No. 2. ] Note on the Pest of the Teali tree. 95 



My recollection (for I unfortunately have mislaid the notes I took) 

 of the ravag-es of these caterpillars when I was in charge of the Ran- 

 goon Division^ is that they appeared in the teak plantations on or about 

 the 20th May, sometimes in almost incredible numbers. Their ravages 

 were c >nfined to certain areas, where they re-appeared year after year 

 stripping the young teak of their leaves with the rapidity almost of lo- 

 custs, and hanging in thousands by webs to the branches of the trees. 



It is quite possible that Hf/blcea puera may, like the Tortrix murinana 

 mentioned by Mr> Nisbet in paper above quoted, pupate among the dead 

 leaves on the ground, but, it' so, I should fancy few individuals could 

 survive, for a plantation attacked by these pests is a wonderful scene of 

 activity. Numbers of jungle fowl, ground thrushes [Pittx), and insectiv- 

 orous birds of all kinds crowd to the spot to feed on the cateipillars. 



'Ihe Pyrnlis, as I have alrealy said, rolls up the edge of a leaf and is 

 thus rendered less conspicous and saved from enemies. It certainly 

 occurs in far greater numbers than the Hyhlan pnern.
