AMERICAN COLEOPTERA. 149 



rather strongly rounded and finely margined ; anterior angles distinct, posterior 

 completely undefined ; surface usually lightly transversely impressed at the mid- 

 dle. Presternum very short before the coxa; metasternum sparsely rather finely 

 granulate. Length 2.3-4.3 mm. 



Occurs along our entire Atlantic seaboard, but is evidently more 

 common toward the south. The following localities are represented 

 in the material before me. Massachusetts (Bowditch) ; New York ; 

 Pennsylvania; New Jersey; District of Columbia; Piney Point, 

 Maryland; Ft. Monroe and Virginia Beach, Virginia; St. Cather- 

 ine Islands, Georgia ; Lake Mary, Enterprise and Tampa, Florida. 



One specimen from Mandeville, Louisiana (National Museum 

 collection) is a little aberrant, but is placed here provisionally; 

 another labeled Kansas (Bowditch collection) is not separable from 

 the eastern forms. 



17. E. op if us n. sp.— Similar in color and form to granulatus; best described 

 by comparison with that species. The elytra are distinctly scabrous and opaque 

 throughout, the small granules reaching quite to the apex, the surface of duller 

 lustre than the prothorax, which is plainly punctured, each puncture occupying 

 the centre of a flattened rounded tubercle. In granulatus the elytra are more 

 shining than the thorax, the latter granulate but not distinctly punctured. The 

 pubescence is in opicns evidently longer and less sparse and fulvo-cinereous in 

 color. The head is punctured like the prothorax. The antenna? are similar to 

 those of granulatus, except that the fifth joint is much longer, being quite as long 

 as the third. The prothorax is more widely margined and subexplanate at sides> 

 the hind angles somewhat defined (not at all so in granulatus), the front margin 

 sinuate immediately before the angles (straight in granulatus). In its exceedingly 

 short presternum before the coxaj and its sparsely granulate metasternum opicus 

 agrees with granulatus. The last joint of palpi is distinctly dilated apically, 

 scarcely so in granulatus, agreeing in this respect with the species placed at the 

 head of the genus. Length 3i mm. 



Described from two perfectly identical females from Massachu- 

 setts (Blanchard), Marquette, Michigan (Hubbard and Schwarz). 



The elytra are more conspicuously granulate than in any other 

 species in our fauna, and the peculiar sinuation of the front margin 

 of the prothorax just before the angles has not been observed else- 

 where. 



18. E. luteipeiniis Lee— Eufotestaceous or brownish yellow; prothorax, 

 especially in the male, more or less piceous, the margin frequently paler; under 

 side darker, the legs pale or with the femora darker. Head and prothorax 

 densely granulate-punctate and dull; elytra simply, more sparsely punctate, 

 shining; pubescence gray, moderately well developed. Eyes not very large, a 

 little smaller in the female; front about twice as wide as their vertical diameter
