NEUROPTEUOUS INSECTS. 
wing, behind which is a large, pale, ferruginous 
spot, reticulated with whitish nervures 
Length one inch and seven-tenths. 
At first sight resembles L. bifasciata, Fabr., but 
is quite different ; the ultimate wing band is not 
terminal, the anal processes also are dissimilar. 
I have not seen any other specimens than the 
sexes sent me by Dr. Harris for examination. 
In some of its characters it resembles the L. 
quadrimaculata, Linn., of Europe, but that has not 
the terminal wing bands. 
8. L. leda. Wings at tip, point on the costal 
margin, and line at base, brown. 
Inhabits U. S. 
L. lydia , Drury’s Ins., Vol. II., pi. 47, fig. 1, and 
Oliv. Ency. Meth., p. 570, No. 8. 
Thorax brown, with a pale vitta ; pleura green- 
ish ; wings with a blackish point in the middle of 
the costal margin, and oblong blackish carpus ; ter- 
minal half of the anterior margins and tip fuscous ; 
a slender black line, at base, equal in length to the 
breadth of the body ; abdomen with a broad, yel- 
lowish-rufous lateral vitta ; anal segment remarka- 
bly short ; on each posterior orbit of the eyes are 
two yellow spots. 
Length about two inches. 
Yar. A. Fuscous tint on the anterior margin of 
of the wings obsolete, being only a very slight tinge 
of ferruginous. 
Drury’s figure represents this species very well, 
but the fuscous tips of the wings are generally 
broader, though sometimes altogether wanting.
