698 . RHYNCHOPHORA. 
Species moderately large, subovate, densely squamose and setulose, with the eyes prominent, 
angular above, the rostrum very stout, short, and arcuate, the antennal club oblong-ovate, 
the prothorax deeply bisinuate at the base and fasciculate on the disc, the elytra sub- 
triangular, with the alternate interstices sharply costate, the mesosternum arcuate- 
emarginate, the ventral segments 2-4 equal in length, the femora unidentate. (No. 125.) 
125. Cryptorrhynchus discedens, sp.n. (Tab. XXXIV. figg. 18, 18a, ¢.) 
Subovate, black,, the antenne ferruginous ; thickly clothed with rather coarse fulvous or rufo-fulvous scales, 
the upper surface slightly mottled with ochreous or whitish (the elytra in one specimen with intermixed 
blackish scales), and also set with short, scattered, semierect, setiform scales, which are clustered into 
six fascicles on the prothorax, the legs variegated with lighter and darker scales. Head rugosely 
punctate, irregularly, transversely carinate or tuberculate in front, the eyes rather prominent, well- 
separated, angular above ; rostrum very stout, short, curved, coarsely, rugosely punctate, swollen at the 
tip in the dg, the apical half smoother in the 9, the antenne inserted beyond the middle, joints 3-7 of 
the funiculus moniliform, 2 shorter than 1, the club stout, oblong-ovate, compact. Prothorax transverse, 
abruptly narrowed and constricted in front; densely punctate, with four setigerous prominences placed 
in a transverse series across the middle and two at the apex. Scutellum small, smooth. Elytra 
somewhat triangular, much wider than the prothorax, the humeri swollen and rather prominent ; 
seriate-punctate, the interstices 3, 5, 7, and 9 sharply costate. Beneath coarsely, closely punctate ; 
mesusternum prominent, arcuate-emarginate. Legs rather short ; femora unidentate. 
Length 5-64, breadth 24-32 millim. (¢ 2.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Two specimens, the female larger and more robust than the male, with the vestiture 
coarser and more variegated, and the femoral teeth larger and blunter. This species 
has somewhat the facies of Oxypterus asper (Boh.). The very short rostrum, which 
is swollen at the tip in the male, separates it from Hubulus. 
Species small, subovate, thickly squamose and setulose, with the rostrum curved, widened 
towards the base, the antennal club oblong-ovate or ovate, the eyes very large, finely 
facetted, and narrowly separated, the prothorax bisinuate at the base, the elytra subtri- 
angular, with the alternate interstices not or moderately raised, the mesosternum very 
prominent, V-shaped in front, the metathoracic episterna broad, the ventral segment 2 
longer than 3, the femora clavate and sharply unidentate, the anterior pair stouter than the 
others. (Nos. 126-180.) | 
126. Cryptorrhynchus scutulatus, sp. n. (Tab. XXXIV. figs. 19,194, ¢.) 
Subovate, nigro-piceous, the antenne ferruginous ; variegated with a dense clothing of intermixed fulvous 
and cinereous scales, the prothorax and elytra here and there mottled or interruptedly reticulate with 
black, the elytra with a dense fulvous spot on each shoulder in front, the legs fusco-annulate ; the upper 
surface also sparsely set with short, erect, setiform scales, which are clustered into four small fascicles 
on the prothorax, two on the disc and two at the apex; the vestiture of the under surface sparse, 
cinereous. Head densely punctate, transversely flattened above the very large, narrowly separated eyes ; 
rostrum strongly curved, a little longer than the prothorax, widened, rugulose, and squamose at the 
base, and for the rest closely, finely punctate, except along the smooth median line, the antenne inserted 
slightly behind the middle, joints 1 and 2 of the funiculus subequal in length, the club oblong-ovate. 
Prothorax transverse, somewhat rounded at the sides, narrowed and feebly constricted in front ; densely 
punctate, feebly binodose on the disc and at the apex. Elytra wider than the prothorax, rather short, 
narrowed from a little below the base; seriate-punctate, the alternate interstices a little raised. Beneath
