Barin.« 311 



Baris matrona n. sp. — Elongate-suboval, convex, rather shining, red- 

 brown in color, the legs brighter rufous; beak arcuate, finely, basally 

 rather closely punctate, three-fifths as long as the prothorax, the latter 

 large, a fourth wider than long, the sides converging and nearly straight 

 almost to apical fourth, there rapidly rounding, thence strongly con- 

 verging and straight to the apex, the constriction obsolete; punctures 

 rather coarse, deep, close-set, the median smooth line subentire and 

 slightly tumid in the type; basal lobe gradually formed; elytra a third 

 longer than wide, only slightly wider than the prothorax, the callus large 

 and moderately elevated; sides subparallel, the apex broadly rounded; 

 grooves deep, moderate in width; intervals two to three times as wide as 

 the grooves, strongly, loosely and confusedly punctate, unevenly sub- 

 crenulate, those toward the sides with single series of coarse punctures; 

 setae very small; abdomen sparsely, rather finely punctate, densely at 

 apex. Length (9) 4.25 mm.; width 2.0 mm. California (Mokelumne 

 Hill, Calaveras Co.), — Blaisdell. 



There is no species known to me very closely allied to this; its 

 pale color, large prothorax, crenulate striae and red legs will easily 

 distinguish it, 



Baris retrusa n. sp. — Rather narrow, convex, suboval, shining, brown- 

 ish-rufous throughout; beak arcuate, finely, sparsely punctate, two- 

 thirds as long as the prothorax in the female; prothorax only a fifth or 

 sixfh wider than long, the sides feebly arcuate and very slightly con- 

 verging, gradually broadly, evenly rounded anteriorly to the apex, 

 which is not at all constricted; punctures relatively coarse, dense later- 

 ally, rather widely separated but not much less coarse medially, the 

 smooth line narrow from base to beyond the middle; lobe not broadly 

 rounded though gradually formed; elytra two-fifths longer than wide, 

 barely at all wider than the prothorax, the humeri prominent, the sides 

 slightly converging, the apex broadly and rapidly rounded; grooves 

 somewhat coarse, very deep, abrupt, not crenulate; intervals subequal 

 throughout, not quite twice as wide as the grooves, each with an even 

 single series of coarse and rather well separated punctures; setae moder- 

 ate, glistening; abdomen moderately and rather sparsely punctured, 

 with a very feeble basal impression in the male; legs somewhat sparsely 

 punctate, short. Length (cf) 3.35 mm.; width 1.6 mm. Colorado 

 (Canon City), — Wickham. A single example. 



May be known by its rather pale rufous coloration, shining 

 integuments, large and somewhat coarsely punctured prothorax, 

 equal strial intervals and regular loose series of coarse interstitial 

 punctures. 



Baris lavacana n. sp. — Subparallel, narrow, very convex, shining and 

 piceous-black throughout; beak strongly and evenly arcuate, minutely, 

 not densely punctate, barely more than half as long as the prothorax, 

 the latter more than a fourth wider than long, the sides subevenly and
