210 Mr. E. Meyrick on the 
known, wholly endemic. Of these, 26 belong to the 
Botydide, 12 to the Scopariude, 4 to the Pterophoride, 
3 to the Crambide, and 2 to the Phycitide. The 26 
species of Butydide are referable to 8 genera, falling in 
three very distinct groups. ‘The first is represented only 
by the single species of Margarodes; this, although 
distinct, is closely allied to other species occurring in 
the islands of the South Pacific, Australia, the Malay 
Archipelago, and Ceylon, in each case confined within a 
limited range, and there can be little doubt that these 
are the little-modified descendants of one form, which 
at a date comparatively not very remote wandered, 
probably by means of its own powers of flight, which 
are considerable, over the whole of this area. The 
second consists of the genus Omiodes, containing seven 
species, an endemically developed group; the genus is 
known also from the South Pacific Islands, Malay 
Archipelago, and South America, but only to the extent 
of about eight species. The third group includes the 
oldest portion of the fauna, consisting mainly of Scopula 
(eight species), and three endemic genera allied to and 
probably derivable from Scopula; one species of Hury- 
creon and two of Mecyna. Although the three last- 
named genera are more or less represented in almost 
all regions, probability seems to be in favour of the 
origin of this part of the fauna from North America. 
Only one true Scopula occurs in Australia, and none in 
New Zealand or the South Pacific Islands. New 
Zealand, in fact, only possesses eight probably indi- 
genous species of Botydide in all, but these belong to 
the same group; they are, however, apparently of South 
American origin. 
The 12 Scopariade compare but poorly with the 
60 species of that family occurring in New Zealand, 
but I have little doubt that Mr. Blackburn  over- 
looked not a few of these obscure species, the material 
obtained being very scanty. They would probably be 
generally confined to the high mountains. It is remark- 
able that 10 out of the 12 are referable to Xeroscopa, 
hitherto principally known from New Zealand, but the 
species are more nearly allied to one another than to 
any from New Zealand. 
The Pterophoride belong to the cosmopolitan genera 
Dlatyptilia and Trichoptilus, but probably incline to
