The Life History of Euchloe ausonides Boisd. 

 KARL R. COOLIDGE AND EWAL J. NEWCOMER. 



Euchloe ausonides was first described by Boisduval in 1852, 

 in the Annales de la Societe Entomologique de France. Since 

 then it has been described and figured by Edwards, Mead, 

 Holland, Wright, and others. It is closely allied to the Euro- 

 pean ausonia, and we believe the two forms will prove iden- 

 tical. Beutenmuller writes*, "The European species is double 

 brooded, and as far as I can learn the larva is also different 

 from our species." As with other North American forms of 

 Euchloe, ausonides has usually been considered monogoneutic,f 

 but in several cases which we observed last year, imagines have 

 emerged in the early summer instead of hibernating in the chry- 

 salis, thus indicating the representatives of a second brood. 



Edwardsf says of ausonides: "Ausonides, as remarked by 



*Bull. Am. Mus. Nat. Hist. p. 240, 1898. 



fW. H. Edwards (Can. Ent, XXIV, 109) writes: "I am told that 

 some collectors think that A. hyantis is the spring form of ausonides. 

 If so, it is a mistake. There is but one annual brood of ausonides. In 

 different years I have had four examples come from bred pupae ; all in 

 the month of March ; all typical ausonides."
