Each oxctvvatcd a mine or trcnoh from the outside of the root, ami in a spiral 
direction, closing it over with gnawings spun together with silk. Tlio cocoon was 
formed of the samo materials, but a Httlc more compactly at the upper cud of the 
mine, and near the surface of the earth. A few hours before the moth appeared, 
the anterior portion of the pupa was projected above ground ; it being, like its con- 
geners, furnished with rings of hooked bristles for that purpose. The perfect insect 
appeared on Sept. 10th. 
The larva being whitish and very shining, may be compared to polished ivory ; 
it is about an inch to an inch and a quarter in length, with the segments deeply divided, 
and the folds or wrinkles deeply cut. The head is orange-brown, with the mouth 
black. A plate of brownish-orange on the second segment, and marks of the same 
tint on the back of the third and fourth segments, and also on the anterior legs. 
The spiracles are dark brown, all the other parts being immaculate. A few scat- 
tered fine hairs visible with a lens. — Id., September 20th, 
Description of the larva of Leucania conigera. — On the l7th May, 1865, 1 received 
sis larvae of this species from Mr. Dorney of Brighton, which he collected for lue 
on a very wet night, while they were feeding on Triticum repens and other grasses ; 
three of them were of a bright ochreous tint, and the others an almost uniform grey 
variety. They were all cylindrical in form, tapering but very little anteriorly, and 
an inch and a half long. 
In the first mentioned the colour of the back is deep ochreous, the dorsal line 
pale sulphur-yellow, enclosed on either side By a black line, and well defined in its 
entire length. The sub-dorsal line rather broad, of equal width, and uninterruptedly 
black throughout, followed by a pale yellow line, finely edged below with black ; 
next, a stripe of pale ochreous, then another pale yellow line finely edged above with 
black, and followed by a broad stripe of deep ochreous, and broadly edged with 
black both above and below, the black spiracles being along the lower edge. Above 
the feet is a stripe of pale dull ochreous, the belly and pro-legs being slightly 
darker, the anterior pairs of black dots visible only, on the back of each segment. 
The head brownish, streaked, and mottled with black. 
The other variety is of a brownish-grey tint, with all the lines and stripes less 
distinct, but all disposed in the same order as above described ; but the yellow lines 
of the former are, in these, represented by lines of grey, and the ground colour of 
the back is brownish-grey. 
The dorsal line is grey edged with black, and the sub-dorsal is a continuous 
line of grey-brown, edged with blackish lines above and below, but interrupted 
above and nearly continuous below. The lateral lines and stripes are devoid of 
black, and delicately defined with brown edges. 
The larvaB fed until the end of May, and the moths emerged between the 8th 
and 12th of July following.— Id. 
An unusual food-plant for Sphinx Ugustri. — One day in July last I was in com- 
pany with Mr. Barrett in Woolmer Forest, Hampshire, when he found a full-gi-own 
larva of S. Ugustri feeding on holly, in a situation where this tree abounded, but far 
from any privet, Ulac, or ash.
