of the intervals being but slightly smaller and equally widely separated. 

 Abdomen rather strongly and deeply but not very densely punctate throughout. 

 Ze^s normal. Length 6.4 mm. ; width 2.8 mm. 



New Mexico (Santa Fe). Miss M. "W. Greene. 



A robust and very convex species, bearing a deceptive external 

 resemblance to convexus, but easily distinguishable by the charac- 

 ters eriven in the table. 



O' 



E. tlioraciciis n. sp. — Oblong, rather strongly convex, dull and aluta- 

 ceous, dark piceo-castaneous throughout, smooth. Head moderate, transverse, 

 broadly, rather strongly arcuate at apex, finely, deeply, very densely punc- 

 tate, the eyes small and antennse robust. Prothorax about four-fifths wider 

 than long, the apex slightly narrower than the base, almost transversely 

 truncate, being just perceptibly incurvate, the angles very slightly obtuse 

 and rather broadly rounded ; base truncate, the basal angles very obtuse but 

 not rounded and not in the least prominent ; sides parallel, very strongly, 

 evenly rounded in circular arc from base to apex ; disk much wider in the 

 middle than at base, finely, deeply and very densely punctate, the punctures 

 equally dense throughout the width, the lateral bead extremely fine. Eli/tra 

 equal in width to the prothorax and three times as long, the sides parallel 

 and just perceptibly arcuate, the apex rather obtuse; disk with very feebly 

 impressed striie of small but deep and very approximate punctures, the series 

 not attaining the extreme apex ; intervals flat, very finely, rather sparsely 

 and irregularly punctate. Abdomen rather coarsely and densely punctate 

 throughout the width. Legs moderate, the posterior tarsi much shorter than 

 the tibire. Lengtli 6.(5 mm. ; width 2.6 mm. 



California (San Gorgonio Pass?) 



The nietasternum is just visibly shorter than the first ventral 

 segment, rather coarsely, deeply, very densely and conspicuously 

 jiunctate, the usual transverse groove indicated by a very broadly, 

 feebly impressed series of smaller and unevenly placed punctures. 



This is one of the most distinct species of this section of the 

 genus, distinguishable at once by the very strongly arcuate sides 

 and obtuse basal angles of the prothorax and finely, evenly punc- 

 tured disk ; the very feeble impression of the elytral series may 

 possibly be an accidental characteristic of the unique example, but at 

 all events the series themselves are much more distinct than usual. 



E. nitidllS n. sp. — Elongate-ovoidal, rather strongly convex, highly 

 polished, l»lack, the antennae black; legs very dark rnfo-piceons. Iliad 

 nearly two-thirds as wide as the prothorax, rather transverse, broadly arcuate 

 throughout at apex, rather convex, finely, deeply and densely punctate; eyes 

 small, the folds short but very distinct ; antennse short and robust, Prothorax 

 short, five-sixths wider than long, the apex slightly narrower than the base,
