caterpillars eat the bark under cover of a silken gallery, which generally 
leads into a tunnel excavated into the tree, usually im the angle of a 
branch. The caterpillars can sometimes be hooked out with a piece of 
wire, or their galleries may be syringed out. 
Arbela is very common in orange trees at Nagpur. The moths emerge. 
in May and June. 
The flowers of Citrus are attacked by a few insects :— 
Prays citrt. 
Oxycetonia albopunctata. 
Colasposoma semicostatum. 
Prays citri I told you about the other day. It occurs in India,. 
probably throughout the Plains, having been found in Coorg and at 
Pusa. In the South of Europe the larva does serious damage by des- 
troying the flowers of orange, and it is quite possible that it may do 
damage in India also, although it has not actually been noticed. It 
is an insect that you might look out for when Citrus trees are in flower. 
Oxycetonia albopunctata has been found eating lemon flowers at Pusa,. 
but is not a pest as far as we know. 
Colasposoma semicostatum 1s reported to injure orange flowers in. 
Assam. 
A beetle attacks the flowers in Assam but I do not know what it is. 
The next group of insects comprises those attacking Citrus fruits :— 
Ophideres fullonica. 
Virachola isocrates. 
Heliothis obsoleta. 
Anthomyiad Fly. 
Chetodacus ferrugineus. : 
4 caudatus. 
ap diversus. 
Ophideres fullonica is sometimes a serious pest of pomelo and’ is: 
especially interesting because it is one of the few cases in which damage. 
is done directly by an adult Lepidopterous insect. The tip of the tongue. 
of the moth is provided with an armament of sharp teeth with which 
it penetrates the rind of the fruits and sucks them so that they are spoilt. 
The structure of the tongue is figured in Entomological Note 64, Bulletin 
59. At Tardeo, in Bombay, a loss of a quarter to a third of the pomelo 
crop has been reported as due to this moth, the attacked fruit falling 
from the trees. This moth is also well known to attack fruit in Australia 
and South Africa. Control measures are suggested in the Entomological 
Note just quoted. It is hardly possible to check the increase of the 
moths as the larve feed on Quisqualis and wild creepers.
