231 Die Bienen Afrikas nach dem Stande unserer heutigen Kenntnisse. ,., 



This species might be taken for a large variet}^ of C. scutellnris F., but the very different form of the 

 apex of the scutellum distinguishes tJie tvvo; in scutellaris the middle is incised, and the sides roundly curved, 

 ending in a shaip point; scutellum, too, wants the patch of pubescence: C. jaegerskiveldi MoRlCE has a patch of 

 pubescence on the scutellum, but it has the latter formed as in scutellaris. According to MORICE the results of 

 the Swedish Zool. Exped. to Egypt and the White Nile (No. 14, p. 9) none of the previously described species 

 of Crocisa possess this patch (but see Vachal, Ann. Soc. ent. Fr., 1903, p. 381), but it is to be found in the Cape 

 C. picta Sm. The pubescence on the latter is blue, and the scutellar incision is wide and not clearly as in 

 scutellaris; it is also much larger.
