the belly shows a paler central greenish line, and also 
those on either side, but only faintly. 
The spiracles are situated on the broad pale yellow- 
ish-white stripe; they are white, delicately outlned 
with black. 
On the 23rd the larva began to shorten, and soon 
afterwards it entered the earth.

Plate CXXIII, fig. 6. 
I owe to the kindness of Mr. A. H. Jones the supply 
of eggs which enabled me to follow out the trans- 
formations of this species, after previous failures. On 
several former occasions I had reared larve to half- 
growth, and then lost them, for want, as I supposed, of 
knowing the right food to give them; and now, after 
this more successful attempt, I am still unable to 
speak with certainty about the food, whether there is 
any one plant to which the larva is more attached 
than to any others. 
I received the eggs on August 31st, 1869; the 
larvee hatched on September 12th; they attained a 
leneth of not quite the third of an inch before hyber- 
nation, having fed on Thymus serpyllum, Achillea 
millefolium, Potentilla reptans, and Medicago lupulina. 
I kept them outdoors, and on Christmas Eve, as I was 
moving their flower-pot, a large one ten inches across 
and full of earth, to an open shed, I let it fall from a 
height of about three feet to the ground, where it 
broke to pieces, and its contents—earth and the plants 
on which the larvee had fed—lay scattered over about a 
square yard of the gravel path. Luckily I did not 
lose my temper, but—Mark Tapley-like, feeling quite 
jolly under the circumstances—I quietly got together
