menon is that the larva, finding its efforts to “screw” or draw together the edges of 
the leaflet unavailing, is prompted by its instinct to cut the midrib, thereby rendering 
the leaflet flaccid and easily contorted.—John Peers; 64, Butter-Market Street,

Zelleria hepariella and Z. insignipennella the same Species.—During my stay at 
Witherslack, in Westmoreland, I took a good number of specimens of Zelleria 
hepariella and of the insect named Z. insignipennella. I had long suspected the 
were identical, from having taken several intermediate forms, until I at last beat out of 
a yew one of each in cop., which confirmed my previous suspicions, and Z. insignipen- 
nella must therefore be struck out of our list. I took the variety Z. Haighii very 
scantily, and always small compared to some of the specimens of Z. insignipennella, 
which are full half an inch across the wings.—J. B. Hodgkinson ; 31, Christchurch 
Street, Preston. 
Affinities of Acentropus. By Epwin Brown, Esq.* 
I Have here, at the risk of wearying the reader, brought down the 
bibliography of the genus Acentropus, from the first published 
description of a species in 1791, to the present time ; I will now draw 
a few conclusions in as concise a manner as I can. 
Among the specimens described by authors under the name of 
Acentropus niveus, I believe there are confounded at least three 
species :— 
1. Acentropus nivens = A. Garnonsii of Curtis. To this species 
will belong the specimens obtained by Mr. Dale and by Mr. Curtis at 
Glanville’s Wootton, and by. myself at Burton-on-Trent. The male 
has been well described and figured by Curtis. The female is 
apterous, and is furnished with long silky white fringes to its hinder 
tibie. 
2. Acentropus Hansoni = Zancle Hansoni of Stephens. This 
Species occurs in the neighbourhood of London and at Reading, and 
is undoubtedly the insect placed by Stephens, without any descrip- 
tion, under the genus Zancle, in his ‘Nomenclature.’ The males of 
this species are almost identical with those of A. niveus, but appear, 
from the specimens kindly given to me by Mr. Wormald, to be 
slightly smaller and with the upper wings somewhat less cuneated; 
but the difference is so slight that if specimens of the two species 
once become intermixed in the cabinet, it is almost impossible to
