274 RHYNCHOPHORA. 
intermixed, the sides of the prothorax broadly, a spot on the shoulder, another on each side of the 
scutellum, and the base of the suture ochreous or whitish; the vestiture of the under surface similarly 
coloured. Head densely punctate; rostrum stout, strongly arcuate, a little longer than the head and 
prothorax, rugulosely punctate, the apical half much smoother in the 9, the antenne inserted at about 
the middle, the antennal club ovate. Prothorax transverse, feebly constricted in front, the sides arcuately 
converging from the base; densely, very finely punctate. Elytra subtriangular, finely punctate-striate, 
the interstices densely punctate. Beneath densely, finely punctate. Anterior coxe separated by about 
half their own width. Legs short. 
$. Prosternum armed with two short spines, and also excavate between them; anterior tibie feebly ungui- 
culate ; first ventral segment broadly depressed down the middle. 
Length 23-34, breadth 14-12 millim. (¢ 9.) 
Hab. Nortn America! 2, Georgia and Texas ?, New Jersey and Indiana 4.—Mexico 
(Truqui, in Mus. Brit.), Guanajuato (Sallé), Temax (Gaumer), Progreso (U.S. Nat. Mus.); 
GUATEMALA, near the city, Capetillo (Champion) ; Nicaragua, Managua (coll. Solari).— 
ANTILLES, Grenada. 
Three males and seven females. Recognizable by the dense brownish vestiture and 
the broadly ochreous or whitish margins of the prothorax. G. perscitus approaches 
G. crucifer, but it has the anterior coxee much less widely separated. 
26. Gerseus hirtipes, sp.n. (Tab. XV. figg. 9, 9a, 3.) 
Subrhomboidal, black, the prosternal spines sometimes ferruginous; somewhat thickly clothed with rather 
coarse cinereous or brownish-white scales, which are arranged in two or three lines along each elytral 
interstice, the vestiture of the under surface similar. Head closely punctate, obsoletely foveate between 
the eyes ; rostrum arcuate, stout, depressed at the base above, longer than the head and prothorax, closely 
punctate, the apical half smoother and more slender in the 9, the antenne inserted near the middle, the 
antennal club ovate. Prothorax transverse, subconical, feebly constricted in front; densely, confluently 
punctate, and with indications of a smooth median line. Elytra subtriangular, deeply punctate-striate, 
the interstices feebly convex, asperato-punctate, each elytron usually with a smoother transverse space 
on the outer part of the disc at about the middle. Beneath closely punctate. Anterior coxse narrowly 
separated. Legs more or less pilose. 
3. Prosternum armed with two long, compressed, upwardly-curved spines, and also excavate between them ; 
first ventral segment broadly depressed down the middle; all the tibiee within, and the femora beneath, 
hairy or ciliate, the anterior tibie sinuous within and strongly unguiculate at the apex. 
Length 33-43, breadth 2-24 millim. (¢ 9.) 
Hab. Mexico, Toxpam in Vera Cruz (Sallé); Guaremaua, Sinanja in Vera Paz 
(Chanipion). 
Seven specimens, all more or less worn (though the smoother bare spaces on the 
elytra are probably not abraded), one only (a rubbed ¢ ) being from Guatemala. The 
scales on the under surface are not larger than those on the upper surface. The males 
have the femora and tibie much more hairy than the females. 
27. Gerzus spiniger, sp.n. (Tab. XV. fige. 10, 10a, ¢.) 
Rhomboidal, black, the prosternal spines and antennz fusco-ferruginous; densely clothed with narrow white 
or brownish-white scales, which are arranged in three or four compact rows down each elytral interstice, 
the scales on the under surface a little larger, white, completely hiding the sculpture. Head closely pune- 
tate ; rostrum arcuate, a little longer than the head and prothorax, stout, closely punctate and squamose 
to the tip, the apical half in the 2 more slender, bare, and almost smooth, the antenne inserted at a 
little beyond (3) or slightly behind ( Q ) the middle, the antennal club ovate. Prothorax broader than
