CRY PTORRHYNCHUS. 639 
Species moderately large, elongate, densely squamose, with the head convex, the rostrum curved, 
the eyes distant and partly covered in repose, the antennal club ovate, the scutellum filling 
the cavity, the prothorax bisinuate at the base, the elytra oblong, with the alternate 
interstices narrowly costate, the mesosternum horseshoe-shaped, the ventral segments 2-4 
equal in length, the femora unidentate. (No. 11.) 
11. Cryptorrhynchus crotonis, sp. n. (Tab. XXXI. figg. 17, 174, ¢.) 
Elongate, black or piceous, the antenne obscure ferruginous; densely clothed above and beneath with 
intermixed pale brown and whitish scales, the latter condensed into numerous small patches on the 
elytra, the entire surface also set with short, scattered, setiform scales. Head densely, rugulosely 
punctate, the eyes large and widely separated ; rostrum stout, curved, about as long as the head and 
prothorax, depressed at the base, densely punctate and unicarinate to about the middle, and thickly 
punctate (except along the centre) thence to the apex, the apical half a little smoother in the 9, the 
antennee inserted about midway, joint 2 of the funiculus shorter than 1, the club ovate. Prothorax 
broader than long, abruptly narrowed and constricted in front, the sides rounded anteriorly, the base 
bisinuate; densely, finely punctate and obsoletely granulate. Scutellum rounded, rugulose. Elytra 
long, a little wider than the prothorax, parallel in their basal third, flattened on the disc anteriorly ; 
seriate-punctate, the interstices densely rugulose, 3, 5, 7, and 9 narrowly, feebly costate. Beneath 
densely, finely punctate. Legs moderately long ; femora clavate, sharply unidentate. 
Length 62-83, breadth 24-33 millim. (¢ 9.) 
Hab. Costa Rica, Escazu, San José (Biolley). 
Five specimens, four of which are labelled as having been found on the trunk of a 
Croton; one of them (evidently discoloured) has the vestiture almost entirely 
brown. This insect is of about the same size and shape as Africhis occiduus, but 
the vestiture is denser and not so coarse, the eyes are broader, the legs are longer 
and more slender, the anterior femora are unidentate, the ventral segments 2—4 are 
equal in length, &c. 
Species moderately large, elongate-elliptic, sparsely squamose, with the rostrum arcuate, the 
antennal club ovate, the prothorax and elytra almost equal in width, the mesosternum 
horseshoe-shaped, the metathoracic episterna very broad, the ventral segment 2 longer 
than 3, the femora clavate and dentate, the tibize carinate. (No. 12.) 
12. Cryptorrhynchus xqualis, sp.n. (Tab. XXXI. figg. 18, 18a; 184 
front leg.) 
Moderately elongate, subelliptic, rather convex, shining, rufo-piceous; above uniformly clothed with small fulyous 
scales, the vestiture of the abdomen very sparse, fine, and piliform, Head rugulosely, the flattened intraocular 
space coarsely, punctate, the eyes large, distant ; rostrum stout, curved, reaching to about the middle of 
the intermediate cox, very sparsely, minutely punctate, punctate-striate and carinate on each side at 
the base, the antenne inserted at about the basal third, joints 1 and 2 of the funiculus subequal in length, 
the club ovate. Prothorax broader than long, arcuately narrowing from about the middle, feebly 
constricted in front, the apex somewhat produced above; densely, rugulosely punctate, the anterior lobe 
smoother. Scutellum small, prominent. LElytra oblong, parallel in their basal half, very little wider 
than the prothorax, produced at the apex; coarsely seriate-punctate, the interstices rugulose and 
obsoletely granulate, 3-9 narrowly raised. Mesosternum very prominent, horseshoe-shaped. Ventral 
segments 1-4 almost smooth, except at the sides, 5 coarsely punctate. Legs stout, short, the anterior
