Adiastola americana n. sp. 1 
Three specimens of this species, two females and one male, were 
reared November 6, 1805, from cocoon masses of Orgyia under observa- 
tion. This species also is likely to be a parasite of Pimpla inquisitor. 
Otacustes periliti Ashm. 
A single specimen of this spe- 
cies issued from a cocoon of Mete-

species was reared from the same

Allocota thyridopterigis ( Kiley). 
A single specimen of this in- 
sect, which is commonly reared 
from the bags of the bagworm 
and which was firsl described by Kiley as a parasite of this species, 
was seen crawling rapidly over the trunk of a poplar tree in Septem- 
ber, 1895, investigating Orgyia cocoons. It was doubtless attracted by

site of Pimpla conquisitor, we may safely put it down as a secondary 
parasite in the case of Orgyia leucostigma, the more especially as no
