A very distinct species, allied to C. vacuana and C. hemicosmana, 

 but readily known by the dark costal triangular patch. 



One male, taken in a gully near Sydney in October. 



Cryptoptila immersana, Walk. 



The discovery of the larva of this insect has revealed the very 

 extraordinary and startling fact that it is the female of Caccecia 

 australana, Lw. It becomes now questionable whether the costal 

 tuft of the hindwings, being confined to the female sex, is a 

 sufficient basis for generic distinction, curious as it is. I think 

 it will perhaps be better to regard the insect for the present as 

 an extreme type of Caccecia, but further knowledge of the group 

 may confirm the original separation of the genus. The specific 

 name australana, Lw. will be retained as the oldest. 



Larva elongate, cylindrical, when at rest curiously flattened 

 posteriorly, head rather large, anal segment flattened ; dark 

 bluish-grey above, yellowish-green on sides ; spots raised, rather 

 large, greenish-yellowish ; head and second segment whitish- 

 bluish, head with four large black spots on posterior margin, 

 and some black marks round mouth ; second segment with an 

 oblique linear black mark on each side ; anal segment pale 

 whitish-blue. It feeds in folded and irregularly joined leaves of 

 Hedera and Lonicera (garden ivy and honeysuckle) ; also, accord- 

 ing to Lewin, on Embothrium speciosissimum, so that it is probably 

 polyphagous. These singular larvre were found abundantly 

 towards the end of August near Parramatta, and imagos appeared 

 about the end of September. 



Tortrix trygoclana. 



I have since taken this species in abundance near Sale, Gripps- 

 land, flying very readily in somewhat swampy grass plains in 

 September. It is very variable in appearance ; the description 

 applies to a well-marked type, but the markings are very commonly
