182 THE CANA.UIA.N ENTOMOLOGIST. 



individual at Hunter's Bay. Alaska, from a cut place on the trunk of a 

 conifer. Two specimens in my cabinet, collected by Rev. Geo. W. 

 Taylor, at Nanaimo, Vancouver Island, are a little more deeply punctured. 



P. hesperus, n. sp. — Oblong, blackish, feebly shining, a faint aeneous 

 tinge, pubescence pale, recumbent, moderately coarse. Head deeply and 

 densely, rather coarsely, punctured, front with a distinct median fovea, 

 around which the punctures are less crowded. Antennae gradually 

 clavate, about reaching the base of the thorax, piceous-red, club blackish; 

 first joint large and heavy, second subglobose, not quite as thick as the 

 first, third more slender than the second but nearly as long, fourth and 

 fifth subequai, a trifle shorter than the third, sixth broader, seventh to 

 tenth wide, subequai in length, eleventh nearly twice as long as the tenth, 

 oval, pointed. Thorax distinctly, finely and rather closely punctured, 

 narrowed anteriorly, the sides not arcuate but slightly sinuate, lateral 

 margin sharp, front and hind angles acute. Scutelluin covered with pale 

 yellowish pubescence. Elytra continuing the outline of the thorax, finely, 

 distinctly and fairly closely punctured and indistinctly sulcate, sides 

 subparallel, tips conjointly rounded. Beneath rufo-piceous, thickly clothed 

 with pale pubescence, which almost conceals the sculpture, especially on 

 the abdomen. Legs piceous, femora paler, all grooved for the reception 

 of the tibijB. Tibiae spinulose externally, front and middle pairs with 

 exterior margin arcuate, hind pair simply broader towards tip. Third 

 tarsal joint lobed beneath. Length, 4 mm. 



Leadville, Colorado, July, taken by myself under stones on a hillside. 

 The front tibiae alone are grooved for the reception of the tarsi. The 

 antennae are much stouter in comparison than those of F. Lecontei. In 

 general appearance this insect approaches P. subcatms, but is at once 

 distinguished by the lack of bristly hairs among the pubescence. From 

 acuminatus it may readily be separated by colour and outline ; oblongus 

 differs in the bright green colour, strongly shining surface and lack of 

 elytral sulcations, while ceneolus should at once be separable by the simple 



tarsi. 



P. subcain/s, Leconte, Coleoptera of Michigan, Proc. Am. Phil. Soc, 

 XVII., 1878, p. 609. Described from Escanaba, Lake Superior. I have 

 it from Bayfield, Wisconsin, on the southern shore of the same lake, and 

 from Leadville, Colorado.
