LEPIDOPTERA. — URANIID&. 369 
Acherontia Atropos, on the other hand, assumes the pupa state at the 
beginning, and becomes an imago at the end of the autumn. 
I regret that want of space prevents me from giving an abstract 
of Mr. G. Newport’s elaborate researches in the internal anatomy of 
Sphinx Convolvuli *, published in the Philos. Transactions. 
The second family Uraniipz+ comprises several very anomalous 
exotic genera, which, indeed, seem so little allied together, as to 
render the adoption of the family provisional. Latreille named them 
Hesperi-Sphinges from their apparently occupying a station between 
the Hesperia and Sphinges; indeed the typical genus Urania was 
placed by him amongst the butterflies after Hesperia: the discovery, 
however, of its preparatory states proves it to belong rather to the 
Heterocerous section of the order, its day-flying habits not being 
alone sufficient to remove it from that section; the possession also of 
ocelli, the spring and socket of the wings, and the peculiar direction 
of the nerves, equally prevent it from being united with the Diurnal 
Lepidoptera, as Dalman well observes. The splendid colours of the 
typical Uranie are, it is true, indicative of diurnal flight, and give 
them, in conjunction with their form, all the appearance of a butterfly, 
to which the tailed hind wings add considerably ; but there are other 
species (Nyctalemon Orontes and Patroclus and Sematura Lunus, &c. 
Dalman), which in their more sober colouring would be considered as 
* An instance is recorded in the Zoological Journal (No. 17.), in which several 
males of this species were attracted to a situation where the female had passed over.
