Elongate, subparallel, pubescent species having the head por- 

 rect, wider across the eyes than long, its front subvertical, ver- 

 tex with a short median impressed line ; eyes very large, almost 

 vertical ; pronotum trapezoidal, twice as wide at base as long, 

 its sides not carinate, hind portion convex, rugose, calli united 

 at middle ; scutellum large, triangular, almost flat, finely 

 rugose ; elytra entire, surpassing abdomen, cells of membrane 

 both large, nearly equal in size, their tips angularly rounded. 

 Two of the four North American species are known from our
