516 RHYNCHOPHORA. 
(the anterior pair bidentate in C. longiusculus and C. quadricostatus), the posterior pair not extending 
beyond the apex of the elytra; anterior tarsi of the ¢ clothed on each side with long, projecting hairs. 
Ceelosternus longiusculus, Boh., is taken as the type of this genus, which also includes 
various other Tropical-American forms. These insects differ from Macromerus in 
having the legs shorter, the anterior pair less elongated in the male, the rostrum 
shorter and stouter, reaching to about the middle of the intermediate coxe, and the 
mesosternum horseshoe-shaped or triangular. ‘he relatively longer second ventral 
segment and the shorter and less attenuate rostrum separate Cophes from Celosternus 
as here understood. ‘The eyes are very large in C. gibbus. The anterior tarsi of the 
male are dilated in C. longiusculus and narrow in C. bifurcatus. C. quadricostatus 
and C. hieroglyphicus have the anterior legs of about the same length in the two sexes. 
C. cognatus has narrow episterna and it may have to be removed from Cophes. 
1. Cophes longiusculus. (Tab. XXV. figg. 21, 21a, 3.) 
Ceelosternus longiusculus, Boh. in Schonh. Gen. Cure. iv. p. 217". 
Hab. Mexico (Mus. Brit.), Vera Cruz (Chevrolat '), Playa Vicente (Sallé); Nicaracua, 
Chontales (Janson). 
The six specimens of this species received by us vary from 53-94 millim. in length. 
The anterior femora are bidentate, the others unidentate, the outer tooth on the 
former being sometimes wanting. ‘The tarsi are long in both sexes; the anterior pair 
of the male have the two basal joints elongated, dilated, and clothed with long, 
projecting hairs. The antennal club is oblong-ovate; the second joint of the funiculus 
is as long as the first, the others short. 
2. Cophes asperatus, sp.n. (Tab. XXV. figg. 22, 22a, ¢.) 
Oblong-ovate, black, the antennze obscure ferruginous ; above thickly clothed with reddish-brown scales, the 
prothorax usually with a more or less distinct, rather broad, subcruciform, whitish median vitta and the 
elytra slightly mottled with whitish on the disc, the scutellum ochreous or white, the elytra also with 
scattered short decumbent setw; the vestiture of the under surface and legs sparse, reddish-brown, 
intermixed with white. Head densely, rugulosely punctate, flattened between the eyes, which are rather 
prominent and widely separated ; rostrum (¢) a little longer than the prothorax, curved, moderately 
stout, slightly dilated, rugosely punctate, and feebly 5-carinate at the base, thickly punctate at the tip, 
(2) longer, rugosely punctate at the base and sparsely so thence to the apex, the antenne inserted at 
the middle in the ¢ and nearer the base in the 9, joints 1 and 2 of the funiculus elongate, subequal, 
3-7 short, the club ovate. Prothorax transverse, rounded at the sides anteriorly, constricted and narrowed 
in front; sparsely granulate, the interspaces densely, finely punctate, the disc shallowly canaliculate. 
Scutellum flattened. LElytra a little wider than the prothorax, subparallel in their basal third, flattened 
along the suture anteriorly ; coarsely seriate-punctate, the punctures becoming finer and placed in shallow 
strie towards the apex, the interstices rather convex and sparsely granulate, the alternate ones 
‘moderately raised. Beneath coarsely punctate. Legs moderately long; femora clavate, sharply unidentate ; 
anterior tibis of the ¢ widened on the inner side to about the middle and concave thence to the apex, 
mucronate at the inner apical angle; anterior tarsi of the ¢ with the two basal joints dilated, elongate, 
and clothed with very long projecting hairs. 
Length 6-9, breadth 23-4 millim. (¢ 9.)
