LEPIDOPTERA. 
his peculiar theories, he gave it as a subgenus of the genus Urania, which name he 
changed to Leilus, (considering its type to be the Papilio Leilus of Linnaeus,) on the 
ground that the name Urania had been employed in Botany, which is certainly the 
case ; but as the genus of plants ought to retain its 'previous name Ravenala, the name 
of Urania is not inapplicable to a genus of Lepidoptera. But Leptocircus ought 
clearly not to be regarded as belonging to the same group as Leilus, Orontes, and 
Rhipheus, together with Patroclus, Lunus, and Empedocles, which decidedly belong 
thereto, although omitted by Mr. Swainson. The veins of the wings of Leptocircus are 
decidedly Papilionideous, and have no resemblance whatever to those of Urania. There 
is it is true some analogy in the form of the posterior wings, but, I presume, no real 
relation can be supported on such a character, and I can discover no other to give it a 
relation either with Urania, or Erycina. In the male of this insect, the pale band 
crossing the wings is of a greenish white, but in the female it is transparent white in 
the anterior, and white in the posterior wings. 
The species was described by Fabricius from a specimen in the collection of Sir 
J. Banks. It is become sufficiently common.
