330. Dasyophthalma. 

 1851. Westw., Gen. Diurn. Lep. 343 : Rusina, Creusa. 



• Used since in same sense by HerriclvSchaeifer, Hewitson, and Ivirby. 

 Rusina may be taken as tlie type. 



331. Debts. 



1849. [Boisd. in] Doubl., Gen. Diurn. Lep. pi. 61 : Samio. Sole 



species, and therefore type. 

 1851. Boisd. in Westw., Gen. Diurn. Lep. 358: uses it for Europa 



and eight others, including Samio. 



"Westwood designates Europa as type, but erroneously ; for the 

 plates had then been published two years, and there is no indication that 

 Boisduval, whose statement alone would have had force, intended 

 Europa for the type. No Boisduvalian species are placed in the genus 

 by Westwood, and moreover Europa is the type of Lethe, so that Samio 

 must certainly be taken as the type. If, however, Samio is generically 

 identical with Europa, then Debis falls before Lethe (q. v.). 



332. Delias. 



1816. Iliibn., Verz. 91 : Egialea (Tyche, Apriate), Pasithoe CPasi- 

 tlioe, Porsenna). 



1870. Butl., Cist. Ent. i. 34 : specifies Egialea as the type. 



See Thyca. 



333. Deloneura. 



1868. Trim., Trans. Ent. Soc. Lond. 81 : immaculata. Sole spe- 

 cies, and therefore type. 



1871. Kirb., Syn. Cat. 426: uses it in the same sense. 



334. Dercas. 



1847. Boisd. in Doubl., Gen. Diurn. Lep. 70: Verhuellii. Sole spe- 

 cies, and therefore type, as subsequently indicated by 

 Butler. 



335. Desmozona.* 



1836. Boisd., Spec, g^n., pi. 2 B., 5 C. : Mantus (Manthus), Acherois.

 species, including both of BoisduA^al's. 



The name falls before Peplia. See also Heliochlaena and Nymphi-. 

 diura.
