CRYPTORRHYNCHUS. 661 
50. Cryptorrhynchus melancholicus, sp. n. 
Oblong-ovate, dull, black, the antennz and the tips of the tarsi obscure ferruginous ; sparsely clothed with 
blackish scales, with a few fulvous scales intermixed, the latter condensed into three faint interrupted 
lines on the prothorax and a few scattered spots on the elytra; the upper surface also set with short, 
coarse, erect, setiform scales, the legs coarsely setose; the vestiture of the tarsi and under surface pale. 
Head closely punctate, the eyes distant ; rostrum short, stout, arcuate, rugosely punctate to the tip, the 
antenns inserted at the middle, joint 2 of the funiculus shorter than 1, the club ovate. Prothorax 
transverse, rounded at the sides, narrowed in front; closely punctate and feebly carinate, the narrow 
interspaces alutaceous. Scutellum small. Elytra considerably wider than the prothorax, parallel at the 
base, the humeri obtuse ; coarsely seriate-punctate, the interstices closely punctulate and finely granulate, 
all (except the second at the base and the first) more or less raised, 3 swollen below the base. Beneath 
dull, densely punctate. Mesosternum broad, raised, feebly emarginate. Legs rather short, rugose ; femora 
sharply unidentate. 
Length 4, breadth 2 millim. (<.) 
Hab, Panama, Volcan de Chiriqui (Champion). 
One specimen. In this insect the sculpture of the prothorax is not hidden by the 
vestiture; the elytra have the swollen basal portion of the third elytral interstice 
clothed with black scales, and the scattered fulvous scales condensed into a faint 
transverse fascia below this; the legs very rugose and coarsely setose. 
51. Cryptorrhynchus infuscatus, sp. n. 
Oblong-ovate, dull, black, the antenne obscure ferruginous ; thickly clothed with small reddish-brown scales, 
the vestiture of the prothorax blackish, that of its flanks coarser and much paler, the scutellum ochreous, 
the elytra each with an irregular v-shaped, blackish mark on the disc below the base and an angulated 
transverse blackish streak at the middle; the upper surface also set with short dark erect sets, which 
are clustered into six small fascicles on the prothorax (four across the middle and two at the apex), the 
legs strongly setose. Head rugulosely punctate, the eyes rather large, distant; rostrum short, feebly 
curved, slightly widened towards the tip, rugosely punctate throughout, the antenne inserted at about 
the middle, the club ovate. Prothorax broader than long, subquadrate, abruptly narrowed beyond the 
middle, somewhat flattened above; densely, finely punctate, the disc obsoletely carinate and feebly 
binodose. Scutellum rounded. Elytra much wider than the prothorax, parallel in their basal half, the 
humeri obtuse; seriate-punctate, the interstices punctulate and feebly granulate, 3 interruptedly raised 
to about the middle, 5 and 7 also prominent. Beneath dull, closely punctate. Mesosternum broad, 
prominent, feebly arcuate-emarginate. Legs rather short ; femora sharply unidentate. 
Length 5, breadth 23 millim. (¢?) 
Hab. Panama, Bugaba (Champion). 
One specimen. The abruptly narrowed, fasciculate prothorax, the rugose rostrum, 
the irregular, angulate, blackish-brown markings on the basal half of the elytra, the 
dull surface, the sharply dentate femora, &c., distinguish C. infuscatus. 
52. Cryptorrhynchus fraterculus, sp.n. (Tab. XXXII. fig. 21, 3.) 
Subovate, opaque, black, the antenne obscure ferruginous ; variegated above with rather coarse fulvous, black, 
cinereous, and whitish scales, the whitish scales condensed into an oblique streak on each elytron below 
the base, the eiytra also somewhat thickly set with short, stiff, erect sete, and the prothorax with 
numerous erect, intermixed, black, setiform scales; the vestiture of the legs and underface close and 
coarse, the legs fusco-annulate and setulose. Head rugosely punctate, the eyes widely separated; 
rostrum short, stout, feebly curved, rugosely punctate and carinate in the ¢, sparsely punctate from
