92 CASEY 



closely punctate, much more finely so basally, unimpressed, the 

 anterior canthus somewhat narrowly rounded and very much less 

 prominent than the posterior; antennae blackish, slender ; pro- 

 thorax fully two-thirds wider than long, the sides broadly rounded 

 and converging anteriorly, becoming nearly straight and parallel 

 from well before the middle to the base, the apex three-fourths as 

 wide as the base, broadly, circularly sinuate, the angles right and 

 but slightly blunt ; punctures fine but strong and moderately close- 

 set, becoming still stronger and a little closer, perforate and con- 

 spicuous laterally, the marginal bead very fine ; scutellum as in 

 ancil/a, broadly triangular, the elytra also similar in outline, very 

 obtuse behind, the surface nearly smooth, slightly rugulose pos- 

 teriorly, the punctures sparse but subperforate and very distinct; 

 prosternum unusually finely, sparsely punctate, the process rather 

 wide, circularly rounded at tip, broadly and feebly impressed 

 along its median line ; abdomen very minutely, sparsely, the hind 

 femora rather distinctly and less sparsely, punctate. Length 9.4 

 mm.; width 4.4 mm. California (Lancaster), — Mr. H. F. 

 Wickham. A single female oblonga n. sp. 



6 — Form somewhat elongate, parallel, moderately convex, rather 



dull and strongly alutaceous, black with a feeble piceous tinge, 

 glabrous, the elytral punctures with very small inconspicuous 

 hairs; head rather finely but strongly, not densely punctate, un- 

 impressed, the anterior canthus rather narrowly rounded, but 

 little less prominent than the posterior; prothorax nearly as in 

 oblonga though a little less transverse, fully one-half wider than 

 long, the sides scarcely becoming parallel posteriorly but very 

 feebly converging from the base though less arcuate, the punctures 

 very fine and rather sparse medially, becoming much larger, deep 

 and moderately close-set laterally, the marginal bead very fine ; 

 elytra very nearly one-half longer than wide, more gradually and 

 acutely ogival behind than usual, as wide as the prothorax, virtu- 

 ally smooth but unusually opaque throughout, the sparse punc- 

 tures but slightly evident even laterally; prosternum finely, not 

 densely punctate, the process narrower; abdomen and hind 

 femora finely, more or less sparsely punctate. Length 9.7 mm. ; 

 width 4.25 mm. California. A single female. 



obsolescens n. sp. 



7 — Hind femora finely, more or less sparsely or inconspicuously 



punctate 8 



Hind and other femora coarsely, closely and very conspicuously 

 punctate 13 



8 — Pronotal punctures not particularly close- set laterally, separated 



by from three to five times their own diameters 9 



Pronotal punctures small but deep, unusuall}' close laterally, where 

 they are separated by from one to three times their own diameters ; 

 punctures throughout with extremely short decumbent hairs. ..11
