Some what above the mediuin size. Head n<»t ]U'oiuiiieut ; vertex feebly 

 tumid, barely elevated above the proiiotum, the intersi)aee between the 

 eyes slightly broader than (male) or fully half as broad again as (remale) 

 the first antennal Joint; fastigium rather steeply declivent, shallow, 

 broad, subspatulate. with distinct but low and eoarse bouiuiin,:;' walls; 

 frontal costa br(>ad, ec^ual, rather broader than (nuii^'l or as broad as 

 (female) the interspace between the eyes, flat throughout or faiiitl}' sul. 

 eate d()wii the middle below the ocellus, biseriately punctate above; 

 eyes moderately large, modeiately prominent, a little longer than the 

 infraocuhjr portion of the genae; antennae nearly four lifths imale) 

 or four-sevenths (iemalc) as long as the hind femora. Pronotum very 

 sitnple, enlarging backward uniformly but slightly, and less so in the 

 male than in the female: front margin truncate, hind margin gently 

 angulato-arcuate; median carina distinct, slight, equal, ])ercurrent; 

 lateral carinae scarcelv indicated and on the metazona wholly obsolete; 

 whole disk gently punctate, the i>rozoini more sparsely than the meta- 

 zona; proz<Mja distinctly longitudinal (male) or <iua<lrate or feebly lon- 

 gitudinal (female), fully (male) or about (female) half as long again as 

 the metazona. Prosternal spine moderately long, appressed conical, 

 blunt, erect; interspace between mesosternal h)bes fully half as long 

 again as broad (male) or transverse but shorter than the lobes (female). 

 Tegmina abbreviate, a little shorter thau the ])ronotum, roundetl ovate,

 teebly angulate apically, entire, the lateral margins incurved basally. 



The general color above is either a very pale brownish yellow or a 

 brownish griseous; below dirty yellow with a greenish tinge: antennae 

 Uilvous, iutescent basally, darker apically; a broad blackish fuliginous 

 belt runs from behind tlie eye across the lateral lobes of the pronotum, 

 generally broadening slightly and fading a little on the metazona. The 

 ]>leura are marked as in .1/. te.iuinuH and the tegmina are unicolorous and
