78 RHYNCHOPHORA. 
18. Copturus quadricolor, sp. n. (Tab. V. fig. 18.) 
Very like C. cincticollis, but with the transverse carmine-red band on the front of the prothorax divided into 
two large spots, which are rounded posteriorly and rapidly narrowed beneath, the ochreous median vitta 
continued to the apex ; the elytra with a common triangular black patch at the base, extending outwards 
to the humeri and enclosing an oblong, subquadrate, ochreous scutellar patch, the vestiture thence to the 
apex brown intermixed with white, the white sutural stripe wanting. 
Length 4, breadth 2 millim. 
Hab. Nicaragua, Chontales (Janson, in coll. Fry). 
One specimen. This is the Nicaraguan form of C. cincticollis and it requires a 
distinctive name. 
19. Copturus ruficollis, sp.n. (Tab. V. fig. 19.) 
Very like C. cincticollis, but with the dark markings of the elytra not extending beyond the basal third, the 
vestiture thence to the apex uniformly fulvous, the seriate punctures each with a white hair-like scale ; 
the ventral segments clothed throughout with white scales, 
Length 3-34, breadth 13-1? millim. (?9.) 
Hab. Guatemata, Chacoj in Vera Paz (Champion); Panama, Bugaba (Champion). 
Two specimens. Perhaps an extreme form of C. cincticollist A worn specimen (2 ¢ ) 
from Chontales, Nicaragua (Janson), probably belongs to C. rujicollis, though it has 
the eyes somewhat widely separated above. The sexes of Hoplocopturus scintillans 
differ in a similar way. 
20. Copturus conturbatus. (Tab. V. fig. 20.) 
Copturus conturbatus, Heller, Abhandl. Mus. Dresd. no. 11, p. 31’. 
Copturus miniatus, Chevy. in litt.’. 
Hab. Mexico, Toxpam in Vera Cruz (Sallé!). 
This insect may be known by the colour and arrangement of the vestiture. The 
head has a line behind the eyes above, and the prothorax a large transverse patch on 
each side in front (the two patches connected along the anterior margin), fiery-red; the 
prothorax has three whitish or cinereous patches at the base (the outer one enclosing 
a small black spot); the elytra are mottled with cinereous (or whitish) and black, the 
cinereous scales condensed into large patches along the suture and on the apical half; 
the under surface and legs are uniformly whitish. 
21. Copturus torquatus. (Tab. V. fig. 21.) 
Copturus torquatus, Heller, Abhandl. Mus. Dresd. no. 11, p. 32°. 
Hab. Mexico}, Toxpam in Vera Cruz (Sallé). 
Apparently peculiar to Eastern Mexico. The vestiture in this species is coloured 
thus :—The head has a line behind the eyes above, and the prothorax the apical third, 
rufous, the latter with three patches at the base, and the elytra with a common
