624 RHYNCHOPHORA. 
Species small, oblong-ovate or subovate, squamose and setose or setulose, with the rostrum 
arcuate, slightly widened towards the base (except in C. uncipes and C. collabismoides), the 
eyes large and not very widely separated (except in C. flohri), the antennal club ovate 
or oblong-ovate, the prothorax bisinuate at the base, with feebly developed ocular lobes, the 
scutellum filling the cavity, the elytra much wider than the prothorax, with the alternate 
interstices not or feebly raised, the mesosternum prominent, arcuately or subangularly 
emarginate, the metathoracic episterna moderately broad, the ventral segment 2 longer 
than 8, the legs rather slender, the femora unidentate. (Nos. 96-121.) 
Antennal club ovate. (Nos. 96-117.) 
Antennal club oblong-ovate. (Nos. 118-121.) 
96. Cryptorrhynchus uncipes, sp. n. (Tab. XXXIII. figg. 27, ¢ ; 28, hind 
leg, 3.) 
Oblong-ovate, shining, black or piceous, the antenne ferruginous; thickly clothed with fulvous scales, the 
prothorax with two darker sinuous vitte on the disc, the elytra slightly mottled with cinereous and 
blackish-brown, the upper surface also set with rather long, coarse, semierect sete, the vestiture of the 
abdomen sparse, the legs setulose. Head rugulosely punctate, flattened between the somewhat widely 
separated eyes; rostrum cylindrical, about as long as the prothorax, feebly curved, rugulosely punctate 
and squamose to near the middle and minutely punctate thence to the tip, smoother in the 9, the antennz 
inserted at about midway, joint 2 of the funiculus a little shorter than 1, the club ovate. Prothorax 
broader than long, constricted and much narrowed in front; densely, finely punctate. Scutellum 
rounded. LElytra considerably wider than the prothorax, subparallel in their basal half; with rows of 
rather coarse, subquadrate punctures placed in narrow striae, the interstices somewhat convex. Beneath 
shining, coarsely, closely punctate. Mesosternum prominent, arcuate-emarginate. Legs moderately 
long, rather slender; femora feebly clavate, sharply unidentate ; tibie almost straight on their outer 
edge, sinuous i the posterior pair of the ¢ excavate on the inner edge at the apex and with the 
apex itself strongly unguiculate. 
Var.? Narrower and a little more elongate, the vestiture much darker, that on the elytra fulvous and black 
intermixed. 
Length 33-5, breadth 13-2} millim. (¢ 9.) 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
_ Found in abundance in Chiriqui. The form of the posterior tibie of the male, 
similar to that of various Conotracheli, will help to distinguish C. wncipes *. The variety 
is represented by a single rather worn male ; it may belong to a different species. 
97. Cryptorrhynchus simplex, sp. n. 
Very similar to C. wncipes, but with the vestiture brown, slightly intermixed with cinereous, the sete rather 
longer ; the eyes larger and more approximate; the rostrum a little shorter, thickly squamose to near 
the middle in the 3; joints 1 and 2 of the funiculus equal in length; the ventral segments more finely 
punctate ; the tibie less sinuate within, the posterior pair neither excavate nor strongly unguiculate at 
the apex in the ¢. 
Length 33-43, breadth 14-2 millim. (¢ 2.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Ten specimens, mostly in dirty condition, which were at first confused by me with 
C. uncipes, but they have the posterior tibie similarly formed in the two sexes, &c. 
The ventral surface is shining in both species. 
* The insect is narrower than represented on the Plate.
