fuscous, the former with stout fuscous hairs, the latter with long

veins yellowish. Inner half of hind wing violet black, forming a 

 broad, beautiful orange band between this and the fuscous black 

 aoical soot. Abdominal segments blackish, fuscous on both dorsal 

 and ventral sides, each segment with hind margin narrowly brown. 

 Suranal plate in the genitalia of male individuals rather broad and 

 little produced in its hind margin; superior appendage, with two 

 small projections and many hairs on the end; intermediate one 

 separated at the end of a small lolie curving little upward ; inferior 

 claspcrs stout and long, suddenly becoming much more slender 

 near its end. 



Length of body 20 mm.; length of fore wing 33 mm.; length 

 of hind wing 28 mm. 



The type is a single male specimxCn in the collection of the 

 Imperial Agricultural Experiment Station at Nishigahara. The 

 specimen was captured by Mr. Murata at Nikko, on July 28ch. 



This species is closely allied to Neuronia regina, which is a 

 little larger, but the differences in the genitalia, mouth parts and 

 wing markings seem to me to warrant the specific separation of the 

 two forms.
