and was found to contain a dipterous puparium about the size of that 
of Exorista griseomicans, and from a hole in its anterior end some insect- 
had emerged. No trace of the pupa skin of the Chalcis could be found, 
however, and I am of the opinion that the label was incorrect. 
In all, 260 specimens of Chalcis ovata were reared, and Hanes of issu- 
ance will appear from the following table:

It will be observed from this table that no rearings were made in the 
spring of 1896 from cocoons taken the previous fall or from cocoons 
taken in the early spring. From this fact it seems reasonably certain 
that this insect hibernates in the adult condition. 
We have no positive evidence that it possesses secondary parasites, 
but specimens of Dibrachys boucheanus have been reared from pup of 
the Orgyia, the first inhabitant of which we do not know, but it may 
very well have been this species. 
Pteromalus cuproideus n. sp.! 
On October 5, 1895, two specimens of this parasite were reared from 
the 100 Orgyia cocoons collected September 10 to ascertain the per- 
centage of parasitism. All of the species belonging to the section of 
the genus Pteromalus, to which this belongs, are primary parasites on 
lepidopterous larvee, and we may therefore safely consider that this 
species is a primary parasite of the larva of the tussock moth. 
Cratotechus orgyie (Fitch). 
The adult of this insect has been reared only by Dr. Fitch. In his 
Second Report on the Noxious, Beneficial, and Other Insects of the 
State of New York (separate edition, p. 216, 1856) he gives the follow- 
ing account of this insect: 
Lonce gathered two of these caterpillars, which I placed, with some leaves, in a box. 
Two days afterwards one of them was found to be dead, and the other, being lively 
and vigorous, was removed to another box. Next day what appeared to be the ends 
of little worms were seen protruding from the body of the dead caterpillar. Upon 
the following day these worms were found to be seventeen in number. They had 
all left the dead carcass of the caterpet and just above it on the side of the box
