 dealhafa, and E. sideroxylon^ at Young on E. tereticornis^ and at 

 Condobolin on E. melliodora and E. rostrata. 



On further examination I find that EriojJsijlla gracilis 

 cannot be correctly referred to that genus, but must be placed in 

 Aphalara, as the stalk of the subcosta is not as long as the stalk 

 of the cubitus. The figure of the wing given in PI. xiv., fig. 11, 

 is correct, but the description of the wing in the particular men- 

 tioned is wrong.
