the strije, each with an uneven series of extremely minute distant punctures. 

 Under surface not very coarsely but deeply and densely punctate, the abdo- 

 men more sparsely so except on the fifth segment ; first suture very fine, 

 broadly curved throughout and just traceable, the other three very coarse 

 and deep anterior coxae separated by barely one-third of their own width. 

 Length 2.8-3.4 mm. ; width 0.8-1.1 mm. 



New Mexico. 



This species shares to some extent the characters distinguishing 

 both the pallens and oregonensis types of the genus, having the 

 somewhat longer uncontractile second funicular joint and the oval 

 and wider club of the former, and the fine and feeble first abdo- 

 minal suture of the latter. In oregonensis the club is but very 

 slightly wider than the tip of the funicle, and the eyes are larger, 

 more circular and decidedly nearer the apex of the prothorax. The 

 beak in relictus is somewhat aberrant in being parallel and not 

 conical. 



R. Iliinius n. sp. — Cylindrical, moderately stout, polished, black through- 

 out, the tarsi and antennal club paler. Head very minutely and sparsely 

 punctate, the beak more coarsely deeply and rather densely so, just visibly 

 and unevenly subimpressed along the middle, conical, about as long as the 

 head and nearly as long as wide ; eyes rather large, very convex, finely 

 faceted as usual, situated at a little more than their own length from the 

 prothorax ; antennje short and very thick, aberrant, inserted at basal third, 

 scrobes deep and coarse, beginning at apical third and rapidly obliquely de- 

 scending, scape short, thick, the funicle very thick, cylindrical and equal in 

 diameter from the second joint to the widest part of the club, the basal joint 

 a little thicker, wider than long, with its apex excavated, the second joint 

 deeply received in the cup-like excavation and having only a very short 

 apical margin exposed beyond it ; joints two to seven short, extremely trans- 

 verse but somewhat compactly perfoliate, each joint being deeply concave at 

 apex ; club not in the least wider, scarcely longer than the three preceding 

 joints combined. Prothorax a little longer than wide, the sides broadly, 

 almost evenly arcuate, gradually convergent anteriorly, the constriction dis- 

 tinct ; apex broadly arcuate and a little narrower than the base ; disk 

 coarsely, deeply but rather sparsely punctate. Elytra not wider than the 

 prothorax and scar(;ely more tlian three-fourths longer, not quite twice as 

 long as wide; sides straight, apex broadly, obtusely rounded throughout, 

 not at all constricted ; disk coarsely, deeply subsulcate, the grooves coarsely, 

 deeply punctate ; intervals about as wide as the sulci, each with a single 

 series of fine remote punctures. Metasternura rather finely but closely punc- 

 tate, the abdomen but slightly more sparsely so. Anterior coxae large, sepa- 

 rated by scarcely one-fifth of their own width. First ventral suture broadly 

 arcuate, very fine, not impressed. Length 4.7 mm. ; width 1.3 mm.
