much less bi'oadly, confusedly punctured toward the suture, the Im- 

 punctate space thence to the first medial series wider. Length 6.3 mm. ; 

 width 0.98 mm. Oregon (Portland), — H. F,Wickham..oregonus n. sp. 

 Form very slender, rather smaller in size, polished, convex; head moderate, 

 parallel, behind the antennae much longer than wide, the sides nearly 

 straight; basal angles broadly rounded, the punctures throughout near- 

 ly as in hamatus; prothorax notably narrow and elongate, two-fifths 

 longer than wide, the sides moderately converging, becoming somewhat 

 sinuate posteriorly, the apical angles rather narrowly rounded, punc- 

 tured nearly as in hamahis; elytra elongate, somewhat shorter than the 

 prothorax and much wider, distinctly wider than the head; abdomen 

 slightly wider than the head, punctulate as in the preceding species. 

 Length 6.0 mm.; width 0.8 mm. Wisconsin (Bayfield), — H. F. Wick- 

 ham. 1= corvinus Dej., i. litt.] protractas n. sp. 



7 — Body slender, convex, polished, black, the elytra and antennae blacklsh- 



piceous, the legs paler, dark testaceous; head well developed, the sides 

 straight and parallel or feebly diverging to the moderately rounded 

 basal angles; punctures nearly as in hamatus, those of the fiattened 

 post-ocular line obsolescent posteriorly and those of the under surface 

 sparse and inclined to serial arrangement laterally, broadly subobsolete 

 toward the middle; antennae rather thicker distally, the second joint 

 obviously longer and thicker than the third; prothorax slightly narrower 

 than the head, elongate, distinctly narrowed posteriorly, with the sides 

 somewhat arcuate, the angles broadly rounded; punctures of the dorsal 

 series strong, close-set, 10-12 in number, the sublateral short and 

 Irregular, of 5-6 punctures; toward the sides throughout the length 

 there are many other punctures tending to serial arrangement; elytra 

 elongate, slightly longer and much wider than the prothorax; abdomen 

 but slightly narrower than the elytra, minutely, sparsely punctulate. 

 Length 4.5 mm.; width 0.7 mm. California (Elsinore, — Riverside 

 Co. ) mollinns n. sp. 



8 — Second and third antennal joints equal in length as usual; strigilation 



of the under surface of the head subobsolete, the punctures deep and 

 close-set between the gular sutures anteriorly, elsewhere strong but 

 sparse, becoming obsolete toward base; body larger, stouter, polished, 

 black, the abdomen rather distinctly, and the prothorax just visibly, 

 piceoQs; entire elytra clear and bright rufous in color, the legs pale, the 

 antennae very dirk testaceous; head well developed, behind the an- 

 tennae distiuctly elongate, parallel, the sides nearly straight, the basal 

 angles well rounded; antennae parallel through the outer seven joints, 

 moderately thick as usual; punctures coarse, deep and close-set toward 

 the sides, the post-ocular flattened line also deeply and rather closely 

 though less coarsely punctured; prothorax distinctly elongate, narrower 

 than the head, the sides parallel and straight for nearly two -fifths from 

 the apex, then very feebly converging to the base, the angles only slightly 

 rounded; punctures strong, arranged nearly as in haynatus; elytra ample, 

 longer than wide, much wider than the prothorax and fully as long, 

 wider thai the head, rather strongly punctured almost as in hamatus, 

 the two medial series, however, only distinct to a little behind the mid- 

 dle ; abdomen rather closely and strongly punctulate toward the sides.
