Baring 325 



long as the prothorax (9 ) ; the latter with the upper line evenly arcuate 

 in profile, almost a fourth wider than long, feebly inflated near the 

 base, the nearly straight sides gradually rounding before the middle, 

 the apex very briefly subconstricted; punctures moderate but deep, 

 distinctly separated, becoming dense laterally, the median smooth line 

 evident, except toward base and apex; scutellum very small, impressed; 

 elytra not quite one-half longer than wide, slightly wider than the pro- 

 thorax and about twice as long, subparallel, gradually rounding behind, 

 the humeral callus rather notably prominent; grooves somewhat narrow, 

 deep, finely and very indistinctly subcrenulate; intervals between three 

 and four times as wide as the striae, with uneven loose series of minute 

 and almost indistinct punctures; abdomen distinctly but shallowly, 

 loosely punctate. Length (9) 4-25 mm.; width 1.6 mm. California 

 (south of San Francisco), — Dunn. One example. 



Allied evidently to the last but smaller and much narrower, with 

 a more loosely punctate prothorax and with the elytral grooves 

 narrower and much less crenulate, though decidedly coarser than 

 in teniiestriata; in the female type the strial intervals are distinctly 

 convex and the interstitial punctures very minute and indistinct. 



Baris crenulita n. sp. — Larger and stouter, somewhat shorter and 

 broader than in instans, much larger and broader than in tenuestriata, 

 deep black throughout and shining; beak in the male thick, feebly 

 arcuate, densely punctate and three-fourths as long as the prothorax, the 

 upper line of which is subevenly arcuate in profile; prothorax unusually 

 short and transverse though scarcely one-half wider than long, the sides 

 subparallel, slightly arcuate, rounding and rapidly converging anteriorly, 

 the apical constriction subobsolete; basal lobe small and feeble; punc- 

 tures rather coarse, dense, a little smaller and slightly separated medially, 

 the smooth median line evident but abbreviated; scutellum very small, 

 rounded, impressed; elytra long, rather more than one-half longer than 

 wide, just visibly wider than the prothorax and a litde more than twice 

 as long, the feebly converging sides slightly arcuate, the apex obtuse, 

 the humeral callus distinctly prominent and polished; grooves moderate, 

 deep, minutely but strongly although somewhat distantly crenulate; 

 intervals fiat, three or four times as wide as the grooves, with single 

 lines of very small and well separated punctures, the setae minute; 

 abdomen rather coarsely but loosely punctate, with a feeble concavity 

 at base in the male, extending slighdy upon the second segment; py- 

 gidium densely punctate, convex inferiorly. Length (cf) 4-8 mm.; 

 width 1.9 mm. California (San Diego Co.). One example. 



The type of this species represents one of the allies o{. tenuestriata, 

 but is very distinct in the short, broad and cribrate prothorax and 

 long elytra, with sharply crenate striae, which are much less coarse 

 than in laxicollis but twice as wide as in tenuestriata.
