hardly possible to conjecture whence it may have originated, but 

 perhaps from the neighbourhood of Capua. 



The Tortricidce are represented in this region at present by 

 103 species, two-thirds of the Avhole Tortricina, since I have 

 altogether only about 50 native species of the other two families. 

 In Europe, on the other hand, the Tortricidce number about 145 

 species out of 680, little more than one-fifth of the whole. Of 

 the 103 species hereafter described 24 are indigenous to New 

 Zealand, and 79 to Australia, none being common to both, nor 

 are any at present known to occur elsewhere. No European 

 species of the family has yet been introduced, though the food- 

 plants of many common species have been imported ; amongst 

 the Grapholithidcr, however, there are several introduced species. 



On a general analysis of the fauna, the most striking feature 

 appears to be the development of group b., of which Acropolitis 

 may be taken as the type, since this group, distinguished by a 

 clearly-marked peculiarity of structure, is unknown elsewhere, 

 and appears to be wholly confined to the Australian region, 

 where it is represented at present by nine genera and nineteen 

 species ; the large proportion of distinct genera being very 

 noticeable. Only one of these genera extends into New Zealand, 

 where it reaches some development, being represented by at least 

 four species, much more intimately allied to one another than to 

 the single Australian species. Arranging the genera of this group 

 in a natural progression by the amount of peculiarity, we find 

 at the one end of the series forms closely approximating to Capua, 

 and at the other peculiar and abnormal types, differing widely 

 from any other group. There can be little doubt under the 

 circumstances that the whole of this group has been developed 

 in Australia from some original form closely resembling Capua, 

 and it will probably be found to be wholly confined to this region, 

 though it is of course possible that one or two forms may have 

 spread outwards to other lands. A single species of this group 

 reaching New Zealand will be sufficient to account for the
