304 Memoirs on the Coleoptera 



Baris humerosa n. sp. — Body large, elongate, convex, deep black and 

 moderately shining; beak arcuate, nearly four-fifths as long as the pro- 

 thorax and strongly, rather closely punctate; prothorax large, nearly a 

 third wider than long, the sides almost parallel, very rapidly rounded 

 anteriorly to the distinctly tubuliform apex; basal lobe distinct, rounded; 

 punctures coarse, separated by about a third of their diameters, dense 

 laterally but not forming distinct lines; median smooth line short but 

 evident; elytra two-fifths longer than wide, nearly a fourth wider than 

 the prothorax and almost four-fifths longer; grooves coarse, moderately 

 punctate; intervals all evidently wider than the grooves, flat, not at all 

 sulcate, the punctures of the single series well separated, deep, slightly 

 more than a third as wide as the intervals and bearing very small pale 

 setae; only the third interval is wider than the others and with more 

 confused median series; pygidium densely punctate and with longer pale 

 hairs; abdomen strongly but not very densely though closely punctate. 

 Length (9) 6.0 mm.; width 2.75 mm. Illinois. A single example. 



In this species the prothorax has the same pecuHarly shouldered 

 form as in gravida, a still larger and stouter species of western Texas; 

 the thoracic punctures are, however, much coarser and those of the 

 strial intervals relatively somewhat smaller and less confused, the 

 intervals being narrower, and the beak is more arcuate, both types 

 being the female. In humerosa the apical tubulation of the pro- 

 thorax is much more developed ; the outline is more elongate than 

 in transversa and the sculpture coarser. 



Baris satelles n. sp. — Form short, stout and convex, subparallel, deep 

 black, not very shining; beak only feebly arcuate, very nearly as long 

 as the prothorax, strongly and densely punctate; antennae rather short; 

 prothorax about a fourth wider than long, the sides subparallel, gradually 

 broadly rounding anteriorly to the very short and feeble constriction; 

 basal lobe distinct, not broadly rounded; punctures moderately coarse, 

 very dense throughout, forming partial lines, the median impunctate 

 line narrow, partial and feeble; elytra short, a fourth longer than wide, 

 a fifth or sixth wider than the prothorax and about three-fourths longer, 

 parallel, rapidly very obtusely rounded at apex; grooves not very deep, 

 closely punctate; intervals throughout a little wider than the grooves, 

 the punctures very close, relatively rather coarse and forming impressed 

 sulci, the setae very short, pale; abdomen not very coarsely but densely 

 punctate, the male with a moderate impression confined to the first 

 segment; pygidium closely but discretely punctate. Length (cf ) 3-9 

 mm.; width 2.0 mm. New Mexico (Jemez Springs), — Woodgate. 



A very distinct species belonging to the transversa group but very 

 much smaller and relatively even stouter than that species, with 

 evidently less coarse and denser punctures. 



Baris formalis n. sp. — Somewhat as in transversa but smaller and 

 much narrower, black, the pronotum shining, the elytra less so, black,
