RHYNCHOPHORA. 485 
constricted in front; densely, finely punctate. Elytra much wider than the prothorax, triangular, rather 
convex; finely punctate-striate, the interstices almost flat, densely punctate, Femora unidentate. 
Tarsal claws minute, free. . 
Length 2, breadth 1,1, millim. 
Hab. Guaremata, Trece Aguas in Alta Vera Paz (Barber §& Schwarz, in U.S. Nat. 
Mus.). 
One specimen, in good condition; a worn example from the same locality, with the 
white scales much less numerous, and not clustered into definite markings, probably 
belonging to the same species. Near C. alboplagiatus, but with the white markings 
less sharply defined and differently placed (there being no trace of a spot on the 
second elytral interstice below the base), the purplish-brown scales larger and more 
numerous ®. The scales are smaller and less rounded on the elytra than in the 
variable C. nebuiosus. | 
Cyrionyx nebulosus (p. 204). |

* The following is another allied form from the Lesser Antilles :-— 
Cyrionyx alboguttatus, sp. n. | 
Subrhomboidal, narrow, moderately shining, piceous, the legs obscure ferruginous in one specimen ; variegated 
above and along the sides beneath with dense spots and patches of pure white scales, the white scales on 
the prothorax condensed into three more or less interrupted lines, and those on the etytra into a 
transverse patch at the shoulder, an interrupted band below it (extending from the fifth stria to the 
margin), an oblong spot on the second interstice at about one-fourth from the base, a larger spot on the 
dise towards the apex, and an oblique, anteriorly bifurcate streak at the tip; the rest of the upper 
surface clothed with smaller blackish, and that of the under surface with white, scales; the legs albo- 
squamose. Head densely punctulate and squamose between the large eyes; rostrum curved, moderately 
stout, a little longer than the head and prothorax. Prothorax short, rounded at the sides, narrowing from 
near the base, constricted in front; densely, finely punctate. Elytra much wider than the prothorax, 
rather convex, triangular ; deeply punctate-striate, the interstices feebly convex and closely punctate. 
Legs long and slender ; femora unidentate ; tarsal claws very small, free. 
Length 13, breadth 1 millim. 
Hab. St. Vincent, Leeward side. 
Two specimens. Very like C. alboplagiatus and C. sexguttatus, but with numerous sharply-defined pure 
white spots above and beneath, much as in C. semicostatus, an insect with the elytral interstices sharply 
raised posteriorly.
