appearance to the basal regions, the latero-basal region scarcely at 

 all impressed but with numerous close-set strong punctures, which 

 extend finely and sparsely along the sides anteriorly; elytra three- 

 fifths longer than wide, about one-half wider than the prothorax, 

 parallel, with feebly arcuate sides; striae well impressed, the intervals 

 slightly convex, more distinctly suturad. Length (9) 4.0 mm.; 

 width 1.2 mm. California (Sacramento Co.), Koebele. A single 



example exstans n. sp. 



Pronotal punctures confined to the feebly impressed latero-basal region 



as usual 2 



20 Body moderately stout and convex; surface shining, testaceous, the 

 head piceous except basally, the pronotum mottled with piceous, 

 especially along and at a distance from each side; elytra with an 

 elongate blackish area parallel to the suture and frequently covering 

 most of the upper part of the disk;. under surface black, pale laterally 

 and anteriorly, the legs pale; head large, three-fourths to four-fifths 

 as wide as the prothorax, with rather prominent eyes; antennae 

 slender, half as long as the body; prothorax transverse, a third to 

 two-fifths wider than long, moderately rounded at the sides anteriorly, 

 the basal angles obtuse, sharply defined but seldom with trace of 

 minute prominence at their apices; surface smooth, with fine median 

 line, the foveae rounded, shallow and rather strongly and closely 

 punctate, the punctures not extending far from the foveae; elytra 

 one-half longer than wide, barely two-fifths wider than the prothorax, 

 the striae impressed and with moderately convex intervals. Length 

 (c? 9 ) 3.5-4.3 mm.; width 1.2-1.4 mm - California (Sta. Cruz to 



Humboldt). Abundant nubicollis n. sp. 



Body nearly as in rupestris but with very much less rounded sides of the 

 prothorax and less prominent eyes; surface shining, pale testaceous, 

 the vertex infumate; elytra each with an elongate blackish area; 

 under surface of the hind body and middle of the prosternum black, 

 the epipleura and legs very pale; head two-thirds as wide as the 

 prothorax, the eyes large but not very prominent; antennae half as 

 long as the body, very slender, feebly fusco-testaceous, clearer 

 basally; prothorax barely more than a fourth wider than long, the 

 sides rounded anteriorly, converging and nearly straight throughout 

 more than basal half, the basal angles obtuse, sharply defined but 

 not at all prominent at their apices; base and apex subequal; surface 

 with a strong entire stria, the foveae large, somewhat impressed, 

 strongly and closely punctate, separated from the sides by an unusu- 

 ally wide impunctate interval; elytra more than one-half longer than 

 wide, two-fifths wider than the prothorax, the ,striae moderately 

 impressed, the intervals evidently but not strongly convex. Length 

 (cf ) 3.8 mm.; width 1.3 mm. California (Sta. Cruz Mts.).
