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 lielops. It however possesses very few cha- 

 racters in common with the genuine species of that genus, H. clia- 

 lybeus, &c., differing in antennae, labium, meutum, palpi, and gene- 

 ral habit.
