CYRIONYX. 191 
2. Cyrionyx conotracheloides, sp.n. (Tab. XII. fig. 1.) 
Subrhomboidal, robust, black, variegated above and beneath with a dense clothing of brown and whitish 
scales, the latter condensed into irregular sinuous lines at the sides of the prothorax, and numerous 
small spots on the elytra, the scales on the elytra oval in shape. Head densely, rugulosely punctate ; 
rostrum slightly longer than the head and prothorax, arcuate, rather slender, sparsely, very finely 
punctate, rugulose and sharply carinate at the base, the antenne inserted at a little behind the middle, 
joint 2 of the funiculus shorter than 1. Prothorax strongly constricted in front, the sides parallel at 
the base and obliquely converging anteriorly, the base deeply bisinuate; densely, rugulosely punctate, 
sharply carinate down the anterior half. Scutellum rounded behind, small. Elytra triangular, very 
much wider than the prothorax ; finely punctate-striate, the strise sinuous below the base, the punctures 
oblong and distant one from another, the interstices densely rugulose, 3, 5, 7, and 9 sharply, inter- 
ruptedly, undulato-costate, 6 also costate posteriorly, the elevation below the base of 3 swollen into a 
large, elongate hump, and that near the base of 5 and 7 also much raised. Beneath densely punctate ; 
prosternum deeply and rather broadly sulcate, the anterior coxe narrowly separated. Legs stout; 
femora moderately clavate, the anterior pair feebly, the others more strongly dentate; third tarsal joint 
broadly bilobed, the claws connate at the base. 
Length 5%, breadth 33 millim. (¢?) 
Hab. Mexico (Hoge). 
One specimen, in the collection of Signor A. Solari, of Genoa. The less convex, 
sharply carinate prothorax, the oblong, hump-like prominences on the third and fifth 
elytral interstices below the base, and the more feebly dentate anterior femora distin- 
guish C. conotracheloides from C. reticulatus. The small scutellum and the less clavate 
femora separate both species from the genus Telemus, Pasc.* 
8. Cyrionyx scapulosus. (Tab. XIT. figg. 2, 2a.) 
Centrinus scapulosus, Boh. in Schénh. Gen. Cure. viii. 1, p. 2397. 
Hab. Mexico (ex Afus. Chevrolat 1). 
The type of this species (? 2 ) has been communicated by Dr. Sjéstedt. It is a very 
close ally of C. conotrachelotdes, and differs as follows :—The rostrum is very long and 
slender ; the second joint of the funiculus is much longer than the first; the ridge on 
the third and fifth elytral interstices is uninterrupted, the hump on the third is 
shorter, and that on the fifth is altogether wanting; and the tooth on the anterior 
femora is as sharp as that on the other femora. The two insects may prove to be the 
sexes of the same species, but this is not likely to be the case. 
4, Cyrionyx octocostatus, sp. n. (Tab. XI. figg. 11, 11a.) | 
Rhomboidal, dull, black ; thickly clothed with small, narrow, fulvous scales, with a few ochreous and whitish 
scales intermixed, the ochreous scales on the prothorax clustered into a faint curved band on each side of 
the disc, the whitish scales on the elytra condensed into small spots along the strie, the elytra with a 
large, common, triangular space on the basal half of the disc mottled with black (perhaps due to abrasion 
of the scales) ; the vestiture of the undersurface ochreous and whitish, dense on the pro- and mesopleura, 
that of the femora ferruginous above. Head rugulosely punctate ; rostrum nearly reaching the apex of 
* The femora, as already noted, are dentate in this genus.
