20 LIFE-HISTORIES OF GRACILLARIADA 
Several blotches are found on one leaf and these are usually occupied singly 
but sometimes coalesce. The larva is cylindrical with the segments rather 
strongly marked, orange with a tinge of crimson, the alimentary canal visible, 
red. When disturbed in its blotch, the larva sometimes oscillates its head and 
anterior segments rapidly. The cocoon is orange-coloured and is occasionally 
formed within the blotch. The pupal period is six to eight days, The imago 
is very sluggish in the day time. (Maavwell.) 
ACROCERCOPS PHASOSPORA, MEYR. (ante, page 147.) 
Bred in August 1914 and May 1916 at Belgaum from larve found im large 
eiongate, opaque galleries in leaves of Hugenia jambolana, both sides of the 
leaves appearing swollen. The egg is laid at one side of the mid-rib on the 
under-surface of the leaf. The young larva mines in a single gallery along the 
mid-rib towards the base tor about the length of the final blotch, then returns 
along the mid-rib for a short distance before striking across the leaf in a_ single 
gallery to the side of its blotch, and then proceeds back along the leaf parallel 
to the original gallery. The orange-coloured cocoon is found exposed.

ACROCERCOPS LYSIBATHRA, MEYR. (ante, page 152), 
Bred [at Dharwar ?] between 31st December 1915, and 4th January 1916, 
from reddish larvae mining a rather small! irregular blotch on leaves of Cordia, 
the excrement following a line close to the margin of the blotch. The cocoon 
rather large, huff-coloured. (Mazxvwell.) 
ACROCERCOPS USTULATELLA, STT. (ante, page 156). 
Bred [? in North Kanara] from larvee found in large numbers on leaves of 
Diospyros embryopteris, the larvee occupying isolated blotches on both surfaces 
of the leaf, the blotches becoming confluent in some cases. The appearance 
of the blotch is shown in the text-figure, where A represents the discoloured
