GEREUS.,. 307 
are condensed into a marginal stripe on each side of the prothorax and various short 
streaks at the base of the elytra and a patch on their disc beyond the middle. The 
apical portion of the rostrum of the female becomes abruptly slender and almost 
smooth, much as in G. hospes. 
96. Gerus farinosus, sp. a. (Tab. XVI. figg. 20, 204, o.) 
Elliptic, piceous, the antenne, tip of the rostrum, and legs rufescent; densely clothed with rather broad, 
' imbricate, yellowish-white scales, which are arranged in three or four rows down each elytral interstice 
(the first with two rows only), the vestiture of the under surface whiter. Head closely punctate ; 
rostrum arcuate, stout, about as long as the head and prothorax, closely punctate and finely carinate, 
the apical half shining and a little smoother in the 9, the antenne inserted at the middle, joints 2-7 
of the funiculus short, widening outwards, 2 a little longer than 3, the club ovate. Prothorax 
transverse, rapidly and arcuately narrowing from near the base, feebly constricted in front, the median 
lobe impinging on the scutellar cavity; densely, finely punctate. Scutellum small, squamose. LElytra 
subtriangular, finely striate, the interstices rugulosely punctulate. Beneath densely punctate. Prosternum 
unarmed, hollowed in the middle anteriorly and also on the flanks behind the eyes. Legs short; anterior 
tibiee feebly unguiculate. 
Length 2-23, breadth 1-1} millim. (¢ @.) 
Hab. Muxico, Teapa (H. H. Smith); Nicaragua, Managua (Solari). 
Seven specimens, all but one from Managua, those obtained by Signor Solari being 
in very fresh condition. This species resembles G. picumnus (Herbst) and G. albotectus 
(Casey) (for examples of which we are indebted to Capt. Casey); but it has the coarse 
vestiture longer and denser (hiding the sculpture), the prosternum unarmed in the 
male, and the rostrum stouter, shorter, and closely punctate. The basal median lobe 
of the prothorax is considerably produced, reducing the size of the scutellum. 
97. Gereus duponti, sp. n. 
Subrhomboidal, narrow, piceous, the antenne in part, the tip of the rostrum, tibia, and tarsi ferruginous ; 
somewhat thickly clothed with small, narrow, intermixed brown and ochreous scales, the ochreous scales 
on the prothorax condensed into three faint vittee and those on the elytra into various long and short 
streaks at the base and a faint streak on the fifth interstice beyond the middle; the vestiture of the 
under surface close and whitish. Head closely punctate; rostrum arcuate, moderately stout, as long as or 
a little longer than the head and prothorax, striate and closely punctate, smoother at the tip, the antenne 
inserted slightly beyond the middle, the antennal club ovate. Prothorax transverse, subconical, feebly 
constricted in front ; densely, finely punctate. Scutellum small, almost bare. Elytra triangular, the 
humeri somewhat prominent; sharply striate, the interstices rugulosely punctate. Beneath densely 
punctate ; first ventral segment hollowed down the middle. Prosternum unimpressed behind the shallow 
transverse subapical groove. Anterior and intermediate tibie strongly unguiculate. 
Length 23-23, breadth 14 millim. (¢.) 
Hab. Mexico (Dupont, in Mus. Brit.) ; Guatemata, near the city (Champion). 
Two males, varying only in the length of the rostrum. Very similar to G. mendax, 
but rhomboidal in form (the prothorax and elytra each rapidly narrowing from the 
base), the vestiture of the upper surface finer, that of the elytra in great part brown, 
the ochreous scales condensed into several streaks at the base and on the disc. The 
specimen in the British Museum is labelled G. lentiginosus ?
