186 INSECTA. 
A male Coccus from Java, remarkable for its antenne, which are 
composed of about twenty-two joints, granose, and densely pilose, and 
that has two tolerably thick and almost coriaceous wings, is the type 
of the genus Monopuxesa of Leach. 
ORDER VIII. 
NEUROPTERA *. 
The Neuroptera are distinguished from the three preceding orders 
by their two upper wings, which are membranous, generally naked, 
diaphanous, and similar to the under ones in texture and properties. 
They are distinguished from the eleventh and twelfth by the number 
of these organs, as well as by their mouth, fitted for mastication or 
furnished with mandibles and true maxille, or, in other words, or- 
ganized as usual, a character which also removes this order from the 
tenth, or that of the Lepidoptera, where, besides, the four wings are 
farinaceous. The surface of these wings in the Neuroptera is finely 
reticulated, and the under ones are most commonly as large as those 
above them, but sometimes wider, and sometimes narrower and longer. 
Their maxillze and the inferior portion of their labrum or the men- 
tum are never tubular. The abdomen is destitute of a sting and 
rarely furnished with an ovipositor. 
Their antenne are usually setaceous, and composed of numerous 
joints. They have two or three simple eyes. The trunk is formed of 
three segments intimately united in a single body, distinct from the 
abdomen, and bearing the six legs; the first of these segments is 
usually very short, and in the form of a collar. The number of 
joints in the tarsi varies. The body is usually elongated, and with 
rather soft or but slightly squamous teguments; the abdomen is al- 
ways sessile. Many of these Insects are carnivorous in their first 
state and in their last. 
Some merely experience a semimetamorphosis, the rest a complete 
one; but the larve have six hooked feet, which they usually employ 
in seeking their food. 
I will divide this order into three families, which will successively 
present to us the following natural affinities : 
1. Carnivorous Insects, subject to a semimetamorphesis, with 
aquatic larve. 
* The Odonata and most of the Synistata of Fabricius.
