200 RHYNCHOPHORA. 
first placed close to the suture, the interstices smooth and flat. Ventral segments very sparsely punctate. 
Legs elongate, slender; femora acutely dentate; tibia sharply unguiculate, 
Length 24, breadth 1 millim. (9 ?) 
Hab. Panama, Bugaba (Champion). 
“One specimen. Distinguishable by the long, triangular, shining elytra, with small 
scattered patches of pure white scales near the base and apex, deeply-cut strie, and 
smooth, flat interstices ; the long, slender legs, &c. 
23. Cyrionyx apiatus, sp.n. (Tab. XI. fig. 27.) 
Subovate, rather shining, varying in colour from piceous, with. the antenne, elytra, and legs ferruginous, to 
entirely ferruginous; the vestiture very fine and sparse, ochraceous and ferruginous, the prothorax 
usually with one or two small white spots on each side and sometimes a faint whitish median line, the 
elytra with several small patches of coarser pure white scales—a spot on the second interstice below the 
base, a transverse mark at the sides in a line with it, and a spot on the disc towards the apex; the 
under surface and legs with scattered whitish scales. Rostrum stout, strongly arcuate, rugulosely 
punctate and feebly carinate, sparsely punctate at the tip, a little smoother in the 2, the antenne 
inserted beyond the middle. Prothorax transverse, rounded at the sides, constricted in front; densely, 
finely punctate. Elytra subtriangular, the humeri somewhat prominent ; very deeply striate, the strix 
feebly punctate and nearly as broad as the interstices, the latter narrow, convex, becoming subcostate 
towards the apex, and more or less punctulate. Beneath closely punctate ; ventral segment 1 broadly 
_ depressed down the middle in the g. Legs rather long; femora acutely dentate, 
Length 13-2,),, breadth 1-1, millim. (3 9.) 
- Hab. Mexico, Teapa (H. H. Smith); Guatumata, San Juan and Senahu in Vera 
Paz (Champion). 
Ten specimens, varying in colour (though the elytral spots are constant in position, 
and do not reach the base) and in the intensity of the puncturing of the elytral 
interstices. The broadly and deeply striate elytra, and the arrangement of the 
vestiture of the upper surface, separate C. apiatus from C. sexguttatus and C. clathratus. 
The rostrum is stout and comparatively short. 
24, Cyrionyx clathratus, sp.n. (Tab. XI. figg. 28, 28a, 3.) 
Subovate, rather narrow, nigro-piceous, the antennze obscure ferruginous ; the prothorax with intermixed white 
and ochreous, hair-like scales, the white scales condensed into three lines on the disc and a transverse streak 
on the flanks near the anterior margin, and the ochreous scales into a faint transverse fascia across the 
middle of the posterior lobe ; the elytraeach with the following white markings—a transverse curved fascia 
below the base, extending forward along the suture, and sometimes connected with a short streak on the 
base of the sixth interstice, an oblique or triangular patch on the disc towards the apex, and a small 
streak at the tip,—the rest of their vestiture fuscous ; the under surface with white and ochreous, hair-like. 
scales, the metathoracic episterna with pure white scales; the vestiture of the legs and rostrum sparse 
and white. Rostrum strongly arcuate, rather stout, moderately long, rugulose and faintly carinate, 
smoother at the tip, the antenne inserted beyond the middle. Prothorax transverse, rounded at the 
sides from near the base, constricted in front, densely, finely punctate. Elytra subtriangular, with rather 
prominent humeri; deeply punctate-striate, the interstices rugulose and somewhat convex. Beneath 
closely punctate; ventral segments 1 and 2 slightly depressed down the middle in the g. Legs long; 
femora acutely dentate. 
Length 2, breadth 1 millim. (¢ 9.)
