120 Mr. F. P. Dodd’s Notes upon some remarkable 
the whole of the material was collected by Mr. Dodd at 
Townsville, North Queensland.—E. B. PouLron.] 
Nos. 1 and 2 are from the caterpillars of Delias argen- 
thona, F. The larvee of the larger species (No. 1) push 
their way through the sides of their host, and at once 
commence to construct their cocoons in a mass, the cater- 
pillar dying and shrivelling up very quickly. The flies 
emerge through the end of the cocoon by forcing open the 
lid. The eggs of the smaller species are, I suppose, 
deposited upon the larve of the larger ere they are secure 
in the cocoons: they do not push open the lid, but gnaw 
holes to escape. 
[Colonel C. T. Bingham has kindly described the 
Braconid parasite (No. 1) as Apanteles deliadis (Appendix, 
p. 125); the Chalcidid hyperparasite (No. 2) as Microterys 
ceruleus (Appendix, p. 127). Four Bracons and three 
Chalcids bear the date Jan. 2, 1903; seven Chalcids, Jan. 
6, 1903; and nine Chalcids Jan. 9, 1903.] 
No. 3.—From Chwrocampa oldenlandix, F. [Theretra 
oldenlandiz firmata (Walk.), Rothschild and Jordan, Rev. 
Sphing., Nov. Zool., ix, suppl., p. 783.] In this (and two 
following species) only a single parasite attacks the cater- 
pillar. The larva emerges through the side of its victim, 
and spins a cocoon, like a full grain of wheat, crosswise 
upon the back, just in front of the horn. The caterpillar 
never moves from one spot, and lingers until some time 
after the parasite has flown. The caterpillar, which is 
exhibited in formalin, did not die until forty-eight hours 
after the emergence of the fly, and I found it, with the 
cocoon seemingly finished, seven days before the appearance 
of the Hymenopterous insect. 
[Col. Bingham has described this Braconid parasite as 
Microgaster basalis (Appendix, p. 125). The single speci- 
men with its oval cocoon, from which a terminal lid has 
been pushed off, bears the date Feb. 11, 1903.] 
No. 4.—Host Notodonta [Cerura] cycnoptera, Lower. 
The larva of this insect comes through the side or back of 
the caterpillar: it rears itself nearly upright and is almost 
entirely outside the aperture when it constructs the cocoon, 
which leans backwards at an angle of about forty-five 
degrees. Some twenty or twenty-four hours after, when 
the cocoon appears to be complete, the larva contrives to 
move its case from the host’s back to the leaf. Wondering 
how this transference could be effected, I examined the
