7 specimens (this species Mr. Stainton informs mo is a scarce insect, and that but 
little is known of it) ; Nepticula intimella and gratiosella, also new to the district. 
I made np a very fair box in three days, although very unwell at the time.

Notes on the larva of Argynnis Aglaia,. — On the 29th of June, 1867, I had the 
gratification of seeing this larva, which was most kindly presented to me by the 
Eev. Hallett Todd. 
It was found with others after a strict search amongst Viola canina, and its 
mode of feeding on the leaves of that plant was peculiar ; for, when eating, it kept 
advancing with every mouthful until it had got to the end of the leaf, and then 
quickly walked backwards to the point of commencement, and proceeded as before, 
always making a quick retrograde movement before again eating its way forward j 
and those operations were performed with such rapidity that half a lai'ge leaf 
quickly disappeared. 
When its hunger was appeased, it usually retreated below the leaves, or rested 
on the stalks of the plant. 
When nearly full fed it measured If inches in length, and tapered a little 
towards the head, and more towards the anal extremity ; it had six rows of black 
spines branched with short black hairs, viz., on each side a sub-dorsal, a lateral, 
and a sub-spiracular row, except as follows : the second, third, and fourth segments 
had but sub-dorsal and sub-spiracular rows, or four spines on each segment, the 
sub-dorsal being rather shorter than the others ; and on the second segment they 
were simple spines, leaning over the head and cui'ved slightly backwards. All 
the other segments had six spines in the order before mentioned, slanting a little 
backwards, and more so on the two last. 
The head was black, shining, and hairy. The colour of the body a dark, shining 
violet-grey, thickly marbled with velvety black, the grey not very conspicuous 
except at the segmental divisions and along the spiracular region, where it formed 
an undulating interrupted line. The slender dorsal line black, and expanded in 
width near the middle of its course thi-ough each segment, and bordered on each 
side with a stripe of bright ochreoua-yellow, which expanded in width just in 
advance of the widest part of the black central dorsal line ; the spiracles black, 
delicately margined with grey, and close below each spiracle a blotch of bright 
orange-red, connected below with a thin line of orange-ochreous, that ran beneath 
the lowest row of spines ; the belly and pro-legs blackish-brown. 
The larva continued to feed until the 9th of July, when four or five of the 
rather large leaves at the top of the plant appeared to be slightly spun together, 
forming a kind of square tent-like enclosure, within which the larva had retired. 
After the lapse of a week I broke a few of the silk threads in turning back 
part of a leaf so as to obtain a view of the occupant, and was much interested in 
seeing a very singular pupa suspended by the tail to the underside of a sloping 
leaf, its surface covered with a circular mass of silk, thickest in the centre, to 
which the anal hooks of the pupa were attached in a horizontal position, the back 
of the abdomen being so such curved round towards the leaf as to imitate the
