Description. — d\ Size large (for the genus) ; form elongate-lanceolate, 

 moderately depressed; surface subglabrous. Head with edge of 

 occiput visible cephalad of pronotal margin; interocular space 

 slightly less than that between antennal scrobes; antennae consider- 

 ably exceeding the body in length. Pronotum transversely subovate, 

 very slightly produced and narrowed cephalad, cephalic margin sub- 

 truncate, lateral margins gently arcuate, caudal margin arcuate, 

 caudo-lateral angles rounded, placed caudad of medio-transverse line 

 of pronotum, greatest length contained one and one-third to one and 

 one-half times in greatest width ; disk of pronotum distinctly deplan- 

 ate, deflected laterad, divergent oblique sulci distinctly indicated. 

 Tegmina elongate lanceolate, lateral margins subparallel, length four 

 and one-half to five times that of pronotum, greatest width contained 

 three and one-quarter to three and one-half times in length; costal 

 margin arcuate proximad, nearly straight beyond, apex rather narrowly 

 rounded. Wings ample, ulnar vein with four to six complete and 

 one to three incomplete rami. Supra-anal plate transverse, truncate 

 to very obtuse-angulate distad. obliquely emarginate laterad, the angles
