312 RHYNCHOPHORA. 
8 Erethistes lineatocollis, sp.n. (Tab. XVI. figg. 23, 23a, ¢.) 
Elliptic, black, shining, the antenne ferruginous at the base ; clothed above with scattered, coarse, oval, whitish 
scales, which are condensed into a line along the inner margin of each of the eyes, three narrow vitts on 
the prothorax, and numerous irregular patches on the elytra, the larger markings on the latter arranged 
in an interrupted longitudinal series near the suture and a broader one on the outer part of the disc; the 
under surface densely clothed with similar, yellowish-white scales, the vestiture of the legs sparser and 
piliform. Head sparsely punctate, narrowly sulcate between the eyes, which are large and rather 
prominent; rostrum moderately stout, about as long as the prothorax, curved, depressed at the base 
above, and somewhat abruptly declivous towards the apex, almost smooth, the antennz inserted a little 
before the middle, joint 2 of the funiculus nearly twice as long as 3. Prothorax broader than long, 
subconical, feebly rounded at the sides, slightly constricted in front, the spaces between the vittz almost 
smooth. Scutellum scutiform. Elytra considerably wider than the prothorax, elongato-cordate, trans- 
versely depressed at the base; shallowly seriate-punctate and obsoletely foveolate, the interspaces 
between the scattered patches of scales smooth. Anterior cox narrowly separated; mesosternum 
flattened and rather narrow between the cox. Ventral segments 1 and 2 broadly flattened down the 
middle. Legs moderately elongate; femora each with an acute tooth, the posterior pair extending a 
little beyond the apex of the abdomen; tibiz nnarmed at the outer apical angle. 
Length 114, breadth 43 millim. (d¢.) 
Hab. Nicaracua, Chontales (Janson). 
One specimen. The comparatively short, almost smooth, basally depressed rostrum, 
the trivittate prothorax, the mottled, elongato-cordate elytra, the shining, almost smooth, 
bare interspaces of the upper surface, and the coarse, whitish squamosity, render this 
species easily recognizable. The rostrum is shaped very much as in Cholus fusiformis. 
4. Erethistes zygopoides, sp. n. (Tab. XVI. figg. 24, 24 a, b.) 
Elongate, narrow, widened anteriorly, flattened above and convex beneath, piceous, the rostrum, antenne, and 
legs reddish; the upper surface, except upon the small, smooth, shining granules, somewhat thickly 
clothed with minute, narrow, ochreous scales ; the under surface sparsely clothed with similarly coloured, 
coarser scales, which are condensed into patches on the side-pieces of the meso- and metasternum ; the 
legs sparsely clothed with short, whitish hairs, Head convex, granulate and closely punctate, the eyes 
comparatively small and very widely separated; rostrum moderately stout, long, curved, bare and very 
sparsely punctate throughout, the antenne inserted at the middle. Prothorax nearly as long as broad, 
emarginate in front, rapidly narrowing from the middle forwards, and also slightly narrowed behind, 
closely granulate, with distinct ocular lobes, the hind angles rather sharp. Scutellum small, flattened, 
subcordate. Elytra twice the length of the prothorax, and slightly wider than it at the base, obconic, 
subtruncate in front, conjointly rounded at the apex; the disc seriato-granulate and indistinctly seriate- 
punctate, the granulation becoming obsolete at the sides, where the punctures are large and foveiform. 
Ventral segments ascending, 1 granulate in the middle. Anterior cox moderately distant. Mesosternum 
not raised between the coxe. Legs elongate; femora almost linear, each armed with a narrow, acute 
tooth, the hind pair reaching a little beyond the apex of the abdomen; tibie unarmed at the outer 
. apical angle. 
Length 124, breadth 43 millim. (? 9.) 
Hab, Guatemata, Purula in Vera Paz (Champion). 
One specimen. This curious species approaches the Brazilian EF. tetricus (Fahr.) ; 
but it is larger and much more elongate, and more convex beneath; the prothorax is 
longer, widest at the middle, with distinct ocular lobes; the elytra are subtruncate at 
the base, &c.
