OBSERVED IN HERTFORD SHIRE IN 1901 . 
169 
Mr. Arthur Cottarn, of Elderscroft, Watford, is, as usual, able to 
report the occurrence of some interesting species. Besides those 
already mentioned, Mr. Cottarn secured in Whippendell on July 6th 
a specimen of Macraria liturata , an insect which has only been 
recorded from two other Hertfordshire localities—Sandridge and 
Haileyhury. On the same occasion he caught a fine Bowrmia 
roboraria , the great oak beauty, the only previous record for this 
insect being Haileybury, where three have been taken at light. 
He also beat out three Metroeampa margaritaria , but only secured 
one, the others fiying straight up in the air and settling on the 
tops of the trees. On the evening of the same day Abraxas ulmata 
and Arena flexula came to light, and on the 20th two specimens 
of Cosmia pyrolina. 
Mr. Philip J. Barraud, of Bushey Heath, has been good enough 
to send to me a list of the species which he captured at “light” at 
Bushey Heath in 1901, and this I give as an appendix at the end 
of my Report. He tells me that during the year he noted about 
240 different species of Lepidoptera within a short distance of his 
residence. The majority of his captures were made with a light- 
trap, which he constructed to fit one of the upper windows of the 
house. Of these, in addition to Spilodes palealis , the species 
which he had added to our county list, the most remarkable are 
the light-feathered rustic ( Agrotis cinerea ), the true-lover’s knot 
(A. porphyrea ), the monk’s-hood ( Plusia moneta ), of which four 
came to light and four were taken at dusk, the lunar-spotted 
pinion ( Calymnia pyralina ), which was fairly plentiful, and a brown 
aberration of Spilosoma menthastri, the white ermine. Mr. Barraud 
did not find sallow-bloom or ivy to yield anything of note, nor, 
judging from the list which he has sent me, was he more successful 
with “ sugar.” 
Mr. A. T. Goodson, of Tring, has bred Notodonta dictcea from 
larvae taken from the poplar-trees at the Tring Museum. Asphalia 
diluta was captured at sugar in Wick Wood, Phorodesma pustulata, 
Hufn. (P. bajularia , SchifL), being taken in the same locality, but 
on the outskirts of the wood, where Mr. Goodson disturbed it 
when beating for larvae in mid-afternoon on July 7th. Hear Wick 
Wood, too, Eueosmia undulata was captured, flying about a foot 
from the ground, a second specimen being taken by Mr. W. H. 
Smith, of Tring, in much the same manner, flying in the daytime 
in Brown’s Lane. Mr. Goodson was also fortunate enough to find 
the larvae of Pygeera pigra on sallow in Brown’s Lane. 
Amongst the insects captured during the year by Mr. W. C. 
Boyd, of The Grange, Waltham Cross, who is an enthusiastic 
worker among the micros, may be mentioned the pretty little 
Crambus pinellus , which occurred twice. In Broxbourne Woods 
he secured Grapholitha nigromaculana , Pcedisca solandriana , and 
Glelechia bifractella , three species which previously have only been 
recorded from Sandridge; the last-named he describes as being 
common. Mr. Boyd also reports the occurrence of a worn specimen 
of Plusia moneta.
