ARGYNNIS. By Dr. Th. Lehmann. 419 



tlie black markings strongly rednced, as in adinnte, especially on the hindwings. On the imdei- surface the fore- 

 wings from base to outer half cinnamon-red, beyond that buff. Apex and termen brown; the upjjer marginal 

 and 2 subajiical spots well silvered. Hindwings rusty-brown from base to the brownish-yellaw submarginal 

 band, mottled with lighter brown. All the spots well silvered. $ above like cJ, with the dark markings some- 

 what heavier. Under surface of forewings uniformly reddish as far as the apex, only the upper angle of the 

 cell buff. Hindwing generally fawn-coloured with the submarginal band somewhat lighter; some specimens 

 have the ground-colour nuicli darker, with the band very distinct. The silverspots very prominent. Expanse: 

 (J 2,6", $ 2,8 — ^3,0". seniiramis is quite common in the neighbourhood of San Bernardino in southern Cali- 

 fornia, especially in the mountains separating the S. Bernardino Valley from the Mohave Desert. 



A. inornata Edw. (86 e) resembles in its markings rupeslris. but is much larger and somewhat paler, inomata. 

 Forewings strongly arched, produced apically. ,^ above bright fulvous, much obscured from base to mesial 

 band; the two marginal lines united to a broad band. The black markings moderately heavy, only at the 

 disk rather thin. Under surface of the forewings cinnamon-brown, tiie apex buff. Hindwings reddisli-brown 

 to the second row of spots, the submarginal area clear buff, slightly shaded with the dark ground-colour 

 toward the anal angle. All the spots large, pale yellow, without any silver. $ above rather paler than (J, 

 the basal area deep orange-red, the outer portion, and especially the discal and marginal spots on the hind- 

 wings faded to whitish-yellow. Under surface of the forewings orange-red instead of cinnamon-brown. Hind- 

 wings pale greenish-brown, mottled with yellowish. The spots very large, but generally not silvered, only in 

 some exceptional cases sprinkled with a few silvery scales. Expanse: (J 2,5", 9 2,7". Originally described 

 from a ,^9 from Downieville (California), inornatd is also found in Nevada (Virginia City, Edwards), but is 

 rather rare in collections, being extremely shy and, on account of its rapid, restless flight, very difficult to 

 catch. It never alights on flowers, but settles, in order to rest, on the leaves of trees, never for more than a 

 second at a time, very different from zerene and monticola. 



A. atossa Edu\ (86 d) closely approaches the following adiante. ^ above bright fulvous, but slightly atoiisa. 

 obscured at the base. The markings all very greatly reduced, almost entirely absent on the hindwings. Outer 

 margin of both wings bordered only by a single fine line, otherwise almost unmarked, only on the forewings 

 we find at the inner angle 3 small s^jots, being all that is left of the usual submarginal lunides. Under sur- 

 face of both wings pale buff, suffused with bright red at base and inner margin of forewings; on the hind- 

 wings the basal and discal areas very feebly obscured; all markings in cell, at apex and termen obliterated. 

 The spots on the forewing and hindwing without any silver, frequently very faint altogether and hardly 

 recognizable. Expanse: (J 2,4", $ 2,8 — 3,0". atossa is a very rare species, or possibly only an extreme variety 

 of adiante Bsd. from southern California. The exact locality where the (^ type was found, is unknown; but in 

 June 1889 Burrison captured several $$ near Tchachape, in a little side-valley by the border of a nar- 

 row stream, 4 miles from town, at an elevation of about 4200 ft. In June 1905 F. Grimnel took on Mt. 

 Pinos among a lot of tj^^jical A. eurynonie a specimen of atossn, which was by Coolidge regarded as an ex- 

 tremely light form of euri/nonie. Since than nothing has been heard of this sf)ecies. 



A. adiante Bsd. (= adiaste Behr) (86 d). o above bright fulvous, lightly obscured A\ith fuscous at base, adiante. 

 the black markings rather slight, especially on the hindwings where the median band has been reduced to a 

 thin, broken line; the submarginal lunules small, not joining the marginal line; the postdiscal spots on both 

 wings minute. Under surface of the forewings pale fidvous, the apex much lighter, the basal area orange-red. 

 The markings of the outer half almost completely obliterated. Hindwings light buff, shaded with pale fawn- 

 colour proximally. Termen brownish, all the spots without any trace of silver, grey-yellow, finely margined 

 with brown proximally, sometimes hardly visible. $ very much like ,^, but with the markings of the upper 

 surface heavier, the basal area as well as the inner half of the forewings beneath tinged with deeper red. 

 adiante is a very constant form, which, unlike most of the other Californian Argi/nnis, seems to develop 

 neither variations, aberrations or local races (Behr). It does not occur on the coast, but only in the interior 

 of southern California (near Los Gatos, near Scarsville in Santa Clara Co.); in some years it is rather conimon, 

 but always local. Its southern limits are not yet known. 



A. artonis Ediv. (87 d) represents a transition from adi<in.te to the eurynome-gvouii, being the first artonis. 

 of a group of forms which are all more or less related to eurynome, and are by many authors regarded as mere 

 varieties or local races; whether this is just, cannot at present be decided, on account of our scant know- 

 ledge of the life-history of these forms. Only of eurynome and egleis we know the early stages. (^ easy to di- 

 stinguish from eurynome ,^ by the entire absence of silvery scales on the s])ots of the inider surface, which 

 are, moreover, not so long nor so nnich produced as in that species. Under surface without the dark
