E. COarcticollis n. sp. — Oblong-oval, black, strongly convex, highly 

 polished throughout. Head small, about one-half as wide as the prothorax, 

 wider than long, rather convex, finely, deeply and densely punctate ; epistoma 

 broadly, very distinctly and evenly arcuate at apex ; eyes small, the upper 

 fold extremely short and feeble ; antennae short, very robust. Prothorax twice 

 as wide as long, the apex five-sixths as wide as the base, evenly, feebly but 

 distinctly emarginate in circular arc ; base truncate, the basal angles slightly 

 obtuse, small, not at all rounded and distinctly prominent ; sides rather 

 strongly arcuate, more convergent and straighter anteriorly, distinctly but 

 broadly sinuate before the base ; disk much wider at basal third than at 

 base, finely, rather sparsely punctate near the middle, the punctures becom- 

 ing slightly larger and very dense but not coalescent laterally. EUitra nearly 

 three and one-half times longer than the prothorax and, in the middle, very 

 distinctly wider, ovoidal, acutely rounded at apex ; sides parallel and very 

 distinctly arcuate ; disk very convex, with distant, unimpressed rows of small, 

 moderately close-set punctures which are distincly traceable throughout the 

 width and continuing nearly to the apex ; intervals sparsely and more finely 

 punctate, the punctures confused near the siiture but tending to a uniseriate 

 arrangement thence to the sides. Abdomen polished, finely, sparsely punctate, 

 coarsely so near the sides. Length 4.8 mm. ; width 2.1 mm. 



New Mexico (Fort Wingate). Dr. Shufeldt. 



This small species is allied to acutus, but differs in its much 

 shorter more transverse prothorax and distinct elytral series, also 

 in its smaller head and slighter coarser punctuation. 



E. acutus Horn. — Trans. Am. Phil. Soc, XIV, p. 270. — Oblong-oval, 

 more or less inflated behind, strongly convex, polished, the elytra becoming 

 gradually dull toward apex, black, the legs dark rufous. Head moderate, 

 rather convex, finely, very densely punctate ; apex broadly but distinctly 

 arcuate ; eyes very small ; antennae robust and short. Prothorax about three- 

 fourths wider than long, the apex fully four-fifths as wide as the base, just 

 visibly incurvate in circular arc, almost truncate, the angles right and slightly 

 blunt; base truncate, the angles small, right, not at all rounded and distinctly 

 prominent ; sides almost evenly and rather strongly arcuate, abruptly and 

 distinctly sinuate for a short distance before the base ; disk finely but deeply 

 and distinctly punctate, the punctures generally separated by fully twice their 

 own widths but becoming gradually very dense, almost contiguous, although 

 not confluent, toward the sides. Elytra a little less than three times as long 

 as the prothorax and, behind the middle, quite distinctly wider, broadly ogival 

 at apex ; sides distinctly arcuate ; disk finely, rather sparsely and irregularly 

 punctate, with very imperfectly defined, distant, unimpressed series of slightly 

 larger punctures only toward the sides and especially near the base. Abdomen 

 finely, sparsely punctate, as usual much more coarsely and generally more 

 densely so near the sides. Lef/s moderate, the posterior tarsi very distinctly 

 shorter than the tibiae. Length 4.2-4.8 mm. ; width 2.0-2.2 mm.
