water’s edge, when it can be easily boxed. It is truly a 
water insect, as often only its head is above the surface, and 
when placed ina pill-box soon dies. These facts may be 
well known to the majority of the readers of the ‘ Ento- 
mologist, but they will possibly interest a few who are 
unacquainted with an insect whose position in our list of 
Lepidoptera has more than once been changed, and whose 
claim even to the order of Lepidoptera has been disputed.—

Lepidoptera at Wimbledon Common; June 7, 1871.—I 
have gone out insect-lunting on unfavourable days in June, 
yet scarcely remember one to equal the above-named day, 
when my evil genius led me to the Common, which, despite 
the Volunteers, is still one of the best spots for insects within 
a moderate distance of London. The wind fluctuated from 
north to east, and from east to north; and animal and vege- 
table life were alike suffering under the continued unfavour- 
able influences. On, or nearly about, this date, I have seen 
flying, pretty freely, porata, punctata, petraria, clathrata, 
maculata, strigillaria, pusaria, lactearia, and other Geometre, 
which are partial to the underwood which grows in the 
ravines or hollows. What moths, however, were about at 
this time kept themselves so closely concealed that they 
were not to be dislodged even by blows of the beating-stick ; 
and an examination of a long stretch of fence in and about 
the park produced no Macros, but only a few Tinez of the 
commonest species. Larve, as far as could be told in a 
hasty examination, were as scarce as imagos; and, unques- 
tionably, numbers have been destroyed by the chill days and 
colder nights we have had in May and June. Yponomeuta 
padella was plentiful, as usual, on the hedges, though back- 
ward in its growth. I received a renewed proof of the fact, 
that in cold weather the ravages committed by larvae upon 
the foliage of plants are far more injurious than when the 
temperature is higher. The hawthorn, in various places, 
presented a miserable appearance where these larve were 
feeding, not entirely to be explained as being the immediate 
effect of their jaws, but produced, as I conceive, secondarily, 
because the vitality of the plant languished under the 
uncongenial influence of the weather.—J. RB. S. Clifford ;
