I had indeed suspected this at one time, but having a number of 

 males of one form, and a number of females of the other, without 

 the corresponding sexes, taken under the same circumstances, they 

 were assumed to belong to the same species, the differences being 

 such as usually indicate the sexes in this genus, Since then the 

 other sex of each species has turned up, so that no further doubt 

 exists. The name parramattellm must be retained for the male 

 described. The female of this species is similar in all respects, but 

 generally more suffused with fuscous. 



Cliil. leptogrammellus, n. sp. 



DescribedinYul.nl., p. 178, as Chil. parramattellus, female ; 



the description need not therefore be repeated here. The male is 

 rather larger than the female, (12"- 12^"), with broader and less 

 acute fore-wings ; in other points similar. 



Taken at Sydney and Parramatta, in December, and again in 

 February and March.
