COPTURUS. 71 
Hab. Mexico (Koltze, in Mus. Dresden; Mus. Brit.), Vera Cruz (Chevrolat'), 
Toxpam (Sallé), Cerro de Plumas (Hége). 
This species has the elytra somewhat rounded at the sides, the prothorax long and 
conical, the femora not carinate externally, the femoral tooth long and stout, these 
characters separating it from C. mexicanus and other allied forms. The six specimens 
before me appear to be of the female sex, as they have the first ventral segment 
unimpressed ; they vary from 53-9 mm. in length.

2. Copturus bispinus, Bug. in litt. ’. 
3g. Ventral segment 1 shallowly sulcate down the middle, 5 broadly truncate at the apex; elytra obtusely 
angulate at the tip. 
. Ventral segment 1 unimpressed, 5 bluntly rounded at the apex; elytra each with a long sharp spine at 
the tip. 
Hab. Nicaragua, Chontales (Janson: 2); Costa Rica, San Carlos (Mus. Dresden : 
3); Panama, Tolé (Champion: 3 ).—Sourm America 1°, Bogota 3 (Mus. Dresden: ¢ ), 
Ecuador, Cayenne (Mus. Brit.: @ ). 
There can be no doubt that the sexes of this species differ in the way noted, such 
minute characters as the serrulate outer apical margin of the elytra, &c., being 
common to both male and female. Dr. Heller has been kind enough to communicate 
the type of C. scapha for examination. 
4, Copturus mexicanus. (Tab. V. fig. 5, 3.) 
Copturus mexicanus, Heller, Abhandl. Mus. Dresd. no. 11, p. 28’. 
3. Ventral segment 1 broadly depressed down the middle, 5 truncate and hairy at the apex. 
Hab. Muxico (Mus. Brit.), Cordova (Sallé), Oaxaca (coll. Faust), Teapa (H. H. 
Smith); Guatemata, Teleman and Cubilguitz in Vera Paz (Champion); Nicaraaua, 
Chontales (Janson). 
The few specimens of C. mexicanus before me, including one of the types, are all of 
the male sex. The single (worn) example from Chontales has the elytral interstices 
sharply costate, and it may belong to a different species. 
5. Copturus centralis, sp. n. (Tab. V. fig. 6.) 
Copturus centralis, Chevr. in litt. 
Subovate, flattened above, nigro-piceous ; clothed with small intermixed ochreous (or flavo-cinereous) and 
blackish (or fuscous) scales, the ochreous scales on the prothorax condensed into three irregular vitte
