Cases of Long Pupal Periods among 
I^epiUopters. 
11. K. liowley, Curryville, Mo. 
In May. 1888, I received from Mr. W. 
H. Ed wards of Coalburgh, W. Va., two 
larvae ot Anthocharis genutiu which were 
feeding on pepoer grass. On the 22nd. 
of the same month both larvae pupated, 
having suspended two days before. As 
the imagoes did not appear in a reasona- 
ble length of time I communicated the 
fact to Mr. Edwards and he informed me 
they would remaiii chrysalids untill the 
next May. 1 had reared the different 
species of Rhopalocera common to the 
Mississippi Valley and considered seven 
or eight months a long pupal period for 
a Butterfly and was unprepared for a 
nuich greater length of time. 
The summer of 1889 came and went 
and still my little Genutia pupae showed 
no signs of a change of condition but en- 
teied upon the secoi.d year of their fast. 
Informing Mr. Edwards of this fact he 
then told me of the tendency in the gen- 
us Anthocharis to remain two years in 
the chrysalis state. 
The pujjae were kept through the past 
two winters in a closet, adjoining a wai m 
room and the first imago, a beautiful 
male appeared March Tth. 1890, and the 
other a female, five days later (12th.), 
after a pupal period of nearly 22 months. 
I have since learned that the Califor- 
nia species of Authocharis often remain 
two years as pupae but my informer, 
Mr. E., dees not state that he has ever 
known a Genutia pupae to go so long. 
Two years without food or drink! A 
long sleep but a glorious awakening! 
The despised and groveling caterpillar 
is metamorphosed into a thing of beauty 
and, as a gaudy Butterfly, it flits 
from flower to flow'er on wings rivaling 
the rainbow in delicacy of color, and, 
from a lowly diet of leaves, it sips 
the nectar of roses! 
Another case.— A pupal period of from 
eight to twelve months is common among 
Sphinges and Bombycids but alonger pe- 
riod is rather an uncommon occurrence, 
ta least so far as my experience and obser- 
vation in raising larvae and handling pu- 
pae go. 
On the 13th, of February, 1888, I receiv- 
ed four cocoons of CaUasomia angulifera 
from Miss E. L. Morton of Newberg, N. 
Y. These cocoons were spun in the mid- 
summer of 1887. Three of them produc- 
ed imagoes the following May but the 
fourth remained over till the 19th. of the 
next April (1889), having passed 21 or 22 
months in tlie pupal state. 
I have had chrysalids of Smerinthus 
Cl'riptogon) modeslus, Ciiheronia regalis, 
Eacle.s imperialis, Philampelus pandora 
and other moths to fail to give imagoes 
in the spring and summer, lingering even 
till early autumn before death overtook 
them, but never new one to survive till 
the next summer. 
In the April number of The Natural- 
ist on 2nd. page and 3d. column, 28th, 
line irom top of column, read "It oft'ers 
the poorest collecting inducements" in- 
stead of "It ofl"ers the best etc."
