4 Prof. Westwood on various species of the 
till they have acquired strength to resist the ants and 
other insect enemies. The female may be seen expelling 
from her ovary these natural bodies with as much care 
as her real eggs.” 
The figures which Mr. Guilding sent to the Linnean 
Society in illustration of the history of this curious 
insect were not published, but Mr. Swainson gave a copy 
of the figure of the larva in his volume of the ‘ Cabinet 
Cyclopedia of Natural History’ (‘‘ Habits and Instincts 
of Animals,” p. 29), which represents the under side of 
the creature, with nine pairs of elongate conic setose 
appendages on each side of the body, accompanied by 
seven pairs of minute circular spiracles beneath the 
lateral appendages. Being represented from below the 
figure does not show the deeply emarginate hind part of 
the head. 
A very minute specimen of Mr. L. Guilding’s larva of 
A. Macleayanus is amongst Mr. Hope’s Neuroptera, but 
it is completely covered with gum so as not to be 
intelligibly examined. 
In my ‘ Introduction to Mod. Class. of Insects’ (vol. i1., 
p- 41) I figured, also from the collection of the Rev. F. 
W. Hope, a larva (now in the Oxford Museum), which I 
believed, and which is now proved, to be the larva of an 
Ascalaphus, and which Dr. H. Hagen considers to belong 
to the subgenus Haplogenius. The head is very flat, 
deeply emarginate behind, and the body is furnished 
with twelve setose appendages on each side. No locality 
is attached to the specimen. 
In the Bulletin of the Entomol. Soc. France, 1846, 
p-. exv., M. Guérin-Méneville stated that the larva of 
A. longicornis does not make a pitfall; that it hides 
itself under small stones, whence it seizes flies and 
other insects, on which it exclusively feeds, by means of 
its pierced mandibles, with which it sucks the fluid 
parts of its victims, and then abandons their dried 
and shrivelled-up skins. 
M. Ragonot (Ann. Soc. Ent. France, 1878, 5 ser., 
t. xil., Bull. Ent., p. exx.) announced the discovery, at 
Lardy, on a twig of grass, of two rows of eggs, at first 
supposed to be Hemipterous, but subsequently proved 
by Mr. M‘Lachlan to be those producing the larve of 
A. longicornis (see Trans. Ent. Soc. Lond., 1878, Proc., 
p- 50.
