408 RHYNCHOPHORA. 
121. Conotrachelus fulvolineatus, sp. n. 
Oblong-ovate, narrow, shining, black, the tibia and tarsi mottled with ferruginous, the antenne of the same 
colour ; the vestiture coarse, fulvous and white intermixed, dense, except upon the scattered bare spaces 
on the prothorax and elytra, the fulvous squamosity on the latter condensed into a stripe down each of 
the alternate interstices and some irregular markings at the apex, the white scales clustered into spots on 
the disc, at the base of the third interstice, and on the shoulder, the rostrum densely squamose to the tip, 
the femora biannulate, the under surface (the abdomen excepted) thickly clothed with elongate white 
scales. Head convex, the eyes separated by a little less than the width of the rostrum; rostrum very 
stout, as long as the prothorax, feebly curved, rugulose to the tip, the antenne inserted near the apex, 
joints 4-7 of the funiculus transverse, 2 much shorter than 1. Prothorax about as long as broad, 
narrowed and feebly constricted in front, moderately bisinuate at the base, the sides parallel behind ; 
densely, rugulosely punctate. Elytra about one-half wider than the prothorax, narrowing from a little 
below the base, the humeri obliquely truncated and rather prominent; coarsely seriate-punctate, the 
interstices rugulose, 3, 5, 7, and 9 moderately costate, the ridge on 3 slightly depressed below the base. 
Mesosternum flattened between the coxe, declivous in front. Ventral segments sparsely, finely punctate. 
Femora clavate, the intermediate and posterior pairs each with an acute triangular tooth and a minute 
prominence placed at some distance exterior to it, the anterior pair with two minute prominences only. 
Anterior tibie deeply sinuate within; posterior tibie strongly and abruptly unguiculate, and also ciliate, 
at the apex, the claw curved at the tip. Tarsal claws with a moderately long tooth. 
Length 32, breadth 12 millim. (¢.) 
fab. Panama, Volcan de Chiriqui 5000 feet (Champion). 
One example. <A small species somewhat resembling C. continuus, but with the 
vestiture coarser, denser beneath, and that on the elytra alternately fulvo-lineate and 
albo-tessellate, the rostrum densely squamose to the tip, the prothorax nearly as long 
as broad, the elytra rather narrew and with more prominent humeri; the posterior 
‘tibie (¢ ) with a strong curved claw at the apex. 
122. Conotrachelus silvicola, sp. n. 
Subovate, rather narrow, robust, feebly shining, black, the elytra piceous or rufo-piceous, the antenne obscure 
ferruginous ; thickly clothed with small, oval, ochreous scales, which sometimes become paler at each hind 
angle of the prothorax and on the front of the humeri, the prothorax with a large almost bare space on 
the posterior half of the disc, the vestiture of the under surface very sparse and whitish, the femora 
obsoletely annulate, the upper surface also clothed with short, semierect, scattered, whitish sete, which 
on the elytra are subseriately arranged down each of the alternate interstices. Head densely punctate ; 
rostrum moderately stout, curved, a little longer than the head and prothorax, in the g rugulosely punctate 
and tricarinate, with the apex thickly punctate, in the 2 much smoother, the antenne inserted towards 
the tip, joint 2 of the funiculus shorter than 1. Prothorax convex, transverse, rounded at the sides 
anteriorly, narrowed and constricted in front, moderately bisinuate at the base; densely, finely punctate, 
and more or less distinctly carinate at the middle. LElytra about one-half wider than the prothorax, 
narrowing from a little below the base, the humeri rounded ; punctate-striate, the interstices densely 
rugulose, 3, 5, 7, and 9 narrowly, feebly costate, the ridge on 8 becoming obsolete or indistinct towards 
the base. Mesosternum simply flattened between the coxw. Ventral segments sparsely, rather coarsely 
punctate, 5 broadly and shallowly depressed in the middle behind in the g. Legs stout; femora clavate, 
unidentate ; intermediate and posterior tibie slightly hollowed at the apex within in the ¢; tarsal claws 
with a short, stout tooth. 
Length 33-4, breadth 1,%-2 millim. (¢ 9.) 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
Five specimens. Not unlike C. rugulosus, but narrower, the prothorax more rounded
