Clypeus small, compact, with a median keel, and is indistinctly sep- 

 arated from the frons. Eyes long and oval. Pronotum semicircular, 

 with a median carina and numerous pustules. Scutellum is broad, 

 triangular, with three parallel longitudinal carinae, the sides pustu- 

 lated to the lateral carinae. Elytra short, not covering the abdomen, 

 parallel at the sides, cut off straight behind with the terminal corners 

 rounded, parchment-like, thickly reticulate-veined, claval suture ab- 

 sent, both a macropterous and brachypterous form exists but the 

 long-winged form is known of only a few of the species; in the 

 macropterous form, the elytra are long, membranous, transparent, 

 traversed by three longitudinal and five apical veins; the clavus, 

 which contains a forked vein, is separated from the corium by a 

 distinct suture. Wings are present and are large although shorter 

 than the elytra, vitreous. Abdomen arched and narrowed behind into 

 a blunt tip. Legs short, the hind tibiae with a spine in the middle. 

 Haplotype of the genus: Bruchomorpho oculata NEWM. 



These insects are found on thin, fine grasses, usually in 

 damp or moist pastures and meadows. They are very dif- 

 ficult to take, being very timid and quick in action, leaping 

 with surprising agility, often throwing themselves as far 

 as eighteen inches at a single bound. The brachypterous 

 forms are the ones most frequently collected as they are 

 the most abundant in addition to having only rudimentary 

 wings.
