AMERICAN COMPONENTS OK THE TENTYRlINyE 507 



one-half times as long, gradually aiul arcuately narrowed to the 

 narrowly obtuse tip in apical two-fifths, the sides parallel and 

 evenly, moderately arcuate to the obtuse and subangulate but 

 bluntly rounded humeri, the basal line thence to the peduncle 

 somewhat oblique; surface with fine serial sculpture as in dcli- 

 catiilus^ the alternate series subelevated laterally ; abdomen finely, 

 sparsely punctured medially. Length 3.0 mm.; width i.i mm. 

 California (southern) nebulosus n. sp. 



9 — Body formed nearly as in nebjilostts and, similarly, only moder- 

 ately shining; head a little larger and more broadly truncate at 

 apex than in nebuIo<;7is^ similarly sculptured, the eyes similar, the 

 upper lobe elongate, the antennje rather stouter ; prothorax rela- 

 tively rather broad, nearly three-fourths wider than long, the sides 

 broadly and moderately arcuate, more converging toward base 

 than in the preceding, the basal angles similar, the apical less 

 anteriorly prominent and still more blunt, the apex evenly sinuate ; 

 surface strongly, moderately closely and not so finely punctate 

 medially, with the narrow median smooth line better defined, 

 coarser, moderately dense and subrugose laterally; elytra nearly 

 as in nebjilosiis but equal in width to the prothorax and somewhat 

 more abruptly, obtusely ogival posteriorly, the sculpture almost 

 similar; abdomen finely but strongly, sparsely punctured medially. 

 Length 3.2 mm.; width i.i mm. California (Kern Co.). 



bicolor n. sp. 



10 — Form nearly as in the preceding but still smaller in size, blackish- 

 piceous, the legs rufous, moderately convex, rather shining; head 

 small, of the usual form, the asperate punctures moderately close ; 

 prothorax one-half wider than long, the sides moderately arcuate, 

 straighter toward apex and base, more strongly converging toward 

 the latter, the former almost truncate, the angles but slightly prom- 

 inent and blunt, the basal angles very obtuse though distinct ; sur- 

 face with fine and rather sparse punctures medially, v/ith a narrow- 

 smooth line, but little larger or closer but more asperate laterally ; 

 elytra equal in width to the prothorax and barely one-half longer 

 than wide, obtusely ogival behind, the sides parallel and feebly 

 arcuate to the obtusely angulate but blunt humeri, the sculpture 

 nearly as in dclicatuhis though rather finer, the alternate series 

 slightly prominent laterally ; abdomen somewhat finely, sparsely 

 punctured, coarsely and more closely so laterally. Length 2.75 

 mm.; width 0.9 mm. California (near San'Diego). 



deficiens n. sp. 



The scutellum is confined to the depressed part of the elytral 

 base, forming part of the peduncle as in Batultodes, but here, 

 instead of being evenly triangular with straight sides, it is 

 produced toward tip, with the sides of the narrow produced part 

 parallel and nearly straight and the apex rounded.
