Head flavo-testaceous, the summit deeply infuscated, the whole more 

 or less mottled with small fuscous spots; antennae dull brownish red, 

 apically infuscated, at base paler, four-fifths as long as the hind femora. 

 Pronotum above brownish fuscous mottled slightly with dusky yellow, 

 the median carina black; lateral lobes brownish yellow below, above 

 occupied by a broad piceous stripe, running from the eyes nearly to the 

 middle of the abdomen, broader and with vague boundaries on the 

 abdomen and partially interrupted by a slender, oblique, brownish yel- 

 low stripe on the crest of the metathoracic episterna. Tegmina but 

 little longer than broad, hardly longer than the prozona, rotund, ovate, 

 black concealed by profuse rufous veins. Legs dull yellowish brown, 

 the middle and hind femora heavily spotted with black, the hind tibiae 

 dull fusco- glaucous, pale at base, the spines black beyond the pallid 

 base, twelve in number in the outer series. 



Head not prominent; vertex slightly tumid, a little elevated above 

 the prouotum, the interspace between the eyes scarcely so broad as the 

 basal joint of the antennae; fasti gium steeply declivent, shallowly and 

 broadly sulcate in advance of the eyes; frontal costa moderately broad, 

 as broad as the interspace between the eyes, shallowly sulcate through- 

 out, slightly and regularly expanding below, obsolescent next the cly- 

 peus; eyes large and prominent, nearly twice as long as the infraocular 

 portion of the genae. Pronotum broadening slightly and regularly 

 throughout, the prozona distinctly longitudinal, almost twice as long 

 as the metazona, its surface very faintly and very sparsely punctate, 

 the median carina sharp but slight and equal; metazona with the 

 median carina not sharp but rather inconspicuous, the surface of the 

 lobe both above and on the sides delicately rugulose; lateral carinae 

 wholly obsolete, the nearly plane disk, passing by a well rounded angle 

 into the lateral lobes; both front and hind margins subtruncate, the 

 latter minutely emarginate in the middle. Prosternal spine not very 

 long, appressed cylindrical, very blunt, a little retrorse; interspace 

 between mesosternal lobes about twice as long as broad. Extremity 

 of male abdomen tumid, strongly upcurved; supraanal plate triangular 

 with subrectaugulate apex, the sides gently convex, gently upturned, 

 the median sulcus extremely broad, short and shallow; furcula consist- 

 ing of the slightly produced inner angulation of the widely parted and 

 diverging halves of the last dorsal segment; cerci rather stout but 

 laminate, tapering at the very base, beyond nearly equal, moderately 

 broad, directed inward and backward and bent obliquely a little down-
