3o8 Memoirs on the Coleoptera 



feebly arcuate, rather closely punctate and about as long as the pro- 

 thorax, the latter nearly as in umhilicata but with the converging sides 

 more evenly arcuate, not evidently shouldered anteriorly and with the 

 apical constriction obsolescent; scutellum similarly excavated but smaller 

 and less transverse; elytra narrower, two-fifths longer than wide, dis- 

 tinctly wider than the prothorax and nearly twice as long, the sculpture 

 as in umhilicata but with the grooves less coarse; under surface strongly 

 and closely, the abdomen not quite so coarsely, punctate, the male im- 

 pression almost similar. Length (cf 9) 3-I-3-9 mm.; width i. 35-1. 8 

 mm. Pennsylvania (Enola). Two examples. 



Readily distinguishable from umbilicata by its much smaller size 

 and less dilated form, also by the relatively longer beak, this in the 

 male of that species being scarcely more than three-fourths as long 

 as the prothorax, also by the less coarse abdominal punctures. 

 The dimensions of umbilicata, as shown by all the specimens in my 

 collection are 3.8-5.0 by 1.8-2.35 mm. 



Baris irregularis n. sp. — Stout, very convex, deep black throughout 

 and shining, the tarsi not paler; beak in the male closely but rather 

 evenly punctulate, feebly arcuate and rather more than three-fourths as 

 long as the prothorax, the latter with evenly and moderately arcuate 

 upper profile, a fourth or fifth wider than long, the sides slightly con- 

 verging and broadly arcuate, gradually broadly rounding and converging 

 in about apical third, the constriction almost obsolete; punctures not 

 quite so coarse or deep as in umhilicata and unevenly distributed, closely 

 to widely separated, close laterally, the median line similar, the basal 

 lobe much less prominent; scutellum excavated but smaller and less 

 transverse; elytra a fourth longer than wide, much wider than the pro- 

 thorax, throughout almost as in umhilicata, except that the interstitial 

 punctures are not so strong and usually more close-set; under surface 

 with less coarse and more shallow punctures, those of the abdomen 

 medio-basally especially smaller, the impression of the male almost 

 similar. Length (cf) 4-1 mm.; width 2.0 mm. Pennsylvania (locality 

 unrecorded). 



The type differs from the male of umbilicata in the somewhat 

 longer, less coarsely sculptured beak, less coarse and more irregular 

 punctures of the upper surface and in the notably smaller abdominal 

 punctures; the sides of the prothorax are more gradually rounded 

 anteriorly. 



Baris denverensis n. sp. — Rather stout, ovulate and very convex, 

 moderately shining, black, the legs piceo-rufous; beak in the male nearly 

 straight, somewhat closely but not coarsely punctate and only two- 

 thirds as long as the prothorax, the latter with evenly and rather strongly 

 arcuate upper profile, a fifth wider than long, the sides converging and 

 subevenly, feebly arcuate to the abrupt apical constriction, which is
