296 RHYNCHOPHORA. 
72. Gereus ciliatipes, sp.n. (Tab. XVI. figg. 7, 7a, 3.) 
Subrhomboidal, narrow, flattened above, black, shining; thickly clothed with very small, narrow, brown and 
whitish scales, the whitish scales on the prothorax mainly condensed into three vitte and those on the 
elytra into a faint line along the first (sutural), fifth, and seventh interstices ; the vestiture of the under 
surface rather dense and white. Head finely punctate; rostrum arcuate, slightly longer than the head 
and prothorax, rather slender, finely punctate, the apical portion flattened and smoother, clothed with a 
few hairs at the tip beneath, the antenne inserted at a little beyond the middle, the autennal club ovate. 
Prothorax transverse, narrowing from the base, constricted in front; densely, finely punctate, except 
along the smooth abbreviated median line. Elytra oblong-subtriangular ; narrowly and sharply punctate- 
striate, the interstices densely punctulate. Beneath densely, finely punctate; ventral segments 1 and 2 
broadly flattened down the middle. Prosternum unimpressed behind the transverse subapical groove. 
Anterior coxee narrowly separated. Femora beneath, and the tibie within, clothed with fine hairs, those 
on the hind tibie long and conspicuous ; all the tibiee somewhat strongly unguiculate. 
Length 3-31, breadth 14-13 millim. (<.) 
Hab. Guatemaua, Calderas 7000 feet (Champion). 
Two males. The long fine hairs on the legs are doubtless peculiar to this sex: they 
are easily abraded and are almost wanting on the hind tibie in one of the two 
specimens described. Smaller, less oblong, and more shining than G. omilteme, the 
scutellum smaller and less densely squamose, the prosternum not sulcate. 
73. Gergeus dugesi, sp.n. (Tab. XVI. figg. 8, 8a, 3.) 
Oblong-rhomboidal, flattened above, nigro-piceous; thickly clothed with narrow ochraceous scales, the 
prothorax with two abbreviated vitte on the disc and a streak on the flanks, and the elytra with a vitta 
along the disc near the suture and another at the sides, blackish-brown, these markings obliterated in 
one specimen, the scales on the prothorax transversely arranged and those on the elytra clustered into 
three rows down each interstice; the vestiture of the legs and under surface dense, yellowish-white. 
Head finely punctate; rostrum a little longer than the head and prothorax, arcuate, slender, thickened at 
the base, finely punctate, except along the middle, the antenne inserted at about midway, the antennal 
club ovate. Prothorax slightly broader than long, narrowing from the base, feebly constricted in front; 
densely, finely punctate. Elytra subtriangular, rather long, narrowly punctate-striate, the interstices 
densely punctate. Beneath densely punctate. Prosternum unimpressed behind the transverse subapical 
groove. First ventral segment flattened down the middle. Anterior coxe well-separated. 
Length 4-44, breadth 1{-24 millim. (<¢.) 
Hab. Mexico, Guanajuato (Salle). 
Two males—one with the prothorax and elytra nigro-vittate (taken as the type), 
the other with the vestiture of the upper surface uniformly ochraceous. Narrower 
and more flattened above than G. ¢riviétatus, the prosternum unarmed in the male, 
the vestiture of the upper surface longer, the scutellum clothed with yellowish-white 
scales. 
74. Gereus bicruciatus, sp.n. (Tab. XVI. fige. 9, 9a, 2.) 
Elliptic, rather narrow, black ; thickly clothed with whitish scales, the prothorax with two broad vitte on the 
disc (in one specimen reduced to four spots) and a spot or elongate streak on each side, the scutellum, and 
the elytra each with a large subquadrate patch on the disc before the middle and a smaller patch towards 
the apex, these markings usually connected along the sides, fuscous or blackish. Head closely punctate ; 
rostrum strongly arcuate, about as long as the head and prothorax, moderately stout, closely punctate,
