Nore on EvurirHECIA ASSIMILATA.—A vigorous hop, said to be 
of the kind known as the ‘Kentish Golding,” was planted in the 
garden here about five years ago. ‘The main object in growing it 
was to obtain a sun screen for the wooden construction in which are 
housed various boxes, cages, &c., used in rearing Lepidoptera. For 
this purpose it has proved very suitable, but since 1905 moths have 
found it a convenient shelter during the summer, and the larve of 
several species feed on the foliage; among the latter is Hupithecia 
assimilata, with which species the present note is more especially 
concerned. HH. assimilata was first observed in the garden on July 
1st, 1907, when a female specimen was noticed on the paling near 
which the hop grows. In 1908 a worn female was seen on the same 
fence in early June, and in July a few larve were found on the under 
sides of the hop-leaves. These produced moths the last week in July 
and early August. Over a score of larvae were collected from the hop 
in the autumn, but the pup died during the winter. No example 
of the first flight of moths was seen this year, but on August 3rd a fine 
male was taken off the fence, and a worn one was noted on the 12th 
of the same month. Between July 20th and September 4th the 
foliage of the hop had been examined from time to time, and on each 
occasion larvze were found. These were of all sizes, some being only 
in their first or second instar, whilst others were nearly full-grown. 
These various stages of growth were not only observed on the earliest 
date mentioned, but also on the later one. Between forty and fifty 
larve altogether were secured, and all the healthy ones have pupated ; 
a rather large proportion were parasitised. One moth emerged on 
August 22nd, on which date several larvee ranging in size from newly 
hatched to half growth were seen on the hop. 
Presumably the two moths referred to as found on the paling and 
also the one that emerged in confinement were of the second genera- 
tion—that is, descendants of parents that had wintered in the pupal 
state. It seems then that the first and second generations of larvee 
have this year overlapped, and that larve of the second generation have 
been in point of time somewhat earlier than usual. Perhaps delay 
in the emergence of moths from some of the wintered pup, due 
possibly to unfavourable weather conditions, may have contributed 
to the overlapping. On the other hand, it is probable that some 
moths of the second generation may have been on the wing earlier 
than August 3rd, even about mid-July, and these have been the 
parents of the very juvenile larve found with the almost mature ones 
on July 20th.—Ricuarp Soutu; 96, Drakefield Road, Upper Tooting,
