Descriptions 
Larva.—Mr. Carr thus describes it: —‘ About 1 inch or 
rather longer. Dark greyish below, velvety black above with, in 
some cases, a tendency towards a purplish or bluish tinge. 
Along middle of back a very faint line is sometimes to be found 
with a faint line of tiny, whitish, spots on each side; at junction 
of back and belly a number of uneven whitish yellow blotches 
forming a broken streaky line; head black; emits a black fluid 
from both ends when disturbed and frequently drops to the 
ground; rather more hairy than No. 1.’ Mr. Carr’s No. 1 
I identify as similar to my Hyblza puera, var. nigra larva. 
Pupa.—Mr. Carr describes the pupa as similar to that cof its 
companion identified as 7. puera, var. nigra. 
Moth.—¥asily distinguishable as H. constellata by its dark 
olive-green head and thorax, and by having the fore wing with 
the outer margin excised below the apex and excurved at the 
centre, whereas in the other two above described species the outer 
margin of fore wing is not excised below the apex and is evenly 
curved. The abdomen is black, with orange segmental rings 
and crimson at sides towards the extremity. Fore wing dark 
This is as far as 1 am aware, the first time this insect has been reported 
as seriously defoliating teak. The specimens were collected and the ob- 
servations made by Mr. S. Carr, F.C.H., Deputy Conservator of Forests, in 
the Rangoon Division. Unfortunately the moths sent were not actually bred 
from described larve. Three different Hyb/e@a moths have been sent to me, 
and as the descriptions of two of the larve show them to be those of H. 
puera and H. puera, var. nigra, I take the third larva present to be that of 
H. constellata. This requires further verification however,
