21 G Mr. Edward Saunders on 



ture like that of the disc but impunctate, lateral fringes very 

 slightly indicated. A very well-marked species on account of the 

 very unusual shape of the 8th ventral segment with its somewhat 

 bottle-brush arrangement of hairs at the apes, and the very elongate 

 armature.

Andrena iota. 



Slightly smaller than the preceding, head clothed with pale hairs 

 clypeus shining, largely punctured, antennas with the 2nd joint 

 of the flagellum slightly shorter than the 3rd and 4th taken together, 

 the 3rd not quite so long as the 4th, mesonotum dull, finely rugu- 



lose, propodeal area finely rugulose, abdomen finely rugulose, 

 impunctate, more or less shining, impressions discoloured, well 

 marked at the sides, less sculptured than the rest of the segments, 

 lateral fringes hardly noticeable. Exceedingly like alpha but clypeus 

 built on a difterent plan not raised on the disc as in that species.

Andrena kappa. 



Almost identical with the preceding but differing in the slightly
