joints, oval. Prothorax about as long as wide, the sides very feebly con- 

 vergent and straight from before the base to apical third, then gradually a 

 little more convergent to the apex, which is four-fifths as wide as the base; 

 constriction fine and feeble ; disk rather coarsely, very deeply and somewhat 

 unevenly punctate, the punctures separated by about their own diameters, 

 without impunotate line. Elytra short, just visibly wider and barely two- 

 thirds longer than tlie prothorax, one-half longer than wide ; sides parallel 

 and straight, the apex semi-circularly rounded ; disk with coarse, rather 

 deep, coarsely and profoundly punctate stripe, the intervals narrow but 

 nearly flat, scarcely more than one-half as wide as the strise, each with a 

 single series of fine remote punctures. Under surface densely punctate, the 

 abdomen more sparsely so, the fifth segment closely. Anterior coxse large, 

 separated by rather less than one-third of their own width. Length 3.0 mm. ; 

 width 1.05 mm. 



California. 



The type to which this isohited species is referable, differs from 

 that of pallens and spretus very greatly in the antennal scrobes, 

 which, in those species, are basal and nearly transverse ; in dila- 

 tatus they begin near the apex of the somewhat longer beak, de- 

 scending thence obliquely beneath the eye ; the scape, also, is 

 gradually and evenly clavate in dilatatus, and not swollen in the 

 middle beneath, and the head is shorter with the eyes less remote 

 from the prothorax. The first ventral suture is deep and straight, 

 the next two extremely coarsely excavated but straight. One 

 specimen. 



R. relictllS n. sp. — Ovo-cylindrical, dark piceous-brown, the tarsi and 

 antennal club paler. Head very minutely, sparsely, the beak more strongly, 

 rather densely, punctate, the latter as long as the head, nearly as long as 

 wide, parallel and straight at the sides and distinctly impressed along the 

 middle ; eyes situated neai-ly midway between the prothorax and tip of the 

 beak ; antennae moderately long, the scrobes narrow, obliquely descending, 

 scape gradually thick and clavate, inserted at basal third, distinctly shorter 

 than the funicle, the latter rather slender, the second joint longer than the 

 third, outer joints thicker, club distinctly wider, oval. Prothorax one-third 

 longer than the head and beak, fully as long as wide, widest at basal third 

 where the sides are broadly arcuate, thence feebly convergent and nearly 

 straight to the apex, which is just visibly narrower than the basal margin ; 

 constriction feeble ; disk finely, not very deeply, somewhat unevenly and not 

 densely punctate, generally with a feebly defined median impunctate spot. 

 Elytra one-fifth wider than the prothorax and fully twice as long, not quite 

 twice as long as wide ; sides straight and parallel, convergent and constricted 

 in apical third, the apex somewhat produced and narrowly, almost seuii-circu- 

 larly rounded ; disk with impressed series of rather large, very deep, well- 

 separated punctures, the intervals feebly convex, barely one-half wider than
