COPTUROMIMUS.—COPTUROMORPHA. 65 
bare humeral callus (connected with the first two fascize), ochreous, and a spot at the sides towards the 
apex white, the rest of their surface with blackish scales; the under surface thickly clothed with oval 
white scales, the legs with narrow white scales. Eyes very large, subcontiguous. Rostrum rugulose 
and carinate at the base. Joint 2 of the funiculus elongate, as long as 3 and 4united. Prothorax short, 
gradually narrowing from the base; densely, finely punctate. Elytra short, rounded-triangular, blunt 
at the tip; punctate-striate, the interstices flat and rugulose, the humeral callus smooth. Meso- and 
metasternum slightly depressed between the intermediate coxw. Legs short; femora feebly unidentate 
beneath, the two posterior pairs carinate externally, the area on the anterior pair very finely strigose ; 
tibize almost straight. 
Length 23-3, breadth 12-12 millim. 
Hab. Mexico, Toxpam in Vera Cruz (Sallé); Panama, Volcan de Chiriqui 
(Champion). 
Six specimens from Panama and two from Mexico, the latter somewhat worn. A 
small species, with three vittee on the prothorax, and three transverse fasciz on the 
elytra, ochreous, the fascize connected by a whitish or cinereous sutural stripe, the 
elytra also with a white spot at the sides towards the apex.’ The allied C. ochro- 
fasciatus, Heller, is very much larger, and has a diamond-shaped ochreous patch on 
the disc of the prothorax and the elytral fascia disconnected, the elytra themselves 
more finely striate. 
COPTUROMORPHA, gen. nov. 
Joint 2 of the funiculus not or very little longer than 1; mesosternum in the typical forms excavate and with 
the excavation limited on each side by an oblique ridge; metasternum usually more or less hollowed 
between the middle coxe; ventral segments rapidly ascending; legs short; femora not or obsoletely 
dentate beneath *, the anterior pair with an inconspicuous or faint, impunctate, finely strigose area on 
their front face. 
Type, C. interrupta. 
The species referred to this genus (which will probably include Copturus musicus, 
Kirsch, from Peru) are all of small size, the typical forms having the mesosternum 
almost as deeply excavate as in Pecilogaster and the femora unarmed beneath. The 
relatively shorter second joint of the funiculus separates them from Copturominuws. 
They may be grouped thus :— 
a. Prosternum with a conical tubercle behind each anterior coxa, similar to that on 
the coxa itself; mesosternum deeply excavate and obliquely bicarinate ; meta- 
sternum hollowed in the middle in front. . . . . . . . 1. 1). «Species 1-4. 
6. Prosternum without tubercles behind the anterior coxe. 
a’. Meso- and metasternum shallowly depressed between the middle coxe. . . Species 5. 
6°. Mesosternum only depressed between the middle coxe . ..... ~~. Species 6, 7. 
* In a single minute species from Chiriqui apparently belonging to this genus, too immature to describe, the 
femora are obsoletely toothed.
