5 . Nigra ; mandibulis fusco-ferrugineis ; pronoto, abdomine, 

 femoribus, tibiis tarsisque rufo-ferrugiueis ; postscutello tegulis- 

 que obscure fusco-ferrugiueis ; alis fusco-violaceis. 

 Long. 15 mm. 



? . (ylypeus transverse at the apex, without lateral teeth. 

 Second joint of the flagellum nearly twice as long astlie 

 third, apical joint equal in length to the penultimate. Poste- 

 rior ocelli a little nearer to eacli other than to the eyes. 

 Median sei^ment longitudinally striated, the enclosed area 

 very broadly rounded at the apex, no spine or tubercle on 

 the sides of the segment. The spine on the liind cox?e 

 originates close to the apex. Second abscissa of the radius 

 almost equal to the third ; cubitus of the hind wing originating 

 at a distance beyond the transverse median nervure equal to 

 nearly two and a half times the length of that nervure. 



J/ah. West Africa, Senegal [Guevin). 



I have no doubt that the specimen in the British Museum 

 mentioned by Bingham belongs to Guerin's species. Al- 

 though his description is very brief, it would not fit any 

 other African sj^ecies known to me, and corresponds in every 

 point to the specimen mentioned above.

$ . Nigra ; abdomine, femoribus, tibiis tarsisque rufo-ferrugiueis ; 



alis fusco-violaceis. 

 Long. 12-15 mm. 



y . Clypeus with two distinct teeth on each side. Second 

 joint of the flagellum nearly half as long again as the third, 

 apical joint no longer than the penultimate. Posterior ocelli 

 a little further from each other than from the eyes. Median 

 segment with short longitudinal stride at the base, the rest of 

 the enclosed area coarsely reticulated, with a small depression 

 at the apex ; a spine on each side of the posterior slope. 

 Spine of the hind coxse originating close to the apical angle. 

 Third abscissa of the radius longer than the second, cubitus 

 of hind wing orioiuating at a distance from the transverse 

 median nervure equal to at least three times the length of 

 that nervure.
