Obs. — Mr. Bowerbank has kindly shown me the specimen taken 
in Messrs. Loddiges’s nursery, which I consider a female. It 
differs from Cramer’s figure, in the base, spots on the thorax and 
marks on the head being white. Beneath the hinder wings, the 
inner and marginal bands are black ; these bands are connected 
by means of narrow bands running along the nervures, thus form- 
ing cells somewhat like those on the upper surface. The expanse 
of wings is 3J inches from tip to tip.
