392 RHYNCHOPHORA. 
punctate, and sharply carinate to behind the middle. Elytra subtriangular, flattened on the disc 
anteriorly, strongly sinuate at the base, with obliquely truncated, laterally projecting humeri; seriate- 
punctate, the interstices dull, 3, 5, 7, and 9 moderately costate, the others feebly seriato-granulate, the 
ridge on 3 and 5 sinuate, that on 8 gradually rising to beyond the middle and then abruptly interrupted. 
Intermediate coxze widely separated, the mesosternum flattened between them and swollen on each side 
anteriorly. Ventral segments shining, sparsely, finely punctate. Femora strongly clavate, each with a 
proad triangular tooth and a small prominence exterior to it. Tarsal claws with a short tooth. 
Length 9, breadth 5 millim. (¢?) 
Hab. Mexico, Cordova (Hége). 
One specimen, probably a male, the long rostrum notwithstanding. A large, broad, 
robust species, with a long, convex, carinate prothorax, broadly bordered with 
yellowish-white, the elytra with a large, fulvous, apical patch and angular, laterally 
projecting humeri. C. fleruosus somewhat approaches C. levirostris. An unnamed 
form from Cayenne in the British Museum is still more like it. 
18. Conotrachelus fulvomaculatus, sp.n. (Tab. XVIII. figg. 16, 16a, .) 
Oblong-ovate, shining, piceous or rufo-piceous, the legs, rostrum, and antenne obscure ferruginous; the 
prothorax and elytra with numerous irregular patches of small, oval or oblong, fulvous scales, the elytra 
also with a few small patches of white scales intermixed, the vestiture of the head close and fulvous, that 
of the under surface very sparse and whitish, and that of the legs fulvous and whitish intermixed, the 
femora faintly annulate towards the tip, the anterior pair with a line of piliform fulvous scales along 
their basal half above. Head closely punctate, deeply foveate between the eyes; rostrum moderately 
stout, feebly curved, laterally sulcate, almost smooth, in the ¢ shorter, and in the 2 as long as or longer 
than the elytra, the antenna in the ¢ inserted at one-third from the apex and in the Q at or behind the 
middle, joints 1 and 2 of the funiculus very elongate, subequal in length. Prothorax transverse, abruptly 
narrowed in front, strongly bisinuate at the base; coarsely, rugosely punctate, with a raised smooth space 
down the middle and various other smooth, irregular, raised spaces scattered over the rest of the disc. 
Klytra elongato-cordate, deeply sinuate at the base; coarsely seriate-punctate, the interstices uneven, 
3, 5, 7, and 9 costate throughout. Mesosternum flattened between the coxe, somewhat protuberant in 
front. Ventral segments very sparsely, finely punctate. Legs elongate; femora clavate, sparsely 
punctate, unidentate ; tarsal claws with a short tooth. 
Length 93-104, breadth 43-5 millim. (¢ @.) 
Lab. Nicaracua, Chontales (Belt). 
Four specimens. The almost smooth, bare rostrum in both sexes, the uninterrupted 
elytral coste, the uneven disc of the prothorax, and the large patches of oval fulvous 
scales (which are intermixed with white on the elytra) scattered over the upper 
surface, &c., separate C. fulvomaculatus at a glance from C. rectirostris and its allies. 
19. Conotrachelus robustus, sp. n. 
Oblong-ovate, broad, robust, dull, piceous or rufo-piceous; the vestiture sparse, fulvous or ochreous, sub- 
fasciculate on the elytra, condensed into a small, narrow patch on the humeri in front, a minute spot at 
each hind angle of the prothorax, and a faint sinuous line or streak on each side of the disc of the latter, 
the femora each with an ochreous or whitish ring, the anterior pair with a rather broad line of fulvous 
scales along their basal half above. Head closely punctate, depressed and feebly foveate between the 
eyes ; rostrum (¢) very stout, curved, much longer than the head and prothorax, 5-carinate, thickly 
punctate at the apex, (2) more slender, the antenne in the ¢ inserted at about one-third from the 
apex and in the 2 a little before the middle, joints 1 and 2 of the funiculus subequal in length.
