SOME AFRICAN BERS OF THE GENUS ANTHOPHORA. 337 



May 17th. General appearance darker than parthenie ; spines 

 more orange. Through lens, the double row of ventral spines 

 larger and more closely covered with setse than aurelia or jj^r- 

 ihodc. No white line at the sides. Abdominal prologs whitish 

 with black hooks. White spots on body fewer and smaller than 

 in the other species. Dorsal row of spines very noticeably 

 smaller than the tivo rows on each side of it. Spiracles large 

 and black, narrowly ringed with leaden grey. Not much white 

 on head. Prothorax, double ventral spine and setaB of central 

 rows present. On meso- and metathorax the double ventral row 

 has the lower spine rudimentarj^ and placed before the other. 

 Dorsal spine absent. The former has a fairly well-developed, 

 the latter a rudimentary, sub-spiracular. Spines whitish orange, 

 and placed on rather brighter orange patches, the tips of the 

 spines only being whitish ; the two ventral rows are, how- 

 ever, white throughout. Sur-anal flap semi-transparent dark 

 grey ; anal prologs the same colour, with whitish band above 

 black hooks. 



First larva pupated May 17th.

SOME AFRICAN BEES OF THE GENUS 

 ANTHOPHORA. 



By T. D. a. Cockerell. 



The Ethiopian region is very rich in the swift-flying bees 

 with banded abdomen, belonging to the group of Anthophora 

 which Friese has named Amegilla. The typical member of this 

 series, A. quaclrif,isciata, Villers, is very widely distributed, from 

 Germany to South Africa. There are, however, very numerous 

 closely allied forms of local distribution, which probably are 

 adapted to different genera of tropical plants. In the north 

 A. quadrifasciata and the related^, albigena are especially found 

 at flowers of Anchusa, while another member of the group, 

 A. salvice, is said to regularly visit Salvia. Some day, no doubt, 

 observations of this sort will be made on the many tropical 

 species, but at present all that students of bees can do is to 

 describe the insects as they occur in museums, leaving the more 

 interesting work of elucidating their natural history to others 

 and to the future. The material on which this paper is based is 

 in the British Museum. 



Anthophora medicorum, n. sp. 

 $ . Length about 11 mm., expanse 20; mandibles (except apex), 

 labrum (except a dusky spot in each upper corner) and clypeus 

 (except a large quadrate black area on each side above) pale ochery
