Colorado, and New Mexico. 
Genus Trichalophus Lee. 
Trichalophus stefanssoni, n. sp. 
Oblong-oval, black, thickly clothed above and beneath with short, white, 
decumbent hairs, sometimes condensed into vaguely defined spots on the 
elytra and an oblique line at each side of disc of thorax. Beak finely carinate, 
slightly dilated at apex, antennal groove deep, almost reaching the eye; scape 
of antennae almost reaching the eye, funicle seven-jointed, first two joints each 
longer than the succeeding bead-like joints, club three-jointed, oval, pointed, 
annulated. Eyes oval, transverse, finely granulated. Head slightly protuberant 
between and above the eyes. Thorax slightly longer than wide, slightly con- 
stricted and narrower in front; surface uneven, a complete median carina with 
a minute polished tubercle each side thereof being the most conspicuous inter- 
ruptions of the surface. Elytra oval, convex, with feeble numeral angles, 
surface irregularly interrupted and tending to iform rows of small tubercular 
elevations. The surface is very minutely punctulate between the elevations, 
visible only by removing the hairs. Front coxae contiguous, prominent; middle 
coxae separated by less than half their width; also prominent; hind coxae widely 
separated, not prominent first again longer, oval at tip. Femora slightly 
incrassate, tibiae excavated at apex, with spinulose fringe and a conspicuous 
spine; tarsi broad, pubescent beneath, third joint divided, claws simple. Re- 
sembles in many respects Trichalophus didynius Leconte from Vancouver, 
British Columbia and Colorado, but differs in the shorter antennae, the carination 
of the beak, the size and obscure maculation. 
Length, including beak, 10-12 mm.; width, at middle of the elytra, 3-5- 
5-0 mm.
