132 AMERICAN COLEOPTERA. 



to the fourth, following joints gradually narrower, the eleventh only 

 slightly longer than the tenth. Head flattened in front and feebly 

 broadly concave, the apical margin not or but little reflexed, densely 

 punctate. Prothorax a little longer than wide, sides feebly arcuate, 

 a little narrowed in front, not sinuate posteriorly, the hind angle not 

 produced, rectangular; surface densely, nearly evenly, not coarsely 

 punctate, median line vaguely impressed, hind angles not carinate. 

 Elytra very little wider than the prothorax and two and one-half times 

 as long as wide, finely striate, intervals nearly flat, closely punctate. 

 Beneath rather densely not coarsely punctate, the presternum some- 

 what less closely punctate. First joint of hind tarsus not quite as long 

 as the three following ; tarsal joints without lobes. Length, 8.5-10.5 

 mm. ; width, 2.3-2.9 mm. 



Placer County, California (G. R. Pilate). 



The pubescence is pale throughout, rather closely recum- 

 bent with sparsely dispersed longer more erect hairs both 

 above and beneath, most noticeable on the pronotum, where, 

 however, they are only evident when viewed in profile. This 

 peculiarity of the pubescence is observable in a few other 

 species of Athous, notably in discors and agriotoides, the latter 

 of which very closely resembles the present species. In 

 agriotoides the pubescence is longer throughout, the pro- 

 thorax more coarsely punctate, the second antennal joint 

 only half the length of the third, the latter nearly as long as 

 the fourth, and the third tarsal joint is conspicuously lobed. 



CORYMBITES Lat. 

 0. linearis n. sp. 



Very narrow, rather feebly shining, sparsely pubescent, prothorax 

 rufotestaceous with the side margin and a broad median longitudinal 

 vitta fuscous, elytra yellow with side margin and broad sutural stripe 

 dark brown ; beneath rufotestaceous, the sterna more or less com- 

 pletely infuscate ; presternum yellow in front, the tip of the lobe dark. 

 Antennae brown, slender, half as long as the body, the seventh joint 

 reaching the hind angles of the prothorax (cf), second joint short, 

 nearly as wide as long and scarcely half as long as the third, the latter 

 elongate triangular, a little more than twice as long as wide, the apical 

 angle obtuse ; fourth joint slightly longer than the third, the follow- 

 ing joints becoming gradually longer, 6-11 parallel, the tenth at least 

 four times as long as wide. Head densely coarsely punctate and 

 feebly concave. Prothorax much longer than wide, apex not wider 

 than the head, sides straight and gradually divergent to base angles, 

 a faint sinuation before the latter, which are, however, scarcely diver-
