Canberra City, to whom I am indebted for these very interesting 
insects, writes “ This moth must be exceedingly common; its larva 
causes that strange scribble which is so conspicuous on all the 
smooth-bark Eucalyptus trees; it was long thought to be the work 
of a beetle, but, thanks to the efforts of some members of our staff, 
the moth has been bred out for the first time.” The type-specimen 
has been returned to the Canberra Museum. 
JEGERIADJE. 
ISOTHAMNIS, n. g. 
I propose to substitute this name for the genus which on p. 558 
I have called Thamnoscelis , this latter name having already been 
applied by myself in 1928 to another genus. 
HELIOZELID^E. 
MICEOPLITICA, n. g. 
I propose this name in place of Microplitis Meyr., described in 
1922 but preoccupied by Forster in Hymenoptera in 1862; I am 
indebted to' Sir Guy Marshall for kindly calling my attention to 
this oversight.
