and February (Sunley). The larval habit is very interesting. The natural 

 food of species of this group of genera appears to be dead woody fibre.

^. 10 mm. (Australian cj 6 mm.). Head pale ochreous. Thorax dark 

 iuscous. Forewings dark fuscous, with four fasciae represented principally 

 by groups of two or three white strigulae each, indistinctly connected by 

 glossy purplish-leaden striation, last supapical. Hind wings dark purplish- 

 fuscous. 



Wellington, in November (Hudson) ; one specimen. Described origin- 

 ally from one specimen, taken at Sydney, New South Wales, in November,- 

 which has hitherto remained unique. The species is a very distinct one, 

 and its identity is undoubted. Mr. Hudson has another specimen, but 

 regards the species as very rare ; it is probably semi-domestic in habits.

I HAVE lately been preparing a paper on the Australian species of Tortricina, 

 and it seemed desirable to take the opportunity to revise the New Zealand 

 species also. Considerable progress has been made in the study of the 

 group since my paper in the " Transactions of the New Zealand Institute " 

 for 1884 ; my views have been modified as to the relative value of some 

 structural characters ; the limits of the species, which are often very vari- 

 able, are now better understood, and many additional forms have been 

 discovered meanwhile. I have also corrected some unfortunate errors of 

 identification. It should be understood that many of Walker's New Zea- 

 land types are in the most deplorable condition, sometimes reduced to one 

 or two broken fragments. I therefore lately took up my whole collection 

 of the group to the British Museum, in order to have the advantage of com- 

 paring all my material with the types, and I think I have now identified 

 the whole of Walker's species of this group from Australia and New Zealand 

 with approximate certainty. 



In regard to structural characters, 1 have come to the conclusion that 

 the costal fold of the male is not of value as a generic; character, and have 

 tlierefore abandoned its use. More stress, on the other hand, has been laid 

 on certain difl^'erences in the neuration of the hindwings and on the struc- 

 ture of the palpi.
