182 [January, 
I am inclined to think that the apparent double-broodedness of Argyrolepia 
Duhriscona is only caused by a retarded development ; and the appearance of 
EupcBcilia suhroseana every month or six weeks from May to September may be 
from the same cause. — Chas. G. Baeeett, Haslemere, 13th Novemher, 1867. 
Curious food of Abraxas grosculariata. — In the middle of May I casually noticed 
a number of larvse of Abraxas grossulariata feeding on the Orpine (Sedum telepMum). 
That this was not caused by scarcity of their natural food was clear, since there 
was plenty of blackthorn growing close by. Being curious to see how they would 
turn out, I secured the larvae and fed them up on the Sedum, and had the pleasure 
of breeding as ordinary a lot of imagoes as one could easily see, with, indeed, less 
than the ordinary amount of variation. 
I found a very young larva on the same plant while collecting larvae of Hypono- 
meuta vigintipunctata this autumn, from which it woxild appear that they feed up 
from the egg upon it. 
This selection of a food-plant seems as curious as the instance recorded by 
Mr. Chapman, in which the larva of the same species was found on Cotyledon 
umbilicus, on Ailsa Craig. Mr. Syme, however, tells me that some botanists 
include the currant in the same group as the Saxifrages, to which both these plants, 
I believe, belong. — Id. 
Acentropus niveus and other Lepidoptera at Haslemere. — On June 10th, passing 
a fir wood on one of the slopes of Hindhead, I dismounted to have a look for Scotosia 
undulata. It was a fortunate thought, for I soon found it in plenty. It was Hot, 
as I expected, on the tree trunks, but hiding among Vaccinium and the bramble and 
holly bushes, and was very restless and difficult to approach. However I secured 
plenty, with some Hypena crassalis not over fine, and Penthina sauciana among the 
Vaccinium. 
After travelling for some hours among the hills I arrived at Frensham Pond, 
and went to work to find Acentropus niveus. Paraponyx stratiotalis swarmed 
along the margin of the pond, and Hyd/rocampa stagnalis occurred, but for some 
time I could find only drowned specimens of niveus. 
At last, however, I found some faggots sunk with stones in one corner of the 
pond, leaving some of the twigs above water, and on the under-side of these twigs 
niveus swarmed, sometimes clustered four or six in a bunch. They were very 
sluggish, and, if knocked off a twig, only buzzed along the surface of the water till 
they found another, and if accidentally immersed in moving the twigs, took no 
notice whatever of the ducking. 
At sunset I reached a marsh about a mile from the pond, and finished up my 
day's work by taking about fifty Eudorea pallida flying among rushes and long 
grass. — Id. 
Note on Diadema BoUna, Linn. — As there appears to be some uncertainty as 
to this butterfly being indigenous in South America, I wish to note a new locality 
for it. In the Eoyal Dublin Society's Museum we have a specimen from Trinidad. 
There is nothing remarkable in this locality, except that all the known American
