C. immunita, and C. immunda, Boh., to the synonymy. Cassida fuliginosa, Oliv. (Ent. 
vi. no. 97, p. 971, t. 1. fig. 8), from Guadeloupe, doubtfully placed by Boheman as a 
synonym of the South-American Coptocycla cruciata (Linn.), belongs almost certainly to 
the dark variety of our species (=C. trabeata or C. immunita, Boh.). I have examined 
the type of C. immunda, Boh.: it is a pale form of C. signifera, and has been received 
with typical examples from Yucatan, Teapa, &c.; specimens of C. hamulata, Boh., from 
San Domingo scarcely differ from it. We figure a typical C. signifera from Teapa, also 
a specimen of the var. « (trabeata), from Temax, and of the var. 8 (timmunda), from 
Teapa.

Coptocycla lecontei, Crotch, Proc. Acad. Phil. 1873, p. 79°. 
Hab. Norto America, Arizona 1.—Mextco, Villa Lerdo in Durango, Tupataro in 
Guanajuato, Yautepec in Morelos, Chilpancingo in Guerrero, Misantla (Hége), Ventanas 
in Durango (Forrer), Guanajuato, Istapan (Sallé), Tepetlapa in Guerrero (H. #. 
Smith). 
This is probably only a well-marked variety of C. signifera, Herbst (=guttata, Boh.) ; 
but as it is fairly constant on the central plateau of Mexico and in Arizona, where it 
appears to replace C. signifera, I retain it as distinct. C. lecontet chiefly differs from 
C. signifera in having the black markings on the disc of the elytra completely separated 
from the humeral patch by an oblique yellow stripe; it is also more elongate and 
larger, and has a sharply defined rounded black spot on the yellow discoidal markings 
near the base. Some specimens from Vera Cruz, Tapachula, and Nicaragua are almost 
intermediate between them; and in one from Zapote, Guatemala, the humeral patch 
is disconnected on one elytron and connected on the other. In typical C. signifera the 
yellow streak exterior to the humeral callus extends about halfway across the dark 
humeral ramus; but in some specimens of the vars. immunda and hamulata, Boh., the 
humeral patch is disconnected. Our figure is taken from a specimen from Tupataro, 
agreeing with one from -Arizona kindly communicated by Dr. Horn. |

Apparently a close ally of C. signifera, var. trabeata.
