The larva figured (Plate III, fig. 8) was taken in July, 1901, at 

 Yoshino, Yamato Province, Honshu, on bamboo grass, sasa-gusa 

 ( ? Lophatherum elatum Zoll.) , and a female imago emerged from 

 the pupa resulting from it on August 9, 1901. 



The following descriptions are taken from my original figures. 



Larva. — Length, 30 millimeters. Yellowish green ; dark green 

 mediodorsal longitudinal line edged with yellow ; yellow subdorsal 

 longitudinal line. 



Pupa. — Green with two lines of four white spots on the 

 dorsum; suspended by the tail from food plant; it is green for 

 some time after pupation, and, as in the case of the pupa? of 

 many other Lepidoptera, turns brown before emergence (Plate 

 III, figs. 15 and 16) . Three males and two females also emerged 

 at later dates from similar larvae. There is another form of 

 the larva which, instead of being green, is a dirty grayish 

 brown with the dorsal and subdorsal lines dark. On May 12, 

 1901, I found a larva of this form at Yoshino from which an 

 imago of gotama emerged on May 31, 1901. The color of this 

 larva, however, may have been due to the fact that it was 

 preparing to pupate as the larvae of many Lepidoptera change 

 color before entering on the pupal stage. 



Nawa 26 gives a black and white figure of the larva of this 

 species, together with its transformations. Matsumura records 

 its occurrence in Honshu, Shikoku, Kyushu, and Ryukyu (Loochoo 

 Islands) . I have taken it in Honshu, Kyushu, and Shikoku, from 

 May to September. Miyajima records it from Hokkaido (Yezo) , 

 but I have never taken it there, and Matsumura does not record 

 it from that island. Rice is given as its food plant by Matsumura. 



Fruhstorfer 2T remarks : 



M. gotama, an East Asiatic collective species, which inhabits the Jap- 

 anese Islands from Hondo (Honshu) onwards, has spread from central and 

 western China to Annam and Upper Assam. 



He also gives the following subspecies, races, and forms which 

 are referable to M. gotama. 



Mycalesis gotama Moore, subspecies from Shanghai, China. 

 Mycalesis borealis Feld., subspecies from China and Japan (Nagasaki, 

 Kyushu Island) .
