Fic. 10.—A spidiotiphagus citrinus (Craw.)—greatly enlarged (from Insect Life). 
Aspidiotus aurantii Maskell, var. citrinus, from San Gabriel, Cal. Mr. 
G. W. Johnson has also sent me six specimens reared at the Illinois 
State Laboratory of Natural History from Aspidiotus ficus occurring 
on Citrus decumana in the university greenhouse. Professor Berlese 
has reared this species in Italy from an Aspidiotus on Acacia longifolia 
and from Diaspis rose.

Ratzeburg’s genus Coccobius includes, as will be seen from the 
synonymical list, certain species of Coccophagus and certain species of 
Aphelinus as well. His antennal figure is that of Aphelinus, but his 
descriptions include species which apparently belong to Coccophagus, 
notably C. notatus. 
In this genus the antenne are 8-jointed, the scape rather short and 
stout; pedicel one-third the length of the scape and about the same
