146 MEMOIRS ON THE COLEOPTERA 



mm.; width 3.35 mm. Mexico (Colonia Garcia, Sierra Madre Mts., 

 Chihuahua), C. H. T. Townsend. 



This very distinct species could only be compared with unicolor 

 Horn, and from that it differs in the dense elytral punctures, re- 

 latively shorter third antennal joint, sparse punctures toward the 

 base of the prothorax, more elongate elytra and in many other 

 features. 



*Epipocus simplicipes n. sp. Body somewhat 'as in mutilatus in outline 

 and coloration but a little narrower, the elytra conjointly evenly rounded 

 at apex; surface polished, the pubescence fine, not at all dense and rather 

 moderate in length: head barely half as wide as the prothorax, the eyes 

 very prominent; antennae not quite half as long as the body, somewhat 

 slender, with broad club, black, the two basal joints and tip of the eleventh 

 ferruginous, the third joint not quite as long as the next two combined, 

 tenth strongly transverse; prothorax much less than twice as wide as the 

 median length, of the usual form, the sides broadly, subevenly reflexed 

 and more closely punctate; sulci rather narrow, feebly arcuate, extending 

 beyond the middle, with two foveiform impressions near the sulcus, the 

 anterior beyond the end of the latter; surface between the sulci broadly 

 convex, evenly, deeply, rather coarsely and not densely punctate, with a 

 fine impunctate median line; scutellum semicircular, ferruginous, finely, 

 sparsely punctate; elytra rather strongly convex, one-half longer than 

 wide, widest near the middle, at the tumid humeri distinctly wider than 

 the prothorax, colored as in cinctus and mutilatus, the punctures very 

 moderate in size and widely separated, the marginal gutter broad, 

 disappearing completely beneath the elevated humeri; under surface 

 ferruginous, the abdomen in great part black, shining, strongly and closely 

 but not coarsely punctate; tibiae in the male all straight and unmodified, 

 the sixth ventral well exposed, broadly rounded and with its surface 

 somewhat impressed transversely, except at the middle. Length (cf ) 

 7.0 mm.; width 3.5 mm. Mexico (Orizaba). 



The only species with which this can be compared is tibialis, but 

 the tibial characters of the male, described by Gerstacker as per- 

 taining to that species, are completely wanting. The pronotum is 

 ferruginous, with the entire area between the sulci and extending 

 from base to apical fifth deep black. The two fovese obliquely 

 arranged at each side of the middle of the pronotum are bilaterally 

 similar and do not appear to be adventitious. 



EROTYLIM; 



The Languriids occupy a very isolated position among the Ero- 

 tylids, but, though constituting a distinct subfamily, there was little 

 cause to consider them apart from the rest of the family in the
