CERAMBYCID^E 223 



7 Form robust, black, not at all densely clothed with long cinereous 

 pubescence; head densely punctate, the prothorax moderately, the 

 latter convex, constricted at apex, the sides before the middle abruptly 

 rounded, parallel posteriorly, the surface obsoletely canaliculate; 

 elytra subdepressed dorsally, the sides obliquely impressed, the apices 

 subobliquely attenuate, then obtusely rounded, tinged with vio- 

 laceous, less densely punctate, the punctures finer posteriorly; legs 

 densely fusco-pubescent ; antennae fuscous, black at base. Length 

 14.2 mm. Oregon mollipilosa Lee. 



Form stout, the elytra less flattened dorsally than in the preceding, with 

 the sides less impressed behind the humeri and less broadly rounded 

 at the elytral apex, black, pubescent; head densely punctate and 

 canaliculate; prothorax densely punctate, the median line smooth 

 posteriorly, shorter than wide, the sides anteriorly notably rounded, 

 strongly margined, abruptly constricted and briefly tubulate at 

 apex; elytra rather closely punctate, more finely posteriorly, parallel, 

 obtuse at apex. Length 12.5 mm. California (Sacramento). 

 [fusca Lee. founded also upon a single specimen, taken in the same 

 locality and by the same collector, is probably only the paler 

 dimorphic form of lugens] lugens Lee. 



Form stout, moderately convex, shining, deep black, the elytra with 

 feeble greenish-metallic lustre; head very densely punctate, the 

 sides feebly arcuato-convergent from the scarcely prominent eyes 

 to the base; third and fourth antennal joints short, equal, barely 

 more than twice as long as wide; prothorax wider than long, only 

 moderately constricted at apex, moderately and arcuately swollen 

 at the sides before the middle, evenly convex, with the very moderate 

 punctures well separated and a smooth median line except anteriorly, 

 the pubescence notably long, yellowish, very coarse and conspicuous; 

 elytra parallel, conjointly very obtusely rounded at tip, three- 

 fourths longer than wide, less than twice as wide as the prothorax, 

 the punctures well separated, deep and perforate, rather coarse, 

 becoming small but still strong apically, the hairs rather long, coarse, 

 bristling and yellowish; abdomen finely and feebly but rather closely 

 punctulate. Length 11.5 mm.; width 4.0 mm. California (San 

 Francisco) tumida Lee. 



8 Elytra black, with the feeblest possible trace of aeneo-viridate lustre 

 laterally, stout, somewhat grayish-black throughout, the pubescence 

 everywhere unusually long, rather coarse, yellowish-cinereous and 

 conspicuous, bristling and less dense on the elytra, unusually long 

 on the abdomen; head finely but deeply, densely punctate, the sides 

 behind the eyes very feebly converging to the base; antennae thick, 

 the equal third and fourth joints barely twice as long as wide; 

 prothorax nearly as long as wide, the apex broadly and deeply 

 constricted but only very moderately narrowed, the sides very broadly 

 and feebly rounded, not prominent; surface finely, rather sparsely 

 punctate, with a smooth median line behind the middle; elytra 

 short, barely three-fourths longer than wide, strongly tapering from 

 base to the rather narrowly rounded apex, scarcely one-half wider 

 than the prothorax, the punctures notably coarse and sparse basally,
