76 RHYNCHOPHORA. 
difference in the sculpture of the prothorax alone being sufficient to distinguish them. 
The elytral markings are similar. C. maculosus has the general facies of C. histricus. 
14. Copturus tricolor, sp. n. (Tab. V. figg. 14, 142@.) 
Subelliptic, flattened above, black, the antenne obscure ferruginous, the vestiture dense and fine: the eyes 
encircled by an ochreous line; the prothorax with four sharply-defined black vitte, extending from the 
base to the carmine-red band in front, the two vitte on each side usually connected anteriorly, the outer 
one coalescent with the transverse black fascia running down the flanks, the intervening spaces ochreous ; 
the elytra brownish or purplish-brown variegated with cinereous, the cinereous scales condensed into a 
curved patch on each side of the suture at the base, two or three spots at the sides, and a stripe down 
each alternate interstice; the under surface white or yellowish-white, variegated with black along the 
sides, the ventral segment 2 with a broad, posteriorly trilobate black band in front, the median branch 
running downwards to the apex of 5. Eyes very narrowly separated. Rostrum rugulosely punctate and 
carinate at the base, the lateral sulci (scrobes) extending forwards to near the apex. Joint 2 of the 
funiculus nearly as long as 3 and 4 united. Prothorax transverse, gradually narrowing from the base, 
constricted in front; densely, finely punctate. Elytra narrowing from a little below the base, obliquely 
truncated at the apex; fincly striate, the strie feebly punctate, the interstices flat. Meso- and meta- 
sternum slightly depressed between the middle coxe. Femora unidentate, the posterior pair strongly 
compressed, not reaching beyond the apex of the abdomen, and with the inner apical lobe spiniform, the 
intermediate and posterior pairs carinate externally. 
Length 6-7, breadth 3-34 millim, 
Hab. Mexico, Cordova (Sa/lé); GuatemMaLa, Senahu in Vera Paz (Champion) ; 
Nicaragua (Sallé), Chontales (Belt). 
Five specimens. Larger than C. neohispanicus ; the prothorax with the four sharply- 
defined black vittee on the posterior lobe separated by ochreous interspaces ; the elytra 
with a common, interrupted, »-shaped cinereous patch at the base, finely striate, the 
interstices flat; the metasternum without definite impression between the middle coxe. 
15. Copturus montezuma, sp.n. (Tab. V. fig. 15.) 
Copturus (Eucopturus) montezuma, Heller, in litt. 
Subelliptic, robust, black, the antenne ferruginous, the vestiture close and fine: the head with an ochreous 
line around the eyes which becomes red above ; the prothorax black, with three narrow ochreous vittee 
extending forwards to the carmine-red band in front; the elytra black or blackish-brown, with a small 
subquadrate patch on the suture at the base, an oblique streak below the shoulder, and various interrupted 
lines on the disc, ochreous or fulvous, the rest of the suture and two transverse streaks at the sides (one 
at*about the middle, the other midway between this and the apex) white; the under surface white, 
except upon the large, almost bare spaces extending across the flanks, metasternum, and abdomen, the 
second ventral segment with a median vitta, and the fifth with a transverse space at the apex, also black. 
Eyes narrowly separated. Joint 2 of the funiculus very elongate, about as long as 3-6 united. Prothorax 
short, gradually narrowing from near the base, feebly constricted in front ; densely, finely punctate and 
obsoletely carinate. Elytra somewhat cordate, depressed along the suture; rather coarsely punctate- 
striate, the interstices convex. Meso- and metasternum flattened between the coxe. Legs moderately 
long ; femora unidentate, the posterior pair strongly compressed, reaching a little beyond the apex of the 
abdomen, the intermediate and posterior pairs carinate externally, the inner apical lobe of the latter 
acute. 
Length 6-63, breadth 3;4,-33 millim.
