Baring 309 



deep and distinct, the apex tubuliform; punctures and basal lobe nearly 

 as in umbilicata, the former less coarse and closer, separated by scarcely a 

 third their diameters, the median smooth line much shorter and merely 

 central; scutellum slightly transverse, deeply impressed; elytra two- 

 fifths longer than wide, much wider than the prothorax and four-fifths 

 longer, the outline and sculpture as in umbilicata, except that the uni- 

 seriate interstitial punctures are still coarser; abdominal punctures 

 similarly strong and close, the male impression similar but longer, ex- 

 tending more than half way through the second segment. Length (cf ) 

 3.8 mm.; width 1.75 mm. Colorado (Denver). 



This species differs from umbilicata in its more slender, less 

 coarsely sculptured beak, apically more constricted prothorax, with 

 the punctures not quite so coarse and still more close-set, in the 

 slightly coarser interstitial punctures and rufescent legs. 



Baris genitiva n. sp. — Rather narrowly oval, strongly convex, shining, 

 black throughout; beak in the male notably slender, slightly arcuate, 

 rather finely, sparsely punctate, two-thirds as long as the prothorax, 

 which is a fourth wider than long, with the sides moderately converging 

 and slightly arcuate, rapidly rounding in apical fourth to the apex, which 

 is very briefly subtubulate; punctures coarse, deep, rather well separated, 

 minute at apex, closer but not confluent at the sides, the smooth median 

 line greatly biabbreviated; basal lobe large, broadly rounded, the scutel- 

 lum small, slightly transverse, impressed and emarginate; elytra two- 

 fifths longer than wide, throughout nearly as in umhilicata, except that 

 the punctures of the regular single interstitial lines are not quite so 

 coarse; abdomen with the punctures similarly coarse but not so dense, 

 the basal impression of the male smaller and much feebler. Length (cf) 

 3.5 mm.; width 1.5 mm. Florida (locality unrecorded). 



Allied to umhilicata but differing in its smaller size and narrower 

 outline, rather shorter, much more slender and more sparsely 

 punctate beak, relatively somewhat smaller though otherwise 

 nearly similar prothorax, less coarse interstitial punctures and 

 sparser abdominal punctures, with feebler basal impression in the 

 male; the slenderness and sparse sculpture of the beak are char- 

 acters apparently decisive in the separation of this form as a species. 



The following thirteen species belong to the group comprising 

 subcenea, floridensis, rubripes, aprica, vespertina, dolosa and penin- 

 sulcB, the last of which was described from Lower California by 

 Horn. They resemble inter stitialis rather closely but are all of a 

 piceous or obscure reddish color. All of those here described, 

 excepting oblata and surrufa, occur only in the very broken extreme 

 western country.
