to rose-colour, tlie red bands margined with wliite 
anteriorly, and there is a broad grejnsli stripe down 
the back divided in the middle by a black line. 
The antennsB are whitish, a.s well as the under side 
of the body, the latter haring two black spots in 
the middle of the belly. The expansion of the 
wings is about four inches and a half. 
The caterpillar is very variable in colour and 
markings. It is most commonly of a bright green, 
(as represented on PI. vi. fig. 2.), with black or 
brown spots on the back, and oblique yellow stripes 
on the sides ; the latter, however, are sometimes 
black, and examples are occasionally found in which 
the whole body is bron-n. The stigmata are usually 
of some colour contrasting with the rest of the 
body ; most commonly they are hlack or pink. It 
feeds on the indigenous species of convolvulus, 
particularly C. Septum, It generally assumes the 
pupa state about the end of July, the moth appear- 
ing in September ; but if the larva be not fuQ 
gro\vn till a later period, the perfect insect is not 
disclosed till the ensuing May or Jime. 
The Unicom or Bindweed Hawk-moth, termed 
by a French naturalist the Ox-homed Sphinx, on 
account of the thickness and rigidity of its antennm, 
is by no (means an insect of common occurrence in 
Britain, but it seems to be distributed over the 
whole island. It has been found in the northern 
extremity of Scotland, as w'ell as in several of the 
southern counties, and numerous localities have 
been cited for it in most parts of England. Godart
