brown mark, compared by Mr. Buckler to two leaves 
pointing forward, with a short stem between them, 
and preceded by two black dots; subdorsal lines

HYBERNIA AURANTIARIA. 
Plate CXXV, fig. 3. 
On November 6th, 1868, Mr. J. R. Wellman cap- 
tured three pairs of moths in copulation, and very 
kindly sent on to Mr. Buckler the eggs laid by the 
females during the next two orthreedays. The larve 
were not hatched till just about the middle of March, 
1869; were fed by me on birch; came to their full 
erowth and spun up about the middle or end of May; 
and the moths appeared November 4th to 13th. 
The egg is flattened and somewhat brick-shaped, 
but with one end more conical; the shell is stoutly 
ribbed, and reticulated, its appearance under a lens 
reminding one of coarse basket-work ; the colour is at 
first green, atterwards puce, then reddish, with a long 
central blackish spot; and lastly, just before the 
hatching, smoky. 
The newly hatched larvee are small in proportion to 
their full-grown bulk; smooth, dark brown on the 
back, with a yellowish dorsal line, and a more distinct 
yellow spiracular line; the head brown, a fine pale 
yellow transverse streak on the second segment; the 
belly dusky. After the first moult the brown dis- 
appears, and the colour throughout becomes olive- 
ereen. ‘The next moult results in a pale olive coat, 
with the middle of the back still paler; but after the 
third moult the back begins to show decidedly yellow 
again; the sides are tinged with brown, and the 
spiracular line also recovers its yellow ; and from this
