 as the pronotum, rather large, full and rounded ; below the antennse 

 deep shining piceous, elsewhere yellowish gray, the occiput with three 

 distinct dark gray longitudinal bands. Eyes of average size, about as 

 prominent as in N. fasciatus, but rounder than in that species. Maxillary 

 palpi dark reddish-brown, the third joint and the apex and base, respec- 

 tively, of the second and fourth lighter. A dark piceous band starts behind 

 the eye and covers the lateral lobe of the pronotum, except the extreme 

 lower margin, which is light yellowish. Pronotum nearly three-fourths as 

 long as broad, widening slightly posteriorly, dorsum pale yellowish-gray, 

 sparsely covered with black bristles. Tegmina of ^ usually covering 

 about three-fourths of the abdomen, and fitting closely to the latter, pale 

 yellowish, with the upper half or more of the lateral field shining black, a 

 black streak along the dorsal field near the inner margin, and usually two 

 or three smaller black patches near the base. Tegmina of ^ usually 

 covering about one-half the abdomen, the hind margin less convex than in 

 fasciatus, pale testaceous, a shining black stripe along the upper third of 

 the lateral field, a black streak on the dorsal field between its puter and 

 middle thirds, and a few short streaks and spots on the inner two-thirds. 

 Wings absent or fully developed, and extending beyond the tips of the hind 

 femora by more than one-half their length. Abdomen in J glossy black
