EUTHALTOPSIS, 



A NEW GENUS OF RIIOPALOCERA 



J. R. H. NEERVOORT VAN DE POLL. 



The insect for which the generic name of Eutlialiopsis 

 is here proposed, has been known already long since, ha- 

 ving been described by Hewitson in 1862 under the name 

 of Adolias Aetion (Ex. Butt. Ill, Adolias t. 2, figs. 6,7). — 

 Butler, in dealing with Adolias (Proc. Zool. Soc. 1868, p. 

 613), refers A. Aetion Hew. [Aetion 

 incorrectly spelt Action) to Sym- 

 phaedra with a ?. — Kirby's Catalo- 

 gue of Rhopalocera enumerates it 

 among Symphaedra without a query. 

 — Staudiuger describing (Ex. Tag- 

 falter, I, p. 152) an allied species/^ 

 or local form viz. Plateni Staud. , 

 places Aetion in Euthalia. — An 

 examination, however, of the neu- 

 ration of the forewiug shows at a 

 glance that Aetion cannot find its 

 place neither in Euthalia (Adolias) 

 nor in Symphaedra, differing from 

 both as well as from the other al- 

 lied genera by having only four 

 instead of five subcostal-nervules. — The position of these 

 nervules is no doubt better shown by the accompanying 

 figure than by any description. — Hewitson's final remark
