NEW CULICIDiB FROM WESTERN AUSTRALIA, ETC. 249 



The complete transformations of the summer emergence of 

 atalanta are of short duration, occupying in all about fifty days — 

 the egg state nine days ; larval state twenty-three days ; pupal 

 state seventeen days — total forty-nine days from the time the 

 egg is laid to the emergence of the imago. These are the aver- 

 age periods, which are liable to vary somewhat according to 

 temperature. 



The butterflies of the summer brood pair and produce others, 

 so that a succession of broods occur during the summer and 

 autumn, which accounts for the larvse in all stages occurring 

 from about the middle or end of June until the middle of Sep- 

 tember, and fully grown larvfe during the early part of October.
