deep, impressed, separated by very nearly their own diameters; 

 abdomen shining, the punctures laterally very large, moderately 

 separated, becoming notably smaller and separated by twice their 

 widths medially, the last segment closely cribrate throughout; sul- 

 cate prosternum with fine punctures, separated by more than three 

 times their widths; hypomera deeply concave toward the inner angle. 

 Length 1.65 mm.; width 0.8 mm. California (Gilroy Hot Springs, 

 Sta. Clara Co. 1 ). [L. ( Li mni chiles) perforatus Csy., Ann. X. Y. 

 Acad., 1890. p. 155] perforatus Csy. 



Oblong-oval, in color, form and general sculpture nearly as in the pre- 

 ceding but a little broader, the vestiture somewhat longer and closer, 

 less definitely mottled and more cinereous; head strongly, densely 

 punctate, the punctures anteriorly not obliquely coalescent; pro- 

 thorax with the punctures medially rather less fine than in per- 

 foratus but otherwise similar, separated by twice their widths, 

 somewhat smaller but quite as sparse in a more flattened median 

 basal area which is limited anteriorly by two rather distinct lines 

 obliquely approaching the fine impressed median line and uniting 

 therewith just beyond its middle point as in perforatus, the punctures 

 laterally materially coarser and denser, separated by less than half 

 their widths; scutellum as usual, slightly longer than wide, ogival and 

 punctured like the adjoining part of the pronotum; elytra coarsely, 

 very deeply impresso-punctate, the punctures separated by rather 

 less than their own diameters; abdomen less shining than in the 

 preceding, strongly and much more closely punctate throughout and 

 more closely clothed with dark cinereous pubescence, the punctures 

 medially not much finer than at the sides and separated by only 

 about half their widths; on the sulcate prosternum stronger than in 

 perforatus and separated by twice their own diameters. Length 

 1.6 mm.; width 0.85 mm. Texas (Columbus), .foraminosus n. sp. 



6 Larger than the preceding, more evenly oval, obtuse behind, the apex 

 feebly and narrowly lobed, shining, black, the short decumbent 

 hairs very coarse and conspicuous, pale fulvous, indefinitely mottled 

 with cinereous on the elytra; head not very coarsely punctate, the 

 punctures separated, becoming closely crowded only anteriorly; 

 prothorax rather less transverse though evidently more than twice 

 as wide as long, the rather more converging sides feebly and evenly 

 arcuate, the surface with a transversely subarcuate series of tu- 

 mescent punctures medially, only behind which is the median line 

 impressed, the general punctures, fine, separated by two or three 

 times their widths, becoming laterally only slightly larger and still 

 separated by nearly twice their diameters; scutellum finely, sparsely 

 punctate, subimpunctate about its ogival contour; elytra a fourth 

 longer than wide, the sides broadly rounded basally, beginning to 

 converge very slightly from near basal fourth, gradually more 

 rounded posteriorly, the punctures small, not so deep as usual and 

 separated by more than twice their diameters; abdomen closely, 

 rather strongly cribrate, the punctures medially toward base be- 

 coming fine and separated by twice their widths, the punctures of 

 the sulcate prosternum coarser and deeper but similarly separated
