OBSERVED IN HERTFORDSHIRE IN 1900 .

Another interesting addition to onr list is Sarothripus undulanus 
{rev ay and). Mr. Arthur Cottam writes to me with regard to it:— 
“ This little moth, which is now placed at the head of the 
Bombyces, is, I believe, often overlooked by collectors who do not 
take the micros, as it looks like a large tortrix. I am glad to be 
able to record it now for Hertfordshire. I took one in 1899 in 
Bricket Wood, I feel sure, though I overlooked it at the time, 
and only recognized what it was at the end of the season. Heeling 
doubtful, I did not record it then, but last year (1900) Mr. A. 
Piffard took one at Pelden, near Boxmoor, which he kindly gave 
to me, and Mr. Philip J. Barraud took another at Bushey Heath, 
so there is now no doubt of its being a Hertfordshire insect.” 
The lappet moth (Lasiocampa quercifolid) has been unusually 
plentiful. At St. Albans several specimens were taken on the 
street lamps by a London and North-Western Bail way employe 
who has now left the neighbourhood. 
I should like to urge upon our entomological members to devote 
more attention to the smaller moths. The neighbourhood of 
Watford is almost virgin ground so far as the micros are concerned, 
while large areas in various parts of the county remain entirely 
unexplored. 
May I also ask that other Orders of insects be studied. With 
the exception of the Lepidoptera and Coleoptera, we have practically 
no lists of our Hertfordshire insects, so that there remains much 
work yet to be done.
