CYRIONYX. 203 
submarginal one continued down the disc of each elytron to the apex, and sometimes divided into three 
spots or streaks, the rest of the vestiture of the upper surface blackish-brown, that of the under surface 
wholly white, the legs and rostrum with narrow whitish scales. Rostrum arcuate, moderately stout, 
rugulose and finely carinate, smoother at the tip, the antenne inserted beyond the middle. Prothorax 
transverse, rounded at the sides from near the base, feebly constricted in front ; densely, finely punctate. 
Elytra subtriangular, finely punctate-striate, the interstices flat and rugulosely punctate. Beneath closely 
punctate ; first ventral segment excavate down the middle in the ¢. Legs long; femora acutely dentate ; 
anterior and intermediate tibize somewhat curved, 
Length 21-21, breadth 115 milim. (¢ 2.) 
Hab. Paxama, Bugaba (Champion). 
Three specimens. In this insect the prothorax and elytra have a continuous (or 
interrupted) submarginal white stripe, as in various Ambates ; the vestiture of the under 
surface, too, is close and white. The finely striate elytra, with flat interstices, separate 
C. ambatoides from C. clathratus and its allies. 
31. Cyrionyx oblongoguttatus, sp.n. (Tab. XI. fig. 30.) 
Subovate, obscure ferruginous; the prothorax and elytra mottled with minute ochreous and blackish scales, 
the ochreous scales on the prothorax condensed into a curved, interrupted band on each side of the disc 
and a small spot at the middle of the subapical constriction, the elytra each with a dense, oblong patch 
of coarser, whitish scales on the disc towards the apex (extending from the third to the fifth stria); the 
sparse vestiture of the head and under surface whitish, that of the legs ochreous. Rostrum arcuate, not 
longer than the head and prothorax, moderately stout, rugulose at the sides, smooth along the centre, the 
antenn inserted beyond the middle. Prothorax transverse, rather convex, rounded at the sides, strongly 
constricted in front; densely, finely punctate. Elytra subtriangular, the humeri somewhat prominent ; 
finely punctate-striate, the interstices rugulose and feebly convex. Ventral segments sparsely punctate, 
1 depressed down the middle. Legs elongate; femora acutely dentate. 
Length 24, breadth 15 millim. (d.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
One specimen. More elongate than C. biplagiatus, Faust, from Venezuela, the 
rostrum smoother, the anterior coxe contiguous, the legs much longer, &c. The dense 
oblong white patch on each elytron is similarly placed in the two species. 
32. Cyrionyx squamans, sp. n. 
Subrhomboidal, shining, piceous, the rostrum, antenne, femora, and tibie partly or entirely ferruginous ; the 
vestiture dense and squamiform: the prothorax and elytra mottled with brown and ochraceous (or 
whitish), the pallid scales on the prothorax condensed into a median and a submarginal vitta, and those 
on the elytra sometimes clustered into an oblong spot on the fourth interstice before the middle and a 
large patch or oblong streak on the disc towards the apex; the scales on the under surface and legs 
wholly whitish or ochraceous. Rostrum stout, arcuate, longer than the head and prothorax, sparsely 
the base, the antenns inserted at the middle. Prothorax 
Elytra broad at the base, 
Beneath closely punctate. 
punctate, rugulose and faintly carinate at 
transverse, conical, feebly constricted in front ; densely, finely punctate. 
subtriangular ; finely punctate-striate, the interstices broad, flat, and rugulose. 
Prosternal sulcus shallow. Legs rather stout ; femora sharply dentate. 
Length 24-22, breadth 13-13 millim. ( 2.) 
Hab. Panama, Bugaba (Champion).
