intervals unevenly, finely, feebly and sparsely punctate, the punctures funn- 

 ing moderately even single series only in the lateral intervals. Abdomen finely, 

 feebly punctate, the punctures sparse but much denser and more rugulose 

 near the sides. Legs very slender, the posterior tarsi much shorter than the 

 tibia?. Length 6.8 mm. ; width 2.6 mm. 



Arizona. 



The metasternum is quite perceptibly longer than the first ventral 

 segment and is rather densely but not very coarsely punctate, the 

 episternum densely punctured. This species is allied to longulus, 

 but differs considerably in the longer prothorax, widest at or near 

 the base and with the sides feebly arcuate, in the duller, more scab- 

 rous and more finely punctate elytra, with confusedly punctate 

 intervals, in its shorter, broader head, with distinctly larger eyes, 

 and in its paler, apparently thinner and more coriaceous integu- 

 ments, being allied in this character more nearly to texanus. 

 Although the punctuation toward the sides of the pronotum is 

 very confluent and scabrous, it does not form the long, even and 

 unbroken rugae which are so characteristic of longulus. 



E. piceilS n. sp. — Oblong, rather robust and convex, parallel, piceous- 

 black ; legs and under surface paler, rufo-piceous ; integuments feebly aluta- 

 ceons. Head moderately transverse, rather finely, not very densely, rugulosely 

 punctate, the punctures of the epistoma much denser, deeper, rounded and 

 not rugulose ; apex broadly, feebly, angularly emarginate at the extremities 

 of the epistomal suture ; apex subtruncate ; eyes rather large, but just per- 

 ceptibly more prominent than the sides of the head ; antennae rather long, 

 moderately slender, the eighth joint much longer than wide. Prothorax short, 

 nearly twice as wide as long, the apex very feeble emarginate and but slightly 

 more than three-fourths as wide as the base, the latter transverse, broadly 

 and very distinctly sinuate at «ach side of the median lobe ; basal angles 

 slightly obtuse, the apical right, both without trace of rounding ; sides evenly 

 and rather strongly arcuate, the disk widest at about basal third, rather finely 

 and sparsely punctate, the punctures gradually dense and semi-confluent 

 toward the sides, the latter with a very fine acute marginal bead. Elytra 

 three and three-fourths times as long as the prothorax and very slightly 

 wider, the sides very feebly, evenly arcuate throughout, broadly ogival at 

 apex ; disk with unimpressed rows of rather small, rounded, shallow punc- 

 tures which are separated by about twice their own diameters, not much larger 

 toward the humeri, the series disappearing in confused punctures before attain- 

 ing the apex ; intervals with moderately even single rows of extremely small, 

 widely distant punctures. Abdomen extremely finely, sparsely punctate, the 

 punctures becoming quite coarse and denser near the sides. Legs moderate in 

 length, the posterior tarsi distinctly shorter than the tibiae. Length 5.7 mm. ; 

 width 2.4 mm.
