300 RHYNCHOPHORA. 
narrowing forwards and slightly constricted in front, the sides somewhat rounded, the surface (except 
upon the vitte) closely granulate. Scutellum transversely cordate. Elytra at the sides forming an almost 
continuous outline with the prothorax, elongato-cordate, transversely depressed at the base; closely, 
irregularly granulate and also indistinctly seriate-punctate. Beneath finely punctate and feebly granulate, 
the first ventral segment depressed along the middle. Mesosternum not raised between the coxe. Legs 
rather elongate ; femora each with a narrow tooth, that on the anterior pair long. 
Length 14, breadth 54 millim. (¢.) . 
Hab. Guatemaua, El Tumbador, Pacific slope, 2500 feet (Champion). 
One specimen. Narrower than C. cinctus (Drury), the elytra at the sides forming 
an almost continuous outline with the prothorax, the whitish vitta more distant from 
the margin, sharply defined, and placed in a shallow groove (as in the South-American 
C. albicinctus, Germ.), the granulation of the elytra more irregular, &c. 
20. Cholus inzequalis, sp.n. (Tab. XV. figg. 25, 25a, 3.) 
Oblong, subelliptic, flattened above, piceous or black, dull, thickly clothed above and beneath with minute 
brownish scales, the prothorax with a faint line of paler scales on each side of the disc, which is continued 
on to the head and the base of the rostrum. Head closely, finely punctate, longitudinally rugose between 
the eyes; rostrum stout, much longer than the prothorax, curved, widened at the tip, sulcate on each 
side at the base above, in the ¢ rugulosely punctate, in the 2 almost smooth from the sulci to 
the apex. Prothorax transverse, rounded at the sides posteriorly, rapidly narrowing from a little before 
the base to the apex, slightly constricted in front; finely and somewhat closely granulate, and with 
indications of a bare median line, the interspaces alutaceous. Scutellum transverse, rather large. Elytra 
a little wider than the prothorax, elongato-cordate, uneven, the third interstice sometimes costate in its 
median third, or the disc transversely wrinkled or irregularly depressed ; seriate-punctate and finely 
granulate, the interspaces alutaceous. Beneath dull, alutaceous. Mesosternum flattened between the 
coxe. First ventral segment unimpressed in the male. Femora each with a narrow tooth. 
Length 13-18, breadth 53-71 millim. (¢ 9.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Six specimens. More elongate than C. alutaceus, the elytra relatively narrower at 
the base, uneven, and with the vestiture closer and uniform throughout, the scutellum 
transverse, the mesonotum not protuberant. C. delumbis, Pasc., from Ecuador, is also 
not unlike the present species, but it is broader and has the elytra still more uneven, 
and the upper surface more coarsely granulate. 
21. Cholus morio, sp. n. (Lab. XV. figg. 26, 26 a.) 
Cholus morio, Sturm, in litt. 
Oval, black, shining, the antenne obscure ferruginous; very sparsely clothed with minute, narrow, whitish 
scales, the pro-, meso-, and metasternum, and the sides of the first ventral segment, with some coarse, 
oval, yellowish scales. Head closely punctate, foveate between the eyes ; rostrum very much longer than 
the prothorax, curved, rather slender, sparsely punctate at the base, for the rest smooth, the antenne 
inserted at the middle. Prothorax broader than long, rounded at the sides, much narrowed and strongly 
constricted in front, punctate and irregularly, confluently granulate, the anterior margin sinuate. 
Scutellum oblong. LElytra at the sides forming an almost continuous outline with the prothorax, sub- 
cordate, somewhat flattened on the disc, the subapical callosities rather prominent; coarsely seriate- 
punctate, the interstices and the spaces between the seriate punctures granulate or transversely wrinkled. 
Ventral segments very sparsely punctate, 1 and 2 broadly depressed down the middle. Mesosternum
