PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 79 
Eurybrachys ferruginea occurs in small numbers on EHrythrina but 
is not a pest. 
Dactylopius citri on Erythrina is chiefly important in coffee when 
Erythrina roots afford shelter to colonies of this scale. 
In the Darjiling District a Jassid bug is bad on Hrythrina. It is Mr. Andrews. 
apparently an Hmpoasca but different from the species found on tea. 
Eriochiton theae is also found on Erythrina in the Duars. 
ALBIZZIA. 
The insect pests of the species of Albizzia are likely to come to pro- Mr, Fletcher. 
minence in India as these plants become more used for green-manure. 
On the leaves we get Terias silhetana and T. hecabe, both of which 
we have already dealt with under dhaincha. 
Boring in the stems of Albizzia lebbek we have Xystrocera globosa 
{‘‘ South Indian Insects,” p. 321, fig. 174]. It is common in India but 
not yet noted as a pest, so far as our experience is concerned, but it has 
been recorded as a serious pest of Albizzia lebbek when grown as shade- 
trees in Egypt, so that it is a species to keep our eyes on in India. 
At Coimbatore I have also found.a weevil grub boring the seeds of 
A. lebbek inside the pods, but I cannot say any more about it. 
We now come to 
YNDIGO 
under which we will take the Natal plant (Indigofera arrecta) and the 
Bengal Indigo (I. swmatrana). 
The seedlings are attacked by— 
Chrotogonus. 
Brachytrypes portentosus (achatinus). 
Laphygma exigua. 
Agrotis ypsilon. 
Chrotogonus in Bihar is chiefly a pest of sumatrana seedlings about 
March, and sometimes.does so much damage that resowing is necessary. 
It may be controlled by bagnets. 
In Jalgaon (Khandesh) young indigo plants are attacked by Chroto- Mr. Jhaveri.

Brachytrypes portentosus (achatinus) is also chiefly a pest of swma- Mr. Fletcher. 
trana seedlings, the crickets cutting the young plants and dragging them 
into their burrows. This cricket is often reported as a pest but is pro- 
bably not a very serious one on the whole. Irrigation, where possible, 
is the only successful method of control; this drives out the crickets 
which are then destroyed by birds and other enemies.
