Barin.e 303 



broadly, subequally arcuate, becoming gradually parallel basally, the 

 apical constriction very short; punctures coarse, deep, usually separated 

 by half their diameters, the distinct impunctate line not attaining base 

 or apex; scutellum small, moderately impressed; elytra barely a third 

 longer than wide, a fourth or fifth wider than the prothorax, subparabolic 

 from the humeri around the apex; grooves coarse and deep, moderately 

 punctured at the bottom; intervals not distinctly wider than the grooves, 

 the second and third wider and closely, strongly punctate but not sulcate, 

 the narrower intervals sulcate, the punctures moderate but very close, 

 each with an erect bristling seta, longer than in the other species; ab- 

 domen with distinct lustrous pale setae, rather strongly, somewhat closely 

 punctate in the male, with a large impression extending almost to the 

 end of the second segment and rather acutely defined along the bottom 

 on the first segment. Length (cf ) 5.1 mm.; width 2.4 mm. Montana. 

 A single example. 



Differs from montanica in its shorter, stouter form, relatively 

 more inflated elytra, almost similarly coarse but looser pronotal 

 punctures, with more polished interstices and relatively narrower 

 strial intervals, which are coarsely and deeply sulcate. 



*Baris agricola n. sp. — Form, size, coloration and lustre very nearly as 

 in transversa (strenua), but a trifle narrower and more elongate, the beak 

 similar but still more coarsely and densely punctate; prothorax large 

 and of similar form, a fourth wider than long, the feebly converging sides 

 gradually rounded anteriorly, the very short tubulation more definite; 

 punctures very deep, a little coarser and still closer, more crowded, the 

 partial smooth median line narrow and inconspicuous; scutellum short, 

 transverse, deeply impressed; elytra a little less than one-half longer 

 than wide, a fifth wider than the prothorax and three-fourths longer; 

 grooves deep and coarse, punctate at the bottom, the intervals not wider 

 than the grooves, excepting as a rule the slightly wider and confusedly 

 punctate second and third, each of the narrow intervals with a more or 

 less impressed series of close-set coarse punctures, about two-thirds as 

 wide as the intervals, the punctures bearing small silvery-gray setae; 

 abdomen with close and rather coarse, deep punctures, the male with a 

 deep basal concavity gradually disappearing on the second segment; 

 pygidium convex, with rather coarse, close punctures. Length (cf 9 ) 

 4.8-6.0 mm.; width 2.2-2.7 mm. Mexico (Aguas Calientes, Ags.), — 

 Wickham. Three examples. 



A large species coming near transversa, but differing in the de- 

 cidedly coarser and still closer punctures, more conspicuous basal 

 impression of the abdomen, rather more convex pygidium and 

 slightly less inflated form of the body. The Yucatan championina 

 is smaller and shorter, with more rounded thoracic sides and much 

 less closely placed coarse punctures.
