1. liV^ issillllis n. sp. — Robust, snbparallel, rather strongly convex, 

 smooth and liuely alutaceous, the pronotum ratlier more shining than the 

 elytra. Ihad rather longer than wide, somewhat coarsely but sjKirsely punc- 

 tate ; antenn.'e very robust. Prothorajc alnnit one-h.nlf wider than long, tho 

 apex truncate and very distinctly narrower than the base, the latter trans- 

 verse and broadly, feebly bisinuate ; ba.'sal angles acute and prominent ; sides 

 parallel and strongly arcuate in apical two-thirds, then strongly iMUvergent 

 and sinuate to the base, very oo."u-sely and nnevenly crenulate ; disk rather 

 strongly convex, declivous towanl the sides which are very narrowly retlexetl. 

 very sparsely and minutely punctate, more coarsely but scarcely more densely 

 so very near the sides. Ui/trti just visibly wider Whind, two thinis longer 

 than wide, gradually narroMetl and i>ointetl through apical third, about three 

 and oiu^half times longer and nearly one-third wider than the protliorax ; 

 humeri rv^unded ; disk abrtiptly declivous from a short distance behind the 

 kise to the basal margin, very smooth but alutaceous, the stri.«p feebly indica- 

 teil by very fine and nearly ol>solete longitudinal creases. Length 23.5 mm. ; 

 width 9.3 mm.

This is one of the larjrest species known to me, and is very dis- 

 tinct from lewi\<i iu its much more robust form, more transverse 

 prothorax. declivous base of the elytra and unimpressed stri:v. 



The two species /crr^^■^v'»J^<^" and lewif-i are further distiniiuished 

 from scrratus and sublavis by the somewliat longer head, less 

 widely flattened and exi>lanate sides of the pronotum and truncate 

 ap*^x. the apex of the protliorax beiusj; relatively wider and broadly, 

 feebly sinuate in the latter of the two Lrroups.

The characters orisrinally employed by LeConte and subsequently 

 followed by Horn in the classification of our genera of Blapstini, 

 do not seem to be sullicientlv concise or decisive to distiui-uish the
