644 RHYNCHOPHORA. 
a shallowly emarginate mesosternum, differently marked elytra, &. The prothorax 
is less sinuate at the base, and the tarsal claws are longer, than in Trachalus 
micronychus. ‘The anterior tarsi of the male appear to have a few projecting, longer 
hairs. 
Species moderately large, robust, oblong or elongate, squamose, with the eyes large and covered 
in repose, the rostrum short (except in C. octomaculatus, ?), the antennal club ovate, the 
prothorax rounded at the sides and coarsely punctate, the scutellum small, the elytra 
oblong, maculate, the interstices flat or convex, the mesosternum arcuate-emarginate 
(horseshoe-shaped in C. octomaculatus, 2), the ventral segment 2 longer than 3, the legs 
stout, the femora unidentate. (Nos. 19-22.) 
These forms approach Metriophilus. 
19. Cryptorrhynchus foveifrons, sp.n. (Tab. XXXI. figg. 24, 24a.) 
Elongate-ovate, robust, shining, black, the antenne ferruginous; the head, prothorax, and underside very 
sparsely, and the rest of the surface densely, clothed with reddish-brown and pale ochreous scales, the 
latter mainly concentrated on the elytra between and around the black dorsal patches and along the outer 
margin, the dark markings consisting of a common, transverse, quadrate patch at the base, a common 
pyriform patch beyond the middle, a short sinuous line on the suture at the apex, and a small spot on 
each side of this on the apical margin, the elytra also set with short, coarse, decumbent sete. Head very 
coarsely punctate, carinate on each side around the widely separated eyes, and sulcate and deeply foveate 
between them, the fovea limited anteriorly by a short, stout, longitudinal ridge; rostrum cylindrical, 
short, stout, curved, slightly narrowed towards the base, sparsely, rather coarsely punctate, except along 
the centre, sulcate at the sides, the antenne inserted towards the apex, stout, joints 3-7 of the funiculus 
equal in length, 2 shorter than 1, the club short, ovate. Prothorax transverse, strongly rounded at the 
sides, narrowed and feebly constricted in front; coarsely, densely punctate. Scutellum rounded. Elytra 
much wider than the prothorax, parallel in their basal half; coarsely seriate-punctate, the interstices 
almost flat, closely punctulate and obsoletely granulate. Beneath coarsely, closely punctate. Mesosternum 
arcuate-emarginate. Legs very stout, short, the femora feebly clavate, unidentate, the tibie sinuate 
within. 
Length 74, breadth 34 millim. (¢.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. Near C. v-nigrum, but with the elytral markings different (the 
v-shaped dorsal patch being replaced by one of pyriform shape, the triangular lateral 
spot wanting, &c.), the vestiture not so coarse, the frontal fovea larger and sulciform, 
the prothorax less coarsely punctate, the scutellum larger. 
20. Cryptorrhynchus V-nigrum, sp. n. (Tab. XXXI. figg. 25, 25 a.) 
Oblong-ovate, robust, shining, black, the antenne ferruginous ; the head, prothorax, and underside sparsely, and 
the rest of the surface thickly, clothed with coarse, intermixed pale ochreous and fulvous scales, the elytra 
with a common, interrupted, transverse, subquadrate patch at the base, a common V-shaped mark on the 
disc beyond the middle, a triangular patch at the sides exterior to this, and a small transversely cordate spot 
on the suture at the apex, black or blackish-brown, the fulvous scales condensed on each elytron into a 
broad elongate streak on the outer part of the disc and a patch towards the apex, the tibie with a black 
spot on the outer edge near the base; the elytra also set with short, coarse, decumbent sete. Head very 
coarsely punctate, feebly carinate on each side around the widely separated eyes and deeply foveate 
between them; rostrum curved, short, very stout, cylindrical, sulcate laterally, seriate-punctate, except
