LETHE. By Dr. A. Seitz. 83 



uniformly brown, the grey admixture, which is especially distinct in the cell of epinienides, being absent, 

 and which are devoid of the dark shading of the subcostal. With Gkaeser he considers this form to be a 

 distinct species, although it tlies at the same time and localities as epimenidas. The two forms appear to us 

 to intergrade occasionally. Distributed from Central and West China to Japan, Corea and Anuu'land. The 

 buttertly in July; more plentiful in the north of the distribution-area; it flies chiefly in woods of high trees 

 settling with |u-eference on the trunks of trees (Graeser). 



L. satyrina Bt/r. (= naias Leech , styppax Oberth.) (30a). Forewing very obtuse at the apex, dark salyrinn. 

 brown, somewhat paler before tlie apex and distal margin; hindwing with lighter costal area and 2 black, 

 pale-edged, ovate submarginal spots. The forewing beneath with 2 small apical ocelli, the hindwing bearing 

 a row of G white-centred, yellow-ringed submarginal ocelli, tiie 2. and 3. being especially small. Throughout 

 the valley of the Yang-tse-kiang , from Shanghai to beyond the Tibetan frontier, in summer; at Chang- 

 Yang up to 6000 feet. — This species and the next one are in shape a transition to Mi/ro/esia, where they 

 indeed were placed by Oberthitr. 



L. butleri Leech {= turbilius Oberth.) (30 a). Larger than mtijrhin , the apex of the forewing not butk-ri. 

 quite so obtuse; beneath lighter, the brown discal lines of the hindwing much more widely separated from 

 each other. — From June to August, common in the Yang-tse-kiang valley, up to 7000 feet. 



L. lanaris Btlr. (= davidianus Pouj) (30 b). One of the largest species of the genus. Apex oi' /anaiis. 

 forewing more pointed than in the previous forms, the distal margin straight, erect. Beneath there are on 

 the forewing 5 double-ringed ocelli in a perfectly straight row; the 1. and 5. of the 6 ocelli of the hind- 

 wing are large, the 3. and 4. being small and the 6. double. Not rare, from Ningpo throughout China as 

 far as Se-chuen. Closely related to L. marginalis from Japan and North China, but the apex of the fore- 

 wing more pointed. 



L. oculatissima Poi<j. (30 a). A very variable species which is common all over Central and West oculniissim 

 China. The pale marginal area of both wings is constant, contrasting with the darker proximal portion of 

 the wings and bearing two black spots on each, one at the apex, the other before the anal angle. The 

 anal spot of the hindwing has always a pupil, exceptional!}' also on the forewing. Underside with a sub- 

 marginal row of ocelli, there being 5 ocelli on the forewing and 6 on the hindwing; two irregular dark 

 lines traverse the disc on both wings beneath. Moupin; Omei-shan. — occulta Leech is the eastern. Central occulta. 

 Clunese, form from Chang -Yang; it is larger and the forewing beneath has a row of only 4 ocelh, the one 

 neai'est the apex being obsolete. 



L. christophi Leech (29 e). This rather large species is at once recognized by a large scent-spot dn-istophi. 

 situated below the centre of the hindwing, this spot having the appearance of a large glossy oily stain; 

 otherwise the upperside does not bear any markings except a submarginal row of obsolescent black spots 

 on the hindwing. Beneath the edges of the wings are brownish, there being 2 dark lines on the disc, 

 which are partly straight, partlj^ somewhat curved; on the hindwings a submarginal row of small ocelli, of 

 which the \. and 6. (double) are distinct, while the others are obsolescent. In the ? the wings are somewhat 

 paler towards the distal margin. In July and August in Central and West China. 



L. serbonis Heic This Indo-australian species is represented in the Palaearctic Region onlj' by the 

 local form davidi Oberth. (30b). It is one of the largest Palaearctic Lethe, being above all brown with daz'iili. 

 dark, very faintly pale-edged, submarginal oceUi on the hindwing, the anal one bearing a pupil. The 

 exterior discal line of both wings beneath is excurved below the cell. The forewing beneath has 2 — 3 

 obsolescent ocelli at the apex, the hindwing bearing a complete row of submarginal ocelli, of which the 1. 

 and 6. are especially prominently marked ; the marginal tooth of the hindwing is strongly developed. While 

 in name-typical davidi the exterior discal line on the underside of the forewing is only slightly curved 

 distad, there occur specimens in which the line is produced into a large rectangular projection: ab. angulata angnlatn. 

 form. nov. Also in other respects dcviidi is so variable that one iuirdly meets with two identical specimens. 

 The bars crossing the cell sometimes are united to form a ring, sometimes they are parallel; often tiiere 

 is, besides the 1. and 6. ocelli, another conspicuous ocellus on the hindwing beneath, etc. To give names 

 to all such aberrations might be futile. We further mention but ab. flavofasciata Leech, which are ?? with f/avo- 

 the exterior discal line distally broadly reddish brown, while normal ?? resend)le the cf except in the distal fasciata. 

 area of the wings being paler. Like serlioiiis in Imlia, daridi is a common insect in West China, being 

 widely distrilouted and occurring up to 8000 feet. June, July. 



L. laodamia Leech. Above exactly as in davidi, only the ground-colour somewhat lighter brown, laodniiiin. 

 the black submarginal dots of the hindwing therefore moi'e conspicuous. Beneath, especially in the marginal 

 area, much paler, the forewing bearing a complete row of ocelli. A few specimens obtained b}' Leech's 

 collectors at Wa-shan and Omei-shan, in Julj^ at an altitude of 4 — 6000 feet. 



L. Camilla Leech (30 c). Above almost exactly as daridi, but the ocelli of the hindwing reduced to Camilla. 

 obsolescent dots. However, the d' bears before the anal angle a scent-spot with greasy lustre as in ehrixfop]u,
