from the ocellus to the cl3'peu,s, distinctly but not deeply sulcate 

 dorsad, impresseH ventrad, this becoming less apparently toward the 

 clypeus; e3"es moderately' prominent in the male, less so in the female, 

 reniform ovate in outline, ver}' considerably or slightly longer than 

 the infra-ocular sulcus; antennse considerably' (male) or slightly 

 (female) longer than the head and pronotum together, depressed and 

 ver}" slightly expanded proximad. Pronotum moderateh^ deplanate 

 dorsad; cephalic margin very slightly arcuate, caudal margin obtuse- 

 angulate; prozona distinctly but not very considerably longer than the 

 metazona, the latter thickly but not ver}' deeply punctate; median 

 carina distinct, cut onlv by the principal sulcus; lateral carinse distinct, 

 nearly parallel, with a very slight constriction from the first to third 

 sulci in the male, and in the female apparently with a very slight 

 divergence through the entire length, all three transverse sulci inter- 

 secting these carin{\?; lateral lobes about as deep as the dorsal length 

 of the lobe, ventral margin rounded mesad. Interspace between the 

 mesosternal lobes distinctl}' transverse in both sexes; metasternal lobes 

 attingent (male) or subattingent (female). Tegmina falling slightly 

 short of the ai)ex of the abdomen and ver}' considerably short of the 

 tips of the femora in the male, or exceeding the abdomen and ecjualing 

 the femora in the female; marginal field expanded in both sexes, but 

 stronger in the male than in the female; a broken or sinuate inter- 

 calary vein present in both sexes, but more distinct and continuous in 

 the female than in the male; apex rounded, sutural margins nearly 

 straight, wings reaching to the tips of the tegmina when in repose. 

 Abdomen considerably compressed; supra-anal arched, elongate trigo- 

 nal in shape with a longitiidinal median depression; cerci rather slender 

 styliform, reaching to the apex of the supra-anal plate; subgenital 

 plate conic, the apex bluntly tuberculate, and extending very little 

 beyond the supra-anal plate. Cephalic and median limbs of medium 

 size, slender; caudal femora moderately ro])ust, pagina distinctly but 

 rather shallowly sculptured, the genicular region slightly inflated; 

 caudal tibia* distinctly but not considerably shorter than the femora, 

 armed with 8 spines on the hiteral margins; internal spurs unequal but 

 the difierence is not as great as seen in Scylliva and allied genera; 

 arolia of the caudal tarsi of medium size, trigonal. 



(xeneral color wood-brown, touched dorsad with fawn, a distinct post- 

 ocular bar extending caudad to the caudal margin of the lateral lobes, 

 rather irregular and broken on the lateral lobes, clove-brown in color; 

 face spotted with bister; antenna.' dark distad; eyes raw umber; teg- 

 mina with the series of faint dark subquadrate spots on the marginal 

 tield. Cephalic and median lim))s more or less completely and regu- 

 larly annulate with clove-brown, the annuli of the femora weaker than 

 the tibial and tarsal ones. Caudal femora mesad on the dorso-lateral
