42 RHYNCHOPHORA. 
carinate and rugulose at the base. Prothorax transverse, gradually narrowing from the base, feebly 
constricted in front; densely, finely punctate. LElytra very little wider than the prothorax, somewhat 
oval, the apices conjointly rounded ; deeply punctate-striate, the interstices narrow, raised. Legs short. 
Length 23-3, breadth 14-14 millim. 
Hab. Muxico, Chilpancingo (J/. H. Smith), Cuernavaca (Zége), Guanajuato (Sallé, 
in Mus. Dresden). 
Three specimens, varying a little in the colour of the scales. Smaller and less 
elongate than C. elongatus, the scales smaller, the prothorax much shorter and more 
finely punctate, the intra-ocular space narrower and almost equal in width, the elytra 
without well-defined black patch on the disc. 
ZY GOPSELLA, gen. nov. 
Antenne: inserted near the middle of the rostrum, joints 1 and 2 of the funiculus equal in length, 3-7 short, 
6 and 7 transverse, the club narrow, acuminate-ovate, with the first joint as long as the others united ; 
rostrum arcuate, rather stout, extending to a little beyond the anterior cox, widened towards the base ; 
eyes moderately large, well-separated, acuminate below; prothorax transverse, bisinuate at the base, 
without ocular lobes; scutellum rounded; elytra rounded-triangular, separately lobate at the apex; 
pygidium not visible; mesosternum flattened, declivous; mesothoracic epimera narrow, ascending ; 
ventral segments ascending, 2 as long as 3 and 4 united; legs stout, femora each with a small tooth, the 
posterior pair reaching to a little beyond the apex of the elytra and subcarinate on their outer edge, 
tibial claw stout, tarsal claws minute. 
Type, Z. ruficauda. 
The single species from which the above characters are taken is nearly related to 
Archocopturus, differing from it in the much smaller, inferiorly acuminate eyes, the 
narrow, acuminate antennal club, and the equally unidentate femora. The prothorax 
has a few reflected metallic-green spots, as in A. regalis. 
1. Zygopsella ruficauda, sp. n. (Tab. III. figg. 16, 16 a.) 
Elliptic, robust, nigro-piceous or black, the antennal scape, the first joint of the funiculus, and the apical lobes 
of the elytra ferruginous ; above sparsely clothed with rather coarse, narrow, fulvous scales, the prothorax 
with a few reflected metallic-blue and green spots arising from the punctures; the elytra each with an 
arcuate median fascia, extending obliquely forwards to the base of the first interstice, a small patch near 
the middle of the suture, the suture itself thence to the base, a sharply-defined oblong spot on the fourth 
interstice at about one-third from the apex, and an indistinct humeral patch, white, the fulvous scales 
subseriately arranged and condensed into a stripe along the posterior half of the suture; the under surface 
with coarse, rounded, white scales, variegated with fulvous along the sides, the legs fulvous, mottled with 
white. Head densely punctate, depressed between the eyes above, the latter separated by abeut one- 
third of their own width; rostrum rugulose and subcarinate at the base, and sparsely punctate thence 
to the tip. Prothorax much broader than long, rounded at the sides, narrowed and strougly constricted 
in front; coarsely, densely punctate, the disc transversely convex and with a sharp, arcuate, median 
carina. Elytra wider than the prothorax, conjointly rounded at the apex, the apices each armed with a 
flattened, stout, blunt, dentiform process; crenate-striate, the interstices narrow, raised. 
Length 24-3, breadth 13-13 millim.
