630 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



The Grapholitkida are represented by 49 species, less than half 

 the Tortricidce, of which in Europe they are very considerably 

 more than double. Even of this number 4 are species introduced 

 from Europe and now fully naturalised ; of the remaining 45 

 species 2 are common to Australia and New Zealand, 2 are 

 endemic to New Zealand, and the remainder are endemic to 

 Australia. The character of this fauna is strikingly peculiar and 

 of great interest, but before discussing its nature, it will be 

 necessary to make some remarks upon the internal classification 

 of the family. 



In my view the Grapholithidce, as at present known, are 

 divisible into six equivalent groups of genera, by the following 

 characters ; these groups are mostly natural subdivisions, and 

 the characters defined will be found to hold almost universally, 

 though it is not denied that exceptions may occur within the 

 limits of the group. 



A. (Pentium group.) thorax crested; antennae entire; veins 7 



and 8 of forewings separate (rarely stalked) ; veins 3 and 4 

 of hindwings from a point (rarely stalked). 



B. Eudemis group.) thorax slightly crested ; antennae entire ; 



veins 7 and 8 of forewings separate ; veins 3 and 4 of hind- 

 wings remote at origin. 



C. fPadisca group.) thorax smooth ; antennce entire ; veins 7 and 



8 of forewings separate ; veins 3 and 4 of hindwings from a 

 point. 



D. f Grapholitha 'group.) thorax smooth; antennae entire ; veins 



7 and 8 of forewings separate ; veins 3 and 4 of hindwings 

 stalked. 



E. (Palceobia group.) thorax smooth ; antennae entire ; veins 7 



and 8 of forewings stalked ; veins 3 and 4 of hindwings 

 stalked. 



F. ( ' Strepsiccros group.) thorax smooth ; antennae of male with a 



deep notch ; veins 7 and 8 of forewings separate ; veins 3 

 and 4 of hindwings stalked.
