 in the more elevated parts.

Mulsant recognizes four varieties of this widely dispersed and sometimes very 

 abundant species. Thus : — 



Var. A. Elytra without spots. 



Var. B. Elytra with the scutellar spot only. 



Var. C. Elytra with a scutellar spot, and some spots ia addition to the normal pattern. 



Var. I). Elytra marked with black spots irregularly placed. 



The var. B is rather common ; we have seen it from Guanajuato, Oaxaca, Etla, 

 Puebla, Cordova, Tenango del Valle, and Amecameca. But a variety in which the 

 scutellar spot is wholly absent is not among the very numerous specimens that have 

 come under my notice ; nor have I seen varieties corresponding to vars. C or D, with 

 more than the normal number of spots, that is to say three basal and three apical 

 spots on each elytron besides the very small scutellar dash on the suture. Varieties in 

 which one or all of the three basal spots are wanting or reduced to points are common. 



Subfam. COCCINELLIDFS. 



This subfamily contains really only the two genera Adalia and Coccinella, for 

 Mulsant's Adonia is by most authors now generally merged in Hippodamia, and 

 the genus Cisseis, containing but one species, has been shown by Crotch to be a 

 Verania. Nesis, Mulsant, has no character whereby it can be separated from the 

 Halyziides, and Bulcea is only separable from Coccinella by having simple instead of 

 " appendiculate " claws. 



The only question now is whether it is worth while maintaining the Halyziides in a 

 separate division, or as a subfamily at all.
