case before removal, and observed that there was a tiny 
hole, through which the larva could push its head. The 
imago emerges through a lid in the upper end. The 
caterpillar never shifts from the position it has taken up, 
along the midrib on the under-side of the leaf. Like the 
preceding and following species it is very irritable. Death 
takes place about the sixth day, generally a day or so 
before the fly emerges ; but I have found a caterpillar still 
alive after the fly had gone. One cocoon produced a 
number of minute Hymenoptera which are shown together 
with the case from which they had bored their way. Jn 
formalin several of the stung caterpillars are exhibited, 
each showing the wound caused by the full-grown 
Hymenopterous larva in its exit. 
[Colonel Bingham has described the Braconid parasite 
(No. 4) as Microgaster perelegans (Appendix, p. 126). The 
minute hyperparasites are shrivelled and indeterminable. 
Two cocoons (one attached to piece of leaf), 1 Braconid 
and 5 hyperparasites bear the date Feb. 26, 1902. 
One cocoon, 1 Braconid and 5 hyperparasites bear the 
date Feb. 27, 1902. 
One cocoon, 1 Braconid, 5 hyperparasites, and 1 cater- 
pular of Notodonta, bear the date March 2, 1902. 
Three cocoons and 1 Braconid bear March 11, 1902. 
Four of the cocoons have been opened by pushing off a 
terminal lid. The lids have been preserved with their 
respective cocoons in three examples. The cocoon on the 
leat has not been opened by a lid, but bears two minute 
apertures, one in the side and one near the end. It is 
probable that the fifteen hyperparasites emerged through 
these holes. 'Two cocoons, dated March 11, 1902, had not 
been opened from within. These two, unlike the others, 
are strongly marked by longitudinal furrows, and bear the 
appearance of a distinct cap at one end, clearly marked off 
from the rest of the cocoon by a circular ridge. They also 
differ from the other five cocoons in wanting the oblique 
flattened area towards one end which doubtless marks the 
base of attachment to the surface of a leaf.]

kingi, McLeay, of Rothschild and Jordan, Revision, p. 463.] 
This larva also places the cocoon across the back of the 
caterpillar immediately in front of the horn. One day I 
noticed three small caterpillars upon twigs: the next day 
in passing I found that each carried a case. I then took
