Hob. — Cooma, N.S.W., (on E. viminalis; W. W. Froggatt). 



It is very curious that this species constructs such a similar 

 lerp in the earlier stages, and has the wings so exactly similar in 

 shape and venation. The colours of the larva and perfect insect, 

 however, are different. The head and thorax also are very 

 different in their form and structure. A difference in colour 

 might perhaps be due to'seasonal variation; but the differences in 

 shape of the different parts of the thorax are both distinct and 

 pronounced.
