260 RHYNCHOPHORA. 
Fifteen examples. This species has the facies of a Compsus, but it is really related 
to FE. impositus (Pasc.), having a similarly formed rostrum, &c. The irregular scattered 
bare transverse scratches on the prothorax and elytra give the insect a peculiar 
appearance; the eyes, too, are depressed, the rostrum short and arcuately carinate, 
and the vestiture of the elytra is so dense as to make the seriate punctures appear 
quite small.

Prepodes nubilus, Rosensch. in Schonh. Gen. Cure. vi. 1, p. 355°. 
Naupactus aurivittis, Sturm, in litt.’. 
Prothorax with a cupreous or coppery-white stripe on each side, and the elytra each with two similarly- 
coloured stripes—one on the disc, sometimes evanescent or interrupted, the other along the lower 
margin—the space between them bluish. Rostrum finely carinate to the inter-ocular fovea; eyes 
moderately prominent ; prothorax hollowed down the middle and towards the sides, impressed with 
coarse, scattered, irregularly distributed punctures; elytra narrowed towards the base in both sexes, 
broad and widened to the middle in 2, narrower in ¢, the humeri not very prominent, punctate- 
striate, the third interstice (beyond the middle) and the fifth interstice (at the basal third) irregularly 
foveate, the depressions in some examples diverting the strie and in others smoother and bare; anterior 
tibie feebly unguiculate ; body winged. 
Length 10-13, breadth 33-5, millim. (¢ 9.) 
Hab. Mexico? (Sturm, in coll. Sallé; Mus. Brit.), between Acapulco and Oaxaca!, 
I have seen seven specimens of this species (five of which belong to the Sommer 
collection), one only of which bears a locality-label ‘“ Oaxaca.” The females have the 
vestiture between the dorsal vitte of the elytra more or less cupreous, so that the 
stripes are less distinct in this sex than in the males. The foveiform depressions on 
the disc of the elytra (which are sometimes bare and almost smooth) are very similar 
to those of E. agrestis and E. distigma. 
17. Exophthalmus scalaris, (Tab. XI. fig. 25, ¢.) 
Prepodes scalaris, Boh. in Schénh. Gen. Cure. vi. 1, p. 849°. 
Chlorima hieroglyphica, Sturm, Cat. 1826, p. 115’. 
Oblong, rather narrow (¢), broad (2), black; above densely clothed with yellowish-white scales, the 
prothorax with three narrow vitte (the central one evanescent), and the elytra with a marginal stripe 
of variable length (and in the ¢ the suture also), more sparsely set with smaller white or bluish-white 
scales, similar to those on the under surface and legs; the dense vestiture more or less coated with 
a powdery yellowish exudation ; the elytra with a transverse or oblique spot on the dise at about the 
basal third, another within the shoulder, and three or four small spots beyond the middle, bare. 
Rostrum longer than broad, flattened, rugulosely punctate, neither carinate nor sulcate; eyes large, 
rounded, moderately prominent. Prothorax short, strongly bisinuate at the base, densely, tinely punctate. 
Elytra elongate triangular ( ¢), much broader and widened to the middle in 9, mucronate at the tip, 
.the humeri prominent ; punctate-striate, the outer interstices convex, 8 abruptly bifurcate at the middle 
and partly enclosing the two supplementary strie, the bare spots almost smooth. Anterior tibic feebly 
denticulate and strongly unguiculate. 
Length 94-133, breadth 33-54 millim.
