500 RHYNCHOPHORA. 
Hab. Mexico, Guanajuato (Sallé: 3), Omilteme, Chilpancingo (7. H. Smith: -? ). 
One male and two females, the latter in very fresh condition. Larger and more 
densely squamose than G. hospes, the rostrum less abruptly narrowed (especially in 
the 2), the scutellum almost bare, the anterior tibiz of the male not excised near the 
tip beneath, the antennal club stouter. The much denser vestiture, the hollowed and 
distinctly unguiculate anterior tibie of the male, &c., separate G. candidus from 
G. tonsilis. 
81. Gerzeus hospes. (Tab. XVI. figg. 15, 15a, b, ¢; 16, 2.) 
9. Centrinus hospes, Casey, Ann. N. York Acad. Sci. vi. pp. 575, 585°. 
Oblong-rhomboidal, black, the antenne and tarsal claws usually more or less ferruginous; above thickly and 
uniformly clothed with narrow whitish or brownish-white scales, the under surface with larger and 
broader white scales. Head finely punctate ; rostrum arcuate, longer than the head and prothorax, much 
thickened in ifs basal half, squamose and closely punctate,—the apical portion in the 2 longer, abruptly 
flattened, almost smooth, and slender,—the antenne inserted at a little behind the middle in the ¢, 
and at about the basal third in the 9, the antennal club ovate.. Prothorax transverse, narrowing 
from the base, feebly constricted in front; densely, finely punctate. Scutellum squamose. Elytra 
subtriangular, shallowly punctate-striate, the interstices densely, rugulosely punctate, each with two or 
three rows of scales. Beneath densely punctate ; first ventral segment fiattened in the middle in the ¢. 
Prosternum almost unimpressed. Anterior cox separated by a little less than half their own width. 
Legs moderately long. 
dg. Anterior and intermediate tibie strongly unguiculate, the anterior pair widened from near the base and 
abruptly notched beneath just before the tip, the intermediate pair also sinuous ; posterior tibie hairy 
on the inner side at the apex. 
Length 3-4, breadth 14-2 millim. (¢ 9.) 
Hab. NortH America, Tucson in Arizona!.—Mexico (Dupont and Truqui, in Mus. 
Brit.), Chilpancingo (H. H. Smith), Yautepec, Irapuato, Iguaia, Cordova, Oaxaca 
(Hoge), Guanajuato, Toxpam (Sallé), San Rafael Jicaltepec (U.S. Nat. Mus.); 
GuaTeMaLA, San Gerdnimo (Champion); Costa Rica, Escazu 1200 metres (Biolley), 
Atenas (U.S. Nat. Mus.); Panama, Volcan de Chiriqui (Champion). 
Sent in numbers from Chilpancingo and Escazu; the Costa Rican specimens are 
labelled as having been found on a species of Croton. Smaller and duller than 
G. tonsilis; the rostrum of the female (fig. 16) abruptly narrowed at about the basal 
third. and quite slender and almost smooth thence to the apex, the antenne inserted 
far behind the middle in this sex; the prothorax more transverse; the anterior tibive 
of the male abruptly notched beneath near the apex and strongly unguiculate (fig. 155). 
The vestiture is denser in some examples than in others. A male and female from 
Chilpancingo are figured. G. hospes was described from a single female specimen 
and the identification is perhaps doubtful. 
82. Gereeus incolatus, sp. n. 
Rhomboidal, rather narrow, black, shining, the antenne and tarsi more or less ferruginous; above rather 
sparsely clothed with narrow yellowish-white scales, which are arranged in two or three rows down each 
elytral interstice, the vestiture of the under surface coarser, closer, and wholly whitish. Head finely 
punctate; rostrum strongly arcuate, a little longer than the head and prothorax, stout, tapering towards
