206 RHYNCHOPHORA. 
the suture of the elytra and the base of the prothorax, the elytra also with an 
interrupted, oblique fascia at one-third from the apex and various scattered streaks of 
similarly-coloured scales on the anterior half of the disc and at the tip. 
2. Nertus eneus, sp.n. (Tab. XII. fige. 4, 4a, 3.) 
Elongate, narrow, fusiform, shining, black with a bright zneous lustre; somewhat thickly clothed with long, 
coarse, hair-like, ochreous scales, the scales on the elytra clustered into fascicles over the whole of the 
surface, the prothorax with a bare space down the middle. Head finely punctate; rostrum almost 
straight, depressed at the base, rather longer than the head and prothorax, sparsely, finely punctate ; 
joints 2-7 of the funiculus short, rapidly widening outwards, 3-7 transverse. Prothorax broader than 
long, gradually narrowing from the base, the sides rounded anteriorly, feebly constricted in front; closely, 
finely punctate, except along a narrow space down the middle. Elytra elongate, of about the same width 
as the prothorax, narrowing from near the base, the apices narrow and separately rounded; finely 
punctate-striate, the interstices flat, here and there with clusters of finer squamigerous punctures, for the 
rest smooth. Prosternum shallowly sulcate, the intercoxal portion as wide as the apex of the rostrum. 
Ventral segments sparsely, finely punctate, 1 flattened and rugulosely punctate down the middle, 
5 shallowly arcuate-emarginate at the apex. Femora deeply excised towards the apex, the anterior pair 
triangularly dilated. Tibie hairy at the apex, the anterior pair strongly sinuate within and with the 
apical spur long and broadly dilated, the posterior pair bisinuate. Tarsi clothed with long hairs, 
Length 8, breadth 3 millim. (<¢.) 
Hab. Costa Rica, Savanillas de Pirris (Underwood). 
One specimen. This insect is of about the size and shape as Cholus tenuis, but may 
be readily distinguished from it by the ascending mesothoracic epimera, the slender, 
almost straight rostrum, &c. The spur of the anterior tibic is developed into a long, 
flattened process, a character probably peculiar to the male sex. 
STRONGYLOTES.

p. 239. 
Three species of this Tropical-American genus have been described, their dis- 
tribution ranging from Mexico to Brazil. They mainly differ from Nertus in their 
parallel-sided general shape. 
1. Strongylotes brachialis, 
Strongylotes brachialis, Boh. in Schénh. Gen. Cure. viii. 1, p. 75°. 
Hab. Mexico (Mus. Imp. Russ.1), 
Unknown to me. “Black, with rufo-testaceous antenne and legs, almost glabrous 
above, squamose beneath; the prothorax thickly, rugosely punctate and feebly 
carinate ; the elytra deeply striate, with narrow, convex, almost smooth interstices ; 
the femora obtusely dentate.”
