1909] COOLIDGE — CHRYSOPHANID NOTES. on 
The bodies of the parasitized hosts were empty after emergence of the parasite, and 
externally with little or none of the usual cottony excretion. 
So far as known this is the only parasite of Schizoneura crataegi recorded in the 
literature.

CHRYSOPHANID Notes.— Zeroe Boisd. I have recently obtained an egg of this 
species from Mr. E. J. Newcomer, who observed the female ovipositing in Placer 
County, near Lake Tahoe, where zeroe occurs abundantly. Shape depressed spher- 
oid, the height not more than half the diameter; marked with large white walled 
polygonal or semicircular cells; considerably flattened at base, less so apically, 
where the net-work is small and low, the cells gradually enlarging as they approach 
the base; the micropylar area is deeply depressed, conspicuous. Color creamy- 
white. Deposited on the stem of the food-plant, which was not identified. Much 
smaller than the egg of gorgon and the indentations are much finer and eyener. 
Gorgon Boisd. In the December (1907) number of Psyche I gave a description 
of the egg of this species and remarked that the eggs which I had (laid in June and 
July) had not hatched at that time (October), although the normal hatching time was 
late August and September. I recently discovered this batch of eggs in a tin box in 
the drawer of my desk and I find but three of the nine eggs have disclosed larvae. 
This can probably be attributed to the cool and dry place in which the eggs were kept, 
as under natural conditions the eggs are particularly exposed to the warmth of the 
sun, being placed between the forks of its food-plant which only grows on the dry, 
hot hill-sides. ; 
Arethusa Dod. Mr. F. H. Wolley-Dod, the author of arethusa, writes me: “‘It is 
the same form listed by Skinner as phlaeas, though I overlooked the latter name 
when describing it. It is probably a local form of phlaeas, of which hypophlaeas 
is also a geographical race, occurring in Northern Europe.”
