Aleurodes (Aleyrodes) LATR. 
Note.—Genus Alewrodes (Aleyrodes) Latr., seems rightly to be 
referred to this family by BurmetstEr. Metamorphosis complete, 
as in males of Cocci; pupa quiescent, folliculate. Also anterior 
wings sufficiently similar to wings of Cocci. But the number of 
wings (four), which are not wanting in females, the rostrum too, with 
which, as it seems, the males also are furnished, seem to indicate 
the separation of this genus from the Coccina, and accordingly 
LATREILLE joined it with the Aphidz, and lately, Hartie with the 
Psylle ; Westwoop, however, to avoid a difficulty, preferred creating 
a small family from the single genus.
