Coleopterological Notices. 36 "7 



prothorax being right, not rounded, not everted and not prominent, 

 but in the absence of a typical representative of the latter species I 

 am unable to describe it ; the specimens were collected at El Paso, 

 Texas. 



C. pallidum n. sp. — Moderately convex, pale luteo-testaceons through- 

 out, rather shining, subglabrous, the widely scattered seta? slightly evident 

 behind. Head finely, rather feebly but densely punctate ; eyes large, supra- 

 orbital fold fine, short ; antennas long and slender. Prothorax not more than 

 one-third wider than the head, two-fifths wider than long ; apex about as wide 

 as the base, very feebly arcuate between the advanced, acute and prominent 

 angles ; base transverse, broadly bisinuate, the basal angles slightly acute and 

 prominent ; sides strongly, subangularly arcuate at or just before the middle, 

 thence convergent and straight or broadly, extremely feebly sinuate to base 

 and apex ; disk rather coarsely but variolately punctate, the punctures very 

 densely crowded laterally, very slightly separated toward the middle, with a 

 broad, subimpunctste and irregular median line. Elytra across the humeri 

 almost one-fourth wider than the pronotal disk, behind the middle from one- 

 third to one-half wider than the latter, nearly four times as long ; disk rather 

 finely, subserially punctate ; humeri rounded. Length 6.4-7.0 mm. ; width 

 2.6-3.0 mm. 



Texas (El Paso). 



In addition to the characters given in the table, this species 

 differs from abnorme in its larger size, more robust form, paler 

 color and shorter, almost squarely truncate middle lobe of the 

 epistoma ; in abnorme the middle lobe is evenly, almost semi-circu- 

 larly rounded and is much longer. The series consists of live 

 specimens and does not indicate any notable variation either in 

 color or size. 



ZOPI1ERUS Lap. 



Z. illdliratllS n. sp. — Robust and convex, deep black throughout, the 

 pronotum dull and with a strong alutaceo-sericeous lustre ; elytra more shin- 

 ing. Head moderate, sparsely, not very coarsely punctate ; antenna; very 

 short and robust. Prothorax fully as long as wide, widest and with the sides 

 very broadly subangulate at two-fifths the length from the apex, the latter 

 broadly emarginate, subtruncate between the advanced and narrowly rounded 

 angles ; base equally wide, very feebly arcuate ; sides convergent from anterior 

 two-fifths to the base and broadly obtusely subangulate at basal third ; disk 

 convex, coarsely but sparsely punctate, the punctures strongly muricate. 

 Elytra about two-thirds longer than the prothorax and, in the middle, nearly 

 one-fourth wider, evenly oval, convex, feebly emarginate at base; disk strongly 

 but rather finely, densely and confusedly tuberculate, the two apical tuber- 

 cles very strong, the channels very deep but rather short. Abdomen coarsely, 

 sparsely, punctate. Length 16.5 mm. ; width 7.0 mm.
