634 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



it feeds, exactly after the fashion of some of the smaller Tmeina, 

 such as Coleophora. 



If the general remarks on the three families of Tortricina are 

 compared, it will be seen that the evidence of all points in the 

 same direction. All alike show indications of long isolation and 

 great specialisation, and are distinguished by the disproportionate 

 development of peculiar endemic groups. We have at present 

 too little knowledge of other extra-European regions to be able to 

 understand precisely the bearing of individual peculiarities, but 

 the main lines of difference are clearly defined and instructive, 

 and it may be anticipated that, when the fauna of the Malayan 

 region is made known, we shall be in a position to furnish valuable 

 evidence on the process of immigration of the Australian Micro- 

 Lepidoptera. 



It may be mentioned that according to the number of species 

 at present known, the proportion of Tortricina to Tineina is in the 

 European region 35 per cent., and in the Australasian only 16 

 per cent., or less than half the European. 



Fam. II. GKAPHOLITHIME. 



Lower median vein of hindwings pectinated with long hairs 

 above towards base; vein 2 of forewings rising from before 

 posterior third of lower margin of cell. 



The Australian and New Zealand species of the family described 

 hereafter are referred to seventeen genera, which may be 

 analytically separated as follows : 



I. Forewings with 12 veins. 



A. Veins 7 and 8 of forewings stalked. 



1. Veins 3 and 4 of hindwings from a point 1. Phricanthes. 



2. Veins 3 and 4 of hindwings stalked. 



a. Hindwings with a membranous discal 



ridge near base . . . , ..11. Epitymbia.
