RHIPHEUS DASYCEPHALUS. 
PLATE XXX. 
* 
Urania Rhipheus, Var. Cramer , Godart Rhipheus Dasyce- 
phalus, Swainson , Zool. Illus. PI. 131. 
We hare copied the accompanying figures from 
Drury’s work on exotic insects, in order that they 
may be compared with those represented on Plate 
XXVIII. It will at once he perceived that they 
present numerous points of agreement, as well as 
very obvious differences, and when every considera- 
tion is taken into account, it is not easy to say 
whether they ought to be regarded as distinct spe- 
cies, or merely varieties of the same. Drury states 
that his insect was brought from China, and when 
the drawing was taken, it was in the possession of 
Captain May of Hammersmith ; in all probability, 
however, it is now lost. The antennas are described 
as black and knobbed at their extremities, and the 
hinder wings are without tails. 
On the supposition that Drury’s figures accurately 
represent the insect as it appeared when alive, the 
only connexion which it has with Urania arises 
from the similar distribution of colours and neura- 
tion of the wings ; in other respects it would be
