American Caraboidea 183 



and third joints and less than apical third of the first spongiose. Length 

 (cf ) 13.5 mm.; width 5.5 mm. Oregon. 



Allied somewhat to confusiis Csy., but with more abbreviated, 

 more gradually posteriorly attenuate and more coarsely, closely 

 and deeply sculptured elytra. 



There are a number of forms closely allied to cordatus Lee, but 

 different; there is, however, so close a community of habitus, that I 

 could not venture to suggest a higher status than that of the sub- 

 species for them; those at present in my collection are as follows: 



Prothorax distinctly wider than long. Deep black, highly polished 

 throughout the upper surface, excepting the head with very faint 

 violaceous lustre; head broader, distinctly more than half as wide 

 as the prothorax, very smooth; fifth antennal joint more than 

 four times as long as wide; prothorax with inflated and evenly 

 arcuate sides, becoming parallel in basal fifth or sixth, the angles 

 broadly rounded; transverse impressions and longitudinal foveae 

 rather deep and distinct, the median stria deeply impressed, sub- 

 entire; elytra widest somewhat before the middle, gradually arcu- 

 ately acute behind, more parallel basally, with rather rapidly 

 rounding humeri, three-fourths longer than wide, four-fifths wider 

 than the prothorax; surface rather flattened, the striae coarse, very 

 feebly impressed, the punctures coarse, isolated and along virtually 

 unimpressed striae laterally; margins sharply and very narrowly 

 but strongly reflexed, not metallic; tarsi black, slender, the anterior 

 of the male slender, scarcely at all dilated, the second and third 

 joints and small apical area of the first loosely spongy-pubescent 

 beneath, the fourth with longer, finer hairs beneath. Length (cf') 

 12.8 mm.; width 5.2 mm. California (Monterey). Sta. Clara 

 Co.,— LeConte cordatus Lee. 



Prothorax much narrower, as long as wide; head narrower 2 



2 — Tarsi black. Surface polished, deep black, without distinct vio- 

 laceous lustre; head somewhat more than half as wide as the 

 prothorax; fifth antennal joint shorter, a little less than four times 

 as long as wide; prothorax subprominently rounded just before the 

 middle, the sides broadly arcuate and feebly converging thence to 

 the apex, oblique and straighter behind, gradually becoming almost 

 parallel basally, the angles moderately rounded; impressions and 

 foveae distinct; elytra two- thirds longer than wide, not quite twice 

 as wide as the prothorax, very gradually arcuately accuminate 

 behind from before the middle, the humeri very rapidly rounded; 

 sculpture nearly as in the preceding, the punctures not quite so 

 coarse. Length (9) 12.9 mm.; width 5.0 mm. California (near 

 San Francisco Bay) vemicatus n. subsp. 



Tarsi pale brownish-testaceous. Polished, deep black, without trace of 

 violaceous lustre, larger, more elongate tTian in the preceding; head 

 similar; fifth antennal joint four times as long as wide; prothorax
