Family ALEURODIDiE. 



This little family, for which we have no popular name, contains only a very 

 few small species in New Jersey. They somewhat resemble plant lice in 

 appearance, but are covered with a fine whitish powder or flour. In the larval 

 stage they somewhat resemble scales, but as adults both sexes have four well- 

 developed wings

Family COCCIDiE. 



These are the " Scale insects " broadly speaking, characterized by a degraded, 

 larva-like form in the female and by the presence of a single pair of wings onl)- 

 in the male, which has also a complete metamorphosis, a long anal style or 

 filament and an extra pair of eyes replacing the mouth, which in this sex is not 

 used at all for feeding purposes.
