Somewhat above tlie medium size. Head not prominent ; vertex feebly 

 tumid, barely elevated above the pvonotum, the interspace between the 

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

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

 broad, subspatulate, with distinct but low and coarse bounding walls; 

 frontal costa broad, equal, rather broader than (male) or as broad as 

 (female) the interspace between the eyes, flat throughout or faintly sul. 

 eate down the middle below the ocellus, biseriately punctate above; 

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

 infraocular portion of the genae; antennae nearly four-fifths (male) 

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

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

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

 aiigulato-arcuate; median carina distinct, slight, equal, percurreut; 

 lateral carinae scarcely indicated and on the metazoua wholly obsolete; 

 whole disk gently punctate, the prozona more sparsely than the raeta- 

 zona; prozona distinctly longitudinal (male) or quadrate or feebly lon- 

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

 the metazoua. Prosternal spine moderately long, appressed conical, 

 blunt, erect; interspace between mesosternal lobes fully half as long 

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

 Tegmina abbreviate, a little shorter than the prouotum, rounded ovate, 

 half as long again as broad, the apex not at all produced, slightly over- 

 lapping at their inner margins. Extremity of male abdomen a little 

 clavate, somewhat recurved, the supraanal plate triangular, of about 

 equal length and breadth, the apex bluntly pointed, the sides very 

 nearly straight, with a slight transverse median ridge not reaching the 

 sides; furcula formed of two rather distant, nearly straight, subconical 

 processes, scarcely reaching the transverse ridge; cerci simple, conical, 

 scarcely curved, tapering more on the basal than the apical half, about 

 half as long as the supraanal plate; subgenital plate broader than 

 long, the lateral and apical margins on the same plane, well rounded or 

 feebly 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 

 fulvous, lutescent basally, darker apically; a broad blackish fuliginous 

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

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

 pleura are marked as in .17. lexanm and the tegmina areunicolorous and 

 of the color of the disk of the pronotiun. The hind femora partake of
