298 RHYNCHOPHOBRA. 
16. Cholus lacordairei. (Tab. XV. figg. 19,192, 2; 20, 21,6, vars.) 
Cholus lacordairei, Chevr. Bull. Soc. Ent. Fr. 1881, p. Ixxiv’. 
Hab. Mexico! (Mus. Brit.), Santecomapan in Vera Cruz (Sallé); Costa Rica, San 
Carlos (ex Mus. Dresd.). 
Var. segregatus, n. 
The elytra with a median fascia and an elongate streak near the suture before the apex white. (Fig. 20.) 
Hab. Nicaraeva, Chontales (Belt, Janson); Panama, Volcan de Chiriqui (TZrétsch, 
Champion). 
Var. schinherri, n. 
Cholus schénherri, Jekel, in litt. 
The squamosity more extended above and beneath, and partly brownish or ochreous, that on the elytra 
covering their apical two-thirds, with the exception of the rounded bare space on the subapical callosities. 
(Fig. 21.) 
Hab. British Honpuras, Rio Sarstoon (Blancaneaur); GUATEMALA (Mus. Brit.), 
Senahu, San Juan, and Panima in Vera Paz (Champion); Costa Rica, Turrialba (ex 
Mus. Dresd.). 
In the form described by Chevrolat, which occurs in Mexico and Costa Rica, the 
vestiture is entirely white, and on the elytra is reduced to a median fascia, which 
extends along the suture to the apex, so as to partly enclose a large, bare, rounded 
space. In the var. schénherri the squamosity covers more than half the surface of 
the elytra, and is brownish or ochreous in colour, becoming whitish along its ante- 
rior edge and round the subapical callosities. Twenty-one specimens are contained in 
our collection, of which three belong to the typical form, nine to the var. segregatus, 
and nine to the var. schénherri. The males have the metasternum and first ventral 
segment broadly depressed down the middle. 
17. Cholus bicinctus, sp.n. (Tab. XV. figg. 22, 22a, ¢ .) 
Subelliptic, rather convex above, black, shining; the head with a line on each side between the eyes, the 
prothorax with a large lateral patch extending from the anterior margin to near the base, the elytra 
with a basal and a median fascia, the latter extending narrowly along the suture and outer margin to the 
apex (so as to partly or entirely enclose a large, triangular, bare space), and the under surface, the ventral 
segments in part excepted, densely clothed with white or pale ochreous, oval scales, the legs with 
scattered whitish piliform scales. Head closely, finely punctate, faintly foveate between the eyes ; 
rostrum stout, curved, much longer than the prothorax, in the ¢ densely, rugulosely punctate to the tip 
and also finely carinate, in the 2 much smoother. Prothorax transverse, rounded at the sides, constricted 
and much narrowed in front; sparsely punctate, the punctures each accompanied by a small, smooth, 
crescentiform prominence, the interspaces also minutely punctate. Scutellum subcordate. Elytra elongate- 
subtriangular, at the sides forming an almost continuous outline with the prothorax, deeply, transversely 
depressed below the prominent basal margin ; seriate-punctate (except upon the space occupied by the 
fascize), the interstices flat, obsoletely granulate towards the apex. First and second ventral segments 
strongly depressed in the middle in the g. Mesosternum not raised between the coxa. Legs rather
