C. oetus Bdr. (50 e). Above giw-brown, the apex of the forewing lighter, fringes grey, 2 brown marginal oeius. 

 lines; the forewing ^^ith 2 small round black-grey spots in j^ellow-brown rings, in the (^ with brown scent-scale 

 stripe. Beneath yello^^'ish grej', the basal half finely striated with brown, forewing with 2 black-brown eye- 

 spots with ochre-yellow ring and white pupil. The anterior eye-spot is very large, extending over 3 cellules, 

 the posterior is smaller. Both wings with 2 brown marginal and a submarginal line. Prom North California. 



C. charon Edw. (50 d). Above brown, forewing in the o with 1 or 2 black spots without rings, in the charon. 

 2 lighter with 2 eye-shaped spots in ochre-yellow rings. The dark browai scent-scale spot of the (j* extends 

 into cellule 3. On the under surface there are in both sexes eye-spots with yellow rings and white pupils instead 

 of the black spots. Both wings are beneath brown, finely striated with dark brown all over, hindwing with 

 dark bro^vn, dentate median line and a row of more or less distinct, small, black, white-pupilled eye-spots. 

 — Egg. larva and pupa are almost exactly as in meadi. The longitudinal lines of the larva are commonly purer 

 white, the pupa sometimes black-brown or black-grey. The butterfly flies near the ground in grassy places 

 and visits especially composites. Flies in June to August. Locality: the west of North America, from British 

 Colombia to New Mexico. — sylvestris Edic. (= phocus Edw.) is according to Holland a form of charon, with sylvestris. 

 the eye-spots on the underside of the hindwing indistinct. (Kirby in his Catalogue has given sylvestris Edw. 

 as the oldest name for oetius Bdv.) Tlie figure called sylvestris on pi. 50 d belongs to sthenele. 



C. paulus Edw. (50 d). On the upper surface similar to charon, but beneath always with 2 eye-spots paulits. 

 on the forewing in q and Q. The liindwing has also one or 2 eye-like spots on the upper surface. On the un- 

 der surface the hmdwing is grey in the distal third, finely striated with dark bro^vn, proximally bordered by 

 a dark bro'mi dentate line. In this marginal area are placed 5 or 6 black eye-spots with white pupils and 

 yellow and brown rings. From California and Nevada. 



C. sthenele Bdi\ (50e, the form erroneously called sylvestris on pi. 50d also belongs here). Above brown sthenele. 

 with 2 round black spots on the forewing, of which in the (J only the upper is pupilled with white, but in the $ both 

 have white jjupils and brownish yellow rings. The species is recognizable by the broad, dentate dark median band 

 on the underside of the hindwing, which is strongly constricted in two places and both proximally and especially 

 distally is broadly margined ^Wth whitish grey. In the marginal area a row of eye-spots, sometimes indistmct. 

 From California. 



C. wheeleri Edw. (= hoffmani Strech.). Similar to nephele, but larger, especially the $. Ground-colour wheelcri. 

 brown. The fo^e^^'ing above has 3 eye-spots. The apical eye-spot is double, consisting of a larger ocellus in 

 cellule 5 and a smaller in cellule 4. Both are surrounded by a common narrow light yellow ring. In 

 the 2 these eye-spots are placed on a broad light brown band and 2 eye-spots are also present on the hind- 

 wing above before the anal angle. The under surface is not brown as in nephele, but in the (J light grey, in the 

 2 light j^ellowish grey, finely striated with brown. Forewing with a dentate median stripe and 3 nearly 

 straight marginal lines, all brown. Hindwing with a broken and a second dentate median stripe and 3 undulate 

 lines at the margin. In the (J there is on the forewing a small 4th eye-spot in cellule 3, these eye-spots are 

 surrounded in pairs by 2 yellow rings with brown exterior ring. In the $ these brown rings are particularly 

 large, measuring 7 mm. in diameter. On the hindwing beneath there are 6 black eye-spots with white pupils 

 in light yellow and brown rings. Nevada. 



C. behrii G^rinnell. Much smaller than the preceding, only 43 mm. in expanse. Brown, forewing with hehrii. 

 a black, white-pupilled apical ocellus, margined with somewhat lighter brown, a black spot in cellule 2, an 

 indistinct submarginal and a brown marginal line. Hindwing with black anal spot. Beneath forewing wood- 

 colour, marbled vnth. darker, with 2 black, white-pupilled ocelli, an undulate brown median band, a broad 

 band between the eye-spots and the distal margin and 2 marginal lines likewise brown. The hindwing is more 

 mixed wdth grey. A broad band traverses the middle. In the marginal area is placed a row of 6 eye-spots, 

 the 2nd and 5th large, the rest small. The 3rd eye-spot has no pupil, the others are all white-pupilled. The 

 broad Vjand behind the middle and the 2 marginal lines are as on the forewing. The $ measures 46 mm. and 

 only differs from the rj in having the black spots on the upper surface all pupilled with white. From Tamal- 

 pais, a mountain in Marin County on the Bay of San Francisco in California. In the collection of the Californian 

 Academy of Sciences. Collected by Behr. 



C. glaucope Fldr. (= friedenreichi Stgr.) (50d). Above brown with a broad red-yellow band on both glaucope. 

 wings, in which are placed on the forewing a double ocellus before the apex and a single one in cellule 2, on 

 the hindwing sometimes a black dot in cellule 2. The under surface is lighter and striated with dark brown, 

 on the forewing with the same band and eye-spots as above, but on the hindwing with a narrow, almost straight 

 ochre-yellow stripe, extending from the middle of the costal margin nearly to the anal angle. Behind this stripe 

 are placed on the costal margin 2 dark brown spots. Brazil (provinces of St. Catharina and Parana). — boen- boenning- 

 ninghauseni Foetterle (50e) is only a form of glaucope in which the distal half of the hindwing beneath is not ''««««'"• 

 striated with dark brown and the light yellow median stripe is distally widened. From Itatiaya.
