658 RHYNCHOPHORA. 
of the under surface paler, that of the femora and tibie dense, coarse, and setiform, fuscous and whitish 
intermixed, the tibia annulate with whitish towards the tip. Head densely punctate, the eyes widely 
separated ; rostrum rugulosely punctate and carinate, the apical half coarsely punctate, smoother in the 2, 
joints 1 and 2 of the funiculus equal in length. Prothorax much broader than long, abruptly narrowed 
in front, the sides rounded anteriorly and parallel behind; densely, finely punctate, and also carinate. 
Scutellum rather small. Elytra much wider than the prothorax, parallel in their basal half; alutaceous, 
seriate-punctate, the interstices seriato-granulate, 2 and 3 interruptedly costate, 3 and 5 also raised at the 
base, and the others convex towards the sides or apex. Beneath alutaceous, densely, shallowly punctate. 
Legs rugosely punctate, the femora acutely unidentate. 
Length 53-83, breadth 24-4 millim. (¢ @.) 
Hab. Nicaraeva, Chontales (Belt, Janson). 
Three specimens, varying greatly in size. Distinguishable from the allied forms 
with all the elytral interstices granulate by the transverse white spot on the disc of 
each elytron towards the apex, and from C. alboscutellatus by the smaller scutellum and 
the more convex prothorax. . 
44. Cryptorrhynchus patruelis, sp. n. 
Oblong-ovate, opaque, black, the antenne and the tips of the tarsi ferruginous ; somewhat thickly clothed with 
intermixed reddish-brown and black scales, the black scales on the prothorax condensed into two curved 
lines on the dise and another on each side, and those on the elytra clustered into various irregular patches, 
the upper surface also rather closely set with coarse sete ; the femora and tibiz coarsely, densely setose, 
subannulate. Head densely punctate, the eyes widely separated ; rostrum stout, about as long as the 
prothorax, rugosely punctate to the tip in the ¢, the apical half shining and more sparsely punctate in 
the @. Prothorax transverse, much narrowed in front ; densely punctate, slightly depressed down the 
middle and also towards the sides, and with an indistinct median carina. Scutellum small. Elytra wider 
than the prothorax, parallel in their basal half; seriate-punctate, the interstices uneven and very sparsely 
granulate, 2, 3, and 5 interruptedly raised, the outer ones more or less convex, the suture flattened 
throughout. Beneath densely punctate. Mesosternum broad and very prominent, arcuate-emarginate. 
Legs rugulosely punctate, the femora unidentate. 
Length 5-6, breadth 21-24 millim. (¢ 2.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Four specimens. Very like C. rugipes, but wanting the white spots on the elytra, 
the rostrum rugose to the tip in the male, the prothorax more uneven, nigro-maculate, 
the elytra obsoletely granulate, the suture flattened throughout. 
45. Oryptorrhynchus coriarius, sp.n. (Tab. XXXII. fige. 17, 17 a.) 
Subovate, opaque, black, the antenne ferruginous ; thickly clothed with intermixed reddish-brown, blackish, 
and ochreous (or cinereous) scales, the head sometimes with a whitish median line extending on to the 
‘anterior margin of the prothorax, the scutellum whitish, the elytra sometimes with a curved, oblique, 
ochreous humeral streak, the upper surface also somewhat thickly set with short, semierect, coarse sete, 
these becoming blackish and fasciculate on the prothoracic elevations, the legs setulose and subannulate 
with ochreous or whitish. Head rugulosely punctate, flattened between the widely separated eyes ; 
‘rostrum stout, feebly curved, scarcely as long as the prothorax, rugosely punctate, striate at the base, 
more finely punctate in the 2, the antenne inserted behind the middle, joint 2 of the funiculus shorter 
than 1, the club ovate. Prothorax transverse, constricted and much narrowed in front ; densely, finely 
punctate, with four, more or less distinct, transversely placed, setigerous prominences placed transversely 
across the middle and two others at the apex. Scutellum rounded. Elytra mueh wider than the 
prothorax, subparallel in their basal half, the humeri obtuse ; serlate-punctate, the interstices rugulose and
