224 NEW SPECIES MELYRIDAE, CHRYSOMELIDAE AND TENEBRIONIDAE 



dorsal plate, broadly and rather parabolically exposed, long-itudinally 

 rugulose. 



Valvular membranes visible between the apices and finely setose. 

 Ventro-lateral surfaces evenly convex, not noticeably swollen ; sub- 

 marginal groove moderate and continuous with the concavity on the 

 under surface of the apex ; surface with very fine and very sparsely 

 placed punctures and setae. Internal margins of the valves contiguous 

 apically and briefly so at base. Genital fissure ample and fusiform, 

 exposing the inferior pudendal membrane. 



Eleodes corvina, new species. Form elongate subovate, about twice 

 as long as wide, moderately convex. Color deep black, rather shining, 

 head and pronotum somewhat duller. 



Head short, wider than long, feebly convex, frontal suture more or 

 less distinct and moderately impressed; surface closely and evenly 

 punctured, punctures almost coarse and more or less coalescent. 

 Antennae moderate in length, reaching to the base of the pronotum, 

 gradually and feebly incrassate; third joint equal to the fourth and fifth 

 taken together ; fifth, sixth and seventh subequal in length and very little 

 longer than wide; eighth subtriangular, ninth triangulo-oval, tenth 

 transversely oval ; eleventh short ovate, about as long as wide, rather 

 obliquely truncate at tip. 



Pronotum moderately transverse, widest at middle, apex almost 

 truncate, apical angles distinct, not in the least prominent and obtuse ; 

 sides rather strongly and broadly arcuate, almost straight posteriorly 

 and convergent to the base, marginal bead fine; base slightly arcuate to 

 subtruncate, obsoletely beaded ; basal angles obtuse and deflexed with 

 the discal surface ; disk rather strongly convex, most strongly so laterally 

 and at the basal angles, where it is quite declivous ; densely, somewhat 

 irregularly punctate, punctures a little larger than those of the head, 

 slightly coarse, rather smaller and sparsely placed centrally, becoming 

 more or less crowded and coalescent laterally. 



Propleura full and convex, more or less but not strongly muricately 

 punctato-rugose. 



Elytra elongately ovate to oval, moderately convex, obliquely and 

 rather rapidly declivous posteriorly, apex rather narrowly rounded; 

 humeri distinct, not in the least prominent; base feebly emarginate and 

 a little wider than the contiguous pronotal base; disk distinctly and 

 strongly sculptured, rather coarsely punctato-rugose centrally along the 

 suture, becoming rugoso-tuberculate laterally and on the apical 

 declivity. 



Parapleura and sterna rather densely and not coarsely punctate. 



Abdomen rather densely punctate and more or less rugose.
