134 AMERICAN COLEOPTERA 



Two examples only have been seen, that from the former locality 

 being the type which Mr. Belon has most kindly sent me for exami- 

 nation. It is clearly distinct from tenuicornis though closely allied. 



K. teililicoruis Lee. — Oval, feebly convex, brown, the apical two-thirds 

 of the elytra often blackish, legs and antenna' rufous or rufotestaceous : head 

 and thorax densely rugosely punctate and opaque, elytra moderately shining. 

 Head with distinct median sulcus, eyes moderately large and prominent, tem- 

 pore short; autennffi slightly passing the middle of the pronotum, proportional 

 as in the preceding species. Prothorax transversely cordate, sides moderately 

 rounded in front, a little sinuate before the hind angles, which are nearly right; 

 median sulcus lightly impressed, the transverse basal impression as usual ; side 

 margins rather broad and slightly reflexed, minutely subcrenulate. Elytra 

 rather broadly oval, strongly margined, impressed near the base, finely punctate- 

 striate. the punctures a little coarser toward the base; intervals nearly flat. 

 Metasternum not punctate, sides distinctly longitudinally rugose, the post-coxa] 

 fovea- large. First ventral with rather fine, longitudinal rug*, which vary some- 

 what in development, and are usually most noticeable behind the coxa?. (PI. IV, 

 figs. 28, 28a). Length 1.6-1.9 mm. 



Hub. — Pacific Coast from Vancouver to So. California ; Nevada ; 

 Arizona (Chiricahua Mts.)-; Colorado (Ouray); Montana (Gallatin 

 Co.); Michigan (Detroit); New York (Otsego Co.) 



The Michigan example, with which the New York specimens are 

 doubtless identical, though I have not made actual comparison, 

 was described by LeConte as latieollis, but the small differences 

 named do not appear to me to be specific. The few eastern speci 

 mens seen are uniformly brown, as is the type of tenuicornis, but 

 the majority of the western specimens have the elytra blackish, ex- 

 cept at base. In the males the tibiae are all finely serrulate within 

 in about the apical three-fourths, and are distinctly mucronate at 

 tip. The same male characters are seen in the European testaeeus, 

 but appear to have been overlooked by the European authors, at 

 least Belon does not refer to it in his monograph. The fact is note- 

 worthy since external sexual marks are present in but few species of 

 Enicmus proper. Testaeeus and tenuicornis are very similar in 

 nearly all respects, but our species may be distinguished by the 

 absence of the oblique impressed lines of the first ventral, which 

 seem to be always present in testaeeus. 



E. nii leal nl iin sp. nov.— Oval, subeonvex, reddish brown, shining, the 

 head and prothorax a little darker and duller because of their dense punctuation. 

 Head without median sulcus; eyes moderately large, tempora short; antennae 

 attaining the hind angles of the pronotum, proportional about as usual. Pro- 

 thorax broad, subcordate, widest at about the middle, base and apex subequal, 

 the sides a little sinuate before the bind angles, which are only very slightly
