CRYPTORRHYNCHUS. 663 
above. It approaches C. rugipes, but the rostrum is more rugose in both sexes, and 
the vestiture is differently coloured. 
55. Cryptorrhynchus cinereus, sp.n. (Tab. XXXII. fig. 24.) 
Oblong-ovate, black, the antenne and tarsi ferruginous; thickly clothed with rather coarse cinereous scales, 
the prothorax, a broad space across the middle of the elytra, and the third interstice below the base, 
more or less mottled with blackish-brown, the elytra also set with short, scattered, suberect, setiform 
scales, the femora and tibiz fusco-annulate. Head densely, rugulosely punctate, the eyes widely separated ; 
rostrum stout, feebly curved, scarcely so long as the prothorax, rugosely punctate, the punctuation 
becoming sparser and finer at the middle, the antenne inserted midway, joints 1 and 2 of the funiculus 
equal in length, the club ovate. Prothorax slightly broader than long, rounded at the sides, feebly 
constricted and much narrowed in front; densely, rather finely punctate and obsoletely carinate. 
Seutellum rounded. Elytra considerably wider than the prothorax, subparallel in their basal half, the 
humeri obtuse; seriate-punctate, the interstices rugulose and finely granulate, 2-9 more or less raised, 
3 somewhat swollen below the base. Beneath densely punctate. Mesosternum raised and very 
prominent, feebly emarginate. Legs rather short ; femora feebly unidentate. 
Length 54, breadth 23 millim. (d ?) 
Hab. Nicaragua, Chontales (Belt). 
One specimen. In this species the dark markings on the elytra tend to form a 
broad interrupted median fascia and a spot on the third interstice below the base, the 
rest of the elytral vestiture being cinereous. The entire under surface is very 
densely punctate. The more feebly dentate femora and the very differently coloured 
vestiture separate it from C. tenebrosus. 
56, Cryptorrhynchus albopunctatus, sp.n. (Tab. XXXII. figg. 25, 25a, @ .) 
Oblong-ovate, opaque, black, the antennz fusco-ferruginous ; densely clothed with dark brown scales; the 
elytra with an oblique band of small whitish spots extending from below the humeri to the second 
row of punctures and a few whitish spots at the sides beyond the middle, and also with a velvety- 
black patch at the base and another at the middle of the disc, the scutellum ochreous or whitish, the 
vestiture of the under surface and legs brownish-white, the femora and tibiz annulate with brown; the 
upper surface also set with very short, dark, scattered, setiform scales, the legs setulose. Head densely 
punctate, the eyes pyriform, large, lateral ; rostrum feebly curved, stout, not longer than the prothorax, 
widened towards the base, rugosely punctate and subcarinate, in the 2 straighter and more sparsely 
punctured, the antenne inserted towards the base, joints 1 and 2 of the funiculus subequal in length, 
the club stout, short ovate. Prothorax transverse, rounded at the sides, feebly constricted and much 
narrowed in front, bisinuate at the base; densely, finely punctate, and subcarinate. Scutellum oval. 
Elytra much wider than the prothorax, sinuate at the base, parallel in their basal third, flattened along 
the suture, the humeri obliquely truncated in front; seriate-punctate, the interstices densely rugulose 
and with a few scattered granules, 3 and 5 interruptedly raised to about the middle, the outer ones 
somewhat convex, the others flat. Beneath densely punctate. Mesosternum broad and prominent, 
arcuate-emarginate. Legs moderately stout, rugosely punctate ; femora ciavate, very sharply unidentate ; 
tibiz broad, sinuous within. 
Length 63-72, breadth 2%,-33 millm. (d 2.) 
Hab. Mexico (ea coll. Flohr); Nicaraaua, Chontales (Belt, Janson). 
Four specimens from Mexico and two from Nicaragua. ‘This species approaches the 
genus Cnemargus, but it has the mesosternum formed very much as in Gasterocercus.
