CONOTRACHELUS. 415 
distance exterior to it; posterior tibise hollowed and ciliate in their apical fourth within, and with a 
long terminal claw, in the ¢; tarsal claws with a short tooth. 
Length 43-54, breadth 21-3 millim. (¢ Q.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Numerous examples. In this insect the rostrum is short and stout, and widened 
towards the middle, the posterior tibie are hollowed and ciliate at the apex within 
in the ¢, the mesosternum is vertical and feebly emarginate in front, the femora are 
biannulate, and the body is ferruginous, marked with black above. 
134. Conotrachelus dilatirostris, sp. n. (Tab. XX. figg. 29, 29a, 9; 30, 
rostrum from in front, ¢ .) 
Subovate, rather dull, nigro-piceous or black, with rufo-piceous or ferruginous markings, which on the elytra 
are mainly vonfined to the sides and apex; the vestiture very sparse, short, ochreous, becoming much 
closer on the reddish portions of the elytra, condensed into a faint curved line on each side of the disc of 
the prothorax and a minute spot at each hind angle, and sometimes into a small spot within the humeri 
in front, the elytra also with a short, conspicuous, narrow patch of white scales on the third interstice at 
the base; the femora faintly biannulate with whitish, the anterior pair with a line of fulvous scales 
along their basal half above. Head rugosely punctate, feebly carinate, foveate, and transversely grooved 
between the eyes ; rostrum very stout, widened in its median third, arcuate, not longer than the head 
and prothorax, 5-carinate, the apical portion thickly punctate in the g and sparsely so in the 9, the 
antenne inserted at one-fourth from the tip, joint 2 of the funiculus slightly shorter than 1. Prothorax 
a little broader than long, abruptly narrowed and constricted in front, the sides thence to the base crenu- 
‘late and almost straight, the base deeply bisinuate ; coarsely, rugosely punctate, feebly carinate anteriorly. 
Elytra obliquely constricted behind the humeri, and narrowing from a little beyond this to the apex ; 
coarsely seriate-punctate, the interstices rugulose, 3, 5, 7, and 9 costate, the ridge on 3 and 5 twice, and 
that on 7 once, abruptly interrupted. Mesosternum flattened between the coxa, obsoletely bituberculate 
in front. Ventral segments shining, very sparsely, minutely punctate, 1 depressed down the middle in 
the ¢. Legs stout; femora clavate, each with a sharp triangular tooth, and a minute tooth about 
midway between it and the apex; tarsal claws with a short tooth. 
Length 32-5, breadth 2-23 millim. (d @.) 
Hab. Guatemata, Panzos and Teleman in Vera Paz (Champion); Costa Rica, San 
José (Biolley); Panama, Bugaba (Champion). 
Eleven specimens, eight of which are from Chiriqui. In this species the elytra have 
a common, broad space, extending from the base to beyond the middle, darker and 
more sparsely squamose than the rest of their surface, and a conspicuous narrow white 
patch at the base of the third interstice. It approaches C. semirufus, but is much 
smaller, the rostrum is more dilated at the middle, the femora have a distinct outer 
tooth, and the hind tibiz of the ¢ are not excavate at the tip. 
135. Conotrachelus sinuatocostatus, sp. n. 
Oblong-ovate, shining, nigro-piceous or black, the elytra and legs usually more or less mottled with rufo- 
piceous, the antenne and tarsi piceous or ferruginous ; the vestiture very sparse on the prothorax and 
under surface, closer elsewhere, ochreous, slightly intermixed with whitish, subfasciculate on the elytra 
and also condensed on the latter into a small spot at the base of the third interstice and another on the 
shoulder, the prothorax also with two small ochreous spots on the disc anteriorly, the femora with a
