Iiiflexed flanks not blsulcate, unistriate or with a line of confused punc- 

 tures. 

 Body convex. 



Pygidinm and pronotum more coarsely and strongly punctate. 



nOTellllS Zimm. 

 Pygidium and pronotum very finely punctnlate ; prosternal strije 

 becoming parallel and very close, not divergent anteriorly. 



piilicariiis Er. 



Body subdepressed, elliptical ; prosternal stripe feebly divergent ante- 

 riorly from the middle ; subhumeral stria nearly straight, not inferior. 



cllipticiis Lee. 

 Fifth dorsal and sutural striae siibobsolete near the liase, the foimer however 

 always traceable ; body strongly depressed ; male with a small corni- 

 form frontal process ; prosternal striae very distant and strongly diver- 

 gent anteriorly from the middle ; sternal suture simple ; mesosternal 

 stria entire : apical stria of the pronotum broadly interrupted. 

 Short, broadly oval ; prosternum extremely minutely, sparsely punctu- 

 late, the apical lobe not margined ; elytra without trace of the inner 

 subhumeral stria; pygidium indistinctly punctnlate (decipiens Lee, 



nasutus Horn) plan 11 Ills Er. 



Elongate, narrowly oval ; prosternum densely and strongly punctulate, 

 the apical lobe finely, deeply margined ; elytra with the inner sub- 

 humeral distinct in apical half and very close to the first dorsal ; 

 pygidium finely but strongly and distinctly punctate. 



corniitus n. sp. 

 Elytra with the fifth dorsal and sutural completely obliterated in basal third; 

 body short, strongly convex ; transverse sternal suture double. 



subtropicus n. sp. 



In most of the species the two minute marginal punctures of the 

 pronotum referred to under the various species of Hister, are evi- 

 dent and constant. 



E. corniltus. — Rather elongate, oblong-oval, depressed, shining, black, 

 the tarsi dark rufous ; antennae piceo-rufous, the club pale flavo-testaceous ; 

 integuments very finely, densely punctate throughout. Head not margined, 

 more prominent at the sides above the antennae ; clypeus large, nearly verti- 

 cal, with a short erect process at apex, bearing a short stiff seta, the clypeal 

 suture feeble. Prothorax almost twice as wide as long, the sides feebly con- 

 vergent, broadly, feebly arcuate throughout ; marginal stria deep, inferiorly 

 arcuate in the middle of the sides, broadly interrupted at apex ; two marginal 

 punctures distinct ; disk with a very obsolete impression along the median 

 line in nearly basal half. Elijtra as long as wide, twice as long as the pro- 

 thorax and only very slightly widt-r ; sides evenly, feebly arcuate ; base 

 broadly, angularly emarginate throughout ; inflexed flanks unistriate ; mar- 

 ginal stria inferior, gradually ascending near the base ; outer subhumeral 

 represented by a few remote punctures ; inner distinct toward apex and with
