The larva figured (Plate I, fig. 11) was taken May 21, 1901, 

 at Yoshino, Yamato Province, on evergreen oak, Japanese name, 

 aka-gashi (Quercus acuta Thunb.). A female imago emerged 

 June 8, 1901. The larva also feeds on the dwarf oaks, Japanese 

 name, kunugi {Quercus serrata Thunb.) and ko-nara {Quercus 

 glandulifera Bl.) . Graeser found the larva on Quercus mongolica 

 at Chabarowka, Amurland, eastern Siberia. 



It is an interesting fact that the larva of this species emits 

 a faint sound which resembles the feeble clucking of a hen. One 

 male and four female imagoes also emerged from larvae similar to 

 the one figured on June 7, 8, 9, 11, and 12, 1901. 



Larva. — Seitz describes the larva as pale green with yellow 

 dorsal dashes. Until the end of May, found on Quercus mongo- 

 lica, and frequently infested with Tachina. The following de- 

 scription is taken from my original figure: Length, 20 milli- 

 meters. Dark yellowish green with lateral yellow oblique 

 streaks ; dorsum on segments 5 to 11 acuminate and spined with 

 a few stiff hairs; a slender whitish longitudinal subdorsal line 

 from head to segment 5. 



Matsumura records the species from Hokkaido (Yezo) and 

 Honshu and from China, Korea, eastern Siberia (Ussuri and 

 Amurland) , and Manchuria. I have taken it from June to July 

 in Honshu and Kyushu, and Pryer records it from May to July. 



Zephyrus attilia ab. subgrisea Wileman was described from 

 two specimens taken in Yamato Province, Honshu, and as it has 

 not been previously figured, a figure of the imago is given on 

 Plate III, fig. 14. The original description is also quoted be- 

 neath for convenience of reference. It may possibly turn out to 

 be a distinct species, as the markings on the underside differ in 

 some respects from those of typical Z. attilia. The latter is 

 very common in the Bukenji Woods, near Kanagawa, Yoko- 

 hama, Honshu. 



Zephyrus attilia ab. subgrisea Wileman. 



Blackish with a faint purplish tinge; a black mark at end of cell, and 

 indications of the darker under side markings; traces of a bluish white 

 marginal line on each side of the tail. Fringes white. Under side greyish 

 white; fore wings have a brown elongate spot at end of the cell, edged with 

 white and enclosing a faint white line; a brownish, slightly oblique, post- 

 medial band, outwardly edged by a broad white band; the area beyond 

 the band is suffused with brownish and traversed by a submarginal series 

 of white-ringed blackish spots, those towards costa smaller than those 

 towards inner margin, the latter outwardly edged with orange; marginal 

 line blackish; on the hind wings the brown and the white bands are 

 similar to those on the fore wings, but the submarginal spots are less 

 clearly defined outwardly; the outer margin below vein three is orange
