The remarkably and prominently keeled fastigium, broad 
serrated antennæ, markings of the pronotum, and armature 
of the hind femora and tibiæ, also the elongated 
curved genicular lobes, appear to render this a well-marked 
species, and, perhaps, with the following the type of a sub- 
genus. | 
CORYPHISTES NIGROCONSPERSUS, 8). nov, 
Male and female. Smoky brown; in general form resem- 
bling preceding. Head pale (mas.) or dark (fem.) brown. 
Fastigium blackish, subrectangular above, separated from 
occiput by a more or less distinct furrow; distinctly keeled 
only towards apex, in front contracted to an obtuse ridge, 
then expanding between the antennæ forms a distinct cal. 
losity, with the ocellus in the central depression, the dis- 
tinct (mas.) or indistinct (fem.) sinuous lateral ridge extend- 
ing to the margin of the face. Occiput and sides of head 
nearly smooth, dull; a narrow black median stripe from base 
of fastigium to pronotum, a slightly curved, irregularly 
bounded brownish band on either side above; laterally a 
broad, parallel-margined black band from the base of the 
antenne, interrupted by the lower part of the eyes, and a 
narrow black submarginal, more irregular one, starting con- 
jointly with the former. Eyes oval, dark bronzy-brown; 
lateral ocelli rather small, bright brown, adjoining the 
lower border of an elongate black spot on the side of the fas- 
tigium. Antenne dark brown, mottled paler, ensiform ; 
marginal lamina very thin, basal joint subconical, joint 2 
very short, not much thinner than the first; joint 3 over 
three times longer than the preceding together, triangular, 
broad; joints 4-7 quadrate, angular, subequal; joints 8-9, 
10-11, 12-13 successively narrower, longer than wide, quad- 
rangular; joint 14 half as wide as preceding, remainder 
gradually diminishing in dimensions, last. ones very mi- 
nute. Pronotum darker than the head, ‘almost smooth, 
rounded in front and behind, with a few minute tubercles 
above and two broad pale stripes to posterior transverse 
furrow, also the black cephalic stripes more or less distinctly 
continued to the hind margin. Elytra ochreous-brown, with 
numerous small spots scattered over all; apex obtuse. Wings 
pale greenish-brown ; veins and veinlets dark, not bordered. 
Legs, also face and underside, more or less beset with browa 
hairs. Fore and middle legs unarmed. Hind femora stout, 
as long, or longer than, the body; external genicular lobes 
moderately long, curved, gradually narrowed to the sub- 
acute apex; internal lobes large, subquadrate; external 
ridges minutely spinose, densely hairy above; discal area 
white (mas.) or pale ochreous (fem.), with 16 black, narrow,
