Coleopterohxjical Notices, III. oi) 



the prothorax, flattened above, rather coarsely, extremely densely punctate 

 and dull ; sides behind the eyes parallel for a very short distance, then 

 rounded to the neck ; temjtora shorter than the eye ; antennje very slender, 

 subequal in length to the body, third joint much shorter than the fifth and 

 but slightly longer than the fourth, the fifth thicker toward apex than the 

 others. Prothorax slightly wider than long, the apex broadly arcuate, three- 

 fourths> as wide as the base ; sides strongly but evenly arcuate, sinuate near 

 base and apex ; disk narrowly impunctate but scarcely impressed along the 

 middle, rather coarsely, very densely punctate, the punctures generally not 

 in actual contact. Scutellum rather longer than wide, acutely rounded at 

 apex. Elytra at base not quite one-half wider than the prothorax, two and 

 one-half times as long as wide ; sides rather strongly convergent from base to 

 apex, the latter narrowly rounded, not at all truncate ; disk very coarsely, 

 deeply, not closely punctate, the punctures becoming slightly smaller but not 

 denser toward apex, each bearing a very short coarse hair. Legs rather long 

 and slender. Length 8.0-8.8 mm. ; width 2.5-3.0 mm. 



California (Sta. Cruz Co.). 



This species is somewhat allied to longicornis and bamlis, but 

 differs in its shorter, more convex form, much coarser, sparser 

 punctuation, shorter, sparser pubescence, and also in coloration ; 

 from atra it differs greatly in the parallel sides of the head behind 

 the eyes, in the distinct basal constriction and prominent basal 

 angles of the prothorax, and in its much more crowded pronotal 

 punctuation. 



A specimen from Nevada is nearly similar, but has the pubes- 

 cence still more minute and the elytra parallel and scarcely more 

 than twice as long as wide ; this is probably the female of the 

 above-described male. 



STRAi\GALIA Serv. 



The sexual characters of this genus form an exceedingly inter- 

 esting study, as they manifest themselves strongly and in several 

 directions. The fifth segment of the male is sometimes very large, 

 dilated and strongly excavated beneath as in virilis, and, to a less 

 degree, strigosa; in addition it will be noticed that this segment is 

 also invariably impressed or excavated beneath toward tip in the 

 female as well as the male, and in sexnotata the impression is (piite 

 as deep in the former as in the latter sex, and involves even more 

 of the surface of the segment. 



The community of impressions and excavations of the fifth ven- 

 tral segment to both male and female is noticeable in many parts
