204. RHYNCHOPHORA. 
Three specimens. The conical, fusco-bivittate prothorax, the dense, squamiform, 
mottled vestiture of the elytra, and the long rostrum characterize C. sguamans. The 
elytra are somewhat rounded at the sides. ‘The conical prothorax and the subcontiguous 
anterior coxe separate the present species from C. twrbidus, which in other respects is 
very similar. | 
33. Cyrionyx nebulosus, sp. n. 
Ovate, piceous, the antenne, femora, and tibie, and sometimes the rostrum also, reddish or ferruginous ; 
densely squamose, the scales on the elytra oval and somewhat imbricate, those on the under surface also 
coarse: varying in colour above according to the predominance of the brown or of the whitish scales, the 
brown scales on the prothorax condensed into two vitte on the disc (sometimes reduced to four spots) and 
a marginal stripe, the elytra clouded with brown and white, the white scales on the elytra usually 
condensed into a short streak on the fourth interstice below the base and a patch on the disc at about 
one-third from the apex; the vestiture of the under surface entirely whitish. Rostrum feebly arcuate, 
moderately stout, long, in the 9 nearly reaching the apex of the metasternum, thickly, finely punctate, 
the apical half smoother, especially in the @, the antenne inserted behind the middle. Prothorax 
transverse, rounded at the sides, constricted and much narrowed in front, bisinuate at the base ; densely, 
finely punctate. Scutellum small. Elytra considerably wider than the prothorax, the humeri not 
prominent; finely punctate-striate, the interstices flat and densely punctulate. Beneath closely punctate ; 
ventral segments 1 and 2 shallowly depressed down the middle in the g, Femora each with an 
acute tooth. 
Length 13-23, breadth 1-1} millim. (¢ 9.) 
Hab. Mexico, Playa Vicente (Sallé), Teapa (H. H. Smith); Brrmisu Honpvuras, Rio 
Sarstoon (Blancaneaux); GuateMata, Cahabon, San Juan, La Tinta, Tamahu, and 
Purula in Vera Paz (Champion); Panama, Volean de Chiriqui, Caldera, Taboga I. 
(Champion). 
Apparently a common insect in Central America, and varying in the markings of 
the upper surface. ‘The elytra are more finely striate than in C. turbidus, and the 
vestiture is closer, the darker scales not clustered into numerous small spots. 
general shape C. nebulosus is more ovate than the allied forms. 
In its 
34. Cyrionyx fuscovarius, sp. n. 
Very like C. nebulosus and differing as follows:—The vestiture dense, yellowish-white, the upper surface 
faintly mottled with white, the prothorax with four small fuscous spots on the disc, the elytra variegated 
with irregular, sharply-defined, fuscous markings, an oblong patch near the suture below the base larger 
than the rest; the prothorax obliquely narrowing from the base, 
Length 1-22, breadth 14-14 millim, (¢ 9.) 
Hab. Guatemaua, San Gerénimo and Capetillo ( Champion). 
The description is taken from three specimens from San Gerénimo, the single 
example, from Capetillo, being worn.
