CYRIONYX. 197 
punctate. Elytra subtriangular, rather convex ; finely punctate-striate, the interstices broad, flat, 
and rugulose. Beneath rather sparsely punctate. Ventral segments 1 and 2 depressed down the 
middle, and 5 with a broad fovea, in the ¢. Anterior coxe well-separated. Femora sharply dentate. , 
Length 21-24, breadth 12-13 millim. (¢ 2.) 
Hab. Guarrmaua, Zapote, Pacific slope (Champion). 
Seven specimens. Smaller and less robust than C. humeralis, the humeri obtuse. 
Larger than 0. nebulosus, the fuscous scales on the prothorax and elytra clustered into 
numerous small scattered spots, the rostrum a little stouter, the prosternal sulcus 
deeper, the anterior coxe less approximate, 
16. Cyrionyx levirostris, sp.n. (Tab. XI. fig. 22.) 
Subovate, obscure ferruginous, the tarsi blackish ; variegated above with a somewhat dense clothing of small, 
sordid ochreous and blackish scales, the dark scales on the elytra mostly clustered into a large, common, 
transverse, subquadrate, interrupted patch at the middle and a transverse space at or below the base, the 
prothorax with two dark vittee on the disc and in one specimen a dark marginal line also; the vestiture 
of the under surface pale and rather close. Rostrum long, moderately curved, thickened at the base, 
smooth and slender in the 92, rugulose at the base and a little stouter in the ¢, the antenne inserted 
behind the middle in both sexes. Prothorax transverse, rounded at the sides from near the base, 
strongly constricted in front; densely, finely punctate. Elytra subtriangular, the humeri rather, 
prominent; finely punctate-striate, the interstices rugulose and almost flat. Beneath closely punctate ; 
prosternum rather deeply suleate ; ventral segment 1 with a broad, smoother, depressed, glabrous space 
extending down the middle in the ¢ and a shallower depression in the 9. Anterior coxs contiguous. 
Legs moderately long ; femora acutely dentate. 
Length 23-22, breadth 14-1} millim. (3 ¢ ») 
Hab. Panama, Volcan de Chiriqui 3000-8000 feet (Champion). 
Two specimens. A species with a long, slender, almost smooth rostrum in the 
male, an irregular, common, transversely-subquadrate, dark patch at the middle of the 
elytra, and two dark vittee on the prothorax, the rest of the vestiture of the upper 
surface close and in great part ochreous. 
17. Cyrionyx fuscitarsis, sp. n. 
Very like C. levirostris, but with the elytral vestiture more mottled, the pallid scales sometimes condensed 
into a large apical patch or a transverse subapical fascia, the prothorax with a median line and a stripe 
midway between it and the margin ochraceous ; the rostrum long, punctate to the tip in the ¢, very 
slender and almost smooth in the Q; the prothorax more rounded at the sides, the anterior portion 
narrow and tubulate ; the anterior coxee narrowly separated. 
Length 22-2,%,, breadth 12-14 millim. (¢ @.) 
Hab. Guatemata, Cerro Zunil (Champion). 
Four specimens. This insect appears at first sight to be nothing more than a 
variety of C. Jevirostris (the elytral markings being variable in both forms), but the 
somewhat thickly punctate rostrum of the male sufficiently distinguishes it. We also 
have a male from Chiriqui that probably belongs to the same species.
