610 RHYNCHOPHORA. 
4, Graphonotus biolleyi, sp.n. (Tab. XXX. figg. 4, 4a, ¢.) 
Oblong-ovate, black, the antenne and tarsi more or less ferruginous ; mottled above with small ochreous, 
cinereous, and blackish scales, the latter condensed into four small patches on the disc of the prothorax, 
the elytra each with a blackish spot on the third interstice below the base and a larger, oblique, 
subtriangular black mark near the suture at the middle of the disc, this being followed by a very large, 
common, pallid, scutiform, apical patch (enclosing some irregular dark markings), the ochreous scales on 
the prothorax condensed into a sinuous, curved vitta on each side of the disc, the elytra also with a few 
decumbent sete ; the vestiture of the under surface and legs pale, the posterior femora with an ochreous 
ring on the outer face. Head rugosely punctate and subcarinate, shallowly foveate between the large, 
narrowly separated eyes ; rostrum moderately stout, curved, rather short, rugosely punctate and feebly 
5-carinate at the base, the apical half finely punctate, the antenne inserted at the middle, joints 1 and 2 
of the funiculus equal in length, the club ovate. Prothorax transverse, rounded at the sides anteriorly, 
constricted and much narrowed in front; the disc sparsely, and the flanks closely, granulate, and also 
_with a sharp median carina. Elytra elongate, much wider than the prothorax, subparallel in their basal 
third ; seriate-punctate and sparsely granulate, the alternate interstices a little raised, the ridge on 3 
interrupted below the base. Ventral segments very sparsely punctate. Rostral canal not reaching the 
metasternum, the mesosternum horseshoe-shaped. Legs long and rather slender, the femora clavate and 
sharply unidentate. 
Length 8, breadth 33 millim. (d.) 
Hab. Costa Rica, San Isidro (Biolley). 
One specimen. Not unlike G. dituberculatus, but with the prothorax narrower and 
sparsely granulate, the elytra longer, and each with an oblique, subtriangular, velvety- 
black patch on the disc, the legs more slender, &c. 
5. Graphonotus maculicollis, sp.n. (Tab. XXX. figg. 5, 5a, 2.) 
Oblong-ovate, black, the antenne in part ferruginous, the rostrum rufo-piceous; mottled above with small 
fulvous, black, and cinereous scales, the black scales on the prothorax condensed into two sinuous, 
sharply-defined vittee on the disc, two small spots at the apex, and a small spot on each side before the 
middle, the elytra with a very large, ill-defined, fulvous apical patch, enclosing some irregular black and 
cinereous markings, and also set with scattered, very short, decumbent, setiform scales; the vestiture of 
the legs and under surface fulvous, slightly intermixed with cinereous. Head rugosely punctate, foveate 
between the very large, narrowly separated eyes; rostrum long, strongly curved, thickened, rugulose, 
and 5-carinate at the base, almost smooth from about the basal third, the antenne inserted behind the 
middle, joint 2 of the funiculus longer than 1, the club oblong-ovate, with oblique sutures. Prothorax 
transverse, constricted and much narrowed in front, the sides rounded anteriorly and parallel at the base ; 
sparsely granulate, without definite median carina. Elytra much wider than the prothorax, moderately 
long ; seriate-punctate and finely granulate, the interstices 3, 5, 7, 8, 9 raised, the ridge on 3 interrupted 
below the base and with the basal elevation prominent. Ventral segments sparsely punctate. Rostral 
canal about reaching the anterior edge of the metasternum. Legs long and rather slender ; the femora 
clavate and very sharply unidentate. 
Length 7-74, breadth 3-37 millim. ( 2.) 
Hab. Panama, Bugaba (Champion). 
‘Two specimens. Very similar to G. béolleyi, but with a. longer rostrum, a longer 
antennal club, a non-carinate prothorax, shorter elytra, the markings of the upper 
surface different, the mesosternum otherwise formed, &c. In the example figured 
the two black vittee on the prothorax are united anteriorly, forming an irregular 
M-shaped mark.
