1872. Crotch, Cist. Ent. i. GO : refers it, as Oken did, to Linne and 

 says that the type was fixed by Cuvier in 1799 (Tubl. 

 Elem.) as brassicai. 

 Linne, however, used no such word in a generic sense, but divided 

 his genus P.apilio into sections, to which he gave plural names, Danai, 

 etc. ; these again into subsections, such as Danai fostivi, etc. ; we must 

 thorefore disregard tliem altogether in treating of genera. Cuvier used 

 it in tlie same plural form (Danai), but referred rapae as well as brassicae 

 to it. 

 1872. Scudd., Syst. Rev. 7 : specifies Plexippus as type. 



Inasmucli as the name Danaus was proposed by Latreille to sup- 

 plant his own Danaida (because preoccupied in botany, and of which 

 Plexippus was the type), and since he subsequently specified Plexippus 

 as one of the types in 1810, before any action had affected the Fabri- 

 cian Euploea, Plexippus would have to be considered the type of this 

 genus, could it stand. See Danaida. 



326. Danis.* 

 1807. Fabr., 111. Mag. vi. 286 : no species whatever indicated. 

 1815. Oken, Lehrb. i. 722: gives it as a division of Emesis, with no 

 mention of species beyond the remark " vier Arten," 

 wliich is copied from Fabricius. 

 1820. Billb., Enum. Ins. 80 : changes the name for no apparent 



reason to Hadothera (q. v.). 

 1852. "Westw., Gen. Diurn. Lep. 497 : uses it for several species, 

 commencing with Danis (Sebaj). 

 Very probably Westvvood was right, as Fabricius in several instances 

 used specific names for genera containing them. But we cannot possi- 

 bly determine this fact. If it were true, the name would fall from its 

 illegal derivation. If it were not, it would have to be dropped for want 

 of support, or possible fixity. See Damis and Thysonotis. 



327. Daptonouka.* 

 1869. Butl., Cat. Fabr. Lep. 209 : Lycimnia, Salacia. Lycimnia 

 specified as type. 

 This name falls before Melete (q. v.). 



328. Darpa. 

 1865. Moore, Proc. Zool. Soc. Lond. 781 : Hanria. Sole species, 

 and therefore type. 



329. Dasyomma.* 

 1860. Feld., Wien. Ent. Monatschr. iv. 401 : fuscum. Sole species, 

 and therefore type. 

 This name is preoccupied in Diptera (Mag. 1840).
