In this genus the sexual characters are feebler than in Coscinop- 

 iera. The fovea in the last ventral of the female is scarcely evident. 

 In a male of piisilla the mandibles are distinctly angulate externally. 



E. L.eCoiitei Crotch, Proc. Acad. 1873, p. 28: scapularis J Lee. olim. — Form 

 moderately elongate, piceous black, shinino;; elytra with a humeral red spot, 

 somewhat variable in size. Head and thorax moderately densely clothed with 

 ashy-white pubescence ; head densely and rather coarsely punctured, thorax as 

 long as wide, or slightly longer, relatively coarsely punctured, closely on the 

 disc, more densely at the sides, a smooth median line; scutellum with few coarse 

 punctures. Elytra slightly narrowed posteriorly, subhumeral lobe rather large, 

 the striie of punctures coarse, deep and closely placed, intervals feebly convex, 

 scntellar stria much confused. Body beneath densely punctured, cinereo-pu- 

 bescent. Length .10 — .2:2 inch.; 2.5 — 5.5 mm. 



In this species the humeral red spot has a constant form in the 

 numeixnis specimens examined. It begins under the humeral um- 

 bone passing around that leaving it black, extends inwards to about 

 the fourth stria and about one-third the length of the elytra. The 

 posterior edge is oblique. 



As synonyms of this species I unhesitatingly place longicollis and 

 parvula Jacoby (Biol. Cent. Am. vi, pt. 1, suppl. pp. 78, 79, pi. 

 xxxvii, figs. 5, 6). Exactly similar specimens from the same source 

 are before me in much greater number than seen by Mr. Jacoby. 

 That author seems to have misunderstood Crotch's expression " thorax 

 coarsely and strongly punctate," which is undoubtedly exact rela- 

 tively to any others he had before him. 



Occurs in Texas and Arizona. 



K. pusillsi. n. sp. — Subcylindrical, a little more robust than LeContei. piceous 

 black, sinning, elytra with a quadrate red, humeral spot. Head closely and 

 i-ather coarsely punctate, ciiiereo pube.scent, labruui yellow in the male, darker 

 in female. Thorax broader than long, coar.sely iuid closely punctate, cinereo- 

 pubesceiit, a smooth median line; scutellum numerously i)unctate. Elytra 

 scarcely narrowed behind, subhumeral lobe feeble, the humeral red spot sub- 

 nuadrate, extending inward to the fifth stria and nearly squarely truncate poste- 

 riorly, elytral striae composed of coarse, deep and closely placeil punctures, which 

 are wider than the intervals. Body beneath densely punctured and i>ubescent. 

 Length .16 inch. ; 4 mm. 



The males have the m;indibles distinctly angulate externally. 



This species is closely related to LeContei, but has a much broader 

 thorax, at least a third wider than long, while in that species the 

 thorax is as long, or even a little longer than wide at middle. The 

 humeral spot is here quadrate and covers the unibone, and the sub- 

 humeral lobe is feeble.
