cases eastern plants have not been attacked, even when associated 
with western, but in one case at least, viz, Rhus toxicodendron, eastern 
plants have been extensively infested. 
The larvee feed on the flowers and also to some extent on the leaves. 
More rarely they feed on the hard fruits and seeds. The following list 
of the plants upon which the larva had been found prior to its work 
on Rhus will be of interest in this connection. It has been kindly 
prepared for me by Mr. Dewey, who read a short note on the subject 
at the late meeting of the Botanical Club A. A. A. S.:

* KE. angustifolium grows in the west but mostly in northern California and Oregon. 
The eggs are laid upon the plants or on any surrounding object. 
They are but slightly attached, bluntly ovoid, 0.3 millimetres wide and 
0.4 millimetres long. They are steel-gray in color, the shell white, with

The duration of the larval period has not been determined. Growth, 
however. is very slow and the period from the egg to the full larval
