Nebraska — Cab. LeConte ; Colorado. 



The series of punctures on the elytra are less distinct than in any 

 other species of this group, and on the inner half are only traceable 

 under careful observation and with the exercise of a considerable, 

 amount of imagination. The prothorax is slightly wider just be- 

 hind the middle than at base. 



. EPITRAGUS Latr. 



The species of Epitragus are, in general, strongly isolated among 

 themselves, in fact more conspicuously so than in any other Tene- 

 brionide genus which I can recall to mind at present; the trans- 

 verse prosternal groove is well developed in all the representatives 

 which I have seen. The following species is not closely related to 

 any other : — 



E. fusiform is n. sp. — Elongate, fusiform, rather slender, moderately 

 convex, piceous-black with an aeneous tinge, polished between the extremely 

 dense punctures. Head fully as long as wide, finely, deeply, very densely 

 punctate ; supra-orbital fold completely obsolete above the eye, feebly evident 

 for a short distance before it ; antennas rather long, but strongly and gradually 

 clavate, the third joint long, tenth a little wider than long. Prothorax about 

 one-fifth wider than long, the apex three-fourths as wide as the base, trans- 

 versely trunoate between the strongly advanced and acute apical angles ; base 

 broadly, strongly lobed in the middle ; basal angles right, not at all rounded, 

 sometimes feebly prominent ; sides extremely feebly, nearly evenly arcuate ; 

 disk finely but deeply and very densely punctate, the punctures finer and in 

 close contact near the sides, distinctly separated toward the middle where there 

 is a narrow impunctate median line. Elytra at base not distinctly wider than 

 the prothorax, rather less than three times as long as the latter and, near the 

 middle, two-fifths wider, finely, irregularly, evenly and extremely densely 

 punctate throughout, the punctures shallow, each bearing an excessively 

 minute robust acuminate seta which does not project much beyond the limit 

 of the puncture ; apex acutely ogival. Abdomen finely, very densely punctate, 

 and with short fine inconspicuous pubescence. Length 10.5-11.2 mm. ; width 

 4.7 mm. 



Arizona. 



The mesosternum is deeply and acutely excavated as usual. In 

 tomeiitosus, however, the mesosternum is not even distinctly im- 

 pressed and that species will therefore have to be placed in another 

 genus for which I would suggest the name Epitragodes. 



The only species with which fusiformis can be compared is 

 plumbeus, but it differs very greatly from that species in its promi-
