198 THE ENTOMOLOGIST'S WEEKLY INTELLIGENCER. 
taken in the fens at Ranworth, as far as 
I can make them out from Dr. Hagen’s 
Monograph. I have taken numbers of 
these when out collecting, and some of 
the smaller fry have received plenty of 
abuse from me, being far more numerous 
in the fens than moths. 
Phryganea grandis. Abundant. 
P. striata. A few. 
P. varia. Abundant. 
Limnophilus pellucidus. Abundant, 
May 16 to June 24. 
L. alomarius. Abundant. 
L. vhombicus. Rare. 
L. marmoratus. Abundant. I have 
frequently beat this from sallows; it 
keeps out a long time. 
L. flavicornis. Common on sallows. 
L. allinis. Two specimens in May and 
June. 
L. elegans. Very abundant from the 
20th of iVIay to the 16th of July. 
L. bipunctatus. Common among 
Spircea uhnaria, on the sides of ditches. 
L. auricula. Common throughout the 
summer. 
L. costalis. Common. 
L. sparsus. From May to the middle 
of August, this is quite a nuisance. 
Chxtopteryx tuberculosa. Very abun- 
dant in June and July, on sallows. 
Agraylea multipunctata. This swarms 
by myriads ou the banks ol the river 
Bure, and on the sides of the peat ditches, 
along with a nearly white, minute spe- 
cies, with long antennae (much longer 
than those of Nemophofa Pilella). 
Hydroptila Vectis. Very abundant 
amongst de\il’s-bit scabious, on tire sides 
of ditches. 
I shall be happy to help any one in 
want of these insects. — W. Wintek, 
Aldebi/, near Beetles ; March 5. 
OBSERVATIONS. 
luiod-plant of Jlrpophila perla . — We 
have a colony of the laiva; u\' Brpojihilu 
perla that interests me vastly. As the 
little fellows have fixed their quarters on 
the house-side I have not got far to go 
to observe their operations. During the 
day they carefully secrete themselves in 
their sand nests; as they take care to 
make up the door-way ou entering their 
retreats, there is no chance of catching a 
glimpse of them then. The early morn- 
ing is their time of feeding ; then old and 
young are out, but soon after nine they 
retire for the day. The plant that takes 
their fancy is the Lecidea conjluens, a 
crustaceous lichen that dots over old 
walls with its cracked and weather-beaten 
patches. The shields or tubercles of this 
lichen are the chief attraction ; these 
they gnaw, removing the black crusts 
and exposing the white under-surface to 
view. Their depredations are thus readily 
seen in the morning, as the white tops 
are very consjiicuous in the sunshine. 
The Lecideas, it is well known, abound 
in tartar, none probably more* than L. 
conjluens. Soon after 9 o’clock the larvae 
withdraw to their nests for the day. It 
is stated by Westwood that the larva of 
B. perla feeds on the lichens, but as there 
are upwards of sixty Lecideas, not to speak 
of other genera, and many of these affect 
rocks and old walls, I think you will be 
interested to learn the species that feeds 
the caterpillar with us. The stone ot 
which the house is built is granite. I 
would just add a few words on the larva 
itself: it is, indeed, as you term it, “ gaily- 
coloured;” the dark livery is relieved by 
the orange-coloured stripe down the back ; 
this stripe is iuterrupted with dark spots, 
so as to give it the appearance of a chain- 
work of little hearts. The tubercles have 
each a single hair, and are black, glisten- 
ing like the head. The sides of the little 
creature tire beautifully mottled with 
slate-colour. — PhTEU Inch halo, Stortkes
