THECLA. 357 
termination of the tirst median nervule, and a small anal loVic ; costal nervuve much arched 
at base ; first subcostal nervule originating some distance before the apex of the cell ; disco- 
cellular nervules concave, discoidal nervule from their point of junction ; second niediau 
nervule originating just before the end of the cell ; internal nervure very sinuous. 
"jl)!te«H(E short, not half the length of the costa of the fore wing, with a gradually formed 
elongated club. 
" Pal^n somewhat short, obliquely porrected, second joint bristly beneath, third joint naked. 
" Ei/e^ hairy. 
" Legs short, scaly." (de Nkeville, I. e.)

" Expands 1-18 to 1-40 inch. The wings are brown on the upper surface. The hind wings 
distinctly tailed. The male has one or two small orange spots near the anal angle of the 
hind wings. The female is larger and lighter in colour than the male, and has a large 
indistinct lighter patch on the fore wings, and a row of orange spots on the hind margin of 
the hind wings extending from the anal angle. The underside is brownish grey ; the fore 
wings have a distinct white line beginning on the costa at a point which is distant from the 
hind margin by a space equal to a fourth of the width of the wing. The hind wings have a 
white line running from about the middle of the costa to the inner margin, taking near the 
anal angle an upward and then downward direction, so as to give it somewhat of a W-shape. 
Along the hind margin is a row of orange spots, and near the anal angle, and filling up the 
whole distance between that point and the tail, is a patch of light blue. 
" Larva light green, with two yellowish streaks on the sides ; on each segment is a row of oblique 
lines of a darker green than the ground-colour ; on the dorsal surface, which has a dark 
streak, are some pink dots. Feeds iu June on Prumis spinosa and Crato'cfus oxyacantha." 
(Lancj, I. c.) 
Var. latior, Fixsen. "One third larger than European T. sj^ini. The ground-colour of the 
upper surface is darker and more velvety, the markings on the primaries of the female more 
distinct and broader ; the marginal band of the secondaries sharper. On the under surface 
the colour is also darker than in the type ; the white band on the primaries is more curved 
towards the inner margin, and the band on the secondaries has the W towards anal angle 
less clearly defined ; the blue on the outer margin in cell 2 is darker, and this colour extends 
upwards between two rows of black spots ; the rusty-brown band is broader and brighter." 
Fixsen states that typical T. spini occurs commonly at Pung-tung, Corea, 
and that the two specimens which he describes as var. latior are also from 
that locality. 
Staudinger (Rom. sur Lep. vi. p. 147) records both forms from Amurland, 
and says that Hertz took var. latior in North China.
