Comparing the relative proportions of these groups in Australia, 

 New Zealand, and Europe, and adding the proportion of Tortricidce 

 as a standard of comparison, we have the following results ; and 

 although the actual number of species indicated from this region 

 will doubtless be largely increased, there is no reason to suppose 

 that the proportions will be materially changed. 



Here we have two-thirds of the Australian species correspond- 

 ing to two species in Europe, whilst the remaining third corresponds 

 to four hundred species ; whilst in New Zealand the family is 

 hardly present at all. In the only other region of which the 

 Tortricina are at all known, North America, the relative pro- 

 portions of the various groups are much the same as in Europe, 

 and groups E. and F. are not known to be represented at all. 



The indigenous Australian species of Grapholitliidcs are referable 

 to eleven genera, of which three, containing nine species, occur 

 also in Europe and North America ; the other eight, with thirty- 

 four species, are new and endemic, one only extending to New 

 Zealand. The two peculiar New Zealand species belong to two 

 endemic genera, one of which is very abnormal, the other nearly 

 allied to Australian genera. The four introduced European 

 species belong to four other genera, which are not otherwise 

 represented in the region ; there can be no doubt that they came 

 over with their food-plants, but all are now well established and 

 of common occurrence, and two at least are found in New Zealand 

 as well as in Australia. It may be remarked that one of them,
