636 RHYNCHOPHORA. 
reddish-brown scales and scattered, coarse, decumbent, squamiform sete, the apical declivity with a very 
large, subcordate, brownish-white patch, which is mottled with ochreous towards the tip, the vestiture of 
the rest of the surface ochreous and whitish, the legs setulose, the femora subannulate. Head densely 
punctate, slightly depressed between the eyes, which are rather widely separated ; rostrum very stout, 
about as long as the prothorax, feebly curved, rugose and carinate in its basal half, sparsely punctate at 
the tip, the antenne inserted a little beyond the middle, joints 1 and 2 of the funiculus equal in length, 
the club ovate, with very distinct sutures. Prothorax broader than long, constricted and much narrowed 
in front, the sides gradually converging from the base and slightly rounded anteriorly, the base itself 
subtruncate ; densely punctate. Scutellum rounded. Elytra a little wider than the prothorax, subconical, 
somewhat gibbous, compressed at the sides, the humeri rounded; with rows of subquadrate, oblong 
punctures, the interstices flat, rugulose towards the suture and on the apical declivity, 1 (sutural) and 5 
becoming slightly swollen towards the apex. Beneath coarsely, closely punctate. Mesosternum raised 
and anteriorly prominent, feebly arcuate-emarginate in front. Femora obsoletely unidentate, the anterior 
pair almost linear. 
Length 73, breadth 34 millim. (¢?) 
Hab. Nicaraaua, Chontales (Belt). 
One specimen. In this insect the elytra are somewhat gibbous, laterally compressed, 
and narrowed almost from the base, and have a very large, heart-shaped, brownish- 
white patch covering the apical declivity. The ocular lobes of the prothorax are 
feebly developed. 
Species moderately large, convex, elliptic in form, thickly squamose, with the eyes very large 
and narrowly separated, the rostrum curved, the prothorax subconical, the elytral interstices 
almost flat, the mesosternum broad and arcuate-emarginate, the ventral segment 2 nearly 
as long as 3 and 4 united, the femora unidentate. (No. 6.) 
6. Cryptorrhynchus atrosignatus, sp. n. (Tab. XXXI. fige. 13, 13a.) 
Subelliptic, convex, black, the antenne and the tips of the tarsi ferruginous ; Somewhat thickly clothed with 
small, intermixed, white and brownish scales, those on the prothorax rather long and narrow, the white 
scales on the elytra condensed into a sinuous, oblique stripe running from the humeri to near the middle 
of the suture—enclosing a sharply-defined black spot at the base—and continued thence to the apex, 
it being dilated posteriorly and partly surrounding a large oblong blackish patch on the outer part of 
the disc. Head densely punctate, the eyes large and narrowly separated ; rostrum stout, feebly curved, 
not longer than the prothorax, rugosely punctate and subcarinate at the base, the apical half thickly 
punctate, the antenne inserted at the middle, joints 1 and 2 of the funiculus subequal in length, the club 
ovate. Prothorax convex, broader than long, subconical, slightly constricted in front, bisinuate at the 
base ; densely punctate and obsoletely carinate. Scutellum rounded, rugose. Elytra convex, rather 
elongate, laterally compressed, considerably wider than the prothorax, narrowing from a little below 
the base, the humeri rounded ; with rows of oblong, subquadrate punctures, the interstices almost flat, 
rugulose, becoming smoother towards the sides. Beneath coarsely punctate. Legs moderately long, the 
femora feebly clavate and unidentate. 
Length 73, breadth 34 millim. (<¢?) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One rather worn specimen. The elytra in this species have each a sinuous, 
elongate, irregular white streak on the disc, enclosing a sharply-defined black spot at 
the base and partly surrounding an oblong black patch on the outer part of the disc 
towards the apex.
