptionbed by E. Andre (1900), as D. (Anomma) nigricans III. but transferred by Fore! (1912) to D. 'Wilwerthi Em.
The following notes comprise a third instalment to those published in previous issues of this journal (Taylor, 1949, 1951), and, in some cases, are supplementary to them, additional data concerning several species having been obtained since Parts I and- II were compiled. Forty-four species in all are dealt with below, in varying detail.
Two new species of the leucospila group are here descriptionbed. The new species can be separated from L. leucospila (Wied.) and L. irvingi Curr. (= L. afra Curr., n. syn.), the previously descriptionbed Ethiopian species.
This interesting species is at once distinguishable from other species of the protumnus group by its general darker colour and especially in the female which is almost black; much unlike the other females of the group which display more orange-yellow on their wings. So far the only known habitat of the species is along the northern face of the Swartberg, on the Swartberg Pass (between Prince Albert and Oudtshoorn) where most probably it exists in many spots.
During July and August, 1952, the writer accompanied the Bernard Carp Expedition to Barotseland, Northern Rhodesia. A brief account of the localities visited and the dates, and records of some Trypetidae (Diptera) collected with a new species from Kenya is recorded. 500 specimens of Trypetidae were ultimately brought back from Barotseland.
