100 THE ENTOMOLOGIST. 
6 mm., and the wings 8 mm. The next moult occurred on 
July 10th, the dimensions increasing to—ovipositor 15 mm., 
wings 9 mm., and total length 34 mm. The antenne, which 
were damaged and of unequal length before, became normal 
after the second moult. It greatly appreciated being placed in 
the sun, leaning over on one side and extending the long 
jumping legs to expose as much of its body as possible. These 
sun-baths appeared necessary after each moult to enable it to 
acquire firmness and proper coloration, an operation extending 
over a period of about two days. For three days before a moult 
the nymph ceased to feed, and became sluggish and whitish in 
colour, somewhat after the style of a snake before sloughing 
its skin. 
The empty nymph skin was always eaten immediately after 
being cast, this employing the insect about an hour and a half, 
the skin of the large hind legs being eaten last. The final moult 
took place on July 31st at about 6.30 am. The imago, after 
eating the empty skin, clung for some time to the grass stems to 
allow the wings to unfold and attain their proper development. 
This specimen when taken in the hand would bite fiercely with 
the mandibles, occasionally retaining its hold until set at 
liberty. 
ADDITIONS TO THE LIST (OF KENT. APHIDIDAY 
By Frep. V. Turopap, M.A., F.E.S., Hon. F.R.H.S., &e. 
Durine the past two years I have found or identified from 
material previously collected the following Aphides, so far not 
recorded from Kent, and some of which are new to the British 
fauna. Several new species of Macrosiphum have been described 
since the previous list, and these are also included here. 
The year 1913 was noticeable for three things: first, the 
comparative paucity of the species of Aphides to be found, 
secondly, the presence of numbers of sexupare in the autumn 
months, and thirdly, the vast numbers of three or four species. 
Most abundant and harmful of all has been Aphis sorbi, which did 
untold damage to the apple crop; next in importance has been 
A. abietina, Walker, which has been most harmful to the Sitka 
and Norway spruces in Ireland and parts of the South of 
England, in many cases causing complete defoliation. This is 
one of the species which breeds entirely viviparously, no sexu- 
pare having been found, whilst parthenogenetic females occur 
right through the winter. So far no sexupare have been found 
of A. gossypii, Glover, the so-called Cotton Aphis, which is 
recorded here for the first time in Britain. Only once have I
