of Butterfly from the East Indies. 7 
Messrs. Kirby and Spence, indeed, make the following obser- 
vation upon the statement, that almost all butterflies suspend 
themselves, “ Except some species of Polyommatus, Latr. ( Thecla 
Argynnis, Fabr.), P. Argiolus, Corydon, See., and Hesperia Rubi 
Betulce, F. &c. Some of the larvae of the former become pupae 
within the stalk of some plant, or partly under the earth ; * those 
of the latter usually in a leaf to which the abdomen is fastened by 
various threads. These last are the rouleuses of the butterfly tribe, 
living like some moths in leaves that they have rolled up;” and re- 
ferring to the Nouv. Diet. d’Hist. Nat. 24, 499. The latter part 
only of this passage is, however, taken from that work, and refers 
to the genus Hesperia of the French authors, and not as made by 
Fabricius to include the Theclce, which are not “ rouleuses.” 
In the second place, so perfectly unique is the economy of this 
butterfly in its mode of feeding in the larva state, and precautionary 
suspension previous to assuming the pupa state, that the only ana- 
logous circumstances which I have met with throughout the whole 
of the genus Papilio, are the precautionary measures taken by the 
social larvae of the Glanville fritillary ( Melitcca Cinxia), previous to 
the setting-in of winter, in the construction of a more durable web 
than that which has served them for their ordinary tents, in which 
they remain in the caterpillar state until revived by the warmth of 
the following spring, when they again issue forth unchanged. In 
like manner the larvae of the White Admiral ( Limenitis Camilla )> 
previous to the approach of winter, (as I have been informed by 
J. Barnes, Esq. M. E. S.,) secures the leaf, in which it remains un- 
changed until the spring, from falling, by attaching it to the twig 
on which it then hangs by means of a slight web. These instances 
it will, however, be observed, are not preparatory to undergoing 
the pupa state, and this necessity for the adoption of these pre- 
cautions by the larvae is much less obvious than where this step is 
taken for the safety of the chrysalis ; since if the leaf, with the in- 
closed caterpillar, were to fall to the ground, there would be little 
difficulty in the caterpillar escaping ; but were the pomegranate to 
fall, the insect inclosed could not possibly escape destruction. I 
may be allowed to close these remarks by observing, that, in the 
various points of economy already adduced, this butterfly is cer- 
tainly one of the most interesting which has hitherto been traced 
through its different stages. 
* In the 32nd number of the Magazine of Natural History is contained a notice 
of Theda Quercus, undergoing (casually) its pupa state underground.
