CONOTRACHELUS. 347 
Found in abundance in Chiriqui, a few specimens only having been received from the 
more northern localities. The median carina on the prothorax is often obsolete. ‘The 
subapical spots on the elytra are sometimes evanescent, the scales, too, varying in 
size. The type (2), from Brazil, has larger spots and some scattered coarse scales 
towards the tip, but otherwise agrees with the Central-American examples. 
8. Conotrachelus rectirostris, sp.n. (Tab. XVIII. fig. 8, 2.) 
Oblong-ovate, moderately shining, rufo-piceous; the vestiture rather long, somewhat close, ochreous and 
whitish intermixed, that on the prothorax condensed into a faint oblique line on each side of the disc and 
a longitudinal one on the flanks, the humeri sometimes with a small patch of ochreous scales in front ; 
the femora with a denser ring of ochreous or whitish scales beyond the middle, the anterior pair with a 
dense line of ochreous scales at the base above. Head closely punctate, foveate between the eyes; 
rostrum (¢ ) rather slender, feebly curved, depressed at the base above, nearly half the length of the 
body, 5-carinate, thickly punctured at the apex, (2) almost straight, slender, and simply striate, 
the apical half almost impunctate, the antennee inserted at about one-fourth from the apex in the 
3, and a little beyond the middle in the 9, joints 1 and 2 of the funiculus subequal in length. 
Prothorax broader than long, constricted and abruptly narrowed in front, subparallel behind, strongly 
bisinuate at the base; coarsely, confluently punctate, and often feebly carinate down the middle 
anteriorly. Elytra oblong-oval, strongly bisinuate at the base, the humeri rounded; coarsely seriate- 
punctate, the interstices rugulose, 3, 5, 7, and 9 costate, the ridge on 3 twice interrupted for a short 
distance, and that on 5 or 7 sometimes incomplete. Mesosternum flattened between the coxee, feebly 
bituberculate in front. Ventral segments shining, very sparsely, minutely punctate. Femora clavate, 
each with a broad acute triangular tooth. Tarsal claws with a long tooth. 
Length 62-74, breadth 33-32 millim. (¢ 2.) 
Hab. Guaremata, Mirandilla (Champion: 3 2); Panama, Bugaba (Champion: 3 @ ). 
Six specimens, four of which are from Guatemala. A small female from San 
Ger6énimo, Guatemala, with a smoother and shorter rostrum, may also belong here. 
Recognizable from C. guadrinotatus and its alles by the absence of the dense patches 
of scales on the elytra, the additional faint ochreous line on the flanks of the 
prothorax, and the less prominent humeri. ‘To judge from the description, C. recti- 
rostris approaches the South-American C. mamillatus, Boh. ; but it has a smoother 
rostrum and the ridge on the third elytral interstice is twice interrupted. There 
is a female of an unnamed species from Brazil in the British Museum that comes very 
near the present insect. 
9. Conotrachelus fulvescens, sp.n. (Tab. XVIII. figg. 9, head and rostrum, 
2; 9a,anterior femur.) 
Conotrachelus fulvescens, Jekel, in litt. 
Very like C. rectirostris, but with the rostrum curved in both sexes, strongly so in the Q, 5-carinate and 
pubescent in the 3, bare and almost smooth throughout in the Q, the broad tooth on the anterior 
femora slightly hollowed or notched externally. 
Length 53-6%, breadth 3-33 millim. (¢ Q.) 
Hab. Mexico (Mus. Brit.; Sallé), Jalapa (Hoge); Guatemata, Panima, Sabo, and 
San Gerdnimo in Vera Paz, Volcan de Atitlan, Las Mercedes, Capetillo (Champion) ; 
Costa Rica, San José (Bioll/ey); Panama, Volcan de Chiriqui (Champion).
