132 RHYNCHOPHORA. 
Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith). 
Two specimens, no doubt male and female. Very like the North-American 
S. tychioides, Lec., but differing from it in the stout rostrum, the coarsely, densely 
punctate prothorax, which is also more rounded at the sides, and the sparse, piliform, 
white squamosity. ‘The eyes appear to be contiguous beneath. |

Smicronyx constrictus, Casey, Journ. New York Acad. Sci. vi. p. 396° 
Oblong-ovate, piceous, the sides of the prothorax and the elytra obscurely rufescent, the basal half of the 
antenne and the femora and tibie red; the surface thickly clothed with moderately coarse, oval, white 
scales, the elytra also with fine, inconspicuous, decumbent, white sete. Rostrum elongate, more than 
one-half longer than the prothorax, very feebly curved, finely punctured at the base and laterally, for the 
rest shining and almost smooth, the transverse basal groove deep, the antenne inserted far behind the 
middle, the latter with joint 1 of the funiculus as long as 2 and 3 united. Prothorax transverse, 
moderately rounded at the sides, constricted and narrowed in front, closely punctate, except along a not 
very narrow shining space on the middle of the disc. Elytra one-half wider than the prothorax, parallel 
towards the base, with prominent, obtuse humeri; the strie narrow, deep, and punctured, the interstices 
feebly convex and alutaceous. Tarsal claws long. 
Length 3 millim. (9.)

New Mexico *.—Muextico, Monclova in Coahuila (Dr. Palmer). 
One abraded female specimen, nearly agreeing with others from Colorado sent me 
by Mr. Wickham. The tarsal claws are longer than in the other species here 
enumerated.

OCHETINA. 
Ochetina, Pascoe, Ann. & Mag. Nat. Hist. (5) vii. p. 8302 (1881). 
A single species from the Amazons was referred to this genus by Pascoe, and a 
second from Guatemala is now added. Ochetina is very closely related to Onychylis, 
Lec., differing from it in the narrow third tarsal joint, the elongate rostrum and 
antenne, the long tarsal claws, &c. ‘The funiculus is 6-jointed, the first and second 
joints elongate. The prosternum is level. The tibie (as in Onychylis) are grooved 
along their upper and lower edges, the inner surface being densely pubescent. 
1, Ochetina induta, sp.n. (Tab. VIII. fige. 13; 13a, head and rostrum in 
profile; 136, anterior leg.) 
Obovate, robust, opaque, black, covered with smooth, uniform, greyish-brown, agglutinated scales, the antenne 
in great part and the tarsal claws ferruginous, Rostrum strongly curved, moderately stout, much longer 
than the prothorax, rugulose and squamose towards the base, smooth and shining beyond; antenne
