202 RHYNCHOPHORA. 
punctate, the interstices broader than the striae, rugulose, and slightly convex. Beneath closely punctate. 
Anterior coxe narrowly separated. Legs long, rather slender ; femora acutely dentate. 
Length 2,,, breadth 1,4, millim. (9?) 
Hab. Panama, Pefia Blanca 3000 feet (Champion). 
One specimen. The ochreous sides of the prothorax and the shape and position of 
the patches of coarser whitish scales on the elytra sufficiently distinguish C. sexquttatus 
from C. apiatus and others. The elytral interstices are much wider than the strie. 
28. Cyrionyx niveipictus, sp.n. (Tab. XI. fig. 32.) 
Subovate, rather narrow, convex, ferruginous ; thickly clothed with minute, narrow scales, which are ochreous 
on the prothorax (a whitish median line, and a darker space on each side of it, excepted) and ferruginous 
on the elytra, and with various small sharply-defined patches of coarser, pure white, glistening scales— 
a spot on each side of the prothorax in front and another above each anterior coxa, a streak at the base 
of the fifth elytral interstice, an oblique streak near the middle of each elytron, and a small spot at their 
apex, an elongate patch on the metathoracic episterna, and a streak on the mesothoracic episterna ; the 
vestiture of the head, legs, and under surface sparse, whitish or ochreous, denser and wholly whitish on 
the median third of the metasternum. Rostrum stout, strongly arcuate, longer than the head and 
prothorax, striate and carinate to near the tip, the antenn inserted at about the middle. Prothorax 
transverse, rounded at the sides from near the base, strongly constricted in front; densely, finely punctate. 
Elytra subtriangular, rather long; deeply striate, the striz faintly punctate, the interstices rugulose and 
feebly convex. Beneath closely punctate. Legs long; femora acutely dentate. 
Length 2, breadth 1 millim. (2?) 
Hab. Panama, Pefia Blanca 3000 feet (Champion). 
One specimen, probably mature. A handsome little insect, with small, dense 
patches of pure white glistening scales—eight above and three on each side beneath. 
29. Cyrionyx ochreonotatus, sp. n. (Tab. XI. fig. 33.) 
Ovate, convex, black ; the prothorax with a broad vitta on each side, and the elytra with a large, rounded 
spot near the suture below the base, a smaller spot in a line with it on the outer margin, and a triangular 
patch on the oyter part of the disc near the apex, densely clothed with oval, ochreous scales: the rest 
of the vestiture of the upper surface fine and sparse, blackish above (a faint whitish median line on the 
prothorax excepted) and whitish beneath and on the legs. Rostrum strongly arcuate, not very stout, 
rugulose in its basal half and smoother thence to the tip, the antenne inserted at the middle. Prothorax 
transverse, rounded at the sides from near the base, constricted in front; densely, finely punctate. 
Elytra subtriangular, deeply striate, the strie feebly punctate, the interstices rugulose and rather convex. 
Beneath closely punctate ; ventral segments 1 and 2 broadly depressed down the middle. Legs moderately 
long; femora acutely dentate. 
Length 2, breadth 1,4; millim. (¢.) 
Hab. Panama, Bugaba (Champion). 
One specimen. The dense patches of coarse ochreous scales on the prothorax and 
elytra readily distinguish C. ochreonotatus. 
30. Cyrionyx ambatoides, sp.n. (Tab. XT. fig. 34.) 
Subovate, rather narrow, nigro-piceous, the antenne and legs obscure ferruginous; the vestiture close and 
squamiform, above and beneath: the prothorax with three sharply-defined, narrow, white vitte, the
