noides Leech (88 a, b), from West China 



Wings darker brown, not yellowish grey. Hindwing beneath darker, with the spots much 

 similis. more distinct. A. similis Leech (88 b). Likewise from West China.

Leech (88 b) is a $ in which the spots of the hindwing are white, not reddish yellow. 



Stigma black, with a white central hne. Base of eosta of forewing of a more pronounced 

 reddish yellow. Underside of hindwing without silver spots and without black margin . . 6. 



brahma. 6. Expanse 33 — 35 mm. A. brahma Moore. North- West Himalayas. 



crateis. „ 42—47 mm. A, crateis Leech (88 b, c). West China. 



ochracea. 7. Size smaller. Forewing pointed, margin dark yellow beneath. A. ochracea Brem. (88 c). 



rikiwhina. The var. rikuchina Bflr. is a blackish form in which the wings have a broad black border, 



while the rest of the surface is much darkened. The $$ are not more black and have 2 

 yellow dots in the cell and a subterminal row of much reduced pale spots. The underside 

 of the wings is blackish, dusted with yellow scales. The veins are always more black than 

 the ground. Amur, Corea, Japan. 



36. Genus: Erynnis Schrank. 



Antennae less than half the length of the costal margin; club with distinct thin point. Stigma 

 of forewing ((^) completely covering the angle before vein 2. This genus contains only a single, very 

 variable Palearctic species, the Japanese form being in our opinion hardly maintainable as a distinct species. 



comma. E. comma L. (88 e). Forewing brown with pale costal margin and pale dots or spots, which are 



arranged as follows: 3 apical dots, 2 more very close to the margin between veins 2 and 6, separate from 

 an oblique row of 3 more dots between veins 4 and 1. Hindwing with a dot at the base of the cell and 

 a continuous row of 4 — 5 pale spots. Underside of hindwing reddish grey; 3 spots at the base below the 

 cell and 6 more in a semicircle. $ with the same dots and spots, which however are much darker. 

 Throughout Europe and Asia to the Amur; in July and August, abundant everywhere. 



A number of aberrations have been named; Tutt, for instance, called very light specimens ab. 

 clara, dark ones with ochreous spots ab. suffusa, others with only a dark edge ab. intermedia, dark speci- 

 mens with reduced spots ab. extrevia, with confluent spots on th underside ab. conflua, with whitish spots 

 pallidipuncta, etc. etc. We consider the following insects local forms of the type described above, with 

 the exception of florinda, which might be regarded as a distinct species, as will be seen from the description : 



catena. — catena Stgr. (88 d). Underside of hindwing green, with the spots more whitish and edged with black. 



2:)allida. North Europe, Lapland, Sweden, summit of the Alps. — pallida Stgr. Paler, especially beneath. Some 



mixta, of the veins of the hindwing white. Sicily, Greece, Syria, Taurus, Pontus, and Kurdistan. — mixta Alpli. 

 Wings darker. Underside of the hindwing with the spots greenish, white and glossj^ Tian-Shan, Fergana, 



dimila. Pamir. — dimila Moore (88 d). Very close to mixta, from which it differs in the very dark hindwing 

 and also in the spots of the hindwing beneath being white, not emarginate and not bordered with black. 



alpina. North- Western Himalayas. Ta-tsien-lu. ■ — alpina Batli. Wings of the $ black, slightly reddish. The 

 spots of true comma are present in aljyina, but small and yellowish: 3 apical dots, a double spot in the 

 cell and 5 others in an oblique row between the branches of the veins, the upper 2 of them separated 

 from the lower 3 and placed much out of line with them. Hindwing with a central dot, and 3 others in 

 a transverse row, hardly visible. Underside of forewing dark greenish grey at the costa, apex and outer 

 margin; centre of wing very black. Hindwing very dark grey-green, all the spots white bordered with 

 black. This form is similar to catena, but differs much in its darker colouring, which approaches black. 

 From the high Alps. 



florinda. E. florinda Btlr. {= micado Mab.) (88 d). Wings broadly bordered with black in both sexes. 



Hindwing beneath dull yellow or greenish, with small pale spots. The spots of cellules 4 — 6 hardly out 

 of hne with the others. This character, which it has in common with sylvanus, makes us hesitate to treat 

 florinda as a variety of comma. The very dark $ has only 3 spots an the underside of the hindwing, one 

 between 6 and 7 and two between 2 and 4, the other spots being entirely absent, excepting the one in the 

 cell. This $ therefore resembles the szra-group as well Augindes subhyalina. But the $ which I received 

 as florinda is certainly that of the present insect. Japan.
