FAMILY ZYG^SNIDJE. 11 



the Castniares Boisduval, and placing the Sphingidae between 

 these and the Zygaenidai, goes a step farther in establishing the 

 group " Procrides^ consisting of those genera provided with 

 pectinated antennae. He considers the group as equivalent to 

 the Sesiares (iEgeriadaa), to the Castniares and likewise the 

 Zygasnidse. The elimination of Sesia and Thyris is an im- 

 provement upon Latreille. 



In 1832, Newman* divides the Zygasnidae into Stygiides, 

 iEgeriites and Glaucopites. 



In 1839, Dr. T. W. Harrisf like the author just quoted divides 

 the "Sphinges adscitae" Linn, into three families, i. e. Agaristi- 

 cIcb Zyg<£iiidce and Glaucopidm which last name must be a 

 synonym of Biosduval's "Procrides," since it is used in exactly 

 the same sense. 



The year after, WestwoodJ under the term Uranildm adopts a 

 provisional arrangement of Urania with Castnia and allies. He 

 rejects the name Zygsenidaj, using instead Anthroceridas 

 Westwood, since Stephens had already rejected Zygsena, "the 

 name Zygaena having been preoccupied in Ichthyology." This 

 is probably an error, since Latreille ; s name has priority over 

 Cuvier's. 



Of all the writers upon the Castniares. Klug has been the most 

 thorough. His article ' : Ueber die Lepidopteren-Gattung Syne- 

 mon,"| is a positive addition to our knowledge of these moths. 

 Besides the quite full historical account of the group, and the 

 descriptions and good figures of new species of the Australian 

 genus Synemon Doubleday, we have a mass of new facts con- 

 cerning the comparative structure of the genus above named, 

 and very precise information about the transformation of the 

 South American genus Castnia, fully confirming the obser- 

 vations of Madam Merian, which had been doubted by West- 

 wood, together with important remarks on the classification of 

 the whole group to which these two genera belong. With 

 Boisduval he agrees in throwing Urania out of the group and
