Baring 363 



punctured prothorax, also coarser, much more close-set and more 

 even interstitial punctuation; the abdomen in sobrina is much 

 more coarsely and densely punctate; the beak in both these species 

 is very evenly arcuate above from apex to the frontal impression, 

 in sharp contrast with the following: 



Pseudobaris gibbirostris n. sp. — Slightly narrower than the preceding 

 and somewhat smaller, rather more convex, deep black throughout and 

 shining, similarly non-metallic; beak in the female rather slender, some- 

 what longer than the head and prothorax, closely and rugosely punctured 

 at the sides basally, elsewhere almost smooth, evenly arcuate, the upper 

 surface tumid at base in front of the transverse impression; prothorax 

 shorter, one-half wider than long, the sides subparallel and arcuate, more 

 rapidly rounding and strongly converging in somewhat less than apical 

 half, the briefly tubulate apex half as wide as the base, which becomes 

 gradually oblique inwardly to the tip of the moderately prominent lobe; 

 punctures deep and coarse, slightly less so medially, well separated, 

 close-set at the sides, the impunctate line only central; scutellum slightly 

 transverse, angulate behind; elytra two-fifths longer than wide, only a 

 little wider than the prothorax and about four-fifths longer, obtusely 

 ovoidal in form, the humeri only moderately prominent; grooves deep, 

 very coarse, a little less so posteriorly; second and third intervals fully 

 twice as wide as the grooves, the others less, the interstitial series com- 

 posed of rather coarse but not very deep, separated, sometimes sub- 

 transverse and often somewhat confused punctures; setae indistinct, the 

 cluster at the base of the third interval moderate; abdomen loosely and 

 rather finely punctate, more strongly and less loosely toward the sides; 

 femora as in sobrina, less deeply emarginate beneath than in lustrans. 

 Length (9) 3.65 mm.; width 1.45 mm. Florida (locality unrecorded). 



This species, also very distinct, may follow the preceding and 

 sobrina in the lists. I am uncertain whether or not the rostral 

 swelling may be variable or to some extent sexual. 



The following five species are from the mountainous regions of 

 Colorado to the coastal regions of the Pacific, and, as species, are 

 remarkably local; this will serve as an efficient index in identifying 

 them ; all except oscitans have at least traces of remotely scattered 

 longer pale setse on the elytra. 



Pseudobaris oscitans n. sp. — Elongate, subcylindric-oval and convex, 

 rather shining and deep black throughout; beak in the female arcuate, 

 rather slender, feeblj^ punctulate, strongly latero-basally and scarcely as 

 long as the head and prothorax; the latter is not quite a third wider 

 than long, the sides subparallel and feebly arcuate, gradually broadly 

 and moderately rounded and converging in about apical third, the feebly 

 subtubulate apex half as wide as the base, the median lobe of which is 

 rather small, abrupt but short and broadly rounded; punctures deep but
