308 RHYNCHOPHORA. 
37. Cholus aureus, sp. n. (Tab. XVI. figg. 16, 16 a—c, 3.) 
Oblong, subelliptic, somewhat flattened above, piceous, the antenne and legs more or less ferruginous; above 
and beneath densely clothed with coarse, flattened, oblong-oval, golden-yellow scales, the vestiture a little 
sparser down the middle of the pronotum, the vertex, scutellum, and the apex of the rostrum bare ; the 
femora also clothed with coarse yellow scales, the vestiture of the tibie and tarsi piliform. Head closely, 
finely punctate; rostrum stout, curved, longer than the prothorax, rugulose and obsoletely carinate, 
smoother at the tip; joint 1 of the funiculus nearly as long as 2-5 united. Prothorax transverse, rounded 
at the sides anteriorly, and narrowing from the middle forward, closely, minutely punctate, the interspaces 
on the dise here and there smooth and a little raised. Scutellum transverse. Elytra at the sides forming 
an almost continuous outline with the prothorax, elongato-cordate, the subapical callosities prominent ; 
closely, minutely, confusedly punctate. Mesosternum flattened between the coxe. First ventral segment 
slightly depressed down the middle. Legs rather short; femora each with an acute tooth ; tibice strongly 
mucronate at the inner apical angle and with a long hook at the outer angle. 
Length 84, breadth 33 millim. (<¢.) 
Hab. Panama, Bugaba (Champion).—Cotom1 (coll. Pascoe, in Mus. Brit.). 
Two specimens, the one from Bugaba in perfectly fresh condition. More elongate 
and less convex than C. cretaceus, the dense vestiture (fig. 16 ¢) almost golden in certain 
lights and uninterrupted, the scutellum transverse and bare, the legs reddish and not 
so stout, the tibie both mucronate and unguiculate at the apex. ‘The species in the 
Pascoe collection is labelled C. sguamosus, Boh., but this is a mistake, Boheman’s 
species having no visible scutellum ; the latter belongs to Lobaspis, Chevr.* 
38. Cholus estriatus, sp. n. (Tab. XVI. figg. 17,17 a, 2.) 
Narrow, subelliptic, nigro-eneous, shining, the antenne, rostrum, and legs in great part ferruginous; thickly 
clothed above and beneath with coarse, oval, brownish-white scales, which are condensed into a broad, 
oblique vitta on the outer part of the disc of each elytron; the vestiture of the legs piliform, the femora 
also with long scales. Head densely punctate; rostrum rather slender, curved, much longer than the 
prothorax, densely punctate and squamose at the base, for the rest bare and with widely scattered fine 
punctures, the antenne inserted about the middle. Prothorax broader than long, conical, slightly rounded 
at the sides behind, closely, finely punctate. Scutellum subcordate. Elytra slightly wider than the 
prothorax, elongato-cordate ; shallowly, longitudinally grooved (except upon the space occupied by the 
vitta), the interspaces becoming subcostate at the sides, the entire surface very finely, irregularly punctate, 
without rows of coarser impressions. First ventral segment broadly depressed down the middle in the ¢. 
Mesosternum flattened between the coxe. Legs elongate, rather slender; femora each with an acute 
tooth ; tibia mucronate at the inner apical angle, the outer angle unarmed. 
Length 73, breadth 3 millim. (¢ 9.) 
Hab. Panama, Volcan de Chiriqui 8000 feet (Champion). 
Two specimens, assumed to be sexes, but scarcely differing in the sculpture and 
vestiture of the rostrum. The conical prothorax, the more slender rostrum and legs, 
and the vittate elytra distinguish this species from both C. awreus and C. cretaceus. 
The tibie are unarmed at the outer apical angle.
