220 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
Some beetles appear in March but, the climatic conditions being then 
unfavourable, the grubs from the eggs laid at that time failed to develop 
under conditions in the Insectary. Control is simply a question of care 
in the regular collection of cut leaves, and their destruction by 
fire. 
Rhynchenus mangifere - the minute weevil referred to as tue 
“‘ Mango leaf-boring weevil ” in “ South Indian Insects,” p. 334, fig. 192 
it has since been ah canedk fe Dr. Marshall | Bulletin in 
Research, V, 378-379, March 1915] as Rhynchaenus (Orchestes) mangi- 
ferae. Besides the localities already given, it has since been found at 
Coimbatore and Pusa and is probably widely distributed in India, 
though overlooked. The lifehistory has already been described in my 
book, and the chief damage done is by the mining of the grubs in the 
tender leaves. In some cases considerable damage is done and this 
insect becomes a serious pest. It would be useful to try the effect of 
a nicotine spray to kill the grubs in their mines. 
Rhynchaenus mangifere was found at Pusa for the first time, and 
reared in the Insectary, in 1916. It is not common in Bihar. 
* Before we leave the subject of mango leaf pests, there is one other 
insect that might be mentioned, and that is (cophylla smaragdina 
(‘South Indian Insects,” p. 276, figs. 114, 115], the common red tree 
ant, which frequently nests in mango trees and becomes a serious nuisance 
to the fruit pluckers in the mango season. 
(Ecophylla smaragdina sometimes also spoils a number of young 
leaves by tying them together ; in such cases the growth of the young 
shoots is interfered with. 
Systematic destruction of the nests by burning them out will reduce 
their numbers considerably, but one would rather like to see the effect 
in the way of increase of caterpillar pests afterwards. 
The shoots of mango are attacked by several insects :— 
Chlumetia transversa. 
Anarsia melanoplecta. 
Alcides frenatus. 
Apsylla cistellata. 
Chlumetia transversa is widely distributed in India and we have 
examples from various localities south of the United Provinces. The 
larvee bore into the shoots and sometimes feed on the leaves and in- 
florescence. It is usually a minor pest but is reported as a bad pest 
of young grafted mangoes at Poona, boring the shoots. Occasionally 
it occurs on litchi also. The only possible control seems to be the prompt 
removal and destruction of attacked shoots.
