 curved, transverse sidcation, its concavity facing forward. Tegniina 

 about four and one-half times longer than broad, inner edge straight 

 for most of the length. Wings extending considerably beyond iSie 

 tegmina in repose. Ovipositor slightly broader in the middle tfian 

 at the base, beyond it tapering regularly to a delicate point ; the 

 denticulations of the edges very slight, the tip of the ujiper edge 

 smooth. 



Length of prothorax, 4.75 mm. ; of tegmina, 28 mm. ; of hind tibiae, 

 14 mm. ; of ovipositor, 8.5 mm. ; greatest breadth of ovipositor, 2 mm.;

C(ELOPIlYLLUM nOV. gcn. (x(<?/((C, (fOkko'^Jj 



Head rather small, the middle of the front thrust forward like a 

 great tubercle ; fastiglum of vertex extending beyond the middle of 

 the basal joint of antennae, tapering, compressed apieally so as to be 

 scarcely more than half as broad as the basal joint of antennae, sulcate 

 above, its sides hollowed. Antennse tery slender. Prothorax flat 

 above, the lateral angles rounded except at the posterior extremity; 

 front border straight, hind bonier well rounded. Elytra ample, 

 broader in the apical than in the basal half, costal margin excepting 

 at base and tip straight, inner margin convex, the extremity of the 

 elytra tapei'ing so rapidly as to be almost docked ; the two principal 

 veins run side by side down the middle of the elytra; wings very 

 large, longer than the elytra. Legs short and slender, the hind femora 

 not half the length of the elytra; fore coxae furnished exteriorly with a 

 single slender spine; legs furnished only with abbreviated spines. Ovi- 

 positor very short, stout, strongly curved, the edges of the apical

The single specimen examined, from having been immersed in alco- 

 hol, has lost its colors, which were doubtless of a uniform green devoid 

 of markings, the principal veins of t)ie elytra probably infuscated and 

 the apical half of the ovipositor blackish. Prothorax with a lightly 

 impressed mediodorsal line. Elytra somewhat more than twice as 

 long as broad, the tip very bluntly angulated. All the spines of the 

 legs very small, scarcely elevated. Ovipositor very broad, its apical 

 half convex, with flattened, squamiform, imbricated tubercles, the 

 edires directed forward.
