414 RUYNCHOPHORA. 
and tibie sometimes mottled with this colour; the elytra densely clothed with pale brown or whitish 
oval scales, intermixed with numerous short, coarse, blunt, seriately arranged sete, and with an irregular 
dark fascia beyond the middle; the rest of the vestiture, above and beneath, very sparse and setiform ; 
the legs thickly clothed with narrow brownish scales intermixed with whitish sete. Head convex, 
densely, rugosely punctate; rostrum very stout, curved, about as long as the prothorax, rugosely 
punctate, feebly carinate at the sides and base, the antenne inserted near the tip, joints 1 and 2 of the 
funiculus equal in length, 4-7 transverse. Prothorax transverse, somewhat rounded at the sides, 
constricted and narrowed in front, bisinuate at the base; very coarsely, confluently punctate, the narrow 
intervening ruge becoming longitudinal towards the apex, the dise often with a narrow flattened space 
or carina down the middle anteriorly. Elytra about one-half wider than the prothorax, parallel at the 
base, sinuate in front, the humeri rounded ; punctate-striate, the punctures oblong in shape, the inter- 
stices closely rugulose, 3, 5, 7, and 9 feebly costate throughout. Intermediate coxe rather narrowly 
separated. Mesosternum flattened, slightly hollowed in the middle in front. Ventral segments very 
sparsely, coarsely punctate, 5 feebly foveate at the apexintheg. Legs stout; femora feebly unidentate; 
. tarsal claws angularly dilated in their basal half.

Nine specimens, all from the Atlantic slope, agreeing with others from Brazil in the 
British Museum, and also with the type. Very like the North-American C. fissunguis, 
Lec., but with the tarsal claws differently formed, the alternate interstices of the elytra 
raised throughout, the sete coarse and blunt, the ventral segments sparsely punctate, 
&c, The present species is also not unlike C. setosus, Ros., but the latter has a 
peculiarly shaped mesosternum and a narrower prothorax. ‘The sculpture of the 
‘prothorax is very coarse in some examples, almost foveolate. 
_ 133. Conotrachelus semirufus, sp. n. (Tab. XX. figg. 28, 28a, ¢; 288, 
hind leg, ¢.) 
Oblong: ovate, moderately shining, ferruginous, the prothorax with a space down the middle, the elytra usually 
with the suture to about the middle, the larger prominences near it, and the apex more or less, and the 
legs often in part, black, the abdomen black or piceous ; the vestiture very sparse, whitish, somewhat 
- fasciculate on the elytra, that on the prothorax condensed into an indistinct line on each side of the disc 
and another at the sides, the inner one continued on to the base of the third elytral interstice, the femora 
more or less biannulate, the anterior pair with a faint line of fulvous scales at the base above. Head 
rugosely punctate, transversely depressed and often foveate in front; rostrum (¢) very stout, curved, 
distinctly widened towards the middle, not longer than the head and prothorax, 5-carinate, the apex 
_ Sparsely punctate, (2) a little smoother beyond the middle, the antenne inserted at about one-fourth 
from the tip, joints 1 and 2 of the funiculus equal in length. Prothorax almost as long as broad, 
constricted and abruptly narrowed in front, strongly bisinuate at the base; the surface uneven, coarsely 
rugosely punctate, and carinate down the middle anteriorly. Elytra constricted below the shoulders and 
narrowing from a little beyond this to the apex ; coarsely seriate-punctate, the interstices slightly rugulose, 
3, 5, 7, and 9 sharply costate, the ridge on 3 and 5 twice, and that on 7 once, broadly, abruptly inter- 
rupted, the median elevation on 3 very prominent. Ventral segments sparsely, finely punctate, 
1 depressed down the middle in the ¢. Intermediate coxe rather widely separated, the mesosternum 
flattened between them, vertical and shallowly emarginate in front. Legs stout; femora strongly 
clavate, each with a short triangular tooth and an indication of a very minute tooth or prominence at some
