COLLOPS. 
Collops, Erichson, Entomographien, p. 54. 
Megadeuterus, Westw. Trans. Ent. Soe. ii. p. 98. 
The species of this genus have apparently ten-jointed antenne, the second joint 
being very small; the third is distorted, and in the male much enlarged, as is well 
shown in Tab. VI. fig. 21. 
1. Collops bipunctatus. 
Malachius bipunctatus, Say, Journ. Ac. Nat. Sci. Phil. iii. p. 185 ; Amer. Ent. iii. t. 487. 
Collops bipunctatus, Erichs. Ent. p. 55. 
Hab. Unirep States, Arkansas 1.—Mextico 2 (Sturm, coll. Sallé). 
2. Collops aulicus. (Tab. VI. figg. 21, 22.) 
Collops aulicus, Erichs. Ent. p. 551. 
Hab. Mexico! (Sallé), Toluca, Puebla (Sailé), Guanajuato (Duges, coll. Sallé). 
The figures are taken from specimens in Sallé’s collection, without exact locality, 
from Mexico. 
3. Collops tricolor. 
Malachius tricolor, Say, Journ. Ac. Phil. iii. p. 182; Amer. Ent. iii. t. 48’, 
Collops tricolor, Erichs. Ent. p. 47°. 
Hab. United States, Mississippi —Mextco !2, Etla, Parada (Boucard, coll. Sallé), 
Puebla (Sallé), Oaxaca (Hége). 
4. Collops femoralis. 
Nigro-ceeruleus ; antennarum basi, ore, prothorace, pedibus basi abdomineque rufis, elytris subviridi-ceruleis. 
Long. 53-6 millim. ¢ 9. 
Hab. GUATEMALA, near the city (Champion). 
I should scarcely have given this specific rank but that the differences of several 
other species of Collops are mainly those of colour, and all the specimens collected by 
Champion near the city of Guatemala agree in having the legs red as far as the knees. 
With these a single specimen, from Guatemala, in Sallé’s collection agrees; and they 
appear to be a trifle longer and to have the elytra more of a green tint than they 
are in C. tricolor. It therefore appears to be at least entitled to a name as a local 
race or variety. 
5. Collops geminus. 
Collops geminus, Erichs. Ent. p. 58°. 
Hab. Guatemata, Chiapas (SaJlé), Duefias, Guatemala city (Champion); NicaRAGua
