160 RHYNCHOPHORA. 
subapical callosities, extending inward to near the suture, and deeply triangularly excised at the middle, 
—an oblong spot near the outer margin of each elytron at the apex, and the lower part of the propleura, 
densely clothed with narrow ochreous scales, the rest of the vestiture sparse and fine, fuscous above and 
cinereous beneath. Rostrum strongly arcuate, stout, thickly punctate, rugose and carinate at the base. 
Joint 2 of the funiculus a little longer than 1. Prothorax slightly broader than long, densely, finely, 
rugulosely punctate. Elytra long, finely punctate-striate, the interstices flat, closely, minutely punctate. 
Ventral segments 1 and 2 broadly excavate down the middle in the d. 
Length 52-61, breadth 2-2-1, millim. (¢ 2.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Three specimens. Less opaque than A. sinwatus, the elytral vitte still broader, not 
reaching the apex, and separated by a narrow dark sutural stripe, which 1s widened 
out at the middle into a large rhomboidal patch, the vittee themselves clothed with 
narrower scales, the vestiture of the under surface much sparser. 
9. Ambates belti, sp.n. (Tab. IX. figg. 21, 21a, 2.) 
Moderately elongate, opaque, piceous, the rostrum, antenne, and legs more or less ferruginous ; the prothorax 
with a vitta on each side, extending on to the head and rostrum, and a faint median line, and the elytra 
with a sinuous posteriorly abbreviated stripe on the outer part of the disc, the sides, a line along the 
suture, and various others exterior to it at the base, and an oblong spot at the apex, densely clothed with 
pale ochreous scales, the elytral vittee bordered within by a broad, sinuous, blackish or brown stripe and 
towards the apex externally by an oblong dark patch; the rest of the vestiture of the upper surface 
brownish, that of the under surface dense and whitish. Rostrum longer than the head and prothorax, 
strongly arcuate, moderately stout, carinate and rugulosely punctate, the apical half sparsely and very 
finely punctate. Joints 1 and 2 of the funiculus equal in length. Prothorax broader than long, rounded 
at the sides anteriorly; densely, finely, rugulosely punctate. Elytra finely punctate-striate, the 
interstices flat and densely punctate. 
Length 44-5, breadth 17-2 millim. (@.) 
Hab. Nicaragua, Chontales (Belt). 
Two females. Near A. triangularis, but with the sinuous elytral vitte much 
narrower, abruptly interrupted towards the apex (not below the base), and bordered 
within by a dark stripe, the rostrum (2 ) smoother beyond the middle. The antenne 
are inserted at about the middle of the rostrum. 
10. Ambates fasciolatus, sp.n. (Tab. IX. fig. 22, 2.) 
Ambates fasciolatus, Chevr. Ann. Soc. Ent. Fr. 1877, p. 341°. 
Hab. Mexico !, Santacomapan in Vera Cruz (Sai/é). 
Of this species we have received a single female specimen. It may be identified by 
the common, narrow, curved, ochreous, impressed fascia at about the middle of the 
elytra, and the irregular patches of rust-red scales along the sides of the body beneath, 
the one on the second ventral segment being the most conspicuous. The second joint 
of the funiculus is longer than the first and the head is distinctly foveate between 
the eyes.
