- COPTURUS. 8) 
flattened prominence on each side, between the cox, hollowed down the middle. Legs short; femora 
| unidentate, the intermediate and posterior pairs carinate externally. 
Length 23-3, breadth 14-14 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Four specimens. Smaller than C. cincticollis, the prothorax without an oblique white 
streak on the flanks, the elytral vestiture seriately arranged, the markings different, the 
under surface without transverse black spaces at the sides, the rostrum less elongate, 
the joints 2-4 of the funiculus much shorter, the mesosternum with a flattened 
prominence on each side. 
36. Copturus albidus, sp.n. (Tab. VI. fig. 3.) 
Elliptic, black, the antenne and tarsi fusco-ferruginous ; densely clothed above and beneath with white scales, 
the scales on the upper surface fine, the elytra each with an indeterminate, rounded, blackish patch on 
the disc towards the apex, a small spot on the humeral callus bare. Eyes extremely large, very narrowly 
separated. Rostrum strongly arcuate, rugose and carinate at the base. Joint 2 of the funiculus nearly 
as long as 3-7 united, 3 and 4 equal in length, 5 short, 6 and 7 transverse. Prothorax short, narrowing 
from the base, feebly constricted in front, with broadly rounded ocular lobes; densely, finely punctate. 
Elytra depressed along the suture anteriorly, finely punctate-striate, the interstices broad, flat, and 
densely punctulate. Mesosternum flattened anteriorly, with a stout angular prominence on each side 
between the middle coxe. Metasternum with a smooth, deep, foveiform impression in front, limited 
posteriorly by a short curved ridge. Legs short; femora linear, unidentate beneath, the intermediate 
and posterior pairs finely carinate externally. 
Length 42, breadth 22 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Two specimens. This insect has the meso- and metasternum formed as in C. (Cypho- 
copturus) tristis, Heller, but the legs are much more slender, and the femora are not 
widened at the base. The dense white vestiture of the entire surface, a darker patch 
near the apex of each elytron excepted, separates C. albidus from all the other forms 
here described. ‘The tip of the rostrum is received in a deep foveiform cavity in the 
mesosternum, much as in many Lechriops. 
The following species differ in various respects from the typical members of the 
genus Copturus, but they can remain under it for the present :—

Rhomboidal, flattened above, shining, black, the antenne ferruginous ; the vestiture rather close: the head 
with a line around the eyes (abraded above), the basal half of the rostrum, and the prothorax with the 
sides broadly and a narrow faint median vitta, fulvous, the rest of its disc black ; the elytra black, with
