AMERICAN COLEOPTERA. 165 



Occurs from the Lake Superior region westward to Vancouver, and 

 northward to Alaska. 



I have seen specimens of Maklin's species and have no doubt of its 

 identity with brunnipennis, although I have no type of the latter. 



Q. debilis n. sp.— Head oval, with punctures as in hi/perboreus. Eyes 

 large, longitudinal, oval, not prominent. Infra-orbital ridge extremely feeble. 

 Labrum truncate. Antennae as in hi/perboreus. Thorax as in hi/perboreus, sur- 

 face (also the head) distinctly alutaceous. Scutellum smooth. Elytra a little 

 wider than the thorax, conjointly as wide as long, surface finely alutaceous, 

 very sparsely and finely punctate, sparsely pubescent. Abdomen sparsely 

 punctured and pubescent, a little more densely and finely at the basal por- 

 tion of each segment, beneath as above. Femora punctulate, tibiae spinulose. 

 Length .18— .24 inch; 4.5—6 mm. 



Sexual characters as in hyperhoreus. 



Color piceous without metallic lustre, inflexed posterior of the elytra 

 testaceous. Legs testaceous, tibiae piceous. 



Post coxal process short, transparent. 



Two specimens are before me, the larger, from Clear Lake, Cali- 

 fornia, has the elytra more distiuctly punctured than the smaller and 

 the punctures more numerous, the same being the case on the abdomen. 

 They are however representatives of one species. 



Clear Lake, California, and Vancouver, (Crotch). 



Q. prostans n. sp.— Head orbicular, a little wider than long, posteriorly 

 strongly constricted, front slightly triangularly.impressed, without punctures, 

 a small puncture at the base of the antennse, a larger at the inner margin 

 of the eye, three others arranged longitudinally on the occiput one of which 

 touches the eye. Labrum truncate with a slight impression at middle. Eyes 

 large and very prominent. Infra-orbital ridge obsolete. Antennse slender, 

 attaining the middle of the thorax, second and third joints equal, last obliquely 

 truncate. Thorax a little longer than wide narrower in front, sides feebly, 

 base more distinctly arcuate and with punctures as in hyperboreus, surface 

 smooth, shining. Scutellum smooth. Elytra as wide as the thorax, conjointly 

 a little longer than wide, a feeble longitudinal impression along the suture a 

 little deeper at the tip, surface shining, with moderately coarse and rather 

 closely placed punctures and few blackish hairs. Abdomen very sparsely 

 punctate and with few black hairs, the segments with a slight impression 

 each side of the middle in which the punctuation is denser and finer and the 

 pubescence greyish, beneath sparsely punctulate. Femora sparsely punctured, 

 tibiae spinulose externally. Length .22 inch; 5.5 mm. 



The sixth veutral of the male is emarginate, the anterior tarsi 

 dilated, in the female very feebly dilated. 



The color is uniformly black and shining, with a feeble aeneous 

 tinge, the legs and anterior coxae testaceous and the tibiae piceous. 

 Antennae piceous. 



Occurs in northern California and Vancouver.
