longitudinal striation. The first abdominal segment is largely 

 and irregularly punctured above, the second also irregularly but 

 not so largely, those following more finely and closely. The 

 impressed apices of all the segments are narrowly fasciated or 

 ciliated with whitish hairs, and there is a similar narrow fascia 

 at the base of the second segment. The head, thorax, and bases 

 of the legs (including the femora) are clothed beneath with 

 moderately long white hairs; those on the tibiae and tarsi are 

 also white, but shorter. The posterior ocelli are about as far 

 from each other as from the compound eyes. The legs and 

 antennae seem perfectly simple: in the latter joints 4 to 12 are 

 about equal and about as broad as long; joints 3 and 13 are a 

 little longer than the others, about half as long as the scape. 

 The wings are hyaline, with fuscous nervures and slightly 

 clouded apices. [Sierra Leone]. 



30. Xylocopa aestuans L. Three dV, Khartum 31 i, ed Dueim 



10 ii; seven 99, Cairo Hi; Khartum 1 and 2 ii; Abba Island 



11 ii. [Western and Central Asia, Northern Africa]. 



31. Xylocopa hottentota Smith. One 9, G-ebelein (White Nile) 

 23 iii. [Natal, Angola, Sierra Leone, Aden]. 



32. Xylocopa caffra L. One 9, Abba Island 12 ii. (The spe- 

 cimen is smaller than any at South Kensington, but I see no diffe- 

 rence in the structure or coloration). [Central and Southern Africa]. 



33. Anthophora nubica Lep. One cT, Khartum 2 ii; four 99, 

 Khartum 31 i, 1 ii. [Algeria, Nubia, Senegal]. 



34. Anthophora picicornis Fedt. (?). One cT, White Nile neal 

 el Gerassi about 50 miles South of Omdurman 4 iv. (I have not 

 seen the types of picicornis: but description seems to suit). [Asia, 

 Turkestan]. 



35. Megachile argentata F. One cT, Abba Island 12 ii, one 

 9, Khartum 1 ii. (I see no reason to doubt that these are iden- 

 tical specifically with European argentata. If not, they arc ai 

 least very closely allied to it). [Europe, Northern and Central 

 Asia, Northern Africa]. 



36. Megachile bicornuta Friese. One 9, Abba Island 12 ii 

 |Senegal, Sudan: Khartum].
