American Caraboidea 237 



than usual, the subsutural part more posteriorly produced, the 

 elytra divaricate at tip, the outer limit of the truncature broadly 

 rounded; micro-reticulation rather feeble; two punctures at the 

 third stria near basal third and apical fourth; scutellar stria rather 

 long, feeble, parallel and close to the suture. Length 8.0 mm.; 

 width 3.3 mm. New York (near the city) enormis n. sp. 



Elytra with impressed striae and more or less convex intervals, the 

 narrow reflexed side margins abruptly pale testaceous; body 

 smaller in size 8 



8 — Elytra blue-black; under surface pale, the epipleura and abdomen 

 more obscure rufous, piceous posteriorly; head finely but strongly 

 rugulose, fully four-fifths as wide as the prothorax, with very 

 prominent eyes; antennae slender, half as long as the body, rufous, 

 somewhat clearer basally; prothorax four- fifths wider than long, 

 in form nearly as in grandis, the rounded sides very converging 

 anteriorly, broadly reflexed, the convex parts rugulose in coarse and 

 somewhat wavy lines; basal peduncle distinct, the transverse groove 

 deep; scutellum small, pale, the margining parts of the strial interval 

 and the basal margin of the elytra also pale; elytra nearly one-half 

 longer than wide, feebly inflated posteriorly, four-fifths wider than 

 the prothorax, the sinuous truncature as usual; striae deeply im- 

 pressed, finely punctulate, the sixth and seventh becoming gradually 

 more approximate basally, the intervals strongly convex; seventh 

 stria slightly, the eighth much, more feebly impressed; legs slender, 

 pale, the tarsi not noticeably darker. Length 6.2 mm.; width 2.8 

 mm. Arizona pimalis n. sp. 



Elytra brighter steel-blue; under surface, entire legs and epipleura pale 

 testaceous, the abdomen piceous-black; head moderate, in part 

 feebly punctulate or subrugulose, smooth medially, having well 

 developed and very prominent eyes, fully four-fifths as wide as the 

 prothorax; antennae rufous, nearly half as long as the body; pro- 

 thorax much shorter than in the preceding, twice as wide as long, 

 the sides not quite so strongly though widely and more gradually 

 reflexed, strongly rounded, very convergent apically; basal angles 

 feebly subprominent at tip; surface finely rugulose, the basal 

 peduncle and groove almost similar; median stria not impressed as 

 it is in pimalis, and extremely fine; elytra oblong, slightly inflated 

 behind, about a fourth longer than wide, very nearly twice as wide 

 as the prothorax, the feebly sinuate truncature limited externally 

 by broadly rounded angles; striae fine, not evidently micro-punctu- 

 late, rather deeply impressed; intervals distinctly convex, though 

 not quite so strongly as in grandis, much less convex than in pimalis; 

 anterior tarsi of what appears to be the male only a little less slender 

 than those of the female and perfectly symmetric. Length 5.8- 

 6.0 mm.; width 2.7 mm. Arizona (Tugson), — J. F. Tucker. Five 

 specimens tuckeri n. sp. 



9 — Body larger, rather ventricose, pale testaceous, the head and elytra 

 black, the latter with pronounced blue lustre; under surface pale, 

 the epipleura rufo-piceous, the abdomen black; legs pale, the 

 tibiae distally gradually darker, the tarsi black or nearly so; head
