130 AMERICAN COLEOPTERA. 



'Phis form in common with typical aterrimm and brevicomis pos- 

 sesses a character which appears to have escaped notice by previous 

 writers. The first joint of all the tarsi hears beneath, at the apex, 

 a short acute spiniform process, which varies a little in develop 

 raent. This variation may possibly be dependent on the sex of the 

 individual, though I have not been able to assume myself that this 

 is the case. The middle coxae are rather more widely separated 

 than in any other of our species. 



E. <1 up lira Mis Lee. — "Moderately elongate, blackish piceous, opaque. 



Prothorax one-half wider thau long, narrowed behind, sides finely serrate, 

 rounded in front, oblique behind, hind angles obtuse; disk feebly impressed in 

 front of middle, and with a shallow transverse impression behind the middle. 

 Elytra one-third wider than the prothorax, elongate-oval, stria* composed of 

 punctures, not regularly arranged, and approximated by pairs; the sutural and 

 two outer ones are slightly impressed near the tip. Legs rufopiceous." Length 

 L.9 mm. 



Hab. — Illinois; Michigan (Detroit). 



The above is LeConte's description. I have seen only the two 

 type specimens in the LeConte cabinet. It is separable from all 

 others by the approximation of the elytra! strise by pairs. 



E. iii:i<'iil:il us Lee. — Less elongate than aterrimtts, the elytra more oval; 

 black, opaque, elytra testaceous, irregularly maculate with black. Head and 

 thorax densely, finely punctate, the former strongly channeled, the hitter trans- 

 versely cordate, posteriorly deeply transversely impressed and with a deep longi- 

 tudinal discal fovea anteriorly. Elytra elongate-oval, finely striate, the strise 

 finely punctate. Metastemum finely, moderately closely punctate laterally, 

 less closely at the middle ; first ventral segment still more finely punctate, the 

 following segments indistinctly punctulate. Length 1.9-2.1 mm. 



Hub. — Virginia; Ohio; Michigan. 



The short description above is quite sufficient for this species, 

 which is, by coloration, the most easily recognized Lathridiid in our 

 fauna, It does not appear to be at all common, and I have seen 

 altogether not more than a dozen examples. 



E. crassi|>uiic*atus sp. nov. — Elongate-oval, feebly convex, subopaque, 

 fuscous, the elytra with the humeri and a broad apical area ferruginous, legs 

 Hiid antenna' ferruginous. Head scarcely at all wider than long, densely 

 rugosely punctate; front convex, longitudinally lightly sulfate: eyes small, 

 tempora parallel and nearly as long as the eyes; antennae passing slightly the 

 middle of the prothorax, outer joints of funicle subquadrate, club abruptly 

 formed, its first two joints transverse. Prothorax transversely subquadrate, 

 widest just in front of the middle, sides not strongly rounded, a little sinuate 

 posteriorly, base and apex subequal, surface densely punctate, foveate ante- 

 riorly on the disk, and moderately, deeply, transversely impressed before the
