" A distinct and well-marked species." {Murray, 1. c.) 



I found this species fairly plentiful in July at 1'suruga, on the west coast 

 of Japan. Fryer says it is common about Yokohama. My collectors obtained 

 specimens in Central China at Chang-yang and Ichang, and at Moupin, 

 Wa-ssu-kow, and Pu-tsu-fong in Western China. I also received an example 

 from Kiushiu, Southern Japan, where it was captured by a native collector.

 p. 89. Type, morpheus, Pall. 



" AntennjE short, less than half the length of costa ; club moderate, straight, elongated, blunt. 

 Palpi i)orrect, denselj- clothed with laxly set scales, almost concealing the third joint, which 

 is short, slender, and bluntly conical. Pore wing : inner margin longer than outer margin ; 

 cell less than two thirds the length of costa ; vein 12 reaching costa before the end of cell ; 

 upper discocellular short but distinct ; middle discocellular longer than lower ; vein 5 slightly 

 nearer to 4 than to 6 ; vein 3 shortly before end of cell ; vein 2 more than twice as far from 

 end of cell as from base of wing. Hind wing : outer margin even ; vein 7 well before end 

 of cell ; discoeellulars and vein 5 barely traceable ; vein 3 well before end of cell, more than 

 twice as far from 2 as from 4 ; vein 2 nearer to base of wing than to end of cell. No 

 epiphysis on fore tibia?. Hind tibia) almost naked ; in morpheus with two pairs of spurs, in 

 ornatus only with terminal pair. Abdomen reaching beyond the anal angle of hind wings."
