REVISION OF ELEODTINI BLAISDELL. 91 



dorsuni, laterally confused and not submuricate ; punctures of both 

 series fine and equal in size. 



Diagnostic characters. — Differs from both qucidricolUs and its race 

 anthracina by the salient type characters. In both sexes the form is 

 smaller and less stout and the female is decidedly less elongate and 

 more robustly ovate. The punctuation is noticeably finer in all the 

 specimens that I have seen, the epistoma is more sparsely and finely 

 punctate, the punctures being not at all confluent. A striking feature 

 in the sculpturing is the very smooth integuments. 



The large anterior tibial spurs separate it from all the constituents 

 of the Carbonaria section. 



Mr. Blanchard, after careful comparisons made with the LeConte 

 material, writes : " I do not recognize this as belonging to any of the 

 named forms; it is nearest to quadricollisy 



The prosternum is more often decidedly mucronate, although not 

 strongly produced. Otherwise as in qKndricoUis. 



ELEODES CUNEATICOLLIS Casey. 



Eleodcfi cunrnticolli.s Casey, Annals N. Y. Acad. Sci., V. Nov. 1890, p. 397. 



Oblong-ovate to ovate, elongate, rather shining; elytra coarsely 

 rugulose. 



Head twice as wide as long, feebly convex or flattened between the 

 eyes, coarsely and strongly, irregularly and more or less confluently 

 punctate, punctures finer on the vertex. Antenna' moderate in length 

 and somewhat stout, scarcely compressed and not dilated, third joint 

 fully as long as the next two combined, the fourth but slightly longer 

 than the fifth, the latter, sixth, seventh, and eighth subequal, ninth 

 suborbicular, tenth transverse, eleventh short ovate. 



Pronotnm widest at the junction of the anterior and middle thirds, 

 one-third to two-fifths wider than long; dixc broadly and moderately 

 convex, more or less declivous laterally and at the apical angles, rather 

 sparsely, coarsely, and deeply punctate, the punctures about tw^ice as 

 large and distinct as those of hxineraJis^ frequently more or less rugu- 

 lose at the sides; apex truncate or broadly and feebly emarginate in 

 circular arc, very finely and more or less obsoletely beaded ; sides 

 strongly arcuate anteriorly, conspicuously convergent and almost 

 straight in basal half, viewed vertically from above, or more broadly 

 arcuate in anterior three-fourths, thence convergent and more or less 

 sinuate to the base, as viewed obliquely from the side, finely beaded ; 

 base truncate to slightly rounded and finely margined, about equal to 

 the length and one-tenth to one-fifth wider than the apex ; apical 

 angles obtuse and more or less narrowly rounded ; basal angles obtuse.
