head, showing that connate tarsal claws are of even less taxonomic 

 significance here than in some parts of the Barini. 



E. monticola. — Somewhat stout, convex, black, shining ; abdomen 

 subrufescent towai'd base ; legs dark rufous ; antennae rufo-piceous toward 

 base ; punctuation fine and very dense, a little coarser on the elytra, sparser 

 on the abdomen, fine and not extremely dense on the head ; pubescence rather 

 long, dense and conspicuous, sparser on the abdomen, where it is however 

 closer than in the preceding species. Head rather longer than wide, the neck 

 one-third of tlie width, rather wider than the prothorax, convex ; eyes very 

 distant from the base, well developed ; antennae extending to the middle of 

 the elytra, slender, feebly incrassate, the first three joints elongate, subequal 

 in length, tenth scarcely visibly wider than long. Prothorax fully as long as 

 wide, widest at two-fifths from the apex, the sides there strongly rounded, 

 rapidly convergent to the neck, and rather strongly convergent and nearly 

 straight to the base, the latter feebly arcuate and distinctly more than twice 

 as wide as the apex ; disk strongly convex, with a rather strong subquadrate 

 impression in the middle before the base. Elytra large, quadrate, two-thirds 

 wider and one-third longer than the prothorax ; sides parallel and straiglit 

 except very near the apex ; humeri veiy widely exposed ; disk strongly im- 

 pressed on the suture behind the scutellum. Abdomen much shorter tlian the 

 anterior parts, at base four-fifths as wide as the elytra, and, at the apex of 

 the third segment, fully as wide as the latter, coarsely, densely punctate in 

 the three basal impressions as usual. Legs long, slender ; tarsi and claws 

 normal, the latter long, slender, feebly arcuate and moderately divergent. 

 Length 3.25 mm. ; width 0.8 mm. 



Colorado. 



Readily distinguishable from the preceding species by the broader, 

 less narrowed abdomen, which is however only a difference of 

 degree ; in generic structure it agrees perfectly with the others. A 

 single male. 



K. lativentris. — Broader, black throughout ; antennae scarcely piceous 

 toward base ; legs dark rufo-piceous, the tarsi paler ; integuments polished, 

 rather sparsely but strongly punctate, the punctures of the entire upper sur- 

 face of the head, and of the pronotum toward the median line, coarser, very 

 deep, dense and perforate, on the abdomen fine and sparse excej^t in the im- 

 pressions ; pubescence ratlier sparse but distinct, still sparser on the abdomen. 

 Head rather longer than wide with the neck one-third as wide, rather wider 

 than the prothorax ; eyes moderate, before the middle as usual ; antennae 

 extending to about basal third of the elytra, incrassate toward apex, first 

 three joints elongate, subequal in length, tenth quite distinctly wider than 

 long. Prothorax about as long as wide, formed as in the preceding species, 

 the sides broadly sinuate as well as convergent in basal three-fifths. Elytra 

 not quite as long as wide, two-thirds wider and about one-fourtli longer than 

 the prothorax, the sides parallel and feebly arcuate ; humeri widely exposed;
