THE ENTOMOLOGIST. 
Variety of Fidonia Piniaria. —On Saturday, the 21st 
inst., 1 took a fresh specimen of F. Piniaria, in which the 
right-hand pair of wings are those of a male, and the left- 
hand pair those of a female—or nearly so, their ground 
colour being orange; the antennae are also different, the 
right-hand one being as strongly pectinated as usual, while 
the other is quite plain. I suppose this would be called 
a case of gynandromorphosis. Is it not rather uncommon ?—

Pachetra leucophxea near Canterbury. —I have again been 
successful in taking six fine specimens of Pachetra leucophaea 
at sugar, near Stanting, the locality in which I took them last 
year. I may add they are very shy, for no sooner is your 
lamp near them than they are off.— G. Parry; Church 
Street , St. Paul's , Canterbury , June 10, 1873. 
The Gooseberry Grub. —I enclose a box of larvae which are 
very abundant in the gooseberry plantations here; on many 
bushes there is not a leaf left. Would you kindly name 
them? You will see two of them are of a different colour; 
these are not so plentiful. Can you suggest any plan of 
destroying them?— W. J. Skelton; The Bounds , Herne 
Hill , Faversham , June 17, 1873. 
[The larvas which Mr. Skelton sends are those of the 
gooseberry grub. A complete life-history of this destructive 
insect was published in the ‘Entomologist’ for August, 1841, 
and again in the ‘Letters of Rusticus’ in 1849; another, by 
Vollenhoven, in the ‘ Zoologist’ for 1862 ; and a fourth in the 
‘Field’ newspaper for 1867: each is accompanied bv illus¬ 
trative figures. I took infinite pains and pleasure in working 
out its destructive career, and a number of intermediate and 
subsequent writers have done me the honour to reproduce my 
labours in a variety of forms. The two specimens which 
Mr. Skelton describes as so different in colour are in the last 
skin, are not recognizable as the same insect unless by those 
who have studied its biography. Yollenhoven’s account is 
perfectly original; the others are very much repetitions one 
of the other, that in the ‘ Eutomologist’ being the authority 
followed in the others. Of course an insect so abundant and 
so destructive was sure to receive a great number of scientific 
names at the hands of entomologists, but after a variety of 
changes that of Nematus ventricosus, given by Klug in 1818,
