the Linnean Transactions.* The individual figured 
is a female ; we havo seen another specimen of the 
same sex belonging to Mr. James Wilson, lately 
received from Serampore ; and taking into account 
the prevailing character of the sexual differences 
in this group, it appears to us that there can be 
little doubt that this is the female of Phal. Altacus, 
Lucina of Drury, vol. iii. pi. 34, fig. l.t Drury's 
insect is a male ; all the specimens in this coimtry of 
Bombyx spectahilu (as far as we know) are females ; 
the size corresponds ; and the general character of 
the colour and markings is similar. The fore wings 
of Lucina are strongly falcate, those of Spectabilis 
rounded laterally ; and although this peculiarity is 
in no other instance that we are acquainted with 
so strongly marked, the considerations formerly ad- 
duced are sufficient to show r that it is not incom- 
patible with the view now taken of the supposed 
relationship of the two insects in question. The 
difference of the ascertained localities does not mili- 
tate against this view ; nearly all the Saturnise have 
a wide geographical distribution ; and it is judi- 
ciously observed by Mr. Hope, that the entomology 
of Africa (whence Drury obtained his S. lucina ) 
seems to combine the character and possess some of
