208 THE ENTOMOLOGIST. 
March 8rd, 1912; and from EF. punctaria, March 20th, 1912. 
In the last three cases, the larve of the parasites passed the 
winter within their cocoons. I have also obtained it frequently 
from larvee of the summer brood of EF. puwnctaria. 
As hyperparasites I have bred Panargyrops aereus, Grav.,. 
July 20th, 1911, and June 26th, 1915, and also a very pretty 
little Chalcid belonging to the genus Cirrospilus, Westwood. 
Limbatus, Marsh.* 
This species seems to be confused with glomeratusin some 
collections, though the punctulate scutellum will distinguish it 
therefrom at a glance. Also glomeratus is smaller and has 
clearer wings, and, of course, the cocoons are quite different. 
A common gregarious parasite of the larve of Abraxas 
grossulariata, from which I have obtained numerous broods in 
May, the hosts having been sent to me by C. W. Colthrup from 
Dulwich and several localities in Kent and Sussex, and also by 
my brother from Wandsworth Common. No other host has yet 
been recorded, though it seems more than likely that there is at 
least a second generation in the year which cannot prey on 
larve of A. grossulariata. So far as my experience goes, the 
broods consist of from four to nine individuals, the sexes being 
about equally divided in each brood. Cocoons white with the 
faintest tinge of lemon colour, attached usually to a leaf of the 
food plant. 
From these cocoons I have frequently reared the hyper- 
parasites Hemiteles fulvipes, Grav., and Mesochorus angustatus, 
Thoms.

NOTES AND OBSERVATIONS. 
BISTON BETULARIUS, VAR. DOUBLEDAYARIA, AT WANSTEAD.— I noticed: 
this var. of our old familiar friend the ‘‘ Peppered Moth” on a wall 
here. I pay so little attention to the macros that I am unable to 
say if it 1s considered rare in the London suburbs, but I have not 
noticed one about here before.—A. THURNALL. 
CALLOPHRYS AVIS AT CANNES.—Immediately I had read Dr. 
Chapman’s note (p. 187) on this interesting butterfly, I wrote to 
Mr. Morris, who is collecting this year at Beauvezer, Basses-Alpes— 
a delightful spot at a comfortable altitude—for further information of 
his captures. This morning I have received the following account 
of his experiences with C. avis: “I took my C. avis at Cannes on 
an old terrace on the Pezou at Calycotema—there is no arbutus there ;
