Q. seriatns n. sp. — Head oval strongly constricted behind, front without 

 punctures, at base of antennse a small puncture, two at the inner margin of 

 each eye, one on the occiput, and one behind the eye. Labrum truncate. 

 Eyes large and prominent. Antennse attaining the middle of the thorax, 

 second joint as long as the third. Thorax longer than wide, narrower in front, 

 sides feebly, base more broadly arcuate, surface smooth and shining, anteriorly 

 on the disc three punctures, laterally a row also of three, marginal punctures 

 small and distant. Scutellum smooth, shining. Elytra a little wider than the 

 thorax, conjointly longer than wide, surface shining and with rows of punc- 

 tures arranged as follows: a scutellar series of three punctures, a row of six 

 or seven beginning at the humeri, an intermediate series of three or four, a 

 marginal series of six or seven exterior to which are a few irregularly placed 

 punctures. Abdomen very sparsely punctate, segments vaguely transversely 

 impressed and with a slight space with greyish hair, beneath more coarsely 

 punctured than above. Femora sparsely punctulate, tibise iinely spinulose 

 externally. Length .24 inch ; 6 mm. 



The sixth ventral of the male is eruarginate, the anterior tarsi 

 feebly dilated. 



The color is black, shining, the elytra aeneous, the antennae are pale 

 rufous. The femora are rufo-testaceous, the tibiae slightly piceous. 



Post coxal process short, translucent. 



One specimen, Vancouver, Crotch. 



Q. puncticeps n. sp. — Head orbicular, strongly constricted behind, two 

 frontal punctures deeply impressed and with numerous punctures above each 

 eye on the vertex and occiput and behind the eyes. Labrum truncate. Eyes 

 large, oval, oblique and prominent. Infra-orbital ridge nearly obliterated. 

 Antennse slender, nearly attaining the base of the thorax, second joint nearly 

 as long as the third, last joint obliquely truncate. Thorax as long as wide, 

 narrower in front, sides feebly base more broadly arcuate, and with punctures 

 as in hi/perboreus, surface smooth, shining. Scutellum smooth. Elytra slightly 

 wider than the thorax, conjointly longer than wide, a moderate impression 

 common to both elytra at the tip of the suture and a very vague oblique im- 

 pression of the disc, surface very shining and with moderate punctures very 

 regularly but not densely placed, sparsely pubescent. Abdomen very sparsely 

 punctate and pubescent, beneath more distinctly punctured than above. 

 Femora punctulate, tibiae spinulose externally. Length .30 inch; 7.5 mm. 



The sixth ventral of the male is triangularly emarginate, the ante- 

 rior tarsi are feebly and nearly equally dilated in both sexes. 



The post coxal process is triangular, translucent. 

 " The color is black, shining with decided aeneous lustre, the antennae 

 and legs piceous. 



Occurs at Vancouver, Crotch. 



Q. ferox Lee. Proc. Am. Philos. Soc. 1878, p. 388. — Head orbicular, strongly 

 constricted behind, with the regular punctures as in vernix and numerous
