220 RHYNCHOPHORA. 
the Chiriqui and Mexican examples, and obtuse or subrectangular in those from San 
Gerénimo and Panajachel respectively. This species differs from C. explanatus in its 
narrower shape, the less nodose prothorax, the more coarsely punctured elytral strie, the 
convex, shining interstices, the more obtuse humeri, and the unarmed posterior femora ; 
and from C. chiragra (Fabr.) in its more elongate shape, the less rounded sides of the 
prothorax, and the angular lateral dilatation of the elytra. The varietal form may 
prove to be distinct. 
4, Camptochirus deplanatus, sp. n. (Tab. XII. fig. 18.) 
Elongate, narrow, slightly shining, black, the tip of the rostrum, the front of the prothorax, the shoulders 
and the apical margin of the elytra, the antennz (the basal half of the club excepted), the intermediate 
and hind legs (the middle of the femora excepted), the anterior tarsi and knees, and the apex of the 
anterior tibie, ferruginous or rufo-testaceous ; the surface mottled with grey and brownish pubescence, 
the suture of the elytra with an elongate streak of velvety-black hairs at the middle, the vestiture of the 
scutellum white. Head, rostrum, and antenne as in C. angulatus. Prothorax broader than long, 
narrowed and constricted in front and narrowed behind, closely punctate, the dis¢ feebly quadrinodose. 
Elytra wider than the prothorax, elongato-quadrate, flat on the disc, the humeri swollen and subangular, 
the apices separately rounded; deeply punctate-striate, the punctures oblong in shape, the interstices 
convex, densely rugulose, 4-6 conjointly, subrectangularly lamellato-explanate at their point of termi- 
nation. Intermediate femora toothed, the posterior pair unarmed. 
Length 3-34, breadth 17-13 millim. (¢ Q.) 
Hab. Muxico, Toxpam (Sallé), Jalapa (Hége),. 
Two specimens. This is perhaps a feebly developed form of C. angulatus, from 
which it differs in its smaller size, the less nodose prothorax, and the more flattened 
disc of the elytra. It is very like C. angustus, Pasc., from Colombia, but has the 
subapical plate of the elytra rather large and angular (instead of rounded and incon- 
spicuous), and the anterior tibie less acutely produced at the inner apical angle. 
THEMEROPIS. 
Themeropis, Pascoe, Journ. Linn. Soc., Zool. xii. pp. 30, 33 (1874). 
The two described species of this genus are from the Amazons and Parana 
respectively ; a third is added from Central America. 
1. Themeropis binodosa, sp. n. (Tab. XII. figg. 19, 19 a.) 
Subconical, robust, dull, piceous, the antenne (the two basal joints of the club excepted), the anterior femora 
at the tip, the intermediate and posterior femora at the base and apex, the anterior tarsi in part, the 
anterior tibie at the base and apex, and the intermediate and posterior tibiz and tarsi entirely, ferruginous 
or testaceous; clothed with fine pubescence, which is of a fulvous colour on the dorsal surface of the 
elytra and greyish elsewhere. Head closely punctate, the eyes very large and coarsely facetted ; rostrum 
stout, curved, about as long as the prothorax, shining, faintly carinate and rugulosely punctate at the base, 
for the rest very sparsely punctured, the antennw inserted at the middle, the club of the latter loosely 
articulate and slightly longer than the funiculus, joints 3-7 of which are small and closely articulate. 
Prothorax subconical, a little broader than long, feebly constricted in front, closely, rugulosely punctate. 
Elytra much wider than the prothorax, widening to near the apex, and separately rounded at the tip, 
transversely gibbous at the middle and rapidly sloping thence to the apex, the humeri swollen, sub-
