Apparently a scarce insect, and confined to a limited district in Mexico. C. hopfneri 
is larger, broader, and more coarsely punctured than the allied C. pudescens and C. gres- 
soria; it closely resembles the var. 8 of C. gressoria. 
2. Chelymorpha pubescens. (Tab. VI. fig. 20, 2.)

A common insect in Mexico and Guatemala. <A variety occurs with the median 
discoidal spot small or obsolete, and the other spots much reduced in size. In the 
typical form the elytra have an oblong black mark midway between the humeral spot 
and the suture; but this patch is sometimes represented by one or two rounded spots. 
The lateral margins of the prothorax show no tendency to become black. Specimens 
from Matamoros Izucar, Teapa, and Temax have the elytra less gibbous than in typical 
C. gressoria, those from Cordova, Tapachula, and Zapote being almost intermediate. 
We figure a female specimen from Cordova, determined by Boheman himself.
