This paper attempts to clarify several matters which have arisen in the course of preparing a catalogue of Ethiopian Bombyliidae. A large number of type specimens have been examined and many hitherto uncertain taxa have been placed, often involving synonymy which will be given in the catalogue. However, some of these synonymies require clarification beyond that appropriate to or possible in a catalogue, and in some instances require creation of new taxa for satisfactory resolution. In addition, some nomenclatural matters are the cause of some new taxa, including a new genus and the opportunity is taken to comment on a major re-allocation of species from the genus Exoprosopa Macquart.
All instars of the ixodid tick Boophilus microplus are redescriptionbed, with the aid of a scanning electron microscope, from material originally obtained from Zululand (Natal, South Africa). The course of feeding of all stages, moulting of larvae and nymphs and the detachment of engorged adult females of this tick were studied under laboratory conditions using a Guernsey calf as host.
Apart from the studies carried out by Goodier (1963, 1966, 1967) on the distribution and seasonal incidence of Tabanidae in Rhodesia, only Cookson (1967), working in the Vumba mountains, has written on this topic in the Rhodesian context. The present study was conducted at Rekomitjie (16ï¿½ 10'S 29ï¿½ 25'E altitude 503 m) which lies in the Zambezi Valley, about 80 km downstream of the Kariba dam in Rhodesia.
Lucilia spinicosta Hough was based on a male and a female from Somalia. Through the kindness of Dr D. C. Rentz, Academy of Natural Sciences, Philadelphia, Mr A. C. Pont (British Museum) was able to borrow the male specimen labelled as ""lectotype"". He found that it does not represent a species of Lucilia, but belongs to the genus Phumosia sensu Zumpt (1956b). It was sent to us for confirmation and also permission was given to dissect the genitalia. This has been done with the result that Phumosia spinicosta (Hough) is conspecific with P. pretoriensis Zumpt.
