LESTODIPLosis Kieff. 
This genus, as recognized by us, is easily separated from all other 
Diplosids by the very characteristic triangular lobe at the base of 
the slender basal clasp segment. The dorsal plate is rather long, 
rather deeply and triangularly emarginate, the lobes being nearly 
parallel and broadly rounded, while the ventral plate is long, rather 
broad and narrowly rounded apically. Species referable to this 
group are rather small, ranging from .75 to about 2 mm in length, 
usually yellowish or reddish, though a few are brownish. 
Species of this genus are very frequently bred from various 
galls and in certain cases at least, are probably zoophagous. ‘This 
is undoubtedly true of L. grassator Fyles, and presumably so 
of a number of other species, though it will be observed by refer- 
ring to the following records, that a considerable number of species 
have been bred from flowers or rolled leaves. These may be en- 
tirely responsible for the vegetable deformities or partly so, living 
as commensals, or it is possible that they may be the cause of 
certain malformations. It is impossible, in the present state of our 
knowledge, to make definite statements respecting the habits of 
these species. It is worthy of notice, however, that those reared 
from different plants, present variations which lead us to regard 
them as distinct species. Certain species in the following table are 
given in two divisions as having the wings either hyaline or spotted. 
This is due to the fact that it is very difficult to draw a sharp line 
between spotted and unspotted wings in cases where there are 
numerous gradations. Furthermore, females which are not repre- 
sented in the following table, frequently have spotted wings, while 
their consorts have the organs of flight hyaline. This character, 
though variable, is a very convenient one upon which to make pri- 
mary divisions.

a length % greater than its diameter; bred from fusiform galls on
