OBSERVATIONS ON PHYSIODES NYCTEIS. 
By Cuas. RUMMEL, Newark, N. J. 
During 1918 Physiodes nycteis was found in abundance over 
the section of the Orange Mountains from Milburn to Patterson. 
Adult specimens appear from the middle of June to August. 
The species is single brooded. Its food plant, the wild sunflower, 
Helianthus divaricatus, is generally distributed over the Orange 
Mountains. The larve begin to hatch from their eggs July 1, 
feeding in colonies at first. After the second molt, in August, 
when about one eighth inch in length, they go into hibernation 
among dead leaves on the ground. They reappear in early 
spring and attain full growth from May 20 to June 10. The 
larve are black and spiny. Colonies of fifty or more may be 
found on one leaf, eating only the soft tissue on the upper and 
underside and leaving the skeleton which shrivels and appears as 
having been exposed to great heat. The chrysalids are very 
much like those of Melitca pheton, only smaller in size. The 
adults are at their best from June 10 to 25.
