for the corresponding months of 1919-20. In the summer of 1920, which 
fo'lowed an unusually severe winter, the writer could find only one 'arva 
of this pest. This was a parasitized specimen (fig. 96, C) found on June 
3 on clover, from 
which eight speci- 
mens of Rhyssalus 
loxoteniae Ashm.® 
were reared. From 
a larva taken on 
beans on August 
22, 1919, another 
parasite, Aleiodes 
intermedius Cress.,° 
emerged on Sep- 
tember 4 
When undis- 
turbed, the larva of 
Plathypena scabra 
rests quietly on the 
leaf and is incon- 
spicuous by reason 
of its pale green 
colon (hes 97, 4B); 
but when the plant 
is Shaken, the larva 
may drop to the 
ground and squirm 
back and forth for 
some time, or it 
may remain sus- 
pended in mid-air 
by a fine silken 
thread. The older 
larvae are vora- 
cious feeders. They 
eat entirely thru 
a leaf (fig. 97, A), 
and sometimes 
make large holes 
in the pods (Plate 
LXX, 5). 
The pupa (fig. 
96, A) is mahogany
