334 Memoirs on the Coleoptera 



more closely sculptured than socialis and generally has a very faint 

 aeneous lustre, wholly wanting in the blacker and more shining, 

 more elongate-oval socialis; ancilla Csy., from Tampa, Florida, 

 is allied rather closely to socialis, resembling it almost exactly in 

 outline and size, but the pronotal punctures are smaller, the serial 

 punctures of the elytra much more minute and more widely separ- 

 ated, and the beak is longer and notably heavier. The following 

 four species are more or less closely allied to ancilla and socialis, 

 though carolinensis is closer to confinis, being similarly rather 

 closely sculptured and less elongate than the others, but it is 

 smaller and narrower than confinis: 



Baris neptis n. sp. — Rather broadly oval, convex, deep black, polished, 

 without trace of metallic lustre; beak in the male rather slender, arcuate, 

 finely, loosely punctate and barely three-fifths as long as the prothorax, 

 the latter two-fifths wider than long, the sides slightly converging and 

 feebly arcuate, rapidly rounding and very strongly converging in about 

 apical fourth, the basal lobe short; punctures moderate though deep, 

 separated by their own widths or more and very small medio-apically, 

 gradually coarser and closer though barely contiguous at the sides, the 

 median smooth line subobsolete; scutellum very small, rounded, emar- 

 ginate behind; elytra two-fifths longer than wide, rather evidently wider 

 than the prothorax and about twice as long, the sides slightly converging 

 and broadly arcuate, the apex moderately obtuse, the humeri somewhat 

 prominent; grooves rather coarse, deep, somewhat crenulate basally; 

 intervals one-half wider than the grooves, each with a single series of 

 fine and moderately separated punctures, the second and third wider, 

 more unevenly uniseriate; setae minute; abdomen with rather coarse, 

 deep and close-set punctures, having (cf ) a feeble medio-basal con- 

 cavity, gradually evanescent on the second segment. Length (cT) 3.3 

 mm.; width 1.4 mm. North Carolina (Asheville). 



Notably broader than socialis and with coarser and much closer 

 abdominal punctures. 



Bails metasternalis n. sp. — Form rather narrowly elongate-oval, more 

 strongly convex, polished, deep black, without metallic lustre; beak 

 rather slender, feebly arcuate, finely, loosely punctate and about two- 

 thirds as long as the prothorax, the latter only a fifth wider than long, 

 the converging sides feebly arcuate, gradually rounding and more con- 

 vergent in about apical fourth; basal lobe rather small and feeble; 

 punctures strong though only moderately coarse, tvell separated, longi- 

 tudinally subconfluent at the sides, the median smooth line narrow and 

 not strongly defined; scutellum minute, rounded, impressed; elytra a 

 little more than two-fifths longer than wide, slightly wider than the 

 prothorax and not quite twice as long, the sides feebly converging and 

 broadly arcuate, the apex obtuse, the humeri moderately prominent;
