Puhl. 2H. VI. Ok. LETHE. By Dr. A. Seitz. 85 



At once recognized by a scent-brush which is more than 8 mm long and placed exactly in the centre of the 

 cell. — In Japan and Corea, more in the plains; larva on l)amboo (Pryek). The butteiilies are extremely 

 common. Thej' are decided night-insects; in August they commence to swarm about 8 o'clock at night. 

 The cf d' are posed on the branch of a bush in the middle of a clearing in the wood. If one is taken 

 with the net , at once another comes to occupy the same place , so that I once might have caught dozens 

 without changing my position. 



L. hecate Leech (31 b). Similar to xkelis, but darker and the markings heavier. The ocelli on the hecate. 

 underside of the hindwing are much more distinct and sharper, being vestigial also an the upperside. The 

 cf has no scent-brush in the cell. — In West China (at Wa-shan and Ta-tsien-lu), not rare, fiom 2000 feet 

 upwards, in June and July. 



L. manzorum Ir'ouj. (31 c). Upperside much more variegated than in the previous insects. Forewing manzonm. 

 with apical ocellus, discal stripe and 2 dark lines across the cell. Hindwing with a row of ocelH which 

 are black distally, the 5. ocellus bearing a large white pupil. Underside yellowish gi'ey, all the transverse 

 lines thick, brown and straight, only the 1. and 5. ocelh large, all the others very small or replaced by 

 dots. — Central and West China, in June and July. 



L. gemina Leech (31c). Above uniformly dark earth-brown. Hindwing with a row of 4 large black gemina. 

 ocelli thinly edged with yellow. Beneath only the 1. and 5. ocelli are developed, having a large pupil, 

 the other ocelli being absent. It may be added that in contradistinction to xjircia the 1. and 2. oval rings 

 are contiguous above or nearly so. The last figure of row 5 on PI. 31 therefore represents the upperside 

 of sjirch ? , not of gemina , as erroneouslj' stated. — In West China , on the Omei-shan , in July ; appar- 

 ently rare. 



L. syrcis Hew. (31b, the fig. en-oneously called ijenihui , and 31 c). Above as in the preceding syms. 

 species, but both wings more rounded; on the hindwing above the 1. ring does not touch the 2., but is 

 rather remote from it; beneath, besides the 1. and 5. ocelli, there are others developed, though they are 

 small, and the disc is traversed by a straight dark line crossing the cell of both wings, being entirely 

 absent from fiemina. — Throughout China except the North, also in the plains, in June and July. 



L. titania Leech (31c). Recalling daridi; forewing above with sharply defined paler distal margin, titania. 

 all the ocelli of the underside on both wings with comparatively very prominent pupils. — West China, in 

 June and July. 



L. ocellata Pouj. (= simulans Leech) (31c). Brown above; there is a curved row of dark nebulous ocellata. 

 patches, visible onlj' when viewed at a certain angle, and extending from the costa below the cell: the 

 ocelli of the underside of the hindwing appear above as slightly pale-edged dots. The light marginal area 

 of the underside sharply contrasts with the dark basal area ; there are no ocelli on the forewing beneath, 

 but only a small white subapical band composed of 2 contiguous spots. — Exclusively Palaearctic like the 

 preceding species ; so far only met with in West China, where it appears to be a rarity ; in June and July. 



L. violaceopicta Pouj. (= calisto Leech) (31 c). The cf is uniformly brown above, the ? bearing a violaceopicta. 

 row of white ditfuse patches before the margin of the forewing and an abbreviated white band distally to 

 the apex of the cell. Beneath the forewing has 3 ocelli, the hindwing 6, the last one of these having always 

 2 pupils. The basal area of the hindwing beneath is traversed by numerous irregular angulate and inter- 

 rupted silvery lines. — In West China, in June and Julj\ 



L. sldonis Hew. (31 d). Brown above, both sexes bearing 2 small white costal spots in the distal sidonis. 

 half of the forewing. Beneath there are abbreviated curved silvery white bars in the cell, beyond the cross- 

 veins and near the apex, being especially distinct in the cf . The basal half of the hindwing beneath traversed 

 by irregular silver-lines which are interrupted several times. Distal edge of wings almost regularly undulate, 

 the hindwing with a hardly vestigial tooth at the 3. radial vein. — Afghanistan, North and Central Kashmir, 

 and elsewhere in the Himalaya. In the southern part of Kashmir, in Kulu, which is outside the Palaearctic 

 Region, the species is represented by L. vaivarta Doh., which is said to differ from sidoiiia in the structure 

 of the cf-genitaha. 



L. siderea Marsh. Similar to sidonis, but smaller and above uniformly dark brown without markings; siderea. 

 the ocelli of the hindwing beneath form an irregularly curved row. — A Sikkimese species of the Indo- 

 Australian fauna; Leech, however, records a specimen obtaiend by KRiECHELiJORF in July at Mupin, for 

 which reason we mention the species here. 



L. nigrifascia Leech (31 e) is at once recognized by the broad scent-stripe which in the cf extends nigrifascia. 

 from the apex of the cell to the middle of the hindmargin and is dilated at the veins. On the underside 

 the discal stripe is bordered with white on the outer side, being excurved distally to the apex of the cell. 

 From Chang- Yang. One of the largest Palaearctic species of Lethe. — At Pu-tsu-fong there occurs another,
