CETONIIISLE 355 



wide, only a fifth or sixth wider than the prothorax, rarely having 

 each a small broken transverse spot of tomentum at the side behind 

 the middle; pygidium moderately convex, with rather large close-set 

 deep opaque areolae of circular to polygonal outline; sterna, femora 

 and sides of the abdomen with coarse deep opaque foveolae, densely 

 crowded on the met-episterna, the sparse erect hairs extremely 

 short; two anterior tibial teeth acute and well developed. Length 

 11.4-13.0 mm.; width 5.2-6.0 mm. California (San Francisco). 

 Abundant maritimus n. sp. 



Hind tarsi much shorter than the tibiae in both sexes, generally distinctly 

 and sometimes very strongly compressed 14 



14 Pronotum peculiarly sculptured, the punctures large, shallow, very 

 densely opaque and extremely densely crowded, those of the head 

 of the same character but not so coarse; each puncture has the minute 

 puncture at its apex, bearing the erect hair, very distinct. Body 

 rather elongate, black, the elytra slightly, the under surface strongly, 

 shining; erect hairs extremely small, very coarse and fulvous; head 

 nearly flat above, rather abruptly declivous anteriorly, the upper 

 limit of the slope slightly and very obtusely tumid laterally; clypeus 

 very strongly reflexed, as wide as the head as usual; prothorax fully 

 one-half wider than long, the sides parallel, subevenly and strongly 

 arcuate from the extreme basal to the apical tips of the angles, rather 

 more converging apically than basally, the apical angles unusually 

 oblique along the cavities, the basal acute at tip but much thickened, 

 the outer aspect being rather broadly convex; transversely, they are 

 separated from the median parts of the base, which is punctureless 

 as usual, by a rather deep, evenly rounded sinus; scutellum with very 

 shallow areolae, the median line finely callous posteriorly; elytra very 

 feebly cuneiform, one-half longer than wide, rather more than a 

 fourth wider than the prothorax, very flat and with large, elongate- 

 oval and very shallow opaque areolae on the disk, rather abruptly 

 vertical and more strongly and closely but less coarsely punctate at 

 the sides; pygidium with large, very opaque and dense areolse, 

 smooth and sparsely punctulate at apex; hind tarsi two-thirds as 

 long as the tibiae, only moderately compressed and scarcely at all 

 tapering, the last joint nearly one-half longer than the fourth. 

 Length 12.0 mm.; width 5.4 mm. California (Humboldt Co.). 

 A single example densicollis n. sp. 



Pronotum with better defined, more discrete and generally deeper punc- 

 tuation as in angularis 15 



15 Pronotum with a broad oblique area at each side, from near the 

 apical angles to each side at base, in which the punctures are nearly 

 wanting and coarser than those of the remainder of the surface; 

 elytra with larger and smaller foveolae intermingled. Body rather 

 narrow, deep black, slightly shining above, polished beneath; erect 

 hairs very small, sparse, coarse; head with dense larger and smaller 

 punctures intermingled, flat above, the apical slope rather abrupt, 

 its upper limit only feebly tumid at the sides however, the very 

 strongly reflexed clypeus broadly sinuate medially; prothorax 

 scarcely one-half wider than long, the parallel sides only feebly
