Ds METROCAMPA MARGARITATA. 
edges of the sides are produced in a ridge, from which 
proceeds a fringe of fleshy filaments of a simple kind 
as in Oatécala. The colour of the belly and of the 
filaments is pale ashy grey, and a little shining. 
There are two pairs of ventral legs only, no rudi- 
mentary ones; the first pair are rather less than the 
second pair. Theanal legs are larger than the ventral 
ones. So that the larva has altogether twelve legs. 
The segments taper a little forwards from the ninth 
to the fourth, and behind from the tenth to the 
thirteenth. The back of the twelfth bears rather 
larger tubercles than the rest, and from these slopes 
suddenly down to the anal flap when seen in profile. 
The larva is rounded when viewed on the back, and it 
is seen to be a little thicker on the thoracic segments, 
which appear tumid in comparison with those behind 
them. It thickens again a little on the ninth and 
tenth segments, both on the back and sides, and from 
these the remainder taper a little to the anal extremity, 
and below the flap are three blunt points. The 
ventral legs of the tenth segment are better developed 
than those of the ninth. 
The skin 1s puffed, but rugose along the spiracular 
region, on the third and fourth segments, and deeply 
so towards the segmental divisions on the back. The 
upper surface of the back and sides is rounded. ‘The 
tubercular warts are very small in the front dorsal 
pair, and a trifle larger in the hinder pair of each 
segment. 
The head is a little less in width than the second 
segment. 
In colour these larve vary, some being of a light 
ochreous green, others drab colour, some brownish- 
orey, others of a dark purplish-grey, more or less 
freckled with darker. There is a faint indication of a 
paler grey dorsal series of markings, most distinct at 
the hinder part of each segment, and especially on the 
eighth seement, where there is an ash-coloured trian- 
gular patch on the side pointing forwards.
