deeply and rather closely punctured toward base. Length 3.2-3.7 

 mm.; width 1.4-1.75 mm. 



The series before me was collected by Mr. G. W. Dunn, at Saa 

 Diego, California, from which locality it was originally described. 



Mr. H. C. Fall of Pomona, Cal., writes me that this si)ecies is 

 found at Coronado, immediately opposite San Diego on the line of 

 the seabeach, where it " frequents the flowers of a low Seshy-leaved 

 plant just above the beach." Mr. Fall states further that he has 

 " taken it in the flowers in July and in the sand beneath the plants 

 in February," and also remarks that in every specimen taken by 

 him "the legs, and beak to some extent, incline to paleness." It 

 may be concluded from these statements that derisa is confined in 

 distribution to the immediate seashore of Southern California. 



2 OliycllOl>aris COrrosa n. sp. — Oblong-oval, convex, black, the head, 

 beak and legs piceous ; integuments opaque from extreme density of sculp- 

 ture. Head finely but strongly, densely punctured for a short distance behind 

 the transverse polished and impunctate interocular impression, whicli is 

 normally feeble ; beak thick, not sensibly tapering, rather strongly, evenly 

 arcuate, very densely punctate, the fine median impunctate line obliterated 

 toward base, equal in length to the prothorax ; antennae moderate, the second 

 funicular joint fully one-half longer than the third. Prothorax about one- 

 third wider than long, the sides straight and parallel in basal two-thirds, then 

 broadly rounded and convergent to the apex, which is only feebly constricted ; 

 base broadly bisinuate, the median lobe more prominent than the sides, rather 

 narrowly rounded at apex and broadly cuspiform ; disk without distinct trace 

 of median line, the punctures moderately small, fully one-third as wide as 

 the scutellum, deep and throughout extremely dense and polygonally crowded. 

 Scutellum rather small, transverse. Elytra slightly longer than wide, nearly 

 three-fourths longer than the prothorax, and, at the feebly prominent humeri, 

 slightly wider than the latter ; outline behind the humeri evenly hemi-ellipti- 

 cal ; disk with rather coarse deep grooves, the intervals nearly flat, subequal, 

 about one-half wider than the grooves and rather coarsely, deeply, extremely 

 densely and confusedly punctate throughout, somewhat coarsely rugulose, 

 the setae distinct but sparse, short, subrecumbent and rather robust, those at 

 the bottom of the grooves as large and distinct as the others. Abdomen finely, 

 rather closely punctured. Length 3.9 mm. ; width 1.8 mm. 



Colorado. 



The unique type is apparently a female, and the species is quite 

 distinct from any other here noted. 



3 OnycIlObaris depressa n. sp. — Oblong-oval, depressed, black, the 

 legs rufopiceous ; setae rather short but erect and hispid, broad and sub- 

 squamiform, abundant, cinereous and conspicuous. Head coarsely, very
