the discoidal cell, and a rounded one towards the apex of the wing ; the costa, apical margin, and a patch at the 
extremity of the discoidal cell, are black. 
This species is extremely rare, only one specimen being decidedly known to have been taken in this country 
by Francillon, from whose collection it was purchased by Mr. Haworth. At the sale of the collection of the last- 
mentioned Entomologist, it and numerous other very rare British Sphingide, were purchased by Mr. Warburton. 
It occurs plentifully in Germany and the north of Italy.

This rare species measures nearly an inch in the expanse of its wings. It is of a brownish black colour; the 
head has a white patch in front, and the collar is yellowish, as are also the palpi, of which the tips are brownish ; 
the antenne have the middle part yellowish above, but ferruginous beneath in the female, but darker in the male : 
the thorax has a lateral line, and a slender transverse one near the base of the abdomen, yellow; the abdomen 
(which is not so slender as in many of the species) has six or seven yellow dorsal fascie in the male, but 
only five or six in the female; the fan tail is small and black, but marked with a few yellow hairs, forming two 
lines. The wings are hyaline, with the margins and discoidal spot orange-brown ; the posterior margin and apex 
of the upper wings orange ; the tibiew and tarsi are orange, with a black spot near the tip of the former. In 
wasted specimens the colours become paler, which agree with the Fabrician and other descriptions. 
This species has generally been found in various parts of the south of England, Hastings, Devonshire, 
Teignmouth, and in the Isle of Wight by Mr. Weaver, (who informs me that he took several near Freshwater 
Gate, hovering over a yellow flower ;) near Bristol, at Creak, on the coast of Norfolk.
