I believe that this species is identical with semirufus Friese, described from 

 Egypt. But in the present specimen the apical segments of the abdomen are 

 thinly clothed with fulvous hairs. If these were rubbed off, Friese's description 

 would suit the specimen exactly ; and I believe that this had happened in the case 

 of his " type," which was taken by myself. I have, however, no longer any speci- 

 men of semirufus <S or ? in my own collection, so that I may be mistaken. But 

 under the circumstances I think it would be unwise to describe the present insect 

 as a new species. (As to the name Lasius cf. Tram. Ent. Soc. Load., 1915, p. 421.)

The colour of the abdomen in this insect gives it a curious resemblance to 

 certain species of Andrena (e.g. bipartita, sckenki, helouanensis, etc.). Probably it 

 varies somewhat in individuals, but in the present specimen the basal segment 

 of the abdomen is red entirely, except for a bilobed or " bi-ramose " black mark 

 which surrounds its attachment to the thorax, but does not extend beyond the basal 

 (declivous) portion of its surface, and is therefore not visible in the direct dorsal 

 view. Segment 2 has on each side (just over the spiracle) a sharply defined 

 longitudinal black oval spot, otherwise it is red entirely. Segment 3 is red, except 

 for a black subtriangular mark in the middle of its ventral plate. Segment 4, 

 above, is clouded with black from its apex almost to its base ; beneath, it is also 

 clouded, but less extensively. The three apical segments are almost entirely black. 



The head and thorax are clothed with a rather thin pale pilosity, which is 

 longest at the sides and beneath. The basal segment of the abdomen is clothed
