behiud and the hind angles sub-obtuse. It is slightly more convex 

 and less broad than quadrlfuveolatiun, with the elytra less deeply 

 striate and the dorsal punctures smaller, the legs paler, and the first 

 joint of the antennjs rufous. The elytra are less oval than in the 

 first-named species. 



This species has not heretofore been described. The name here 

 used was proposed by Dr. LeConte in his " List" (Smiths. Misc. Coll., 

 1863-6, vi, p. 14) for " mcertam var. Mann." Mannerheim's de- 

 scription (Bull. Mosc, 1852, xxv, p. 301) undoubtedly applies to 

 the species described as incertum by Motschulsky, and no variety is 

 indicated by him. LeConte's type was received by him from Europe, 

 probably from Chaudoir, and it seems to me most likely that it was 

 sent under the name which LeConte proposed to supplant. 



The only specimens known to me are in the LeConte collection. 

 The type is probably from Alaska. The othei- three are from British 

 Columbia. 



34. B. qiiadriroveolatiiin Mots. — Form moderately broad, feebly con- 

 vex ; color black, slightly a-ueous. Head as wide as the thorax at apex ; palpi 

 black; antennse about one-half the length of the body, black. Prothorax about 

 one-half wider than long, scarcely narrower at base than apex, slightly rugose at 

 base; apex nearly truncate ; median line deep, abbreviated before and behind; 

 transverse impressions moderately distinct; basal impressions broad, deep, bi- 

 striate; sides with the margin narrowly retlexed, slightly arcuate in front, at 

 most obsoletely sinuate behind ; hind angles subrectangular, carinate. Elytra 

 more than one-half wider than the thorax, oblong-oval, moderately deeply striate ; 

 strise entire, inipunctate, the outer less deeply impressed, the fifth slightly grooved 

 at tip ; third stria with the dorsal punctures large, the first about the middle, the 

 second about one-fourth from apex ; intervals nearly flat. Beneath black, shining. 

 Legs black. Length .16-. 21 inch ; 4-5.25 mm. 



This species seems most nearly related to funereum, but may be 

 recognized by its broader, less convex form, proportionally wider 

 thorax as compared with its length, with the base scarcely narrower 

 than apex and the sides at most obsoletely sinuate behind. The 

 elytra are less deeply striate, with the dorsal pimctures larger and 

 differently placed, and the legs are black. 



As is the case with many of the species of this group, I have had 

 but a small amount of material for study, as it seems rare in collec- 

 tions. 



It is known to me from Alaska, Vancouver Island and Washing- 

 ton. 



35. B. incertum Mots. — Form broad, moderately depressed; color varying 

 from black or bluish black to aeneous, shining. Head as wide as the thorax at
