THE SUBSTITUTE.

August 21, I found all four on, 
and feeding on Galium palustre. 
Ck. Porcellus. — Met with two 
larvse, August 4 and 18, both 
nearly full fed, on Galium veruvi. 
Both these Chcerocampce feed at 
mid-day, in the hottest sun. The 
pupa of Porcellus has two of the 
lower segments rasped like that of 
a wood-eater. 
M. Stellatarum, — July 29. I 
did catch the first and only one I 
saw. 
Bombycina. 
H. Hechis. — June 24, Great 
numbers in a damp copse close to 
our garden. 
H. Lupulinus. — June 22. 
H. Hurnuli. — July 3. 
N. Ziczac. — Took larvse, Aug. 
23, on aspeu : they were young, 
and I thought them at first Geo- 
tnelrcE : spun about September 20. 
L. Dictcea. — Took larvee, Aug. 
22, &c., on aspen : they were all 
green at first, with a red anal tu- 
bercle almost of the dimensions 
of a horn ; they all turned to a 
clayey purple after a while, and 
the tubercle diminished; they are 
long larvie in proportion to their 
width, and gradually lessen in 
bulk from the anus to the head. 
I did not recognize them lor Dic- 
tcea until I read the beautiful 
descriptions of this and Diclce- 
oicles in the ‘Intelligencer;’ Mr. 
Logan’s account especially bring- 
ing ray own larvae before my eyes. 
L. Carnelina. — May 28. Seve- 
ral at light. Found numbers of 
I the larvae on alder, oak, willow 
, and sallow, in September. 'J'hey 
■ turn up their heads over their 
I backs, in a kind of defensive pos- 
: ture, even more than the larvae of 
' Cassinea. 
[Z>. Cceruleocephala . — Larva on 
Whitethorn, June 24. Large, 
bluish white, yellow dorsal and 
lateral lines, the dorsal line be- 
coming a band on the third seg- 
ment ; black hair-tipped tubercles 
regularly disposed all over, (four 
on back and five on each side of 
each segment) ; head same colour 
as body, with two large black 
dots. Is this Cceruleocephala^ 
P. Cassinea. — November 12, 
1855. One came to light. Larvae 
almost plentiful in the beginning 
of June. 
P. Trepida. — Found the larva, 
July 27, which went into the earth 
a day or two after without eating. 
I took it at first for a Smerinthus 
larva, who had by some means 
got rid of his horn, from the ob- 
lique lateral stripes. Mr. Stain- 
ton informs me that the name 
Trepida is given to this insect 
from the larva being supposed to 
tremble when touched. I did not 
notice the peculiarity. I thought 
it a very sluggish creature. 
P. Bxicepkala. — J une 8. Larvse 
in amazing numbers. Last year 
they were almost a month later 
than they are this, so that I took 
larvse at the very end of October. 
Insects were exceedingly abun- 
dant in October, and even Novem- 
ber, last year ; but I can scarcely 
find any this autumn. 
Ps. Monacka. — July 27. Flies 
slowly at mid-day. I bred one 
specimen. 
D. Pudihunda. — May 16. Bred 
from larv® and cocoons taken last 
October. The young larva (seen 
this year) is very pale. 
O. Anliqua. — Oct. 7. Found a 
female inside a cow-shed laying 
her eggs on her cocoon. 
[N. Salicis. — Do certain yel- 
low-haired pupa skins in cocoons
