traces at base which appear to be independent of the oblique humeral, the 

 latter distinct; dorsals strong, finely punctate within, entire; sutnral obso- 

 lescent at base. Fropi/gldiwn finely but strongly, rather closely, the pygidiiim 

 more sparsely but equally distinctly punctate, the punctures intermixed with 

 others which are minute. Prosternum strongly, remotely bistriate ; meso- 

 sternum broadly, feebly sinuato-truncate ; marginal stria entire. Length 

 2.3—2.5 mm. ; width 1.2-1.3 mm. 



New Mexico (Las Vegas). 



Resembles planuias, but reraarkablv distinct by reason of the 

 characters stated in the table. It is allied also to lovgvlus, and 

 there are probably several other species having the clypeus simi- 

 lary tuberculate in the male. Three specimens. 



In this species the marginal stria is the ninth, and is represented 

 only by a row of distant punctures in Hister ; the two or three 

 remote and evanescent punctures on the convex flanks here repre- 

 sent the outer subhumeral, and the inner subhumeral evidently at- 

 tains the basal margin irrespective of the oblique inner humeral. 



E. sulltropicus. — Broadly oval, strongly convex, highly polished, black 

 throughout ; antennal club very pale. Head minutely, closely punctate, 

 equally prominent throughout the width between the antennae ; clypeus 

 large, slightly inflexed, more densely punctate, the suture transverse and 

 very fine ; apical margin sliglitly tuberculate at the middle. Prothora.v fully 

 twice as wide as long ; sides strongly convergent, a little more arcuate toward 

 apex ; marginal stria straight, not interrupted at apex ; disk uniformly, finely 

 but strongly and not densely punctate, the punctures coarser at the basal 

 margin, rather broadly so in the middle. Elytra distinctly shorter tlian wide, 

 not quite twice as long as the prothorax, and, near the middle, quite distinctly 

 wider ; sides evenly, distinctly arcuate ; disk very minutely, evenly, sparsely 

 but distinctly punctulate, less strongly than the pronotuni ; inflexed flanks 

 unistriate ; lateral stria entirely inferior, only slightly ascendent toward base ; 

 outer subhumeral wanting, the inner represented only by a short trace near 

 the middle ; oblique humeral fine but long ; dorsal striae not very coarse, 

 abrupt, not distinctly punctate ; first three entire ; fourth not quite attaining 

 the base ; fifth and sutural abruptly abbreviated, the sutural also abbreviated 

 before the apex. Propygidium finely but strongly, not densely punctate, the 

 pygidium large, flat, with the punctures fine deep and rather close. Pro- 

 sternum with the deflexed lobe very short, wide, strongly and finely margined 

 at apex, the intercoxal striae distant, becoming subparallel and slightly abbre- 

 viated anteriorly ; mesosternum with a broad and shallow emargination, the 

 apical stria broadly interrupted. Intersternal sutnre widely double, the 

 anterior line broadly subaugulate throughout the width, distinct, evenly 

 crenulate, extending anteriorly two-thirds to the emargination ; posterior line 

 almost obliterated. Length 2,3 mm. ; width 1.6 mm.
