CICINDELID.E AND CARABID/E 73 



the sides rounded, converging, becoming almost straight posteriorly; 

 surface, somewhat finely but very deeply and closely punctate, 

 broadly and densely rugose toward the sides, moderately convex, 

 feebly declivous laterally to the sharply elevated marginal bead 

 but not reflexed even basally, though the rather deep narrow im- 

 pressions give somewhat this appearance, the basal angles rather 

 broadly rounded and only very moderately produced; elytra short, 

 oblong-oval, a fourth to third longer than wide, the humeri rather 

 evident though very broadly rounded. Length 14.5-15.8 mm.; 

 width 7.2-7.7 mm. Northern California. Vancouver Island- 

 Walker pimelioides Walk. 



Body narrower and more oblong in form, similar in coloration and lustre; 

 head a little smaller, finely and sparsely punctate and covered 

 throughout with vermicularly anastomosing incised lines, feebly 

 rugose but not more punctate toward the eyes; mandibles almost 

 similar, except that the strigaB are still finer and feebler; antennae 

 almost similar; prothorax not so broad, distinctly less than twice as 

 wide as long, otherwise nearly similar, except that the basal angles 

 are much more narrowly rounded and more produced posteriorly, 

 the fine punctures medially much less close-set and the lateral ru- 

 gosity less dense, the impressions and side margins similar; elytra 

 more narrowly oval, two-fifths longer than wide, the humeri broadly 

 rounded; side margins similarly opaque and still more narrowly 

 reflexed; tarsi similarly moderately long, slender. Length (cf ) 14.5 

 mm. ; width 7.0 mm. California (Yreka), Levette. 



pustulosus n. sp. 



8 Longitudinal and transverse lines of the elytra apparently about 

 equally distinct. Body brownish-black, the elytra reticulate; head 

 and prothorax minutely punctured; mandibles flattened above, 

 rugose with oblique lines; prothorax minutely punctate, the punctures 

 larger and confluent on the lateral margin, the posterior angles 

 rounded, extending backward a little beyond the basal line; elytra 

 suborbicular, reticulate, the " longitudinal lines not more dilated 

 or profoundly impressed than the transverse ones, which are not 

 continuous, the points of intersection not distinguished by a punc- 

 ture;" three punctured series obsolete, their traces hardly discernible 

 in a certain light and not differently colored. Length more than 

 15 mm. Inhabits Arkansas luxatus Say 



Longitudinal lines of the elytra, except near the suture, more faint than 

 the transverse lines 9 



9 Form moderately stout, convex and shining, deep black; head three- 

 fifths as wide as the prothorax, very finely and remotely punctulate, 

 the antero-lateral impressions expanding very shallowly at the sides 

 of the front and with some radiating rugulse; mandibles rather short, 

 thick, not bent inward much apically and very faintly strigose; 

 seta near the eyes transversely doubled; prothorax rather large, 

 barely three-fifths wider than long, the sides broadly rounded, 

 converging and straighter behind, the angles rather narrowly rounded 

 and well produced; surface minutely and remotely punctate, broadly, 

 feebly reflexed and coarsely, sparsely rugose and punctate laterally,
