CRYPTORRHYNCHUS. 645 
along the centre, the antenne inserted beyond the middle, stout, joints 3-7 of the funiculus equal in 
length, 2 shorter than 1, the club short-ovate. Prothorax transverse, rounded at the sides, narrowed 
and feebly constricted in front; very coarsely, closely punctate. Scutellum small, tuberculiform. 
Elytra much wider than the prothorax, subparallel in their basal half; very coarsely seriate-punctate, 
the interstices finely punctate, becoming feebly convex towards the sides, the fifth slightly raised at its 
apex. Beneath coarsely punctate. Mesosternum broad, arcuate-emarginate. Legs very stout, short, the 
femora unidentate, the tibie sinuate within. 
Length 74-8, breadth 34-3? millim. (9 ?) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Two specimens. A species of oblong-ovate form, coarsely squamose and coarsely 
punctate, the elytra with peculiar markings, the legs short, stout, and densely squamose, 
the rostrum short, stout, and almost bare. 
21. Cryptorrhynchus bicruciatus, sp.n. (Tab. XXXI. figg. 26, 26 a.) 
Oblong-ovate, robust, dull, black (the elytra piceous in one specimen), the antenne and the apical half of the 
rostrum more or less ferruginous; the prothorax and the ventral segments sparsely, and the rest of 
the surface thickly, clothed with coarse, ochreous (or whitish) and fulvous scales, the scales on the 
prothorax condensed into an irregular, double, cruciform patch on the disc, the elytra each with an 
oblique patch on the dise at the base, a spot near the suture at about the middle, a large, interrupted, 
subtriangular space exterior to this, and some irregular spots at the apex, black, the tibia each with a 
blackish spot on the outer edge near the base, the elytra also set with coarse, seriately arranged, raised 
scales. Head rugosely punctate, carinate in the middle between the eyes, the latter large, depressed, and 
widely separated ; rostrum curved, not reaching the metasternum, shining, sparsely, finely punctate, the 
punctures becoming coarser and seriately arranged at the base, the antenne inserted at about the middle, 
joints 1 and 2 of the funiculus equal in length, the club ovate. Prothorax broader than long, rounded at 
the sides, constricted and narrowed in front ; coarsely, rugosely punctate, and with a short median carina. 
Scutellum rounded. LElytra a little wider than the prothorax, subparallel in their basal half, the humeri 
obtuse; coarsely seriate-punctate, the interstices from the base to the apical declivity (the sutural one 
excepted) convex and seriato-granulate. Mesosternum prominent, arcuate-emarginate. Ventral segments 
sparsely, shallowly punctate. Legs short, very stout, the femora feebly clavate and sharply unidentate. 
Length 63-8, breadth 3-34 millim. (2.) 
Hab, Guatemata, Teleman and Panzos in the Polochic Valley (Champion). 
Two specimens. In this insect the light-coloured scales are condensed into a 
+¢-shaped mark on the disc of the prothorax, and a large, irregular, common, X-shaped 
patch on the elytra. The convex, granulate, dorsal interstices of the elytra separate it 
from most of the allied forms. The tibia have a black spot on the outer edge near 
the base, as in C. v-nigrum. 
22. Cryptorrhynchus octomaculatus, sp.n. (Tab. XXXI. figg.27, 27a, 2.) 
Oblong-ovate, rebust, black, the antennz fusco-ferruginous; the head, prothorax, and under surface sparsely, 
the elytra and legs thickly, clothed with coarse whitish and pale reddish-brown scales, the scales 
condensed into three faint, evanescent vittz on the prothorax, the elytra each with a short streak on the 
third interstice at the base, another at about the middle, an oblong patch on the outer margin exterior 
to this, and a triangular lateral spot before the apex, black, the tibiz annulate with black near the base, 
the elytra also set with coarse, seriately arranged, raised scales. Head coarsely, closely punctate, deeply 
foveate between the widely separated, depressed eyes ; rostrum stout, nearly reaching the metasternum, 
feebly curved, shining, sparsely punctate, the punctures subseriately arranged towards the base, the
