PROCEEDINGS OF THE S&COND ENTOMOLOGICAL MEETING 19 
Biston in Southern India this insect was included in my book as having 
‘been once reported as damaging tea. Have you had any further ex- 
perience with it, Mr. Anstead ? 
It has not occurred again lately and I have nothing more to add. Mr. Anstead. 
It does not seem to be common in Southern India as a rule. 
We will go on to Parasa lepida. This insect, as you know, is a very Mr. Fletcher. 
ceneral feeder and occasionally occurs on tea in some numbers, but it 
does not seem to be anywhere a specific pest of tea. 
We will go on to Clama. There are numerous species, all closely 
allied and quite similar as regards the damage they do. They appear 
to be bad pests in the Northern India Tea-Districts but of less importance 
in Southern India. 
It occurs throughout the tea-gardens in Assam. The collection of Mr. Andrews. 
the bags is the simplest remedy, and this is best done after the usual 
pruning of the bushes. The pruning exposes them to view; there is a 
further advantage in collecting them at that time because the bags are 
full of eggs then. The pest is decreasing now, probably on account 
of the above measures having been adopted. j 
Does it occur in any particular localities or generally all over the Mr. Fletcher. 
Districts ? 
The pest is always bad where the bushes are not thinned out at the Mr. Andrews. 
pruning season. | 
Do you know anything about the particular species of Clania which Mr. Fletcher. 
occur as pests ? 
Of the allied species, Clana cramer? is the worst pest. Mr. Andrews. 
We will go on to the various species of Heterusia. In Southern Mr. Fletcher. 
India we have Heterusia virescens as a pest oftea, andin North-East India 
there is Heterusia magnifica and a group of doubtfully distinct species 
regarding which Mr. Antram had a paper some years ago in the Bombay 
Natural History Society’s Journal. I have not myself seen Heterusia 
on tea in India, but I have seen Heterusia cingala on tea in Ceylon. So 
far as I know the habits of all the species are very similar. One gets 
an enormous swarm of larvae in a very restricted area, often three or 
four acres in one corner of a field, where every bush is swarming with 
the larvee which do great damage; but the outbreaks are sporadic 
and rarely recur for some time after each attack as the larve are very 
heavily parasitized by Tachinid flies. 
In the Duars the caterpillars generally swarm out of the jungle and Mr. Andrews 
get into the Tea Plantations. At times the attack is very bad. Some- 
times large swarms of moths are seen in certain localities, but the con- 
sequent damage from their caterpillars is not much.
