ORTHORIS n. g. 



This genus contains a sparsely pubescent species from California, which 

 lias a singular resemblance in form to Orchesies. It differs from the other 

 genera of this subtribe by the beak being long, slender, cylindrical and not 

 curved; it is separated from the front by a transverse impression, as usual. 

 The antennte are inserted about two-fifths from the end of the beak, the 

 scape does not quite reach the eyes; the first joint of the funicle is stouter 

 and longer than the others, which are nearly equal; the club is elongate- 

 oval, as long as the joints 2-7 of the funicle, and entirely pubescent and 

 sensitive. The front coxte are nearlj^ contiguous and the prosternum is 

 broadly, though not deeplj' sulcate in front. The legs are rather long and 

 slender, tibiis not mucronate at tip; the third joint of the tarsi broad and 

 deeply bilobed; claws simple, divergent. The prothorax is as long as wide, 

 gradually narrowed in front, Avith sides perfectly straight. Elytra wider 

 at base than the prothorax, humeri prominent, sides parallel, tips separately 

 rounded, pygidium exposed, obliquely declivous; fifth ventral longer than 

 the preceding, acutely rounded at tip. 



1. O. Orotchii, n. sp. 



Elongate, not convex above, black, moderately shining, sparsely pubes- 

 cent with rather coarse whitish hairs. Beak slender, cylindrical, nearly 

 straight, longer than the head and prothorax, sparsely punctulate towards 

 the tip, more strongly towards the base; head convex^ sparsely punctulate, 

 frontal constriction deep. Prothorax as long as wide, regularly narrowed 

 from base to tip, which is only one-half as wide as the liase; sides straight, 

 disc strongly and rather densely punctured, with a narrow smooth dorsal 

 line. Elytra one-fourth wider at base than the prothorax, humeri promi- 

 nent, rounded, sides parallel, tip rounded; striae deep, impunctured, inter- 

 spaces slightly convex, sparsely punctulate. Beneath strongly punctured, 

 punctures becoming gradually finer upon the abdomen. Length 3.5 mm.; 

 .14 inch.
