278 MEMOIRS ON THE COLEOPTERA 



6 Form suboblong, moderately convex, slightly shining, except in a 

 rather large area just behind the elytral fascia, where the surface 

 loses its punctures but becomes finely and very densely, granularly 

 rugose and opaque; color black, the meso- and metasterna pale 

 testaceous, the abdomen piceous, the legs pale red-brown; pubes- 

 cence everywhere rather long, pale but not dense; head not coarsely 

 but very deeply and closely punctate, the eyes not quite divided; 

 antennae (c?) three-fourths as long as the body, slender, pale, the 

 second joint two-fifths as long as the third; prothorax slightly shorter 

 than wide, obtusely angulate at the middle of the sides, scarcely 

 more narrowed basally than apically, the base truncate; apex broadly 

 arcuate, the surface convex, even, with rather small deep perforate 

 and close-set punctures, the narrow smooth median line obliterated 

 medially; scutellum extremely minutely and densely punctate and 

 closely pubescent; elytra pale anteriorly, blackish behind the fascia, 

 but little more than twice as long as wide, narrowing just visibly 

 from the rather prominent humeri to the broadly and abruptly 

 obtuse apex, the punctures small but strong, close in the testaceous 

 and rather shining area between the white and arcuate, narrowly 

 suturally interrupted fascia and the base, very fine and sparse at the 

 polished apex; femora strongly clavate. Length (c?) 8.5 mm.; 

 width 2.5 mm. California. [P. vulneratus Lee., Kept. Expl. and 

 Surv., 1857, XII, p. 60] vulneratus Lee. 



Form narrower, the size much smaller, similar in coloration, except that 

 the dark parts are piceous-black and the white elytral fascia nar- 

 rower and more widely interrupted at the suture; lustre much more 

 shining, the pubescence very much shorter and finer, sparse and in- 

 conspicuous; punctures of the head and prothorax smaller and much 

 less close, separated by more than their diameters on the latter, 

 becoming fine and sparse medially and apically, the smooth median 

 line indistinct except basally; prothorax nearly as long as wide, the 

 outline nearly as in the preceding but much more narrowed basally; 

 scutellum with extremely minute dense punctulation and very 

 minute close hairs, much smaller than in vulneratus; elytra perfectly 

 parallel, only about a third wider than the prothorax, more than 

 twice as long as wide, abruptly and very obtusely rounded at apex, 

 the punctures coarse, impressed, separated by fully their own diam- 

 eters and much larger than in vulneratus anteriorly, becoming 

 small, feeble and closer, with the surface feebly subrugulose, behind 

 the fascia, this area rather shining and not opaque as in vulneratus, 

 excessively minute and remote at the polished apex; legs shorter 

 than in the preceding, the apical femoral swelling less developed. 

 Length (d 1 ) 5.6 mm.; width 1.4 mm. California (Sta. Cruz Mts.).

7 Punctures of the upper surface small and close-set, generally sparser 

 discally on the pronotum 8 



Punctures of the upper surface notably coarse 10 



8 Posterior fasciae of the elytra very oblique; form narrow and notably 

 elongate; color deep black throughout, with the part of the elytra 

 before the anterior fascia faintly piceous, the legs black typically;
