Ilab.— Colo Vale, N.S.W. (on Acacia sp.; W. W. Froggatt). 



Dedicated to Mr. C. French, Junr., to whom I am indebted for 

 several fine species. The larvae form no lerp, but crawl about 

 freely among the tips of the foliage, and do not even seem to form

 never very numerous, but scattered all over the foliage.
