(16. 1 /'/,. nacaspift, Cooley and Ckll., will be a new genus to include P. nyssat, chiru 

 eugenice, etc, hitherto placed in Chionaspis. Mr. Cooley and the present writer agree 

 that these forms have no genetic relationship with genuine < 'hionaspis except through 

 Aulacaspis and Diaspis. 1 leave Mr. Cooley to publish the generic characters and 

 classify the species. 



(17.)" Mr. i !ooley is responsible for the synonymy. 



(18.) According to W r. Cooley, 



(19.) Mr. Cooley finds that specimens of C. prunicola from Mr. Maskell are Dia 

 amygdali. It is jus) possible that Maskell accidentally mixed the ZWaspts with a*genu- 

 ine Chionaspis, however, and that prunicola may still be valid. 



(80.) This could very well pas> for Aspidiotw cmcylus, did it not have a Diaspis male 

 scale! D. pirieola, in Europe, was long confounded with Aspidiotus ostreatformis.
