A414 MODERN CLASSIFICATION OF INSECTS. 
and enclosed in a transparent silken cocoon, or elongate-ovate, conical, 
hairy, and suspended perpendicularly by a thread, or affixed by hooks 
at the posterior extremity of the body to a layer of silk on leaves. 
The rays of the wings are composed of the nerves, without any of the 
intervening membrane, which seems to be transformed into the fringe. 
In repose, the Pterophori have the habit of folding their wings so as 
to appear to consist of only a single broad ray. Réaumur has repre- 
sented the details and transformations of several of the species in his 
Mémoires, tom. i. pl. 19, 20., as has also De Geer Mém, tom. ii. pl. 4. 
f.1—11. L’Admiral and Harris have also figured the transformations 
of Pteroph. pentadactylus. 
The genus Agdistes Hubner differs from the rest in having the 
wings entire.

(OmorterRA Leach ; Hemiptera p. Linn.; Ruyneora p. Fabric.) 
Cuar. Wings four, entirely membranous and deflexed ; the anterior 
larger than the posterior, and not lapping over each other in repose. 
Body convex. 
Antenne generally very short and setigerous.

Mouth arising from the under and hinder surface of the head. 
promuscidate, the mandibles and maxilla being setaceous and en- 
closed in the labium, which forms an articulated canal. (See Vol. I.
