884 RHYNCHOPHORA. 
sides crenulate or feebly bidentate, the base strongly bisinuate; densely, rugulosely punctate, carinate 
down the anterior half, and with two or four tubercles on the disc and sometimes two smaller ones 
at the apex. Elytra strongly constricted below the shoulders and narrowing from a little beyond this 
to the apex, deeply sinuate at the base ; seriate-punctate, the interstices rugulose, 3, 5, 7, and 9 sharply 
costate, the ridge on 3 and 5 twice, and that on 7 once, broadly, abruptly interrupted. Mesosternum 
bituberculate in front. Ventral segments very sparsely, minutely punctate. Femora clavate, sharply 
bidentate, the outer tooth small. Tarsal claws with a short tooth. 
Length 4,4,-54, breadth 21,-31 millim. (¢ @.) 
Hab. Mexico (ex coll. Flohr); Guatemaua, Cerro Zunil, San Gerénimo (Champion) ; 
Panama, Volcan de Chiriqui (Champion). 
Eleven specimens, varying greatly in size. ‘The nodose, anteriorly carinate prothorax, 
the large, dense, pallid fascia on the elytra beyond the middle, the conspicuously 
annulate rostrum and femora, the latter acutely bidentate, and the close ochreous 
vestiture of the mesothoracic epimera separate C. discifer from most of its allies. 
The two large elevations on the elytra are placed further forward than in C. gibbi- 
rostris, and these are partly included in the large dorsal patch. 
77. Conotrachelus corallinus, sp.n. (Tab. XIX. figg. 21, 21a, 3.) 
Conotrachelus corallinus, Jekel, in litt. 
Oblong-ovate, shining, black, the elytra variegated to a greater or less extent with ferruginous, the antenne 
and the legs partly or entirely of that colour; the vestiture fine, close (except upon the bare space between 
the large tubercles of the elytra), longer on the prothorax, fulvous or brownish, mottled with white, the 
white scales tending to form an interrupted subapical fascia on the elytra and two rings on the femora, 
the anterior femora with a dense line of fulvous scales at the base above and the posterior pair with a 
large fulvous patch on the outer side towards the apex. Head closely punctate, depressed and foveate 
between the eyes; rostrum exceedingly stout, arched, gibbous at the base in the ¢, not longer than the 
head and prothorax, sulcate at the sides, tricarinate above, sparsely punctate and bare at the tip, 
the antenne inserted at about one-third from the apex, joint 2 of the funiculus slightly shorter than 1. 
Prothorax a little broader than long, narrowed in front, the sides more or less crenulate ; the surface 
uneven, rugulosely punctate, carinate to near the base, with three smooth prominent tubercles on each 
side of the disc and two at the apex. Elytra constricted below the shoulders, very coarsely seriate- 
punctate, the interstices 3, 5, 7, and 9 sharply costate, the ridge on 3 and 5 twice, and that on 7 once, 
broadly, abruptly interrupted, the median elevation on 3 swollen, somewhat curved posteriorly, and 
very prominent. Mesosternum flattened between the coxes, bituberculate in front. Ventral segments 
almost smooth, 5 deeply foveate on each side in the ¢. Femora clavate, bidentate, the outer tooth on 
the anterior pair sometimes very little smaller than the inner. Tarsal claws with a short tooth. 
Length 44-63, breadth 23-34 millim. (¢ 9.) 
fab. Mexico (Mus. Brit.), Ventanas in Durango (Forrer), Tepetlapa, Teapa 
(H. H. Sinith), Cuernavaca, Tapachula (Hége), Vera Cruz (Sallé). 
Nine specimens, varying in size and colour. More shining than C. nodulosus, the 
pubescence more or less variegate, the elytra bare between the two large, swollen, 
dorsal prominences, the teeth on the anterior femora almost equal in size, the male 
with the rostrum gibbous at the base and the posterior tibiee not excavate at the apex. 
The tubercles are sometimes in great part red. The conspicuously tuberculate 
prothorax separates C. corallinus from the North-American C. nenuphar (Herbst).
