punctured. Legs rather coarsely, deeply, moderately closely punctate ; tarsal 

 claws moderate. Length 3.8-4.0 mm. ; width 1.8 mm. 



Arizona. 



A single pair. In the male the abdomen is strongly impressed 

 in the middle toward base, the impressed area being more finely 

 and sparsely punctured. The prosternum is narrowly but distinctly 

 impressed, coarsely but sparsely punctured, separating the coxae by 

 rather more than one-half of their width. 



24 Baris opacula n. sp. — Elongate-oval, narrow, convex, deep hlack 

 throughout, the legs with a feehle piceous tinge ; lustre dull. Head finely, 

 sparsely, the beak rather finely but deeply, somewhat closely punctate, the 

 latter arcuate, not very robust, three-fourths as long as the prothorax ; an- 

 tennae moderate, normal, first joint of the funicle as long as the next three, 

 club rather robust, ovoidal, pointed, not as long as the scape, the first joint 

 partially pubescent, feebly shining. Prothorax scarcely one-fourth wider than 

 long, the apex subtruncate, nearly one-half as wide as the base ; median lobe 

 of the latter broad and feeble; sides broadly, evenly arcuate throughout, be- 

 coming subparallel in basal third ; disk rather finely but very deeply and 

 densely punctate, without median impunctate area, the punctures not quite 

 one-half as wide as the scutellum and generally separated by less than one- 

 half their width ; interspaces shining. Scutellum small, transverse. Elytra 

 one-half longer than wide, distinctly more than twice as long as the prothorax, 

 at the feebly tumid humeri a little wider than the base of the latter, together 

 rather gradually and strongly rounded behind ; strise rather fine, deep, abrupt, 

 finely, remotely punctate, not crenulate except feebly toward base ; intervals 

 wide, flat, minutely, strongly granulate, dull, each with a single series of fine, 

 moderately distinct punctures, confused on the second and third intervals ; 

 setae very minute, not at all conspicuous. Abdomen polished, convex, rather 

 sparsely punctate, the last segment densely so. Legs moderate, finely, sparsely 

 punctate ; tibia? straight externally. Length 4.0-4.7 mm. ; width 1.65-2.1 mm. 



California. 



The prosternum is coarsely, somewhat closely punctate and very 

 feebly impressed, and the coxae are separated by one-half their 

 width. 



This is one of the most isolated species of the genus, easily identi- 

 fiable by the opaque elytra, fine deep strise and dense pronotal punc- 

 tures. 



25 Boris porosicollis n. sp. — Not very robust, convex, oval, deep 

 black throughout, not strongly shining. Head finely, sparsely punctate, 

 separated from the beak by a wide but distinct, obtusely angulate depression ; 

 beak rather arcuate, two-thirds as long as the prothorax, finely, closely punc- 

 tate, more closely and very densely so at the sides ; antennae moderate, the
