ACROPTERIS. 227 



The larvae are little known, but it is said that they resemble 

 those of the Uraniidtz^ thus justifying Sir George Hampson's 

 removal of them to that family. A typical species is, however, 

 figured here, in order to illustrate Guenee's series of families 

 of Geometry.

In this genus the fore-wings are rather longer, narrower, and 

 more pointed than in its allies, and the hind-wings have a less 

 pronounced angle, without black spots. The markings diverge 

 obliquely from the tip of the fore-wings.

This is an Indian Moth, with rather pointed fore-wings, and 

 augulated hind- wings. It expands about two inches. The wings 

 are white, the fore-wings dotted with black on the costa, and 

 there are several double brown streaks running from the base
