44 TIIOS. L. CASEY. 



E. scillptile 11. sp. — Form slender, nearly semi-cylindrical, sides 

 parallel ; erect setae of elytra excessively short and sparse, scarcely visible ; 

 Color of upper surface piceous-black, beneath very dark piceous-brown, nearly 

 black, with a tinge of rufous ; legs and antennae just perceptibly paler. 

 Head moderately convex, transversely and feebly impressed in front of the 

 eyes ; anterior margin transverse, sides rounded ; punctures somewhat 

 deeply impressed and scattered in the middle, closer elsewhere; supra- 

 orbital ridges distinct ; labrum squarely truncate in front, sides widely 

 divergent posteriorly and nearly straight, anterior angles well developed ; 

 antennae moderate, third joint much longer than the fourth. Prothorax 

 three-fourths wider than long ; sides strongly and evenly arcuate ; apex 

 distinctly shorter than the base ; apical and basal angles very acute and 

 prominent ; apex feebly emarginate in the middle, nearly throughout its 

 width, base distinctly trisinuate, nearly transverse ; disk very convex, dis- 

 tinctly margined anteriorly and posteriorly ; sides narrowly retlexed, edges 

 acute ; punctures small and impressed in the middle, larger, shallow, oval, 

 somewhat confluent, and scabrous at the sides. Scutellum minute and trans- 

 verso, angulate behind. Elytra at base slightly wider than the contiguous 

 pronotum ; sides parallel and very feebly arcuate for two-thirds the length 

 posteriorly ; disk very convex, acutely rounded behind ; punctures arranged 

 in rows, rather distant, moderately large, very shallow, variolate, round ; 

 there are also several elongated, striae-like impressions near the suture, and 

 the surface is minutely, irregularly, and very distinctly creased, minutely 

 undulated, and very minutely granulated ; sculpture more rough near the 

 sides, which are very feebly reflexed. Under surface of the abdomen finely 

 and nearly evenly punctate ; prosternum more coarsely punctate. First 

 joint of the posterior tarsi scarcely longer than the next two together, dis- 

 tinctly shorter than the last. Length 6.0 mm.; width 2.3 mm. 



Arizona (Morrison). 



Tlie sculpture of tlie elytra is very composite and strongly developed. 

 The nientum.is emarginate at apex through a length equal to about 

 one-tiiird its width at base ; emargination most strongly rounded at 

 the bottom, anterior angles well rounded ; exposed surface strongly 

 puncfate and transversely rugulose. The prothorax is much more 

 strongly arcuate at the sides and more convex than in pupayomini, 

 which this species somewhat resembles ; it is more slender than that 

 species. 



E. flllbillin n. sp. — Form rather robust, sides parallel ; moderately con- 

 vex ; lii'.ul anil prothorax glabrous, elytra having very sparse, robust, erect 

 setae, which are more plentiful at the sides ; color piceous-black above and 

 beneath, legs rufo-piceous, antennae and palpi same. Head much broader 

 tiian long ; interocular surface moderately convex, moderately declivous in 

 front of the eyes, transversely and feebly ridged just behind the anterior 

 margin ; the latter broadly truncate, rounded at the sides ; punctures round, 

 varying in size, evenly distributed, and distant their own widths ; between 

 the eyes, near the anterior margin, the sculpture becomes very confluent and
