CONOTRACHELUS. 423 
147. Conotrachelus mexicanus, sp.n. (Tab. XXI. figg. 9,92, 2.) 
Subovate, rather convex, piceous, the legs mottled with ferruginous, the antenne and tarsi entirely of that 
colour ; above densely clothed with minute brown scales, the prothorax with a sharply defined, oblique, 
dense, fulvous or whitish line on each side of the disc, the two lines nearly meeting in front and 
continued posteriorly on to the humeri, the head with a similarly-coloured line down the middle and an 
oblique one on each side near the eyes, these uniting in front and continued as a single stripe along 
the upper part of the rostrum, the upper surface also with short, scattered, semierect, light and dark 
sete, those on the elytra seriately arranged down each interstice; the vestiture of the under surface 
and legs very sparse, whitish or ochreous, the femora annulate. Head densely punctate; rostrum 
exceedingly stout, about as long as the head and prothorax, abruptly incurved beyond the middle, 
rugulosely punctate, striate laterally, the apex rather sparsely punctured, the antenne inserted a little 
before the tip, joints 1 and 2 of the funiculus subequal in length, 4—7 transverse. Prothorax strongly 
transverse, narrowed and feebly constricted in front, bisinuate at the base; densely, finely punctate. 
Elytra rather narrow, less than twice the width of the prothorax, narrowing from a little below the base, 
the humeri rounded ; seriate-punctate, the interstices densely rugulose, 3, 5,7, and 9 costate, the ridge on 
3,5, and 7 much interrupted, that on 9 interrupted below the base only. Mesosternum flattened 
between the coxe, protuberant in the middle in front. Ventral segments shining, sparsely, coarsely 
punctate. Femora clavate, unidentate. Posterior tibie slightly hollowed at the apex within in the ¢. 
Tarsal claws with a short tooth. 
Length 33-31, breadth 1}-1,% millim. (¢d 2.)

Sent in numbers from Tabasco. The sharply-defined ochreous or whitish oblique 
line on each side of the disc of the prothorax, which is duplicated as it were on the 
head, the close brown vestiture of the rest of the upper surface, the very stout, short 
rostrum in both sexes, the rather narrow elytra, with much interrupted feebly raised 
dorsal coste, &c., distinguish this small species. 
148. Conotrachelus ramifer, sp. n. 
Subovate, moderately shining, nigro-piceous, the antenne, tarsi, and apices of the tibiew ferruginous ; somewhat 
sparsely clothed with minute, narrow, brown scales, the prothorax with a condensed sinuous line of 
white scales on each side of the disc, dividing into two posteriorly, and continued on to the humeri and 
the base of the third elytral interstice, the femora with a whitish ring, the upper surface also with 
scattered, clubbed, whitish sete. Head densely punctate, faintly foveate between the eyes; rostrum 
stout, curved, a little longer than the head and prothorax, rugulosely punctate and feebly unicarinate, 
thickly punctate at the tip, the antenne inserted towards the apex, joint 2 of the funiculus slightly 
shorter than 1. Prothorax transverse, abruptly narrowed and constricted in front, moderately bisinuate 
at the base ; densely, rugulosely punctate. Elytra narrowing from about the basal third, slightly constricted 
beneath the obliquely truncated humeri ; coarsely seriate-punctate, the punctures subquadrate, large, and 
deep, the interstices rugulose, 3, 5, 7, and 9 costate, the ridge on 3 twice, and that on 5 once or twice, 
broadly interrupted. Mesosternum conically protuberant in front. Ventral segments sparsely punctate. 
Femora clavate, unidentate. All the tibize slightly hollowed and sparsely ciliate at the apex within, and 
also strongly unguiculate, in the ¢. Tarsal claws with a short tooth, 
Length 31-34, breadth 12-2 millim. (d 2.)
