The habit of this genus is at first sight very much that of one 
of the gibbous Erotyli; but it is heteromerous, and belongs to the 
present tribe, and, with many others'equally distinct, may have 
been arranged under Helops. It however possesses very few cha- 
racters in common with the genuine species of that genus, H. cha- 
lybeus, &c., differing in antennæ, labium, mentum, palpi, and genea 
ral habit.
