414 SYSTEM OF INSECTS. 
by possessing the same powers of song, and produced 
by an analogous organ*: a large proportion also of both 
are endued with wonderful saltatorious powers, and their 
posterior tibiee are similarly armed; their legs in general 
also are longitudinally angular, and the head in both 
articulates with the trunk in the same manner’. In both 
Orders also, the upper organs of flight are most com- 
monly ¢egmina, but sometimes in both they are nearly 
membranous, like wings. In Centrotus F. and Acrydium 
F., the one Homopterous and the other Orthopterous, the 
front is bilobed, the eyes are small; there are only two 
stemmata between the eyes; the prothorax is conspi- 
cuous, and behind is producted into a long scutelliform 
process, under which all the parts also are analogous ; 
the abdomen articulates with the trunk in the same way, 
is similar in shape in both, and consists of short inoscu- 
lating segments. Some Fulgoride and Truxalides agree 
also in their producted front. Other analogous charac- 
ters might be named between these tribes, but these are 
sufficient to confirm M. Savigny’s opinion. ‘That the 
Neuroptera present analogies to the Lepidoptera, though 
they differ so widely from them in their metamorphosis 
and habits, is evident from the instance lately adduced 
of Ascalaphus italicus, which was described as a butterfly 
by Scopoli*; and many of the Libelludina, by their wings, 
partly transparent and partly opaque, and by the shape 
of those organs and of their bodies, imitate the Helico- 
nian butterflies: and this resemblance is much more 
striking than any that occurs between the perfect insects 
in the Newroptera and Homopterous Hemiptera. With
