In 1908, Dr. Howard suggested that it would be desirable 
to segregate the aphis-feeding species of Aphelinus into a new 
genus, but he never carried out his suggestion for the reason, 
I believe, that he was not entirely sure of the characters of the 
type species of the genus. Since that time Kurdumoff has given 
a synopsis of the European species of Aphelinus, and has shown 
clearly that the genotype, A. abdominalis (Dalman) is an aphis- 
feeding species. It is, nevertheless, still desirable to divide 
Aphelinus, but now it is apparent that coccid-feeding species
