much smaller and widely separated medially, the impunctate line evident 

 only centrally; scutellum punctate and transverse, obtusely angulate 

 behind; elytra very obtusely subovoidal, slightly wider than the pro- 

 thorax and three-fifths longer, the humeral callus large, moderately 

 prominent; grooves coarse and deep, with small close-set punctures; 

 intervals twice as wide as the grooves to somewhat more, with strong and 

 uneven punctures, confused or in single series, always evidently separ- 

 ated; setae small, even, silvery and evident, with a large loose cluster at 

 the base of the third interval; pygidium opaque, very densely punctate; 

 abdomen rather coarsely and closely but not densely punctate, the 

 medio-basal surface flattened and with finer and denser punctures in the 

 male; femora distinctly punctate, unarmed. Length (cf") 4.5-4.7 mm.; 

 width 2.2-2.5 mm. Kansas (Sylvia). Two examples. 



Allied to farcta Lee, but much less elongate, deep black in color, 

 with smaller scutellum and deeper and less transverse interstitial 

 punctures. 



The two species porcina and farcta differ greatly from the others 

 in habitus, due to their very obese oval form, anteriorly declivous 

 prothorax and greater convexity, allying them more closely with 

 Auloharis; they may take the subgeneric name Pseudobaridia (n. 

 subgen.). 



Pseudobaris lustrans n. sp. — Narrower, suboblong-oval, less convex, 

 polished, deep black throughout; beak strongly arcuate, closely punctate 

 and about as long as the head and prothorax, the latter two-fifths wider 

 than long, with evenly and feebly arcuate upper profile, as usual in the 

 genus, the sides feebly converging and broadly, evenly arcuate from base 

 to the apical constriction, the tubulate apex half as wide as the base, 

 the basal lobe abrupt, prominent and rounded; punctures coarse, deep 

 and close-set throughout, although not in mutual contact, the smooth 

 median line obsolescent anteriad; scutellum short, transverse; elytra 

 two-fifths longer than wide, distinctly wider than the prothorax and 

 almost twice as long, the sides feebly converging and barely arcuate to 

 the broadly obtuse apex, the humeri prominent; grooves deep and rather 

 coarse; intervals about twice as wide as the grooves, with rather strong 

 punctures in even single series and closely or widely spaced or sometimes 

 in part confused; setae very minute and inconspicuous, the cluster at the 

 base of the third interval small and loose; abdomen with rather close- 

 set punctures, not quite so coarse medially, where there is a small sub- 

 basal impression in the apparent male. Length (cf ) 3.8 mm.; width 

 1.65 mm. Pennsylvania (Bethlehem), 



A very distinct species, not closely related to any other thus far 

 described. Sohrina Blatch., which I have from Posey Co., Indiana, 

 and the Black Mts. of North Carolina, is a more narrowly elongate- 

 oval species, having a more conical and more coarsely and densely
