American Caraboidea 167 



without trace of metallic lustre; head three-fifths as wide as the 

 prothorax, with the eyes moderately prominent, rather narrow, the 

 rugosity not at all close; antennae as long as the head and prothorax, 

 the fifth joint with a very small shining area having very few punc- 

 tures and not at all like the longer areas of fine and denser punctures 

 on the succeeding joints; prothorax rather small, scarcely two- 

 thirds wider than long, widest anteriorly, the sides rather strongly 

 rounded, somewhat finely and not strongly reflexed, becoming 

 notably oblique and straight behind the middle, the angles broadly 

 rounded and but very slightly produced behind; surface with sparse 

 and deep but moderate punctures, which are more or less connected 

 by feeble vermiculate lines, coarser and more closely rugose laterally 

 and in the extremely shallow elongate fovese; stria short, fine; 

 scutellum angularly impressed at base; elytra two-fifths longer than 

 wide, a third wider than the prothorax, oblong-oval, the tegulae 

 broadly convex, pointed behind, obsolescent at the humeri, not 

 graniform at the sides though taking the form of coarse and widely 

 separated, pointedly convex granules apically; anterior male tarsi 

 very narrowly dilated. Length (d^) 15.5 mm.; width 6.7 mm. 

 Oregon. [C. zimmermanni Csy. nee Lee., olim.] debilis n. sp. 



Head almost uniformly punctate and rather sparsely, the punctures but 

 little smaller and sparser antero-medially, smaller and closer on the 

 neck; body larger and much broader than in debilis, deep black, 

 rather shining, the head well developed, fully three-fifths as wide as 

 the prothorax, with more prominent eyes than in debilis, the an- 

 tennae nearly similar; mandibles more strongly arcuate; prothorax 

 nearly four-fifths wider than long, the general outline and sculpture 

 nearly as in debilis, but with the sides much more strongly reflexed, 

 conspicuously so toward base, the produced basal angles more 

 strongly rounded; median stria coarser, deeper and entire; elytra 

 notably short, subquadrate, moderately convex, just visibly longer 

 than wide, nearly one-half wider than the prothorax, the parallel 

 sides broadly arcuate, obtusely ogival at apex, the humeri rather 

 rapidly but not narrowly rounded, the margins sharply and strongly, 

 subevenly reflexed; tegulae convex, oblong-oval, prominently pointed 

 at their posterior ends, the eighth series with a few small remote 

 asperate punctures; the tegulae toward the sides and apex are 

 smaller, closer and more graniform; under surface sparsely punctate, 

 the legs and tarsi black. Length (9) 17.0 mm.; width 8.0 mm. 

 Utah (Parowan), — Spalding parowanus n. sp. 



Head much more finely and rather closely punctate, the punctures 

 obsolescent antero-medially, sparse and coarser in a transverse 

 sinuate band extending unbrokenly between the eyes; mandibles 

 short, with notably sparse and rather feeble sculpture; body 

 broader, oblong-oval, somewhat convex, deep black and rather 

 dull in lustre, the elytral tegulae very moderately convex at the 

 sides and apically 6
