with a small green chrysomelid beetle. Both the adult beetles and 
their grubs feed voraciously on the willow foliage. Both leaf #4 and 
#10 in the 1958 series showed considerable chrysomelid damage. 
Tingid eggs in some numbers seem to be destroyed incidentally by 
their beetle competitors. 
In these collections two specimens had parasites attached. The 
first was collected on July 28, 1957 with a white ovoid mite about 
.2 mm. wide and .4 mm. long clinging to the right side of the body 
under the elytron and above the leg base. It was attached at the joint 
between the metathorax and the abdomen. 
There was a female lace bug in the collection for June 8, 1958 with 
a grub-like, whitish parasite projecting from the right side of the 
abdomen. Dissection revealed that the parasite was about .7 mm. 
long and .2 mm. wide. It lay transversely in the abdomen of the host 
and about half of the parasite extended beyond the body wall of the 
lace bug in the pleural region. Lack of distinctive features made it 
impossible for me to identify.
