350 Coleopterological Notices. 



Color dark castaneous ; body very convex ; punctures of the pronotum 



rather coarse and very dense fallax 



Sides of the prothorax very strongly, evenly rounded in a circular arc 

 having its centre near lateral third of the pronotum. 

 Castaneous, dull and alutaceous, the pronotum finely and extremely 



densely punctate throughout tllOI'aciCUS 



Black, highly polished ; pronotum rather coarsely punctate and distinctly 



more sparsely so toward the middle niticlllS 



Basal angles of the prothorax acute and prominent, the sides before them 

 being distinctly sinuate for a short distance. 

 Elytral series distinct throughout the width. 



Head large ; integuments very dull crassicomis 



Head small ; prothorax very short ; integuments polished. 



coarcticollis 



Elytral series confused on the upper portion of the disk and with scam-ly 



a trace of serial arrangement acutUS 



E. texaniis Lee. — New Spec. Col., 1866, p. 108. — Oblong-oval, moderately 

 robust, somewhat depresseil, pale brownish-testaceous throughout ; integu- 

 ments rather thin, polished. Ilvad rather small and transverse, not over one- 

 half as wide as the prothorax, somewhat coarsely and densely punctate ; eyes 

 large and slightly more prominent than the sides ; epistoma truncate, obtusely 

 and angularly lobed in the middle, the lobe distinct and slightly deflexed ; 

 antenna! long and slender. Prothmi.r fully three-fourths wider than long, the 

 apex scarcely more than two-thirds as wide as the base, broadly subtruncate 

 between the acute and strongly, anteriorly prominent angles ; base transverse, 

 broadly, strongly bisinuate, the basal angles right, not at all rounded but not 

 prominent, sides very evenly and rather strongly arcuate throughout ; disk 

 about as wide at base as behind the middle, rather coarsely and sparsely punc- 

 tate, the ]>unctnres unevenly distributed and distant by from once to twice their 

 own diameters, but rapidly becoming very dense though scarcely conlluent 

 near the sides, the latter finely, acutely beaded. Elytra just visibly wider 

 than the prothorax and more than three times as long, parallel, the apex 

 ogival ; disk with distant, distinctly impressed strire which continue to the 

 apex and are coarsely, rather strongly and approximately punctate, the punc- 

 tures variolate as usual ; intervals flat, each wi'.h a more or less regular single 

 line of much smaller punctures which are confused toward the suture. Trans- 

 verse nietasternal groove \eTy deep. Lejjs very slemler, the posterior tarsi 

 slightly but distinctly shorter than the tibia3. Length (J. 6 mm. ; width 2.0 nun. 



Texas. Cab. LeConte. 



The epistoma is evenly rouiided hiterally at the sutures, and not 

 in the least enmrginate ; the hind wings are very well developed. 



This ."species is quite distintit and cannot easily lie confounded 

 witli any other, the feebly iHiHlnct'd angnlate lobe of the epistoma
