fourths of their width, the process being unusually wide. , The 

 species is especially notable by reason of its coarsish punctuation, 

 long prothorax and rather short subcorneal elytra. 



21 Baris aprica n. sp. — Oblong-oval, strongly convex, polished and 

 dark piceous-brown throughout, the setae small, distinct but not conspicuous. 

 Head excessively minutely and sparsely punctulate, the transverse impression 

 strong and angulate ; beak very short, thick, moderately arcuate, feebly flat- 

 tened toward apex, densely but not coarsely punctate and about two-thirds 

 as long as the prothorax ; antennal scape very short, the club rather robust, 

 oval, with the basal joint polished but sparsely pubescent and constituting a 

 little less than one-half the mass. Prothorax one-third wider than long, the 

 sides broadly rounded and strongly convergent anteriorly, becoming almost 

 parallel and straight in basal two-thirds ; base straight and feebly oblique at 

 the sides, the lobe equalling nearly one-third of the width, rather prominent ; 

 disk coarsely deeply and densely punctate, the punctures very narrowly sepa- 

 rated, a narrow impunctate line distinct but not attaining the apex. Scutel- 

 lum moderate, subquadrate, rugose. Elytra but slightly wider and three- 

 fourths longer than the prothorax, the sides behind the scarcely prominent 

 humeri just visibly convergent ; apex abruptly and obtusely rounded, the 

 sutural notch broad and deep ; stria? rather coarse, deep, the intervals but 

 slightly wider than the grooves, each with a single series of large, very deep, 

 even and almost contiguous punctures, the third much wider than the others 

 and with the punctures broadly confused and smaller. Abdomen strongly but 

 not coarsely, moderately closely punctured. Presternum flat, densely punc- 

 tate, separating the coxse by rather more than one-half of their own width. 

 Length 3.4^3.6 mm. ; width 1.65-1.7 mm.

The coarse deep rounded and close-set punctures, forming a single 

 series on each of the elytral intervals, is a type of sculpture w T hich 

 forcibly reminds us of several species of Onychobaris, such as 

 stictica, but otherwise there is no resemblance. Aprica belongs in 

 the group containing transversa, but is not very closely related to 

 any other species. The abdomen in the male has a rather small but 

 distinct subbasal impression. 



22 Baris dolosa n. sp. — Oblong-oval, strongly convex, piceous-black 

 throughout, polished, the elytra frequently feebly piceous. Head obsoletely, 

 the beak finely, sparsely punctured, the latter quite coarsely and closely so at 

 the sides, thick and arcuate toward base, straight and somewhat tapering in 

 apical half, two- thirds (£>) to three-fourths ( J ) as long as the prothorax; 

 antennae moderate, normal. Prothorax nearly two-fifths wider than leng, the 

 sides nearly parallel and very feebly arcuate to apical fourth, then strongly 

 but moderately narrowly rounded, thence very strongly convergent and nearly 

 straight to the apex ; base three times as wide as the head, subtransverse and
