nese and foreign plants. A male, which is of the interlineata 

 form, emerged in the following year on June 19, 1903. 



This larva is an example of the form of protective mimicry- 

 alluded to by Poulton under pseudaposematic colors," which he 

 defines as "an appearance which deceptively suggests something 

 unpleasant, or dangerous to an enemy." In this instance the eye- 

 like subdorsal spots probably suggest something unpleasant to 

 its enemies, as in the case of Theophila mandarina and Ophideres 

 tyrannus.^^ 



Larva. — The following description is taken from my original 

 figure: Length, about 45 millimeters. Color, shades of pinkish 

 and chocolate brown ; a broad pinkish brown mediodorsal fascia, 

 marked medially with a series of darker diamond-shaped spots; 

 head with a yellow longitudinal stripe laterad; from the center 

 of the head caudad there runs a subdorsal chocolate-brown 

 stripe, attenuated anteriorly and broadening toward the anal 

 extremity; on segment 4 a midlateral dark blue ocelluslike spot 

 on each side, ringed internally with ochraceous red and externally 

 with black; a subdorsal minute white spot on each of segments 

 4 to 11 ; a yellow stripe on each of segments 8 and 9, extending 

 from spiracles to end of prolegs; a lateral, whitish violet band 

 from segment 8 to 11 ; dorsal shield on anal segment black. 



Pupa. — Brownish black with a purple pruinescence. 



Local distribution. — I have taken this species in the following 

 localities: Honshu. Oyama, Sagami Province, May; Nikko, 

 Shimotsuke Province, May, July; Dorokawa, Yamato Province, 

 July. Kyushu. Beppu, Bungo Province, May; lida-san, Higo 

 Province, August. Leech records it from Tsuruga and Shimo- 

 noseki in Honshu, June, July. Matsumura records it from 

 Honshu, Kyushu. Hampson records it from Hokkaido (Hako- 

 date) , Kyushu, and Honshu (from Tsuruga, Nikko, Yokohama) .
