SPHINX VESPIFORMIS. 47 



to the Erebi. Moreover, one of the Arctiidae, a native of 

 China, has the same formed palpi as Erebus and Urania ; and 

 resembles the former in thick posterior legs. However, despite 

 of all this, we will not say the author is wrong in assigning 

 it the station he has. 



From Sphinx he excludes the Egeriag and Zygsenae, placing 

 the first in the central group with Cossus, the latter in the next 

 group with Pyralis; from which he passes by llithyia and 

 Chilo to the Tineae; thence, by Halias, to Cymatophora in 

 the Noctua ; and thence, by Catocala, to Metrocampus in the 

 Geometrae. The central group is composed o{ Bomhy-ces, con- 

 nected with Papilio by Godart's Genus Barbicornis ; LaricB, 

 by Orgyia, to Nyssia in Geometra; Arctics, by Apatela in 

 this group, to Chareas in Noctua ; Lit/wsice, by Lithosia, to 

 Yponomeuta ; Notodonta;, by Cilix, to Aglossa in Pyralis ; 

 lastly, in the centre, Phalcsnce, including Attacus, Saturnia, 

 &c. 



For a further account of these groups, and also for a generic 

 character of the Genus Memythrus, a genus which he has 

 formed from Sphinx Vespiformis of Linne, we must refer our 

 readers to the work itself, a perusal of which will amply 

 repay them for the requisite time and attention. We will con- 

 elude by giving the following table of the " natural divisions to 

 which Sphinx vespiformis is referable :" —
