CONOTRACHELUS. 349 
unidentate. Posterior tibie dilated at the outer apical angle. Tarsal claws with the tooth about as long 
as the claw itself. 
Length 43-5, breadth 22-21 millim. (¢ 9.) 
Hab. Panama, Volcan de Chiriqui 2500-4000 feet (Champion). 
One pair. ‘This species somewhat resembles C. dentiferus, but the vestiture is 
sparser and differently coloured above (though very dense on the flanks of the 
prothorax), the elytra have a large reddish humeral patch, the rostrum of the female is 
elongate and also very much smoother than that of the male, with the antenne inserted 
at the middle, the femora acutely unidentate, the posterior tibie dilated at the apex, &c. 
12. Conotrachelus oculatus, sp. n. (Tab. XVIII. fig. 12, head and ros- 
trum, 2.) - 
Subovate, shining, ferruginous, the elytra and femora mottled with piceous, the prothorax black, with the 
apex ferruginous, the under surface piceous ; the vestiture rather coarse, pale ochreous, condensed along 
the basal margin of the prothorax and forming two small transverse marks on its disc, and clustered into 
numerous scattered spots on the elytra, becoming much denser on the depressed basal portion of the 
latter, the femora conspicuously annulate with whitish at the apex and with a narrow annulus nearer 
the middle, the anterior pair with an ochreous streak at the base above. Head densely punctate, tho 
eyes very large and rather narrowly separated; rostrum very stout, abruptly arcuate, a little longer than 
the head and prothorax, almost smooth, unicarinate and opaque at the base, the antenne inserted at the 
middle, joint 2 of the funiculus shorter than 1. Prothorax strongly transverse, narrowed and constricted 
in front, and deeply bisinuate at the base, the ocular lobes feebly developed; densely, rugulosely punctate, 
and finely carinate to near the base. Elytra subtriangular, rounded at the sides posteriorly, feebly 
sinuate at the base, broadly flattened anteriorly, the humeri obliquely truncate; punctate-striate, the 
interstices rugulose, 3, 5, 7, and 9 narrowly costate, the ridge on 3 twice, and that on 7 once, interrupted. 
Mesosternum flattened between the coxe, slightly hollowed in the middle anteriorly. Ventral segments 
very sparsely, finely punctate. Femora clavate, each with a triangular tooth and a minute prominence 
placed at some distance exterior to it. Tarsal claws with a very short tooth. 
Length 5, breadth 23 millim. (9.) 
Hab. Mexico, Colima city ({ége). 
One female. ‘The very large, rather narrowly separated eyes, the almost smooth, 
stout rostrum, the feebly developed ocular lobes of the prothorax, the anteriorly 
flattened, subtriangular elytra, with the vestiture becoming much denser towards the 
base, and the conspicuously annulate femora, sufficiently characterize this species.. 
C. varicolor is an allied form. 
13. Conotrachelus triannulatus, sp. n. 
Subovate, rather dull, black, the elytra and legs mottled with obscure ferruginous, the antenne and the base 
and apex of the rostrum of the same colour; the vestiture close, rather coarse, fulvous, slightly inter- 
mixed with white, somewhat fasciculate on the elytra, the latter with a transverse, dense, ochreous and 
whitish patch on each side at the base and some small fulyous spots at the apex, the head with an 
interrupted white ring, and the prothorax with an interrupted curved line on each side of the disc and. a 
minute spot at each hind angle also white, the femora triannulate with ochreous, the anterior pair with 
a short fulvous line at the base above. Head densely punctate, the eyes separated by a little less than 
the width of the rostrum; rostrum cylindrical, slender, feebly curved, longer than the head and 
prothorax, shallowly striate and squamose at the base and for the rest bare and almost smooth, the
