NYMPHALTNAE : THE TRIBE APATL KIDI.

after the first frost and that the leaf will fall to tlie ffronnd : the leaf does fall, but 

 not until its falling is a matter of indifterence to the caterpillar; not until the cater- 

 pillar has attached itself so firmly to tlietwig tliat neither wind nor rain can remove it. 



A Soutli American species is described by ^liiller witli similar Cfitino- 

 habits, Avliich also resemble those of our native Anaea, but the species of 

 Chlorippe, as will be seen, act very differently. The chrysalids have a 

 general resemblance to those of the Satyrinae. The insects appear to be 

 commonly single brooded and to pass the winter, either, as stated above, 

 in the caterpillar state or as butterflies. 



Some of the most showy of butterflies belong to this group, their upper 

 surface resplendent with glossy purple and blue reflections, most strikino-ly 

 exhibited by the males. Our own species have warm tints but are not ex- 

 ceptionally showy. Among the south Asiatic species there is one which 

 appears to mimic another Nymphalideous genus, Athyma, belonging to 

 the Nymphalidi, a supposition which is strengthened by finding the same 

 Athyma also mimicked by other genera and therefore presumably "pro- 

 tected." The mimicry can be of service to it, however, only when the 

 wings are expanded, as in sailing, as the mimicry is confined to the upper 

 side. Its position at rest is unknown, but if it should prove to rest with 

 wide open wings while its congeners do not, the case would be vastly 

 strengthened. 



Only one genus of the tribe occurs in eastern North America.

Lovelv, light as cloud in sky, 



Butterfly, 

 Over flowers thou fiittest free. 

 Dew and blossom food for thee, 

 Thyself a blossom, flying leaf ; 

 Who purpled thee bv rosv fingers' 



Touch so brief j* 



Was it a sylph, that thy sweet dress 



Did so impress? 

 Of morning odors moulded fine 

 Thy beauty for one day to shine ; 

 O little soiil, and thy small heart 

 Beats quickly 'neath my fingers there, 



And feels death's smart. 



Fly hence, O little soul, and be 



Bright and free ; 

 An image of that later birth. 

 When mail, the ehrysalis uf earth, 

 Like thee, a zephyr shall become, 

 And kiss in odor, dew, and lioney, 



Every bloom.
