Note on Eupithecia 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 larvce of 

 several species feed on the foliage ; among the latter is Eupithecia 

 assimilata, with which species the present note is more especially 

 concerned. E. 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 larv£e 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 pupse 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 larvee w^ere 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 

 larvte 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 larvae 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 larvi;B 

 have this year overlapped, and that larvce 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 pupa3, 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 larv® found with the almost mature ones 

 on July 20th. — Richard South ; 96, Drakefield Road, Upper Tooting,
