TJIECLA. 359 
Strt/mon fentoni, Butler. — " Nearly allied to S. w-alhum of Europe, but quite as large as S. qiini ; 
under surface like the latter species in tint, but with almost the pattern of S. w-alhum ; the 
discal line of the primaries, however, is more arched and continuous, that of the secondaries 
is more transverse, and therefore does not run inwards in the direction of the base ; the 
submarginal spots are more dome-shaped, of a bright orange instead of rod colour ; and there 
is a distinct submarginal white line. Expanse of wings 1 inch 5 lines. 
" Shiribetsu, Hokkaido [Yesso], August. Coll. il. Fenton." {Butler, I. c.) 
I am indebted to Mr. Janson for the loan of one of M. Fenton's original 
specimens of Butler's fentoni. It is rather larger than the examples of 
T. w-album from Yesso in Fryer's collection, but not so large as some of my 
European specimens. I cannot find any character by Avhich fentoni, Butler, 
may be separated, even as a local race, from w-album. 
Elwes (Froc. Zool. Soc. Lond. 1881, p. 886) states that AV. B. Fryer found 
T. w-album at Shanghai * and Bremer at Fekin. 
D/sfribittion. Central and South Europe, Siberia, Amurland, Japan. 
Thecla patrius. (Flate XXIX. fig. 11, d .) 
Thecla patrius, Leech, Entomologist, xxiv., Suppl. p. 58 (June 1891). 
Eesembles T. w-alhum from Europe, but in the mal^s the sexual mark is oval in shape and the 
tails are longer. The principal distinctions, however, are found in the markings of the under 
surface, where the transverse lines are more oblique ; that on the secondaries starts from 
beyond the middle of costa ; the orange band is broader, and is followed by two large velvety 
black spots ; the orange band is preceded and followed by a metallic bluish line ; the 
primaries have a pale submarginal line, which in the male merges into orange towards inner 
angle. 
Expanse 33 millim. 
A large number of specimens, including both sexes, from Pu-tsu-foug, taken 
at an elevation of about 10,000 feet in June and July. 
Thecla eximia. (Flate XXIX. figs, l d, 2, 3, var.) 
Thecla w-album, var. eximia, Fixsen, Rom. sur Lep. iii. p. 271, pi. xiii. fig. 2 CISS?). 
Thecla affinis, Staudinger, op. cit. vi. p. 148 (1892). 
Male. Fuliginous brown. Primaries have a large well-defined glandular patch agreeing in shape 
better with that of T. spini than T. w-alhum. Secondaries as in T. w-alhum, but the tails 
are longer and the reddish patch on anal lobe is brighter and larger. Fringes are white, but 
in some specimens suffused with dusky. Under surface olivaceous grey : primaries traversed 
* I have seen Fryer's Shanghai specimens in Mr. Elwes's collection and find that they are male 
examples of T. eximia, Fixsen {= affinis, Staudinger). The specimens recorded by Bremer from 
Pekin are probably also referable to that species.
