280 RHYNCHOPHORA. 
Hab. Mexico, Jalapa (Hége), Toxpam (Sallé), Teapa (Sallé, H. H. Smith); GuateE- 
MALA, Trece Aguas (U.S. Nat. Mus.). ; 
Found in numbers at Teapa. Smaller, narrower, and more sparsely squamose than 
G. lentiginosus ; the rostrum stouter, especially in the male; the elytra with numerous 
intermixed fuscous scales, which are usually condensed into a common transverse spot 
at (instead of beyond) the middle of the suture, the vestiture arranged in from one to 
three lines on the alternate interstices and in single lines on the others; the prosternal 
spines stouter in well-developed males. Narrower and more sparsely squamose than 
G. metecus, the anterior tibie sharply unguiculate in the male. Three specimens from 
Chiacam with darker legs and closer vestiture may also belong here. ‘The mandibles 
are slightly decussate at the tip. 
39. Gerzeus meteecus, sp. n. 
_ Elliptic, nigro-piceous or piceous, the antenna, tibie, tarsi, and tip of the rostrum more or less ferruginous ; 
thickly clothed with rather coarse, narrow, intermixed ochreous (or cinereous) and fuscous scales, the 
light-coloured scales condensed into three broad faint vitte on the prothorax and various short streaks on 
the elytra (especially at the base of the first and second interstices) ; the vestiture of the under surface 
closer and whitish. Rostrum stout, half the length of the body, abruptly bowed from near the base, 
thickly punctate and subcarinate in its basal half and more sparsely punctured thence to the tip. Pro- 
thorax and elytra sculptured as in G. lentiginosus. Prosternum deeply sulcate in the ¢, shallowly so in 
the 2, armed in the ¢ with two moderately long spines, which in one specimen are reduced to two 
small conical tubercles. Anterior tibie obsoletely unguiculate in both sexes, not hollowed within 
in the ¢. 
Length 23-8, breadth 14-14 millim. (¢ 9.) 
Hab. Mexico, Teapa (H. H. Smith) ; Guatemata, Cahabon (Champion), Trece Aguas 
(U.S. Nat. Mus.); Nicaragua, Chontales (Janson). 
Four males and five females. Very like @. lentiginosus, and likely to be confounded 
with it, but separable by the very feebly unguiculate, non-emarginate anterior tibie of 
the male, and the mottled elytral vestiture. The obsoletely unguiculate anterior tibie 
also distinguishes G. metecus from other nearly allied forms. There is sometimes a 
transverse dark mark at the middle of the suture, as in G. s¢mulator. 
40. Gerzeus amplicollis, sp.n. (Tab. XV. figg. 13, 13.4, ¢.) 
Subovate, rather convex, nigro-piceous, the elytra, rostrum, antenne, and legs fusco-castaneous ; above sparsely 
clothed with minute, pallid, hair-like scales, the elytra with an oblong patch of coarser whitish scales at 
the base of the third interstice, the under surface also sparsely albo-squamose. Head closely punctate ; 
rostrum strongly arcuate, about as long as the head and prothorax, rather stout, thickened towards the 
base, closely, coarsely punctate, the apical half almost smooth in the 9, the antenne inserted at about the 
middle, the antennal club short-ovate, stout. Prothorax somewhat convex, strongly transverse, rounded 
at the sides, narrow and tubulate in front; rather coarsely, densely punctate (the punctures not coarser 
on the anterior lobe), and with indications of a raised median line. Scutellum transverse. Elytra sub- 
triangular, transversely depressed on the disc beyond the middle, sharply striate, the interstices broad and 
closely, coarsely punctate. Beneath closely punctate. Anterior tibie almost straight on their inner 
edge.
