CONOTRACHELUS. 371 
Prothorax transverse, constricted and abruptly narrowed in front, parallel behind, bisinuate at the base; 
the surface uneven, densely, rugulosely punctate, the disc usually carinate to near the base. LElytra 
subparallel anteriorly, transversely depressed below the base, the humeri rounded ; coarsely seriate- 
punctate, the interstices rugulose, 3,5, 7, and 9 costate, the ridge on 3 twice and that on 5 once or twice 
interrupted. Mesosternum flattened between the coxe. Ventral segments shining, 1-4 very sparsely, 
and 5 more closely, finely punctate, 5 flattened in the middle and foveate on each side. Femora each 
with a triangular tooth and a small prominence exterior to it. Tarsal claws with a short tooth. 
Length 43-5, breadth 24-25 millim. (d 92.) 
Hab. Mexico, Ventanas in Durango, Matamoros Izucar, Yautepec, Jalapa (Hoge), 
Toxpam (Sadlé), Teapa (H. H. Smith), Temax in N. Yucatan (Gaumer); GUATEMALA, 
Champerico, Coatepeque, Zapote (Champion); Costa Rica (Biolley); Panama, Bugaba 
(Champion). 
Sent in abundance from Yucatan. This insect exactly resembles C. seniculus, Lec. 
(a specimen of which has been sent me by Mr. Wickham), except that it has the 
ventral segments much more sparsely and finely punctate. The allied C. affinis, Boh., 
is said by Leconte to have broad, sinuous, curved lines on the prothorax, and two 
tubercles on the fifth ventral segment; and C. evegans, Boh., the ventral segments 
coarsely punctate. The broad elytral fascia is sometimes whitish. The close vestiture 
makes the upper surface appear opaque. 
54. Conotrachelus maculipes. 
Conotrachelus maculipes, Boh. in Schénh. Gen. Cure. vill. 2, p 450°. 
Subovate, rather dull, black or piceous, the antenne and tarsi more or less ferruginous ; the vestiture some- 
what coarse, sparse, fulvous or greyish, closer, subfasciculate, and slightly intermixed with white on the 
elytra, there being often two conspicuous white spots near the apex, the femora with a narrow whitish 
ring. Head densely, rugulosely punctate, slightly depressed between the eyes above ; rostrum stout, 
curved, about as long as the head and prothorax, rugulosely punctate and 5-carinate, in the Q much 
smoother in its outer half, the antennze inserted towards the apex, joints 1 and 2 of the funiculus subequal 
in length. Prothorax transverse, abruptly narrowed in front, the sides sinuous or subparallel thence to 
the base, subangulate anteriorly, the base feebly bisinuate; densely, rugulosely punctate, the disc 
obsoletely carinate at the middle and sometimes with one or two very small tubercles on each side 
of this. Elytra somewhat flattened on the disc anteriorly, constricted below the humeri, which are 
obliquely truncated in front; coarsely seriate-punctate, the interstices rugulose, 3, 5, 7, and 9 costate, 
the ridge on 3 and 5 twice, and that on 7 once, broadly, abruptly interrupted. Mesosternum flattened 
between the cox, protuberant and feebly emarginate in front. Ventral segments shining, sparsely 
punctate, 5 depressed in the middle at the apex in the ¢. Femora feebly clavate, unidentate. Inter- 
mediate and posterior tibie in the ¢ strongly, abruptly unguiculate at the apex. Tarsal claws with a 
moderately long tooth. 
Length 43-5, breadth 2-23 millim. (d 2.) 
Hab. Mexico, Toxpam in Vera Cruz (Sal/é), Villa Alta‘. 
Of this species, a fuller description of which is now required, we possess eight 
specimens, agreeing with the type (¢) communicated by Dr. Sjéstedt, the latter 
also being from the Sallé collection. It would be almost equally well placed near 
C. crenatus, the prothorax sometimes having distinct tubercles on the disc.
