Ilalictus jlavovittatus, W. F. Kirby. 



I have examined the female type from Socotra. It is a 

 true Ilalictus-, with normal venation, but remarkable for the 

 character of the abdomen, the segments very black, witli the 

 margins narrowly ivory-colour, without hair-bands. Area of 

 metathorax large, gianular-striatulate; hind spur minutely 

 short-ciliate. H. vittalus, Smith, from the Cape of Good 

 Hope, has similar tegumentary bands, but it is not so large, 

 and the bands are light yellow, the first quite golden yellow. 

 The specimen examined, in the British Museum, is marked 

 vittatus, variety. 



Ilalictus niloticus, Smith, 1879. 



The type, a male, is a green insect with a curious large 

 head, and a peculiar thing is that the upper ends of the eyes 

 are green. There is a large yellow spot on lower part of 

 clypeus.

COLLETES. 



The following table for the separation of some little-known 

 species was prepared at the British Museum. The Radosz- 

 kowski species should be authentic, as they were received 

 from the describer : — 



Very small, anterior wing o mm.: densely- 

 covered with white hair ; bases of 



abdominal segments, where exposed, 



densely punctured ; nervures and stigma 



pale ferruginous; second s.m. broad, 



receiving r. n. in middle ; posterior face 



of metathorax covered with hair. J . 



(Askabad.) askJtabadensis, Rads. 



Larger, not thus hairy ; malar space in no 



case long 1. 



1. Thorax above covered with short pale 



ochreous moss-like hair, like the 



American C. aberrans, Ckll. ; anterior 



wing 7 mm. long; abdomen with broad 

 - bands of greyish-white toinentum, the 



first segment densely and coarsely 



punctured, second densely and finely, 



in strong contrast ; nervures and stig- 

 ma dark, paler basally ; antennae very 



short. § . (Askabad.) curinatus, Rads.
