Closely resembles Icli. rtijivenfri's Brulle, of which it may be a va- 

 riety, but the annulus of the antennje is larger, the central area of 

 metathorax is smaller and less quadrate, and the legs and the basal 

 segment of the abdomen are rufous instead of black. The size and 

 general appearance is much the same in both species.

This may be identical with Ich. detritus Brulle, but is rather doubt- 

 ful. It is however distinct from any other species known to me. 



69. Ich. Syphax, n. sp. 



Black, glossy ; antennfe involute, with a whitish annulus ; wings subhya- 

 line ; abdomen ferruginous ; central area of metatliorax large, quadrate.
