The larva figured (Plate II, fig. 14) was taken in August 

 (figured August 14), 1902, at Hakodate, Oshima Province, 

 Hokkaido (Yezo), on shiro-utsiigi, also knowTi as kogome-utsugi 

 {Stephanandra flexuosa S. and Z.). Matsumura gives utsicgi 

 (Deutzia scabra Thunb.) as the food plant. This larva died, 

 but I bred two male and one female imagoes from similar larvae 

 on August 19 and 23, 1902. The larva is very common at Nikko, 

 Shimotsuke Province, Honshu, altitude 457 meters (1,500 feet) 

 on utsugi, where I have taken it in some numbers in July and 

 August. When molested it shakes its head violently from side 

 to side. 



The following description of the larva is taken from my 

 original figure : Length, 50 to 55 millimeters. Head ruddy- 

 brown with two white streaks on each lobe. Body blackish, 

 clothed dorsally and laterally with dense fascicles of ruddy- 

 brown hairs; subdorsal and midlateral lines of interrupted 

 ochraceous-gray streaks; subspiracular grayish white patches 

 on each segment between the fascicles of hair from 4 to 12; 

 spiracles white; legs brown. 



Pupa. — The pupa is inclosed in a loose, hairy cocoon. 

 Imago. — The imago varies greatly in color, as I have spec- 

 imens showing the following shades: Whitish brown, grayish 

 brown, olive-brown, purple-brown, and yellow. 



Nagano gives descriptions and figures of the imago, the pupa, 

 the larva, and the cocoon and structural details of the imago. 

 He states that he took a larva of Apha tychoona on sui-kazura
