404 RHYNCHOPHORA. 
rugosely punctate, and without condensed spots on the disc; the elytra more feebly costate, usually more 
or less mottled with whitish, especially behind a transverse, almost bare, common, post-median fascia ; 
the ventral segments coarsely, closely punctate, 5 truncate at the apex in the ¢, the pygidium not 
visible in this sex; the mesosternum flattened between the cox, binodose and protuberant in front; 
the femora sharply unidentate ; the posterior tibie of the 3 similar to those of the 9. 
Var, The elytral interstices 1 and 2 also costate. 
Length 33-5, breadth 1,%-23 millim. (5 2.) 
Hab. Norru America, Southern States 2, Florida }\—Mexico, Cordova, Cerro de 
Plumas, Jalapa (Hoge), Yolos (Sailé); Guatemaua, Capetillo, San Gerénimo 
(Champion); Panama, Volcan de Chiriqui (Champion). 
Central-American examples differ from others from the United States sent me by 
Mr. Wickham in having the ventral segments a little less closely punctured. Both 
forms have been found at Yolos. A similar variety is also noticed by Leconte. 
114. Conotrachelus suturalis, sp.n. (Tab. XX. figg. 16, 16a, ¢.) 
Oblong-ovate, shining, piveous, more or less mottled with ferruginous, the suture of the elytra blackish and 
the coste rufescent; the vestiture rather coarse, close, ochreous or fulvous, intermixed with white, 
becoming sparser on a large subtriangular space on the disc of the prothorax, the elytra with a broad, 
transverse, subapical white fascia and the clothing thence to the apex in great part fulvous, the squamosity 
of the under surface sparse. Head densely punctate; rostrum moderately stout, curved, a little longer 
than the head and prothorax, rugulosely punctate and 5-carinate, smoother at the tip, the antenn» 
inserted at about one-fourth from the apex, joints 1 and 2 of the funiculus equal in length. Prothorax 
transverse, rounded at the sides anteriorly, parallel behind, narrowed and constricted in front, moderately 
bisinuate at the base; densely, rugulosely punctate, and sharply carinate from the apex to near the base. 
Elytra oblong, gradually narrowing from a little below the base, the humeri rounded ; coarsely seriate- 
punctate, the interstices closely rugulose and faintly granulate, 3, 5, 7, and 9 costate throughout. Meso- 
sternum flattened between the cox, rather narrow. Ventral segments very sparsely, finely punctate, 
5 foveate in the middle. Legs stout; femora strongly clavate, each with a triangular tooth and a minute 
prominence a little exterior to it; tarsal claws with the inner tooth almost as long as the claw itself. 
Length 54-6, breadth 3 millim. (<¢.) 
Hab. Guatema.a, Cerro Zunil 4000 feet (Champion). 
Two males. Differs from most of its allies with uninterruptedly costate alternate 
elytral interstices in having a broad white subapical fascia, also in the very sparsely 
punctate abdomen and the long tooth to the tarsal claws. C. suturalis superficially 
resembles C. inequidens, but the latter has quadridentate posterior femora, a slender 
rostrum, a shorter, non-carinate prothorax, &c. 
115. Conotrachelus albopictus, sp.n. (Tab. XX. figg. 17, 17 a.) 
Broad ovate, feebly shining, nigro-piceous; the vestiture rather sparse, ferruginous, here and there very 
slightly intermixed with white, the elytra with a transverse mark on each shoulder, a minute spot at the 
base of the third interstice, and an interrupted transverse mark on each side of the suture beyond the 
middle, densely clothed with narrow white scales, the femora each with a narrow, incomplete, white 
ring. Head closely punctate, transversely depressed in front; rostrum very stout, strongly arcuate, 
somewhat gibbous at the base above, a little longer than the head and prothorax, rugulose and striate, 
carinate down the middle, thickly punctate at the tip, the antenne inserted towards the apex, joint 2 of 
the funiculus shorter than 1. Prothorax transverse, rounded at the sides anteriorly, constricted and
