American Caraboidea 147 



Loricera uteana n. sp. — Shining, black, the anterior parts with feeble 

 greenish lustre, the elytra not evidently metallic; under surface deep 

 black; legs piceous-black, the tibiae and tarsi paler, the anterior and 

 middle trochanters bright testaceous as usual; head more than three- 

 fourths as wide as the prothorax, transverse, the eyes large and promi- 

 nent, the nuchal constriction deep and sharp; surface rugulose laterally, 

 the two anterior pits and occipital median line deeply impressed; mandi- 

 bles pale; antenna; black, half as long as the body, the basal joint testa- 

 ceous at base; prothorax only between a fourth and fifth wider than 

 long, the moderately refiexed sides broadly, evenly arcuate, more oblique 

 only near the base, becoming just visibly sinuate at the angles, which 

 are more than right though very sharp; surface smooth, sparsely punc- 

 tured at base, the median line broadly impressed; anterior impression 

 wholly wanting, the posterior evident though not deep; fovese broadly 

 concave, extending sinuously forward in sharply and deeply impressed 

 form through basal two-fifths of the length; apex very faintly sinuato- 

 truncate and strongly beaded along the neck, the outer angles very 

 broadly rounded, undefined; elytra oblong, with parallel and feebly 

 arcuate sides, more rounding basally, one-half longer than wide and 

 one-half wider than the prothorax, oblique and very obtusely ogival 

 at apex; striae twelve in number, impressed suturally, moderately punc- 

 tate, the punctures obsolescent posteriorly; lateral striae very fine, the 

 twelfth deep, the marginal interval with an irregular series of moderate 

 punctures, the third interval with three large and broadly impressed 

 fovese; abdomen latero-basally, sides of the metasternum and the met- 

 episterna coarsely punctate. Length 7.3 mm.; width 2.9 mm. Utah

Differs from neoscotica in its bipartite and more obscure lustre, 

 less elongate form of body, narrower and basally less narrowed 

 prothorax and more elongate basal joint of the antennae. From 

 californica Lee, it differs in its larger size and broader outline, much 

 less transverse prothorax, not so sinuate at the sides basally, larger 

 head, less intensely black coloration and in many other features. 



Besides the twelve elytral striae, this genus is peculiar in having 

 no trace of a scutellar stria, but the second stria fails to attain the 

 base and apparently ends in a somewhat larger puncture; the elytra 

 have each a feeble apical indentation. The male has the first 

 three anterior tarsal joints rather widely dilated, densely spongy- 

 pubescent beneath and forming an elongate-oval patellum. The 

 tarsi are long and very slender. 



Leistus Froh. 



Dr. G. H. Horn, in his monograph on the tribes and genera of the 

 Carabidae, forms a tribal group Nebriini, to which he assigns, in
