MONOPHLEBUS STEBBINGI, var. MANGIFERE. 333 

soil, This statement is not understood and further observation 
is required upon this point, 
There is apparently some confusion between the damage 
done by this insect and that of ‘a flying insect’ called locally in 
the Punjab ‘Tela’ which is said to secrete a gum on the flower 
heads of the mango thus preventing fertilisation. This insect 
is said to appear earlier thanthe scale. The ‘Tela’ insect 
may be plentiful in the gardens before the ¢cale is noticed, and 
may do injury to the trees, but I think it is more than probable 
that the gum which prevents the fertilisation of the flower heads 
is the excretion of the young larval scales, which would be very 
plentiful on the trees at this period and would excrete large 
quantities of sugary secretion (see p. 137 in No. 1), 
Locality from where reported. 
Tuis insect was reported from the Shalamar mango garden 
in the Punjab in the spring of 1902, by Mr. F, Beadon Bryant, 
Conservator of Forests, Punjab. It was said to have attacked 
the garden in the previous year and to have diminished the 
outturn of fruit of the trees. 
A Monophlebus was also reported by the Manager of the 
Public Gardens in Bareilly in April. It was said to be attack- 
ing the mango trees there. Mr. Green informs me that this 
is likely to prove identical with J. stebbingt var. mangtfere, 
Green. 
Protection, 
The Conservator in forwarding the insect asked whether 
‘grease rings’ would be useful in getting rid of the pest. From 
what is known of the life history of its close relation I am of 
opinion that a good deal might be done to reduce the numbers 
of the insect by these means. A thick band of the material, 
about 15 inches deep, should be painted on the trees at about 
5 feet from the ground towards the middle to the end of March, 
depending upon whether the winter has been a dry and favour- 
able one (when the insect will develop quicker) or cold and 
wet. These bands should be kept sticky until the middle of 
May. The insects at all times walk about a great deal, but more
