AYBLAAA PUERA. 293 

warning of an impending severe attack. It will generally, I think, 
be found that the larve feed in this manner at first, if not also in 
the later stages of their existence ; the ribs in the rolled-over 
portion are never however eaten. In nurseries it will be possible 
to cut off the rolled-up edges in which the larve have pupated 
and burn them. . ; 
Points in the life history requiring further observation. 
1, The exact number of days passed in the egg stage 
in the various generations, 
2. Where the eggs are laid. Is it upon the leaves as in 
the case of Pyrausta ? 
3. Where the larve of the various generations pupate. 
Lo they pupate in the soil as well as in the 
leaves? 
4. The time spent in the moth stage. 
5. Where and in which stage is the winter passed 
through? Is it as hibernating larve or pupe in 
an earthen cocoon in the soil ? 
6. The periods in the year during which the most serious 
defoliating attacks of the pest are experienced in 
different parts of the country. {With reference to 
this point see remarks on page 311 under Py. 
rausta. | 
7. The effect of the attack upon — 
1. The flowering and seeding of the teak trees. 
2. The increment and annual rings. Are false 
rings found ? 
Parasite upon Hyblea puera. 
Tachinide. 
A fly belonging to this family, the species being as yet undeter- 
mined, was bred out of some H’. puera larve obtained by the 
writer from the Karimpoya [Teak Plantations, Nilumbur, on the 
28th August. The fly issued from the small, blunt, elliptical black 
pupa case between the 5th and 1oth September, a small lid or 
cap at one end splitting off. Further information is required on 
the life history of this parasite.
