STATES OF INSECTS. (Pupa.) 245 
formed of very minute granula, the lower side being trans- 
versely sulcated. In some few instances, as in 4rctia 
Salicis, Dasychira pudibunda and. fascelina, the skin of 
the pupa is clothed with hair*: as is also that of Hes- 
peria Bixe, according to Madame Merian®. De Geer 
has described a little beetle under the name of Tenebrio 
lardarius (Latridius Latr., Corticaria Marsh.), the pupa 
of which is beset with very fine hairs, terminating in 
a spherical or oval button *. 
ii. I shall include under the same head both the figure 
or shape, and parts of pups, as the latter in most kinds 
are either the same or nearly the same as those of the 
larva, or merely incasing those of the imago, so as not to 
require that detailed notice that I judged necessary when 
treating of the parts of larve. 
With regard to ¢ncomplete pupee, nothing further can 
be said of their extremely various figure, than that it has 
a general resemblance to that of the perfect insect. The 
head, trunk, abdomen, and their respective external or- 
gans, are alike visible in both; but in the pupee, the latter, 
instead of occupying their natural situation, are all closely 
folded under the breast and abdomen: or, as in the case 
of the long ovipositors of some Ichneumons, laid along the 
back. Ina specimen of some coleopterous insect now 
before me, the following is the order of the arrangement 
of the parts: —The head is inflexed ; the mandibule are 
open; between them are seen the labium and labial palpi; 
these appear to cover and conceal the maxille, and the 
maxillary palpi extend on each side beyond them; the
