CELASTEINA ARGIOLUS. 459 



The single-brood occurs in June and early Jul)'. In the more southern 

 parts of the States, south of 40°N. lat., on the contrary, it becomes 

 partially triple-brooded, tbe earliest and most abundant brood occur- 

 ring in March and early April, the second in June, the third from the end 

 of July until October, "but there is no general third brood" (Edwards). 

 It is unfortunate that we know nothing of the lifehistorv of the most 

 southern Nearctic form, f/ozora, of Guatemala and Mexico, which, in 

 appearance, has all the superficial characters of the subtropical Celas- 

 trinids, the discal area of wing in $ white, etc., and which is possibly 

 almost continuously-brooded. The following dates will give a clue to 

 the times of appearance in most parts of the Palamrctic area:
