KEY TO EASTERN SUETRIBES OF ERIRHIXIXI. 



a. Body normally scaly or pubescent, not covered with a waterproof 



crust. 



&. Eyes distant from front margin of thorax, separated from the 

 latter by a space equal to or greater than their own diameters. 



I. DERELOMI, p. 190. 

 bb. Eyes contiguous to front margin of thorax, often partly covered by 



the latter in repose. 



c. Beak not constricted at base; claws divergent. II. ERIRHIXI, p. 193. 

 cc. Beak constricted at base (i. e. sharply separated from head by a 

 transverse line) (Fig. 65, m., n.. o.) ; claws connate or approxi- 

 mate. III. SMICROXYCHI, p. 201. 

 aa. Body covered with a dense, varnish-like, waterproof coating of scales.

Snbtribe I. DERELOMI. 



This subtribe, as here included, is equivalent to the tribe Dere- 

 lomini of LeConte, and his group Eugnomi of the Erirhinini. 

 It comprises small oblong, almost or wholly glabrous species hav- 

 ing the beak long, slender, cylindrical ; head more or less pro- 

 longed behind the eyes, the latter small, coarsely granulated; an- 

 tenna 1 inserted about one-fourth from tip of beak, scape slender, 

 reaching the eyes; funicle 7- join ted ; first, second and fifth ven- 

 tral segments long, third and fourth united not equal to second
