interstice are more prominent. ‘There are traces of a faint oblique whitish streak 
extending forwards from the hind angles of the prothorax. 
40. Conotrachelus foveicollis, sp.n. (Tab. XIX. figg. 3, 8a, 3.) 
Oblong-ovate, rather broad, shining, black, the apical declivity of the elytra in part, the antenne, the base of 
the femora, the tibiw, and tarsi ferruginous; the vestiture short, rather close above (except upon the 
bare portions of the elytra), very sparse beneath, fulvous and white intermixed, becoming dense and 
almost entirely fulvous on the base of the rostrum and between the eyes, the white scales condensed on 
each side of the disc of the prothorax into a narrow, sharply defined, oblique line towards the apex and a 
faint line at the base, a line along the humeri in front, and an interrupted transverse fascia at about one- 
third from the apex of the elytra; the upper surface and legs also clothed with short, scattered, semierect 
sete, which on the elytra are rather long and conspicuous ; the femora biannulate with white. Head 
closely, finely punctate, transversely depressed and foveate between the eyes, subtuberculate on each side 
in front ; rostrum exceedingly stout, curved, about as long as the head and prothorax, densely, rugulosely 
punctate and feebly unicarinate, a little smoother at the tip, the antennee inserted at about one-fourth 
from the apex, joint 2 of the funiculus shorter than 1. Prothorax transverse, abruptly narrowed and 
constricted in front, subparallel behind, deeply bisinuate at the base ; very coarsely, irregularly punctate, 
the punctures well separated, the interspaces on the disc here and there smooth and nodose, and for the 
rest minutely punctate. Elytra a little more than twice the length of the prothorax, subparallel in their 
basal third, strongly sinuate in front ; coarsely seriate-punctate, the interstices rugulose, 3, 5, 7, and 9 
sharply costate, the ridge on 3 broadly twice, and that on 5 once, abruptly interrupted. Intermediate 
cox rather narrowly separated, the mesosternum flattened between them. Ventral segments very 
sparsely, finely punctate. Femora clavate, bidentate, the outer tooth small. Anterior tibie strongly 
sinuate. Tarsal claws with a long tooth. 
Length 5, breadth 23 millim. (¢.) 
Hab. Mexico, Teapa (HZ. H. Sinith), 
Var. 
Narrower and smaller; the prothorax with an angulated, narrow line of white scales on each side of the disc, 
the elytra (except on the apical declivity) with more numerous white scales, these being condensed into a 
well-defined fascia at one-third from the apex ; the head not tuberculate; the rostrum densely rugulose 
and squamose to near the tip in the ¢, smoother and more sparsely squamose in the 9; the prothorax 
very coarsely, irregularly, and somewhat sparsely foveolate on the middle of the disc ; the elytra some- 
times rufo-piceous, maculated with black, and less strongly costate. 
Length 47-43, breadth 2-2! millim. (¢ 2.)

41. Conotrachelus griseus, sp. n. 
Oblong-ovate, robust, rather broad, shining, black, the antenne and tarsi ferruginous ; the vestiture somewhat 
close, very fine, greyish, slightly intermixed with fulvous, that on the head and rostrum fulvous, the 
elytra with a rather large fulvous patch at the shoulder and a smaller one at the base of the third 
interstice, and also clothed with scattered pallid sete, the femora indistinctly biannulate with whitish. 
Head densely, rugosely punctured, feebly binodose in front, transversely depressed between the eyes; 
rostrum exceedingly stout, curved, about as long as the prothorax, squamose, densely rugulose, faintly 
carinate down the middle, the antenna inserted at about one-fourth from the tip, joints 1 and 2 of the
