670 RHYNCHOPHORA. 
elongate elytra, an oval scutellum, and unarmed femora. The vestiture of the upper 
surface (apart from the large cinereous patch on the elytra) is uniformly blackish, that 
on the scutellum may be a little discoloured. 
68. Cryptorrhynchus caliginosus, sp.n. (Tab. XXXIII. fig. 4, ¢ .) 
Oblong-ovate, black, the antenne and the tips of the tarsi obscure ferruginous ; mottled above with a rather 
dense clothing of intermixed black, brown, and ochreous scales, the ochreous scales condensed into a 
v-shaped mark at the base of the prothorax, various small scattered spots on the basal half of the elytra, 
and a minute isolated spot on the disc of each towards the apex, the scutellum entirely ochreous ; the 
upper surface also set with short, semierect, setiform scales; the vestiture of the legs and under surface 
fulvo-cinereous, the ventral segments with longer piliform scales intermixed, the tibie annulate with 
black. Head rugulosely punctate, the eyes distant; rostrum curved, about as long as the prothorax, 
finely punctate, rugose and feebly carinate at the base, the antenne inserted a little behind the middle, 
joints 1 and 2 of the funiculus equal in length, the club ovate, acuminate. Prothorax broader than long, 
rounded at the sides anteriorly, narrowed and strongly constricted in front; densely, somewhat coarsely 
punctate, and feebly carinate. Scutellum rounded. Elytra moderately long, considerably wider than 
the prothorax, rather convex, narrowing from the middle, the humeri rounded ; seriate-punctate, the 
interstices faintly granulate, 3 and 5 strongly, and 7-9 more feebly, raised. Beneath closely punctate ; 
first ventral segment hollowed down the middle and the fifth shallowly depressed at the apex. 
Mesosternum broad, prominent, arcuate-emarginate. Femora feebly unidentate, the tooth on the 
anterior pair almost obsolete. Tibi nearly straight. 
Length 61, breadth 2% millim. (<¢.) 
Hab. Guatemaua, Cerro Zunil, Pacific slope (Champion). 
One specimen. Near C. collinus, but with the elytra closely mottled with black and 
brown to the apex, with a few small ochreous spots intermixed, the sete shorter 
and coarser. ‘The tooth on the anterior femora is almost obsolete. The scales on the 
abdomen are long, erect, and piliform down the middle. 
69. Cryptorrhynchus octonotatus, sp.n. (Tab. XXXIII. fig. 5, 2.) 
Oblong-ovate, black, the antennz obscure ferruginous ; thickly clothed with small blackish-brown scales, the 
elytra each with two oblique streaks on the disc (one before, the other beyond, the middle), and two 
transverse smaller marks at or near the suture (one at the middle, the other towards the apex), black, 
the scutellum white, the posterior femora and each of the tibie annulate with white, the elytra also with 
small, scattered, semierect scales ; the vestiture of the under surface cinereous and brown’ intermixed. 
Head rugulosely punctate, the eyes well-separated; rostrum not longer than the prothorax, curved, 
slightly widened, rugose, and finely carinate at the base, and for the rest sparsely punctate, the antenne 
inserted behind the middle, joints 1 and 2 of the funiculus subequal in length, the club acute, acuminate. 
Prothorax transverse, gradually narrowing from the base, abruptly narrowed and strongly constricted in 
front; densely, finely punctate. Scutellum rounded. LElytra considerably wider than the prothorax, 
convex, parallel at the base, the humeri rounded and not prominent ; seriate-punctate, 3 and 5 slightly 
raised. Beneath densely punctate. Mesosternum broad, prominent, arcuate-emarginate. Legs rather 
short ; femora feebly unidentate ; tibie straight, subangulate at the base externally. 
Length 53, breadth 23 millim. ( 9.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. The blackish-brown vestiture, the four short, oblique or transverse, 
velvety-black streaks on the disc of each elytron, the white scutellum, the finely
