been repeatedly made, Is it distinct from 
Avellanella P We trust that those who 
have opportunities of collecting the larvar 
will, by breeding the hornbeam insect in 
plenty, set this debated point at rest. 
The food of Anguliferella is here made 
known to us as pear-leaves, and we trust 
this announcement will enable some of 
our readers at once to add that species to 
our British lists. Scutulatella had never 
before been bred, and it is therefore in- 
teresting to learn that it is a birch- 
feeder ; our own specimens of the insect 
were taken at Dartford Heath.] 
PIERIS DAPLIDICE. 
To the Editor of the * 1 Intelligencer.' 
Sir, — I have recently met with a spe- 
cimen of P. Daplidice, under circum- 
stances which led me to think that such 
“ good things” are not always so scarce 
as they are generally supposed to be. I 
was at Reading, and, as is my custom, 
seeing a bird-stuffer’s shop, I went in and 
enquired if they had any British insects 
for sale. “Only a few common butter- 
flies,” was the reply, and I was shown a 
couple of cases filled with indifferent 
specimens of Vanessa Jo, V. Atalanta, 
Argynnis Paphia and still commoner in- 
sects. But amongst the rest was a single 
white, which I at once suspected to be 
Daplidice, although I was not quite cer- 
tain. I was told that it was the “ female 
of the Orange Tip,” that it was taken 
last year on the outskirts of the town, 
and that, like the rest of the insects in 
the case, it was to be sold for fourpence ! 
The “female of the Orange Tip" turns 
out to be a genuiue Daplidice, and there 
can be no reasonable doubt that it is, as 
I was assured, a bona fide British speci- 
men. Who knows but that if the com- 
mon whites were more carefully looked 
after, their aristocratic cousin, erewhile 
of Bath, would more frequently find a 
place in our cabinets? 
I am, Sir, 
Yours very truly, 
George Keaeley.

(Concluded from p. 95.) 
I have just finished the study of a 
species, about which I wish to write to 
you specially. I will give you briefly 
the larval history of the species. The 
larva mines the leaves of Nyssa multi- 
flora in numbers that are perfectly in- 
credible. My description of the larva is 
as follows : — 
“ Subcylindrical, flattened above and 
beneath, with the segments rounded and 
projecting laterally ; a dorsal plate on the 
first segment; no legs or pro-legs, but a 
tubercle on the ventral surface of the 
twelfth ring, with a circlet of hooks. 
Head broad, circular, flattened, thin and 
retractile. Head dark brown, shield 
brownish; body very pale green, with 
dark atoms along the dorsum ; ventral 
surface with a line of double black spots. 
After the last moulting the shield becomes 
black, with a black vascular line.” 
In the mine of the larva the entire 
parenchyma of the leaf is devoured, 
leaving the upper and lower epidermis 
almost transparent. When it prepares 
for pupation the larva weaves an oval 
cocoon within the mine, and when the 
upper and lower membranes are well 
carpeted within its limits, they are cut in 
an oval form and the cocoon permitted 
to fall to the earth. The two ends of the 
cocoon are still open, and the larva 
attaches it by little cables of silk to sur- 
rounding objects on the ground, to pre- 
vent the rains of fall and spring from 
carrying it away. The pupa is thrust
