258 STATES OF INSECTS. (Pupda.) 
this figure are the pupze of the common cheese-ma~- 
got, and many other flies. Others (Sepedon) have the 
pupa shaped like a boat. That of Syrphus Pyrastri as- 
sumes the figure of a flask ; or, according to Reaumur’s 
more accurate comparison, of a tear*. The tail of many 
of these pupae, particularly of aquatic species, is elon- 
gated into a sort of beak, either simple or forked, or 
is beset with spines variously arranged. ‘The pupa of 
Stratyomis Chameleon, and other allied species, differs 
from all the rest of this subdivision in retaining the 
exact form of the larva”; and hence constitutes an ex- 
ception to the general character of our second great 
Division. 
iii. There is much less variety in the colour of pup 
than in that of larvae. The majority of coleopterous and 
hymenopterous pupz are white, or whitish ; of lepido- 
pterous and dipterous, brown of various shades, often 
verging on black in the former and on red in the latter. 
The angular lepidopterous ones, however, are more gaily 
decorated. Some, Pontza Brassica, are of a greenish 
yellow, marked with spots of black; others are of a uni- 
form green, Apatura Iris, Pontia Cardamines ; others, 
reddish, Vanessa C. album ; others again red with black 
spots, Urania Leilus*. A still greater number shine as 
though gilded with burnished gold—either applied in 
partial streaks, Cinthia Cardui ; or covering the entire 
surface, Vanessa Urtice. It was from this gilded ap-
