CONOTRACHELUS. 383 
post-median, paler fascia on the elytra by the three sharply-defined ochreous lines on 
each side of the prothorax, the median one of these extending forwards and inwards 
to the apex; the dull upper surface ; the feebly tricarinate rostrum, &c. ‘The elytral 
costee are very broadly interrupted posteriorly. 
75. Conotrachelus nodulosus, sp. n. 
Oblong-ovate, dull, nigro-piceous or black, the antenne and the tarsi ferruginous ; the vestiture fine, close, 
brown, sometimes intermixed with grey, especially on the apical third of the elytra, the prothorax in one 
specimen with a faint, sinuous, whitish line on each side of the disc, the elytra also with very short, 
scattered, decumbent sete; the femora faintly biannulate with whitish, the anterior pair with a line of 
fulvous scales above. Head densely, rugulosely punctate, binodose in front, transversely depressed 
between the eyes; rostrum exceedingly stout, curved, a little longer than the prothorax, squamose, 
rugulose and tricarinate, the apex thickly punctate and bare in the ¢, and smoother in the Q, the 
antenn inserted at about one-third from the tip, joints 1 and 2 of the funiculus subequal in length. 
Prothorax slightly broader than long, abruptly narrowed in front, the margins thence to the base crenate 
and more or less tuberculate anteriorly, the base strongly bisinuate ; the surface uneven, closely, rugulosely 
punctate, finely carinate down the middle anteriorly, and here and there nodose, the three elevations on 
each side of the carina prominent. Elytra constricted below the humeri, deeply sinuate at the base; the 
interstices closely rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 3 and 5 twice, and that on 7 once, 
broadly, abruptly interrupted, 10 with a short ridge at the base. Mesosternum flattened between the 
coxe, hollowed or bituberculate in front. Ventral segments very sparsely, finely punctate. T'emora 
clavate, bidentate, the outer tooth small. Posterior tibie abruptly hollowed at the apex within in 
the ¢. Tarsal claws with a short tooth. 
Length 44-54, breadth 23-23 millim. (¢ 2.) 
Hab. Mexico, Jalapa (Hoge), Orizaba (H. H. Smith), Teapa (Loge, H. H. Smith), 
Juquila (Sailé); Guatemana, San Juan, Chiacam, San Joaquin, Tias Mercedes, Duenas, 
Capetillo (Champion). 
Numerous examples. The nodose, feebly carinate prothorax, with crenate or 
tuberculate sides, the dull upper surface, the brownish vestiture slightly intermixed 
with grey, the tricarinate, rugulose, squamose rostrum, the feebly setulose elytra, and 
the excavate apex of the posterior tibie in the male, chiefly distinguish C. nodulosus. 
It approaches C. trilineatus. The first two ventral segments are subconnate. 
76. Conotrachelus discifer, sp. n. (Tab. XIX. figg. 20, 20; 206, anterior 
leg.) 
Subovate, somewhat shining, black, mottled to a greater or less extent with ferruginous, the antenne and tarsi 
ferruginous; the vestiture rather close, ochreous or brownish, slightly intermixed with white, the 
prothorax with an angulated or interrupted white line on each side of the disc and sometimes a line at 
the sides, the elytra with a large, common, transverse, dense, sordid ochreous or whitish patch towards 
the apex, which becomes white on the third interstice behind, the rostrum and femora more or less 
distinctly bi- or triannulate with white, the anterior femora with a line of fulvous scales along their 
basal half above, the mesothoracic epimera thickly clothed with ochreous scales and the episterna with a 
white spot. Head closely punctate, foveate between the rather narrowly separated eyes ; rostrum curved, 
stout, as long as or a little longer than the head and prothorax, squamose, rugulose, and tricarinate, 
the apical portion bare, in the ¢ thickly, and in the 2 sparsely, punctate, the antenna inserted at about 
one-third (2) or one-fourth (3) from the tip, joint 2 of the funiculus shorter than 1. Prothorax 
slightly broader than long, abruptly narrowed and constricted in front and also narrowed behind, the
