296. RHYNCHOPHORA. 
prothorax (as seen with the vestiture intact); the non-prominent humeri; the broad, 
semi-erect, intermixed setiform scales on the elytra; and the rudimentary condition 
of the wings. 
10. Eustylus cinericius, sp. n. 
Elongate, rather convex, narrow (¢), broader (Q), piceous or ferruginous ; densely clothed with whitish, 
cinereous, or greyish-brown scales (which often have a cupreous or greenish tinge in certain lights), the 
elytra sometimes with a faint oblique darker fascia crossing the disc at about the middle (perhaps due 
to discoloration), the surface also set with scattered, curled, short, decumbent sete. Head and rostrum 
sulcate, the rostrum subquadrate, the scrobes subparallel, the head flattened between the eyes and 
convex behind them, the latter rounded and very prominent ; antennal scape stout, reaching beyond the 
front of the prothorax. Prothorax longer than broad, slightly rounded at the sides, subtruncate at the 
base, and often feebly grooved down the middle; impressed with coarse scattered punctures, intermixed 
with a fine close interstitial punctuation. Scutellum depressed or very small. Elytra moderately 
long, slightly narrowed anteriorly in both sexes, broader and widened to near the middle in Q, the 
sutural region broadly flattened to near the apical declivity, the humeri oblique and not prominent ; 
coarsely punctate-striate, the alternate dorsal interstices raised. Legs stout; anterior femora unarmed. 
Wings rudimentary. 
Length 43-82, breadth 13-31 millim. (¢ @.) 
Hab. GuateMaa, San Gerdnimo, Cerro Zunil (Champion). 
Twenty-four specimens, those from San Gerdnimo with the vestiture more or less 
discoloured by a brownish exudation. From ZH. subapterus the present species may be 
known by the more convex basal portion of the head, the coarsely punctured prothorax, 
the small curled elytral setee (which replace the intermixed broad, suberect scales), and 
the almost uniform cinereous or greyish vestiture. The head and rostrum are found 
to be deeply sulcate when the scales are removed. The metathoracic episterna are 
dilated anteriorly, as in the fully-winged forms. 
PSEUDEUSTYLUS, gen. nov. 
Mentum large, almost filling the buccal cavity ; scrobes superior, broad, deep, extending backwards to the 
eyes, becoming broader, shallower, and squamose behind the points of insertion of the antenne; nasal 
plate triangular, on the same plane as the anterior part of the rostrum and not limited behind by a 
conspicuous ridge; eyes very large; antenne with a long, feebly clavate, rather slender scape, an 
elongated second joint to the funiculus, and an elongate club; scutellum large; elytra elongate, 
10-striate, the outer striae free, the humeri prominent; anterior femora toothed ; anterior and inter- 
mediate tibie unguiculate ; posterior tibiz narrowly lamellate at the apex, the glabrous articular surface 
large and cavernous ; tarsal claws free; body winged, elongate, squamose; the other characters as in 
Eustylus. 
Type, P. cupreoviridis. 
The two species from which the above characters are taken agree with Hustylus 
puber and EL. sexguttatus in having toothed anterior femora, but the posteriorly 
widened and produced scrobes and the flattened nasal plate readily distinguish them 
from all the members of that genus.
