ORDER IV. NEUROPTERA. 
63 
Moths fly abroad only in the evening and during the night, and ob- 
tain their food from the nectar of flowers. The larva is active and quick 
ln motion, and preys voraciously on the leaves of plants.

Order IV. NEUROPTERA. 
The insects of this Order ha ve four membranaceous wings, generally 
transparent with strong nervures. At the tail they have often an ap- 
pendage like pincers, but no sting. 
Genus 51. Liclllola, Dragon-fly. 
^ toutk armed with jaws, more than two : lip trifid : antenna shorter 
than the thorax ; very slender and filiform : wings extended : the tail 
of the male is furnished with a hooked forceps. 
The insects of this genus are well known ; they are remarkable for a 
long slender bodv and wings standing out at right angles. The larva* 
hav e six feet, and move with great activity in the wafer : at the mouth 
they are furnished with an articulated forceps: they are very voracious, 
at >darethe crocodiles of aquatic insects. The larvae and pupa* arc not 
v ery different; the latter have the rudiments of wings: in a fine day in 
■hine, a person standing by a pond may observe them approach the 
hank for the purpose of changing their clement. Having crawled up 
a blade of grass or bit of dry wood, the skin of the pupa grows 
Parched and splits at the upper part of the thorax. The insect issues 
forth gradually, throws oft' its slough, in a lew minutes expands its 
'vings, flutters, and then flies off. The sexual parts in the male are 
placed under the thorax; in the female at the extremity of the body. 
Sp. 1. L. quadrimaculata. (PL 7. Jig. 1.) 
Inhabits the banks of ponds, but is not common. 
Genus 55. Ephemera. 
Mouth without mandibles : palpi four, very short, and filiform : maxilla 
short, membranaceous, cylindrical, connected with the lip: antenna. 
short, and subulated : two large stemmata above the eyes : wings erect, 
the hind ones very small : seta at the tail. 
®P; 1- E. vulgata. (PI, 7. fig. 3.) 
This is the largest of the British species. In the evenings in the 
month of June it assembles in vast numbers under trees near waters, 
mid seems to divert itself for hours together, ascending and descending 
m the air as if dancing. In the neighbourhood of Luz, in Carniola, 
these insects are produced in such quantities, that when they die they 
me gathered to manure the land by the country-people, who think they 
have been unsuccessful if each does not procure twenty cart-loads of 
them for that purpose. Their larva- are the favourite food of fresh-
