This species resembles ustalatitm so closely as to require no special 

 description. It differs by its less convex form, with the prothorax 

 less suddenly and less strongly narrowed behind and the elytra more 

 finely striato-punctate, with the intervals flat or nearly so. The 

 sides of the thorax are less strongly arcuate in front and less deeply 

 sinuate behind. The color is usually more brownish than that seen 

 in the preceding species and the spots on the elytra ai-e usually larger 

 and paler, especially the posterior, which are often nearly white and 

 are not infrequently united at the suture. The size varies from .18- 

 .26 inch ; 4.5-6.5 mm. 



It occurs in the Hudson Bay Territory, the Lake Superior region, 

 Manitoba, Minnesota, Nebraska, the Rocky Mountain region and 

 westward to the Pacific coast. 



52. Bi ruscieruin Mots. — Form slender, depressed. Head and thorax ieue- 

 ous or nigro-seueous, the elytra very pale testaceous with a narrow rufous or rufo- 

 piceous line extending along the suture to behind the middle, where it ends in a 

 sub-pentagonal spot of the same color, which is often connected with the margin 

 each side by a fine transverse line. Head scarcely as wide as the thorax at apex ; 

 palpi more or less rufous, darker towards the tip; antennae about one-half as long 

 as the body, fuscous, the basal joints paler. Prothorax nearly one-half wider 

 than long, narrower at base than apex, slightly rugose at base ; apex nearly trun- 

 cate ; median line distinct, abbreviated in front; transverse impressions moder- 

 ately distinct ; basal impressions broad, deep, bistriate ; sides with the margin 

 very narrowly reflexed, arcuate in front, sinuate behind ; hind angles subrect. 

 angular, finely carinate. Elytra about one-half wider than the thorax, oblong- 

 ovate, finely striate, more finely towards the sides and apex ; strife finely punc- 

 tate, obsoletely so towards the tip, the five inner entire, the fifth grooved at apex ; 

 third stria with the first dorsal puncture in front of the middle, the second about 

 one-fourth from tip; intervals flat. Beneath black, shining. Legs rufo-testace- 

 ous, the femora often darker. Length .17-. 20 inch ; 4.25-5 mm. 



A very pretty little species. It seems most closely related to lu- 

 cidum, but is distinct by its more depressed form, with the thorax 

 more narrowed behind, and the elytra more finely striate, as well as 

 by its peculiar markings and smaller size. 



The above name has several years priority over that of mixtmn, 

 suggested for it by Dr. LeConte (List Col. N. Am., 1863, p. 14j. 



The specimens in the LeConte collection are from Alaska. It 

 occurs also locally throughout the Rocky Mountain region. It was 

 taken in moderate abundance by Mr. Bowditch and myself at Gun- 

 nison, Col., and in the San Luis Valley, and I have received it from 

 Salida, in the same State, from Mr. H. F. Wickham. It is also 

 known to me from Manitolja, Montana, Wyoming, Utaii and Oregon 

 (Henshaw).
