CONOTRACHELUS. 379 
68. Conotrachelus sellatus, sp. n. 
Subovate, dull, black, the elytra and legs mottled with reddish, the antenne of the same colour ; the vestiture 
close, whitish, slightly intermixed with ochreous, condensed into faint, curved, confluent lines on the 
disc and sides of the prothorax, the elytra with an ochreous patch on each shoulder and a broad, curved, 
common, whitish fascia beyond the middle, the femora obsoletely biannulate with white, the anterior 
pair with a narrow fulvous line at the base above. Head closely punctate, depressed between the eyes ; 
rostrum exceedingly stout, curved, as long as the prothorax, laterally sulcate, rugulosely punctate and 
feebly carinate at the base, very sparsely punctate, bare, and shining from the middle onwards, the antenne 
inserted at about one-third from the apex, joint 2 of the funiculus much shorter than 1. Prothorax 
convex, rounded at the sides anteriorly, narrowed and constricted in front, strongly bisinuate at the base ; 
the entire surface densely, rugulosely punctate. Elytra flattened on the disc below the base, constricted 
beneath the humeri, the latter rounded and not prominent; seriate-punctate, the interstices rugulose, 
3, 5,7, and 9 moderately costate, the ridge on 3 twice, and that on 5 and 7 once, broadly interrupted. 
Mesosternum flattened between the coxe, slightly hollowed in front. Ventral segments shining, sparsely, 
finely punctate. Femora strongly clavate, each with a sharp tooth and a minute prominence exterior to 
it. Tarsal claws with a short tooth. 
Length 53, breadth 27 millim. ( 9.) 
Hab. Mexico, Cuernavaca (f6ge). 
One specimen. Very like C. curvilineatus, but with the rostrum smoother and 
stouter (in the @), the prothorax less coarsely punctate, the interrupted elytral coste 
less raised, the humeri rounded and less prominent, the broad post-median fascia 
whitish and less transverse. This insect approaches the North-American C. albicinctus, 
Lec., but it has the ventral segments much smoother, and the outer femoral tooth 
reduced to a minute prominence. The more convex prothorax, &c., separate it from 
C. flavangulus and others. 
69. Conotrachelus curvilineatus, sp.n. (Tab. XIX. fig. 16, 16a, ¢.) 
Subovate, rather dull, black, the elytra sometimes reddish, or with at least the large dorsal tubercles of that 
colour, the antennew, and the tibiz and tarsi in part, ferruginous ; the vestiture close and rather coarse, 
sparse on the disc of the prothorax behind, fulvous or ochreous, intermixed with white, the prothorax 
with two white (or partly white) lines on each side—the inner one curving inwards before the middle, 
the outer one curving outwards anteriorly and connected with an irregular white patch on the disc in 
front, the elytra with a dense ochreous patch at the shoulders and a broad, common, transverse, similarly- 
coloured subapical fascia, the latter marked with white posteriorly, the femora biannulate with ochreous 
or white, the anterior pair with a short fulvous streak at the base above. Head densely punctate, 
depressed between the eyes ; rostrum exceedingly stout, curved, not longer than the head and prothorax, 
squamose and rugulosely punctate, sulcate laterally and feebly tricarinate, somewhat gibbous at the base, 
the apex bare and sparsely punctate, the antenne inserted at about one-third from the apex, joint 2 of 
the funiculus much shorter than 1. Prothorax convex, a little broader than long, rounded at the sides 
anteriorly, narrowed and constricted in front, bisinuate at the base; densely, rugulosely punctate, 
obsoletely carinate before the middle. Elytra depressed towards the base, constricted beneath the rather 
prominent humeri, and narrowing from a little below this to the apex; seriate-punctate, the interstices 
rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 3 twice, and that on 5 once, broadly, abruptly inter- 
rupted. Mesosternum flattened between the coxa, slightly hollowed in front. Ventral segments shining, 
very finely, sparsely punctate. Femora strongly clavate, each with a sharp tooth and a very small 
prominence exterior to it. Intermediate tibia feebly excavate at the apex within in the d. Tarsal 
claws with a short tooth. 
Length 43-6, breadth 23-3} millim. (¢ 2.)
