CRYPTORRHYNCHUS. 685 
98. Cryptorrhynchus opaciventris, sp. n. 
Oblong-ovate, piceous, the antenne and the tips of the tarsi ferruginous; somewhat thickly clothed with 
small pale brown scales, with cinereous scales intermixed, the elytra mottled with black; the upper 
surface also set with erect sets, the legs setose; the vestiture of the under surface sparse. Head densely 
punctate, the eyes moderately large and well-separated ; rostrum short, feebly curved, slightly widened 
at the base, rugosely punctate to the tip in the ¢, much smoother in the 9, the antenne inserted at or 
a little behind the middle, joint 2 of the funiculus shorter than 1, the club ovate. Prothorax transverse, 
somewhat rounded at the sides, narrowed and feebly constricted in front; densely punctate. Scutellum 
small. LElytra considerably wider than the prothorax ; punctate-striate, the interstices feebly convex, 
3 slightly swollen at the base. Beneath opaque, alutaceous, finely punctate. Mesosternum raised, 
prominent, feebly emarginate. Legs short; femora acutely unidentate, the tooth on the anterior pair 
narrow ; tarsi slender. 
Length 34, breadth 1} millim. (¢ @.) 
flab. Panama, Volcan de Chiriqui (Champion). 
One pair. Near C. simplex, but smaller, the eyes not so large and more distant, the 
under surface opaque and alutaceous, the third elytral interstice slightly swollen at 
the base. The elytral striz are less coarsely punctate than in C. echinatus, and the 
sete are shorter and finer than in that insect. 
99. Cryptorrhynchus disjunctus, sp. n. 
Oblong-ovate, shining, piceous, the antenne ferruginous; clothed with small brown scales, the prothorax 
with two curved blackish marks on the disc behind and a minute whitish spot in front of the scutellum, 
the latter ochreous, the elytra with a black spot on the third interstice below the base and a whitish 
one on the second beyond the middle; the upper surface also set with short, erect, light and dark sete, 
the legs setose ; the vestiture of the under surface sparse and pale. Head densely punctate, the eyes 
rather large and somewhat distant; rostrum short, stout, feebly curved, sparsely, minutely punctate, 
rugulose at the base, the antenne inserted at about the middle, joint 2 of the funiculus much shorter 
than 1, the club ovate. Prothorax transverse, constricted and much narrowed in front; densely punctate. 
Elytra considerably wider than the prothorax, rapidly narrowing from about the middle; punctate- 
striate, the interstices punctulate, 3 swollen just below the base. Beneath rather closely punctate. 
Mesosternum prominent, arcuate-emarginate. Legs short; femora unidentate. 
Length 44, breadth 2 millim. (2.) 
Hab, Panama, Volcan de Chiriqui (Champion). 
One specimen. Near C. guadrituberculatus, but with an oblong black prominence at 
the base of the third elytral interstice only (the one on the second interstice wanting), 
the second with a sharply-defined whitish spot beyond the middle, C. guttatus is 
marked in the same way, but that insect wants the black patch on the third elytral 
interstice, and has the second interstice swollen to near the middle, the prothorax 
binodose at the apex, &c. 
100. Cryptorrhynchus quadrituberculatus, sp. n. (Tab. XXXIII. 
fic. 29, 2.) | 
” Oblong-ovate, shining, piceous, the antenne and the tips of the tarsi ferruginous; somewhat thickly clothed 
with small fulvous scales, variegated with blackish and white scales, the latter condensed into two 
irregular, curved series of spots on the disc of the elytra, the blackish scales mainly clustered into two 
spots at the base of the prothorax and an oblong spot on the swollen portion of the second and third
