6 Prof. Westwood on various species of the 
considered by Latreille as the larva of an Ascalaphus. 
It has the hind division of the prothoracic segment 
terminating laterally in two horny points, projecting 
laterally and scarcely wider than the hind part of the 
fore division; there are twelve fascicles of sete along 
each side of the remainder of the body, which is termi- 
nated in a semioval joint, armed at its extremity with 
eight short black horny points arranged in two groups, 
four in each. 
In the same plate Dr. Brauer has figured another 
Myrmeleon larva as that of M. (Palpares) libelluloides, 
which is represented as destitute of sete all over and 
round the body, which is terminated by two horny 
conical points, which are preceded by two still smaller 
points at the extremity of the preceding segment.* 
In the fifth volume of the same work of the Zool.- 
Botan. Society of Vienna (1855, p. 479, with plate), 
Dr. Brauer has given a careful description and figure 
of the pupa of A. macaronius, Scop. (A. hungaricus, 
Rambur), and of its cocoon, and also of the mouth of 
the imago immediately on quitting the cocoon before the 
antenne are grown to their natural length, and without 
the terminal knob by which they are subsequently 
distinguished. 
In 1871 Mr. M‘Lachlan communicated a memoir of 
‘an attempt towards a systematic Classification of the 
Family Ascalaphide,’ published in the Journal of the 
Linnean Society, Zoology, vol. xi., 1873, pp. 219—276, 
in the introductory part of which he reviewed the labours 
of his predecessors, Burmeister, Lefebvre, Rambur, 
myself, Walker, Hagen, and Brauer, both as to the 
systematic, as well as the biological, history of the 
croup and its species, and has described two larve, one 
from Saugor, Central India, given to him by Mr. F. 
Moore, and the other from the Amazon Region, possibly 
that of a species of the genus Ulula. 
In 1873 Dr. H. Hagen publishedt a memoir of con- 
* The variations in the armature of the terminal segment of the 
larvie serve to characterise, so far as hitherto known, the subgenera 
into which Myrmeleon has been divided. See Redtenbacher’s 
iibersicht d. Myrmeleoniden-larven, published in the 48th vol. of 
the Denkschriften d. Kaiserl. Akad. d. Wissenschaften of Vienna, 
1884, 4to, with seven plates, containing representations of twenty- 
five different larve of the ant-lions.
