686 RHYNCHOPHORA. 
elytral interstices; the upper surface also set with long, erect sete, the legs setose. Head densely, 
punctate, the eyes rather large and well-separated ; rostrum short, stout, feebly curved, finely punctate, 
rugulose at the base, the antenne inserted at a little behind the middle, joints 3-7 of the funiculus short, 
2 nearly as long as 1, the club ovate. Prothorax transverse, constricted and narrowed in front; densely, 
finely punctate. Scutellum oval. Elytra considerably wider than the prothorax, narrowing from a little 
below the base, produced at the apex ; punctate-striate, the interstices feebly convex, 3 swollen near the 
base and 2 at the middle. Beneath dull, closely punctate. Mesosternum prominent, broad, feebly 
arcuate-emarginate. Legs rather short ; femora subclavate, sharply unidentate ; tarsi slender. 
Length 22-34, breadth 13-13 millim. (d 9.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Four specimens, varying a good deal in size, the white spots on the elytra conspicuons 
in one only of them. The oblong, blackish elytral prominences—one near the base of 
the third interstice and the other at the middle of the second—are characteristic. The 
femora are more sharply dentate than in C. opaciventris. 
101. Cryptorrhynchus senticosus, sp. n. 
Oblong-ovate, shining, piceous, the elytra more or less mottled with rufo-piceous, the antenne and the tips of 
the tarsi ferruginous ; thickly clothed with brown scales, sometimes with a few whitish scales intermixed, 
the prothorax usually with two small patches at the base and the elytra with a few scattered spots or 
streaks black or blackish; the upper surface also set with rather coarse, erect, scattered sete, the legs 
setose ; the vestiture of the under surface sparse. Head densely punctate, the eyes moderately large and 
well-separated ; rostrum about as long as the prothorax, curved, stout, sparsely punctate, rugulose and 
slightly widened at the base, the apical half smoother in the 9, the antenne inserted at a little behind 
the middle, the club ovate. Prothorax transverse, narrowed and feebly constricted in front; densely 
punctate. Scutellum small. Elytra considerably wider than the prothorax, rapidly narrowing from 
about the middle; punctate-striate, the interstices punctulate and feebly convex. Beneath rather sparsely 
punctate. Mesosternum prominent, arcuate-emarginate. Legs short; femora feebly unidentate ; posterior 
tibie similarly formed in the two sexes, not excavate at the apex in the ¢. 
Length 3-34, breadth 13-13 millim. (do @.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Ten specimens, in rather dirty condition. An obscure species, resembling C. uncipes 
in the colour of the vestiture, but smaller and narrower, the scutellum not so large, the 
legs shorter, the posterior tibiz simple in the two sexes. The allied C. s¢emples is also 
larger, and has larger eyes, longer legs, and the vestiture somewhat differently coloured. 
The larger and more approximate eyes, the longer sete, the non-vittate prothorax, the 
more sparsely punctured ventral surface, and the obsoletely dentate femora distinguish 
C. senticosus from C. tectus. 
102. Cryptorrhynchus contaminatus, sp.n. (Tab. XX XIII. fig. 30, 2.) 
Oblong-ovate, shining, nigro-piceous, the antenne and the tips of the tarsi ferruginous; the prothorax sparsely, 
the rest of the upper surface thickly, clothed with fulvous scales, the elytra with an oblique whitish streak 
on the disc below the base, a broad, angulate, common, post-median, whitish fascia, and some scattered black 
markings, both along the suture (before and beyond the post-median fascia) and on the disc, the scutellum 
whitish ; the upper surface also set with rather long pallid and black sete; the legs setulose, the femora 
subannulate. Head densely, rugulosely punctate, the eyes rather small, distant ; rostrum feebly curved, 
not longer than the prothorax, widened, rugosely punctate, and subcarinate at the base, and for the rest
