ELEODES SUBCYLINDRICA Casey. 

 Eleodes suhcylindrica Casey, Annals X. Y. Acad. Sci., \, Nov. 1890, p. 400. 



Form cylindrically convex, rather slender, finely, very strongly 

 alutaceous and smooth throughout, black; elytra castaneous. 



Head moderate, sparsely and rather finely punctate. Antenncc 

 rather long and slender, about as long as the head and prothorax, 

 third joint nearly four times as long as wide. 



Prothorax subcylindrical, about one-fifth wider than long; disc 

 transversely, moderately but very evenly convex throughout, longi- 

 tudinally very feebly convex, very sparsely and extremely minutely 

 punctate throughout; apex very nearly as wide as the base, subtrun- 

 cate between the apical angles; sides evenly and feebly arcuate 

 throughout; hase broadly and very feebly arcuate; apical angles 

 acute, very strongly advanced but not at all everted; basal angles 

 obtuse, not in the least rounded, and not at all jDrominent. 



Elytra more than three times as long as the prothorax and rather 

 less than one-third wider ; hase very feebly emarginate, exactly equal 

 in width to the contiguous base of the pronotum ; liumeri very ob- 

 tuse, not rounded, not at all prominent; sides feebly convergent and 

 arcuate near the humeri, parallel and almost perfectly straight thence 

 to the posterior third ; ajpex narrowed rather graduall}^ in apical 

 third, acutely rounded at tip ; disc with unimpressed distant rows of 

 very small, nearly simple punctures, the intervals with single rows of 

 extremely widely distant but almost similar punctures, the punctua- 

 tion not denser towards the sides. 



Legs long and very slender ; anterior femora with a small but acute 

 tooth slightly beyond apical third, the remaining femora simple, but 

 Avith the groove of the lower edge fine, very deep and conspicuous, 

 extending almost to the base, with the cariniform edges finely, un- 

 evenly serrate; tibia? strongly arcuate, spurs of the anterior short, 

 nearly equal and slender.
