116 CRYPTOTHELEA MACLEAYI. 
therefore, in connexion with the former species, it 
must be understood that they resemble each other 
only in their metamorphoses, which are indeed 
strikingly similar. 
Cryptothelea has the antennae pectinated through- 
out their whole extent, the pectinations gradually 
diminishing in length from the base to the apex ; 
wings broad and ample, the exterior margin of all 
of them rounded ; body slender, and the extremity 
of the abdomen not projecting beyond the line of 
the hinder wings. Female apterous, never leaving 
the puparium. 
The male of this species, named by its discoverer 
in honour of Mr. Macleay, is wholly of a black 
colour ; the female yellowish, each segment with a 
band of yellow wool-like hairs. The larva has the 
three anterior segments of the thorax and the head 
yellow with brown marks; the rest obscure and 
bearing scattered pale warts. It always carries its 
tail erect, and lives among the branches and trunks 
of old trees, frequently forming its moveable tent of 
the lichens with which they are covered. In most 
other respects the history of this insect nearly cor- 
responds to that of 0. Kirhyi.
