‘*The Ccophorida are enormously developed in Australia 
(I have nearly nine hundred species), whilst those known 
from the rest of the world do not probably reach a hundred 
and fifty. This is a parallel case to the excessive develop- 
ment of the Myracea, and of such genera as Acacia. The 
Geometrid family Monoctenide are known to have about one 
hundred species in Australia, and about thirty in the rest of 
the world. The Xyloryctida, a group of Tineina, are perhaps 
not entitled to rank as a family, but only as a group of the 
Gelechiada. However, in any case they form a natural and 
distinct group, including already over one hundred species 
in Australia, whilst only one or two others have been found 
elsewhere. I could give many other cases of large 
genera, or groups of genera, mainly or entirely confined 
to Australa. 
‘‘A more peculiar case (not, I think, paralleled in other 
forms of life) is that of Crambus, which is largely developed 
throughout the whole world except Australia and the adja- 
cent islands, though Australia is eminently suited for it. 
There are two species in Australia, one an insect which 
occurs throughout most of Europe, Asia, and Africa, the 
other a Malayan and South Pacific species, so that both 
must be supposed to have immigrated; in New Zealand 
there are about thirty endemic species. 
‘**(3) New Zealand is remarkable for its poverty; only. 
about six hundred species are known, and there cannot be a 
great many more, but probably some have already become 
extinct. Most of the groups usually classed as Bombycina 
and Sphingina are altogether absent. The larger genera 
are all such as are common to all regions. Where, how- 
ever, there is a marked affinity in respect of any more 
peculiar genera, the affinity is undoubtedly with South 
America. There is also a strong archaic element; various 
small genera of one or two species, belonging to ancient 
types, probably once generally prevalent, but now every- 
where nearly extinct. Noticeable genera are— 
“« Diptychophora, fourteen species (several others in South 
‘* America, one in Australia); Scoparia, sixty species, more 
‘‘ than are known from the rest of the world, though the
