The Life History of Euchloe ausonides Boisd. 
Karu R. CooLipcE AND Ewat J. NEWCOMER. 
Euchloe ausonides was first described by Boisduval in 1852, 
in the Annales de la Société 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. Beutenmiiller 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, 
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. 
Edwardst says of ausonides: “Ausonides, as remarked by 
- *Bull. Am. Mus. Nat. Hist. p. 240, 1808. 
+W. 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.”
