FAM. GEOMETRIDZE 25 
Geographical distribution of species. — Indo-Malayan, straggling into China. 
An interesting genus, not only as being the only extra-Australian which has preserved the 
primitive venation, but also as being the obvious parent of the following group. Shape of wings, nature 
of scaling, scheme of coloration (grey to moss-green, hindwing concolorous with forewing), commence- 
ment of shortening of cell and of rapid divergence of C of hindwing, and indeed almost all its 
characters connect it quite closely with them ; and were it not for the point of origin of SC? it would 
scarcely be separable from JNVeobalbis, and quite near Actenochroma, etc. 'The genus is fairly homogeneous 
in structure, though differing slightly in shape, and more markedly in length of antenna and in the 
cf hindtibia. In the first five species the antenna is long (nearly three-fourths the length of costa) ; in 
hyboglauca, etc. quite moderate. In farinosa, and probably Ayfpoglauca amd wsneata, the Cf hindtibia 
is undilated ; in subopalina dilated, but without terminal process; in the rest with the process, in varying 
grades of development. We have not seen sinapiaria, Poujade, and only refer it here conjecturally.
