The type form of this species is long-winged ; the short-winged 

 form, vittatus, is, however, much more common. The general 

 color of the short-winged form is a dusky brown to a rusty 

 black, the tegmina and legs sometimes paler. The head is marked 

 with four black longitudinal stripes which are hardly discernible 

 in the darker specimens. The long-winged form is usually nearly 

 black, the head and pronotum clothed with long hairs. The 

 tegmina of the male are as long, or nearly as long, as the ab- 

 domen, while those of the female cover about half the abdomen.
