1S88.] LEPIDOPTERA OF JAPAN AND CORKA. 637 



This species is allieil tn D.fasciata, but the different coloration 

 and the shape of central fascia, which in D. approximans is much 

 attenuated towards inner margin, and has its outer edge twice 

 indented, readily separates the two species. The secondaries in both 

 sexes are also much darker than in D.fasciata. 



Several specimens, coll. Pryer (No. 238), 



Yokohama {Fryer).

Rosama macrodonta. Bull. Cist. Ent. vol. iii. p. 127 (1885).

268. Ptilodontis plusiotis. 



Ptilodontis plusiotis, Oberth. Etud. d'Entom. v. p. 65, pi. vii. 

 fig. 3 (1880). 



A female example at Gensan in July ; two males, coll. Pryer. 



The three specimens agree well each with the other, but neither 

 of them are quite hke Oberthiir's figure of his P. plusiotis ; however, 

 as my insect has been identified by Herr Banghaas as that species, 

 I am content to let it stand as such, especially as I have not seen 

 Oberthiir's type. 



Nikko, Oiwake {Pryer).

Platychasma virgo, Butl. Trans. Ent. Soc. 1881, p. 596.
