70 HETEROMERA. 
testaceous, the femora piceous towards the apex, the latter strongly clavate outwardly, the tibie and tarsi 
very slender, the apices of the femora and the tibie on all sides sparsely clothed with long erect hairs ; 
the tibiee each with a single sharp short spur. / 
Length 7-8} millim.; breadth 13-17 millim. (¢ @.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Var. The elytral impressions finer and shallower; the apical portion with very much shallower strie, which, 
the first excepted, do not extend so near to the apex, and feebly convex interstices. 
Hab. Nicaracva, Chontales (Janson). 
Seven examples of the type and one of the variety. The latter differs very consider- 
ably from the others in the intensity of the elytral sculpture, but it doubtless repre- 
sents no more than a local form of the same species. The central sheath of the 
cedeagus of the male terminates in a broad sharply-angled triangular piece. C. swlei- 
colle is allied to C. decoratum, C. calcaratum, &c., but differs from these in its relatively 
narrower and more elongate shape, longer head, brilliant metallic green or golden- 
green colour, &c. The elytral sculpture, as in C. vitticolle, somewhat resembles that 
of certain species of Strongylium. The thorax is not only transversely grooved 
towards the base, but has another transverse deep eroove on each side of the disc about 
the middle. 
A typical specimen from the. Volcan de Chiriqui is figured. 
** Antenne with the apical joint very elongate in the male; upper surface flavo- 
testaceous, the prothorax with a black stripe on each side, the elytra spotted. 
4, Colparthrum vitticolle. (Tab. III. fig. 22, ¢.) 
Elongate, yellowish-testaceous, shining ; the prothorax with a long sinuous piceous stripe on each side; the 
elytra with a common broad transverse band at the base (not extending to the humeral callus or lateral 
margin), another about the middle (connected with the anterior one along the suture, extending to the 
lateral margin, and angulate on its lower edge), and an ill-defined oblique patch (connected at the suture) 
towards the apex, dark brown, the bands reddish within and enclosing a broad transverse yellowish one. 
Head with a broad and deep transverse depression between the eyes and a few setiferous punctures at 
the sides and behind, for the rest smooth, the eyes moderately large; antennee ( ¢ ) flavo-testaceous, long 
and very slender—the apical joint rather longer than joints 8-10 united, the latter elongate ; prothorax 
cylindrical, very much longer than broad, the sides completely immarginate, much rounded anteriorly, and 
compressed and strongly constricted behind, the hind angles prominent but not acute, the disc with a deep 
transverse groove behind, the surface quite smooth; elytra with prominent shoulders, widest about the 
middle, with regular rows of closely-placed deep foveate impressions to a little beyond the middle and 
thence for some distance deeply striate (with fine crenate punctures), the striew (the first excepted) not 
continued to the apex, the interstices flat to about the middle and at the extreme apex, for the rest 
convex, the third, fifth, and ninth each with two or three very fine setiferous punctures towards the apex, 
the apices obtuse ; beneath and the legs yellowish-testaceous, the latter long; the femora clavate towards 
the apex, quite slender at the base, and smooth and glabrous; the tibie and tarsi long and very slender, 
the former thickly clothed with long fine erect hairs within and smooth without and without distinct 
spurs. 
Length 7 millim.; breadth 13 millim. (¢.)
