178 THE CANADIAN ENTOMOLOGIST. 



Head moderate in size, scarcely retracted ; tongue weak ; palpi small, 

 longer in the ^ . Antennae of ^ bipectinated, of the $ simple. Legs 

 almost equal in length, spurs normal in number but short. 



Primaries with 7 to lo stalked, out of the same point with 6 from the 

 end of the subcostal 33,4 and 5 from the end of the median, 4 more 

 remote from 3 than from 5. 



Secondaries without costal vein, subcostal extended some little dis- 

 tance beyond the end of the cell and forking to give off 6 and 7 ; 3,4 and 

 5 from the end of the median, 5 rather more remote from 4 than is 3. 



For further details I would refer the student to my paper in Proc. U. 

 S. Nat. Mus., X., 335.

 The two species are closely allied, but are, I believe, distinct.

Tongue very short and weak. Legs short and stout, subequal in 

 length ; middle and posterior tibiae with minute terminal spurs only. 

 Tarsi short, the claws split nearly to the base in both sexes. Antennae of 

 the male serrate, of the female simple. 



Primaries with 6 to 10 stalked out of the end of the subcostal^ 6 

 branching off almost immediately, 10 a little further on, 7 more than half 

 way to apex, while 8 and 9 divide just before the apex ; 3, 4 and 5 from 

 the end of the median, 4 nearer to 5 than to 3. 



Secondaries with 8 from the subcostal unusually close to base ; 6 and
