264 RHYNCHOPHORA. 
24. Exophthalmus clathratus, sp. n. (Tab. XII. fig. 2, ¢.) 
2. Oblong, moderately broad, black ; thickly clothed (except on the raised portions of the surface) with pale 
green scales, with a few blue scales intermixed on the head and along the suture, the femora and tibiz also 
eeruleo-squamose. Head and rostrum rugulosely punctate, the rostrum a little longer than broad, sulcate 
on each side before the eyes and sharply carinate down the middle, the carina extending forwards to the 
transverse inter-antennal ridge and followed by an oblong inter-ocular fovea; eyes moderately large, 
rounded, convex; antenne rather slender, the scape extending beyond the eyes. Prothorax rather 
convex, a little broader than long, rounded at the sides, slightly hollowed down the middle, feebly 
bisinuate at the base; irregularly reticulato-foveate and with a fine interstitial punctuation, the 
obliquely raised bare ruge very conspicuous. Elytra broad, widening to the middle, acuminate and 
feebly mucronate at the apex; the entire surface reticulate with transversely confluent, sinuous, raised 
bare lines, interrupting the finely punctured strie. 
Length 14, breadth 53 millim. 
Hab. Mexico, Tumbala in Chiapas (flohr). 
One specimen. . Recognizable by the sharply carinate rostrum and the curious 
reticulate sculpture of the elytra, the transverse, confluent, raised, bare lines partly 
enclosing subquadrate or hexagonal viridi-squamose spaces, these becoming smaller 
towards the sides. The scales on the femora and tibie are pale blue, as in various 
species of Compsus. 
25. Exophthalmus vermiculatus, sp. n. (Tab. XII. fig. 3, ¢.) 
Oblong, rather convex, broad ( ¢ ), narrower (d¢), black; densely clothed (except on some of the prominent 
ruge of the upper surface) with whitish, coppery-white, or bluish-grey scales, and also set with a few 
scattered minute hairs. Head and rostrum densely punctate, the rostrum a little longer than broad and 
sharply carinate to the inter-ocular fovea or sulcus; antennal scape reaching the posterior margin of the 
eyes, the latter large and somewhat depressed. Prothorax about as long as broad in dg, a little shorter 
in 9, rounded at the sides, truncate at the base, and hollowed down the middle; coarsely, confluently 
foveolate, the intervening spaces oblique or sinuous and very prominent, and also with a fine dense 
punctuation. Scutellum well developed. Elytra convex, transversely depressed at the base, oblong- 
subtriangular in ¢, broad and widened to the middle in 9, moderately acuminate and without mucro 
at the apex, the humeri obtuse; the rows of punctures interrupted by a network of transversely or 
obliquely confluent.asymmetrical ruge. 
Length 133-15, breadth 42-67 millim. (d @.) 
Hab. Mexico, Chiapas (Sal/é). 
Three specimens. <A very rugose form approaching the Guatemalan EF. cwruleovittatus 
and FE. bilineatus, but with more convex elytra, the scales on the upper surface 
uniformly coloured, the anastomosing ruge partly bare, &c. . vermiculatus has the 
general appearance of a Cleonus. 
26. Exophthalmus ceruleovittatus, sp.n. (Tab. XII. fig. 4, 2.) 
Q. Oblong, black, densely clothed with golden (or golden-green) and blue scales, the latter condensed into 
four vittee on the prothorax (two on the disc and one on each flank) and three stripes on each elytron 
(one near the suture, broad, one at the sides, and one, narrow, along the lower margin), the scales 
around the eyes white, those on the legs and head blue or bluish-green; the surface also set with very 
short, fine, adpressed, scattered hairs. Head and rostrum rugulosely punctate, the rostrum longer than 
broad, finely carinate, the carina followed by a short inter-ocular groove; eyes rounded, convex ; antenne 
rather stout, the scape extending beyond the eyes. Prothorax broader than long, obliquely narrowed
