me.liate surface moderately convex ; sai)ra-aiiteiiiial Inberculations small, 

 somewhat prominent, connected by the moderately arcuate frontal ridge; 

 antennae slender, but slightly longer than the head, club large, ninth and 

 tenth joints equal in length, one-half wider than long, the latter one-third 

 wider than the ninth, eleventh somewhat abruptly much wider, evenly 

 conoidal, acuminate, elongated, as long as the four preceding joints together. 

 Prothorax widest slightly in advance of the middle, very slightly wider than 

 the head, and just visibly wider tlian long; sides arcuate anteriorly, nearly 

 straight posteriorly ; apex about one-half as long as the pronotal width, and 

 three-fourths as long as the base, both slightly arcuate; disk strongly con- 

 vex, coarsely granuldse, shining ; having a large, deep, elongated, fusiform, 

 medial canalioulation ; also having at one-third the length from the base a 

 narrow, deep, posteriorly cusped, transverse groove, very slightly dilated at 

 the middle into a fovea, and terminating at the sides in rather large, shallow, 

 spongy-pubescent foveae. Elytra at base distinctly wider than the pro- 

 thorax ; sides distinctly divergent posteriorly and rather strongly arcuate ; 

 disk quadrate, rather convex, shorter than the head and prothorax together, 

 smooth, almost impunctate, shining ; sutural striae strong, close, and arcuate, 

 lateral short and feeble. Abdonien slightly narrower than the elytra ; sides 

 nearly parallel and straight; border rather narrow and slightly inclined; 

 surface rather convex, shining, impunctate; first three segments equal; first 

 two dorsals witii two distant, excessively short, and feeble divergent carinae. 

 Legs rather short and slender. Under surface of the iiead apparently with 

 a few widely scattered sensitive setae anteriorly Length 0.7 mm.

Described from Dr. LeConte's unique type. 



This species greatly resembles dehilis Lee. in everything but color, 

 and differs from it in its smaller size, more robust form, less smooth 

 and polished integuments, and in the shape of the pronotum, which 

 is slightly less narrowed anteriorly tlian in that S[)ecics. The carinae 

 of the dorsal segments are so small and obscure that I am not abso- 

 lutely sure of their existence, because of the somewhat imperfect 

 condition of the type. 



3. E. (lebilis Lee— Proc. Am. Phil. Soc. XVIL 1S7S, p. 386, No. '20.— 

 Form slender. Pubescence sparse, short, cinereous, rather inconspicuous, 

 with much longer, very widely scattered setae upon the abdomen. Color 

 piceous-brown, antennae and legs distinctly paler, elytra slightly darker; 

 integuments highly polished. Head small, slightly wider than long; eyes 

 small, convex, and very prominent ; genae very small, rather acutely 

 rounded, shorter than the eye ; base broadly and feebly sinuate throughout ; 

 interocular surface abruptly and very strongly elevated, moderately convex 

 above, not punctate ; having two small, deeply impress.ed foveae at one-half 

 the length from the posterior angles, mutually slightly more distant than 

 either from the eye, connected by an anteriorly arcuate, parabolic, feebly 

 impressed, and narrow channel, which terminates completely in the foveae; 

 supra-antennal tuberculations small, angulate, and not very prominent,
