INTRODUCTION.

The principal object of the present Catalogue has been to
give a complete list of the specimens of Neuropterous Insects
contained in the collection of the British Museum, indicating
at the same time the peculiarities of each, as regards variation
of character, locality, and the source from whence it has been
derived. With this view, the different individuals of each
species contained in the collection are indicated by the letters
a, b, c, &c, following the name of the species and its syno-
nymes, and the description, if it appeared to have been before
undescribed.

This part of the Catalogue of Neuropterous Insects has
been prepared and the new species described by Mr. Fbancis
Walker, so well known for his attention to this order of
Insects.

The continuation is in hand, and will follow as soon as it is
ipleted.

larva in form, habit and food. Rudiments of wings very percepti-
ble at the posterior angles of the wing-bearing segments. Attains
its perfect state by a double ecdysis ; after the first, the insect re-
tains the soft, silky pellicle which invests a great number of insects,
and which, in all other cases, is shed with the pupa-case. After a
feeble flight the insect settles, and in the course of a few hours di-
vests itself of the pellicle, and has then accomplished all its trans-
formations.''— Newman.
