punctate line, constricted at apex, rounded and snbparallel on the 

 sides. Elytra at base distinctly wider than the prothorax, a little 

 more than three times as long as the latter, wider behind ; strial 

 punctures coarse, deep and close-set; intervals finely but deeply, 

 evenly, not very closely punctate. Abdomen strongly punctate. 

 Length 3.4-4.3 mm.; width 1.4-1.8 mm. 



Alaska, Washington State and California (San Francisco and 

 Los Angeles). This is a very abundant, widely distributed and 

 constant species and may be easily recognized by the characters 

 stated in the table. In one immature specimen before me a large 

 region of the elytra toward the suture is piceous-black, confusedly 

 speckled with paler spots.

Oblong, rather convex, rufo-testaceous and feebly shining through- 

 out ; sterna and side-pieces piceseent ; vestiture sparse and scarcely 

 at all condensed in spots, consisting of short prostrate pale hairs. 

 Head deeply punctate, without frontal fovea, the beak in tlie female 

 moderately stout, feebly arcuate, distinctly longer than the head 

 and prothorax, deeply punctato-sulcate ; antennae inserted rather 

 behind apical third, the basal joint of the funicle subequal to the 

 next three. Prothorax one-half wider than long; sides parallel 

 evenly and rather strongly arcuate; apical constriction small and 

 strong, the apex four-fifths as wide as the base, broadly tubulate; 

 punctures moderate in size, narrowly separated, with a fusiform 

 impunctate space at the middle. Elytra at base nearly two-fifths 

 wider than tlie prothorax, almost four limes as long, scarcely per- 

 ceptibly wider behind the middle; sides convergent and nearly 

 straight in apical third, the apex narrowly obtuse; sutural notch 

 obsolete ; strial punctures not very large but deep, moderately 

 close-set; strife not imi)ressed ; intervals wide, minutely, indis- 

 tinctly punctate. Abdomen not coarselv, strongly, rather sparsely 

 punctured. Femora not very stout, the tooth small, distinct and 

 very acute. Length 4.3 mm.; width 1.8 mm. 



Alaska. Cab. LeConte. The single specimen, from which the 

 above outline is drawn, is a female, the abdomen being evenly con- 

 vex toward base. It is quite closely allied to luridus but is a 

 larger, stouter species, with shorter and thicker beak, always pale 

 in color and with decidedly smaller eyes, so that when the insect is 

 viewed in profile, there is a large part of the head visible above them.
