634 Coleopterological Notices, IV. 



as long as the next two ; club rather small but abrupt, densely 

 pubescent throughout, and with the basal joint constituting a little 

 more than one-half the mass. Prothorax about as long as wide, 

 the sides parallel and broadly, evenly arcuate to near apical fifth, 

 then convergent and distinctly constricted to the apex, which is 

 scarcely more than one-half as wide as the base; disk rather finely 

 but deeply, somewhat unevenly and not very densely punctate, the 

 median line narrow. Scutellum small, glabrous, quadrate, the 

 posterior angles rather prominent. Elytra slightly wider and four- 

 fifths longer than the prothorax, bemi-elliptical, evenly, rather 

 narrowly but not acutely rounded behind, the humeri feeble; disk 

 with rather coarse but moderately deep striae, the intervals nearly 

 twice as wide as the grooves, flat, each with a single series of gene- 

 rally small but deep, not very close-set punctures, which vary 

 greatly in size, more or less broadly confused toward the base 

 of the third. Abdomen polished, rather finely, not very densely 

 punctured. Prosternum flat, separating the coxae by more than 

 their own width, the punctures not conspicuously coarse. Length 

 3.7-4.4 mm. ; width 1.35-1.75 mm. 



California (San Francisco) and Texas (El Paso). Numerous 

 specimens. The male does not differ from the female by any struc- 

 tural peculiarities of note. 



10 Liimno'baris Olblita n. sp. — Elongate-oval, moderately convex, 

 strongly shining, the elytra minutely granulato-reticulate and slightly aluta- 

 ceous, hlack throughout, the legs and antenna? with a piceous tinge, sub- 

 glabrous, the vestiture excessively sparse throughout, the setae very small 

 and inconspicuous. Head minutely but strongly, sparsely punctate, the 

 impression quite distinct; beak slender, cylindrical, evenly, rather feebly 

 arcuate, shining, finely, linearly and not very densely punctate, with two or 

 three bristling squamules at the upper border of the eyes, about as long as 

 the head and prothorax ; antennas inserted just beyond the middle, the basal 

 joint of the funicle nearly as long as the next four, second barely one-half 

 longer than the third, club oval, nearly as long as the five preceding joints 

 combined, the basal joint composing three-fifths of the mass and sparsely 

 pubescent toward base. Prothorax slightly wider than long, the sides just 

 visibly convergent, evenly and feebly arcuate from the base to the constric- 

 tion, the latter rather deep and abrupt and situated at a somewhat unusually 

 great distance behind the apex, the latter broadly sinuate in the middle, one- 

 half as wide as the base, which is transverse and almost perfectly straight 

 throughout ; disk not very coarsely but deeply, somewhat closely punctate, 

 the punctures rather unevenly distributed, a median line not extending to 

 the apex and a wide apical margin entirely impunctate. Scutellum small, 

 fiat, polished, triangular, widest and truncate behind. Elytra quite distinctly
