than the remainder. Length 2.15 mm.; width 1.35 mm. Texas 



(Brownsville), Wickham. A single male.. . integer n. sp. 



Setae two to six or seven in number but more slender and generally hair- 

 like, usually very short 10 



10 Upper surface in great part testaceous in color II 



Upper surface black or piceous-black 15 



n Elytra piceous, each with a large apical and smaller subhumeral 

 testaceous spot, the paler areas very nubilous and not sharply 



defined 12 



Elytra uniform pale brownish-testaceous throughout 13 



12 Body broad, oblong-oval, very convex, testaceous, the pronotum 

 somewhat clouded medially, the elytra piceous, the obliquely oval pos- 

 terior spot generally not attaining the suture, the subhumeral small 

 and remote from the humeral angle; under surface testaceous; head 

 not quite half as wide as the prothorax, extremely minutely, sparsely 

 punctulate; antennae slender, the third joint shorter than the next 

 two, the fourth much shorter than the fifth; club shorter than the 

 funicle; prothorax much more than twice as wide as long, the strongly 

 converging sides evenly and moderately arcuate; base lobed and 

 margined medially; surface very minutely and obsoletely strigilate; 

 scutellum ogival, scarcely wider than long; elytra somewhat longer 

 than wide, much more than twice as long as the prothorax, very 

 obtuse at apex, the sides feebly arcuate; ground sculpture minutely 

 and closely strigilate basally, more coarsely in wavy lines posteriorly 

 and externally and becoming still coarser and more polygonal, the 

 lunules moderate in size, semicircular, those of the intermediate 

 series nearly as large; externally they are but little larger and still 

 in regular series; prosternal process with about three slender bristles, 

 which however are rather long; sterna nearly as in the preceding; 

 second joint of the hind tarsi between three and four times as long 

 as the first, much longer than the remainder and spongiose beneath 

 in the male, more slender and sparsely hairy beneath in the female. 

 Length 1.9-2.0 mm.; width 1.3 mm. California (Fort Yuma). 



Four specimens nebulosus Csy. 



Body smaller and much more narrowly oval than in the preceding, very 

 evenly elliptical in outline, shining, the elytra not quite so opalescent 

 as in nebulosus, pale testaceous; elytra of a slightly darker brown, 

 each with a very large apical and smaller, very indefinite humeral, 

 pallid area; head barely half as wide as the prothorax, very obsoletely 

 strigilate; antennae slender, of the usual type; prothorax only slightly 

 more than twice as wide as long, the rather strongly converging 

 sides evenly and distinctly arcuate; surface minutely, feebly strigilate, 

 the base and the scutellum nearly as in the preceding; elytra 

 very much more finely, closely and evenly strigilate through- 

 out than in nebulosus, with the subsutural impressed stria simi- 

 larly conspicuous, slightly longer than wide, oval and more nar- 

 rowly obtuse at apex, the series of semicircular scratches nearly 

 similar but becoming much broader toward the sides; prosternal 

 hairs few, deciduous and always inconspicuous; anterior margin of 

 the metasternal process more arcuate than usual; post-coxal plaques
