120 OENEIS. By Dr. A. Seitz. 



egg is longitiiflinrtlly ribbed. Larva brown-yellow, with striped greenish head, and dark longitudinal lines: 

 on grass. Pupa with brown-yellow abdomen and light green anterior portion ; at the sides of the head two 

 black arcuate spots, along the back a dark-edged green line; it hes on the ground between the roots 

 of grass without a cover of silk-threads (Sandbekg). The butterflies are on the wing in July in swampy 

 meadows and are not rare. 



amnion. O. ammoH Ehr. (40 f ) was described as a form of hore. Upperside dust-grey, without eye-dots, the 



basal area somewhat darker. The hindwing is beneath very pale, being so little pencilled that the median 

 band appears heavy and dark on the background. In the high Altai , 7000 — 9000 feet , the cf rf' very com- 

 alda. mon; in July. Here belongs also the form alda Aust. (40 e), which exactly agrees with cmimon above, differ- 

 ing from the same only in the median band of the hindwing beneath being broad at the costal margin 

 and disappearing behind in the dark basal area instead of narrowing towards the anal margin ; even with 

 a lens I cannot find a trade of eye-spots in the type-specimen (Tring Museum), which has kindly been lent 

 pansa. me. — pansa Chrit-f. (40 f) is without ocelli like the preceding , but on the whole a little more brightly 

 coloured; larger, strongly glossy brown, the distal margin of the hindwing with a strong yellowish red tint. — 

 Polar regions of Europe and Asia, also in the Altai ; the last two forms especially must be considered repre- 

 sentatives in the Old World of the American taijgete. 



crambis, O. crambis frr. (= subhyalina Elw., oeno Scudd.) (40 f). A chiefly Nearctic insect. Wings more 



hairy than scaled, above uniformly dust-grey, with the fringes conspicuonsly chequered, as is also the costal 

 margin of both wings beneath. The hindwing beneath much more densely pencilled than in the other 

 Oeneis; the median band has exactty the same colour as the basal area of the hindwing beneath, only 

 oeno. being separated from it by band-Hke white scahng. — In oeno Bdr., from Lapland and Sibiria, this white 

 a/so. scaling is more prominent, smear-like. — In also Bdv., like«ase from Siberia, the white scaling has so entirely 

 disappeared that the hindwing beneath, from the base to the external edge of the median band, is dark 

 brown, being coarsely and evenly pencilled with black, contrasting slightly with the but little paler distal 

 third of the underside of the hindwing. — The butterfly is not rare in North America, although local like 

 all Oeneis. The Old Worhl forms are but little known , and were formerly united with the closely allied 

 semidea Sai/, which, however, appears to be purely American. 



tttnga, O. tunga ^tgr. (= also //ere) (40 g). This large species is almost without markings above, the uni- 



formly dark earth-brown colour assuming a lighter yellowish tint before the distal margin; the underside 

 of the hindwing is very uniformly scaled dark, but the median band nevertheless is not difficult to perceive, 

 although its colour does not contrast -with that of the ground. — From the Sajan district. 



buddha. O. buddha Gr.-Grsh. (40 g). Above light sand-yellow; forewing with 1 — 3 eye-dots in a lighter 



band, the discocellular and the median nervure, sometimes also the subcostal, conspicuously black. On the 

 hindwing the markings of the underside distinctly shine through. The underside bright in markings; the 

 forewing show a black-brown border to the distal band, the discocellular and the distal edge being dark; 

 the hindwing have heavy white veins, which traverse like rays the dark-edged, almost even, median band. 

 The type before me (from the Tring Museum) has on both sides of the forewing 3 eye-dots, on the hind- 

 wing above only one subanal oceUus. — Tibet. 



mongoUca. O. mongolica Obcrth. (40 g). However closely this species resembles certain specimens of larpcju, 



the shape of the wings, the ground-colour and the eye-dots accidentally agreeing, there is hardly any resem- 

 blance in the underside of the two insects: there is in moni/o/ica no trace of the median band, which in 

 ffirjjcja is so dark and strongly prominent and moreover bordered with white and traversed by white 

 veins. According tho OberthIie's figure, which we copy, the hindwing beneath is sand-colour, sparsely irror- 

 ated with grey, bearing a dark sinuous median band. — In eastern Mongolia, already at an altitude of 

 about 550 m (Oberthue). 



urda. O. urda Er. (40 g). Very variable, above yellowish brown, greyish brown or uniformly dust-grey, 



with at least 2 usually pupilled ocelli on the forewing and often an entire row on the hindwing. In sjiite 

 of all \ariability the species is easily recognized by the median band of the hindwing beneath bearing 

 at the elbow a pointed tooth which projects distad beyond the apex of the cell. On the Amur and in 

 Transbaicalia, in May and June, not rare in rocky places. While many Oeuiitf almost exclusively settle 

 on the hare ground or on stones, urda visits flowers with preference according to Guaesee. — Large dark 

 umbra, brown specimens are named ab. umbra by Staudinger. 



nanna. O. nanna Mill. (= hulda Stgr.) (40 g). One of the largest and finest Ocnch of the Old World. 



Above leather-yellow, with the basal area dai'k on both wings; the ochreous distal area traversed by dark 

 veins and bearing a chain of ocelli which are partly pupilled, at least 2 standing on the forewing, there 

 being between them usually some additional smaller ones, 5 — 7 on the hindwing. The hindwing beneath is 

 yellowish, similar to the upperside, the cell being proximally pencilled with grey; on the hindwing the row 

 of ocelli is prominent also beneath, while the basal area is often quite dark and frecjuently marmorated. At 

 Podrofka on the upper Annir, not rare; in the Altai, in larch-woods in rocky situations, in July. — As ab.
