appeared before the females, I had never heard it called in 

 question : since then circumstances have prevented me from 

 rearing many larvae ; but in the few broods of which 1 have 

 been able to take note the facts confirm Mr. Greene's view, 

 that in the majority of cases the female is the first to appear. 

 I give the dates of the emergence of five broods — two of 

 Lithosia caniola, one of Orgyia fascelina, one of Amphydasis 

 prodromaria, one of Dianthoecia capsophila : in all, except 

 capsophila, the female appeared first. I trust some of your 

 correspondents who have had a wider experience in rearing 

 Lepidoptera will furnish notes on the point, as no rule can 

 be laid down from isolated cases.
