AMERICAN COMPONENTS OF THE TENTYRIIN^ 5 II 



cristata^ subangvilarly prominent at the sides just before the eyes, 

 the third and fourth antennal joints equal in length ; prothorax 

 but slightly wider than long, formed as in cristata and similar in 

 its very coarse and crowded foveas, without the two submedian 

 impressions but with a distinct impression near each side at about 

 the middle, the apex broadly sinuate, the apical angles somewhat 

 advanced but rounded ; elytra at least three-fourths longer than 

 wide, gradually ogival at tip, with the individual angles acutely 

 prominent and somewhat divaricate, the sides parallel and broadly 

 arcuate, very distinctly wider than the prothorax, the humeri very 

 obtuse, broadly but very obliquely exposed at base ; elevated ridges 

 irregularly crenulate along the summit, the intermediate series 

 composed of somewhat close-set carinules, the intervals each with 

 a single series of rather coarse, close-set and finely tuberculiferous 

 punctures; abdomen coarsely, closely cribrate. Length 13. 0-15.0 

 mm. ; width 4.2-4.9 mm. California (Monterey) ...carinata Lee. 

 Form much shorter and relatively stouter, black, the small hairs un- 

 usually short and inconspicuous ; head as in carinata^ subangu- 

 larly prominent before the eyes and arcuately narrowed thence to 

 the apex, the antennas similar, piceous in color; prothorax dis- 

 tinctly wilder than long, otherwise as in carinata^ the apex similarly 

 sinuate and the angles slightly advanced but rounded, the lateral 

 impressions distinct ; elytra barely one-half longer than wide, the 

 more elevated ridges a little higher and almost evenly though very 

 closely tuberculose, the carinules of the intermediate series more 

 widely spaced, the finely tuberculiferous punctures of the intervals 

 less close-set, the apex very obtusely rounded, with the individual 

 angles scarcely at all prominent or divaricate, the sides parallel 

 and arcuate, the humeri only slightly exposed at base ; abdomen 

 extremely coarsely but not quite so densely cribrate. Length 

 12. 0-14. 5 mm. ; width 4.4-5.2 mm. California (locality unre- 

 corded), — Cab. Levette , segnis n. sp. 



7 — Body moderately slender, convex, the elytra rather shining, black, 

 the small hairs not conspicuous ; head rather longer than wide, 

 very coarsely and subconfluently foveate basally, less coarsely so 

 before the middle from a well defined transverse line, the sides 

 abruptly prominent before the eyes, obliquely and not very arcu- 

 ately narrowed thence to the apex, with the sides notably reflexed ; 

 antennaj with the third and fourth joints equal ; prothorax evi- 

 dently wider than long, widest at apical third, where the sides are 

 broadly arcuate, rather strongly converging thence to the base, 

 becoming feebly sinuate, the basal angles acute and more or less 

 prominent, the apex transverse, feebly sinuate at the middle and 

 near each of the angles, which are rounded and not more produced 

 than the median lobes ; surface very coarsely and confluently 

 foveate, evenly and moderately convex, feebly impressed near each 

 side at about the middle, the sides rather broadly, strongly reflexed ; 

 scutellum large, transverse, very coarsely sculptured ; elytra three- 

 fourths to four-fifths longer than wide, distinctly wider than the
