646 RHYNCHOPHORA. 
antenne inserted at about the middle, joints 1 and 2 of the funiculus subequal in length, the club ovate. 
Prothorax transverse, rounded at the sides, narrowed and feebly constricted in front; coarsely, densely 
punctate, obsoletely carinate anteriorly. Scutellum small, rounded, convex. Elytra much wider than 
the prothorax, flattened on the disc, narrowing from about the basal third, compressed at the sides before 
the apex; coarsely seriate-punctate, the interstices rugulose and almost flat. Beneath very coarsely 
punctate. Mesosternum horseshoe-shaped. Legs stout; the femora subclavate and feebly unidentate. 
Length 7-72, breadth 3,31 millim. (9.) 
Hab. Guatemata, Panzos (Champion) ; Nicaragua, Chontales (Beit). 
Two specimens, assumed to be females. Near C. bicruciatus, but with the head foveate 
between the eyes, the elytra flattened on the disc, compressed at the sides before the 
apex, and differently marked, the femoral tooth smaller, the ventral segments more 
coarsely punctate, the mesosternum horseshoe-shaped. 
Species moderately large, robust, ovate or oblong-ovate, thickly or sparsely squamose, with the 
eyes large and partly or quite covered in repose, the rostrum curved, the prothorax rounded 
at the sides and bisinuate at the base, the elytral interstices finely seriato-granulate and 
rather convex, the mesosternum arcuately or subangularly emarginate, the ventral segment 2 
longer than 3, the femora unidentate, the anterior tarsi of the ¢ (except in C. alutaceus) 
clothed with long, scattered, projecting hairs. C. scopulatus and C. plagiaticollis might 
perhaps be included under Cophes. (Nos. 23-25.) 
23. Cryptorrhynchus scopulatus, sp.n. (Tab. XXXI. fig. 28, 3.) 
Oblong-ovate, robust, moderately shining, black, the antennew obscure ferruginous ; thickly clothed above with 
rather coarse, intermixed whitish, reddish-brown, and blackish scales, the latter condensed into two 
subtriangular patches at the base of the prothorax and various irregular or interrupted, common, trans- 
verse fascie on the basal two-thirds of the elytra, the humeri pale, the vestiture of the under surface 
sparse, that of the legs close and pale, the tibie fusco-annulate. Head closely punctate, the eyes very 
widely separated; rostrum moderately stout, feebly curved, about as long as the prothorax, rugosely 
punctate and carinate in its basal half, and somewhat coarsely punctured thence to the tip, smoother in 
the 2, the antenne inserted at about the middle, joints 1 and 2 of the funiculus subequal in length, the 
club ovate. Prothorax a little broaderthan long, narrowed from the middle, and feebly constricted in 
front, the ocular lobes prominent; densely punctate and finely granulate. Scutellum small. Elytra 
slightly wider than the prothorax, narrowing from before the middle, the humeri obtuse ; seriate-punctate, 
the interstices somewhat convex, punctulate, and seriato-granulate. Beneath very coarsely punctate. 
Mesosternum prominent, horseshoe-shaped. Legs rather stout; femora feebly clavate, unidentate ; 
anterior tibie sinuous within; anterior tarsi of the ¢ with joints 1 and 2 slightly dilated and clothed 
with numerous long projecting hairs. 
Length 7-74, breadth 34-31 millim. (¢ 9.) 
Hab. Muxtco, Toxpam (Sallé), Jalapa (Hége). 
One pair, both from the Atlantic slope. The following isan allied form. There 
are no sete on the prothorax or elytra. 
24, Cryptorrhynchus plagiaticollis, sp.n. (Tab. XXXI. figg. 29, 29a, ¢.) 
Ovate, robust, dull, black, the antennzs fusco-ferruginous, thickly clothed above with rather coarse reddish- 
brown scales, a space at the hind angles of the prothorax paler, the prothorax with two subtriangular 
black patches on the disc at the base, and the elytra with various irregular markings on the basal 
two-thirds, a subtriangular patch on the suture at the apex, and sometimes a small spot on each side of
