FAMILY CHARACTER. 



PALPI dilated in the middle, somewhat naked. 



ANTENNJE setaceous, simple. 



WINGS, the anterior, somewhat rounded at the base of the exterior margin. 



Tortrix Australana. PI. 17. 



SPECIFIC DESCRIPTION. 



Tortrix with greyish anterior wings, having two half bars of brown on the anterior edge, 

 with wavy marks of a dusky colour over the whole wings: posterior wings darker, more parti- 

 cularly in the male. 



Tins Tortrix is of that tribe, the larvae of which live in clusters enveloped in 

 webs, which they spread over the plant as they proceed. Our specimen we 

 found acting thus on the plant figured on the plate, spreading over it's foliage 

 a white web, under which they retired for shelter. There were a number of 

 larvae to one web, in which they continued to live together till near the time 

 of transformation, when they separated, and each individual sought a conve- 

 nient situation, and bringing several leaves together, it spun a web as shewn 

 at 2; remained fourteen days in the pupa state, and was on the wing in 

 March: the male is shewn at 4; the female at 5; and the pupa at 3. 



It inhabits swampy situations near Sidney, where also the plant is found 

 growing, which is perhaps Embothrium Speciosissimum.
