rf Linn. 



FAMILY CHARACTEIt. 



PALPI four, the anterior pair absolute, the posterior pair advanced forward with a ■ 

 TONGUE spiral and short. 

 ANTENNM setaceous. 



Tinea Cossuna. PI. 18. 



SPECIFIC DESCRIPTION. 



Tinea with deep purple wings, the anterior covered with large silver spots, and turned up a little 

 at the tips : posterior wings brownish, with a yellow fringe ; abdomen long and silvery. 



I found several of the larvae of this Tinea in a decayed stump of the grass 

 tree of the colonist, in which they had bored and formed long cylindrical 

 tunnels of web in divers directions, in which the larva shelters, feeding on 

 the surrounding wood, and also changes to a pupa, without any farther prepa- 

 ration than repairing to near the entrance of those tunnels. When near per- 

 fection, the pupa, by a rotative motion and the help of its serrated joints, forces 

 itself nearly out of the wood, and the moth springs forth, leaving the exuviae 

 or hull of the pupa sticking in the orifice, by which the larva had entered 

 into the wood, as figured at 4, after remaining in the pupa state near eighteen 

 days. The male moth is shown at 6 ; the female at 7 and 5 ; the larva at 1 ; 

 the pupa, taken out of its tunnel web, at 3 ; and the tunnel or passage in 

 which the larva feeds at 2. It inhabits decayed wood on the rocks south of 

 Sidney.
