adjacent area. The lower ocellus consists of a single black spot, rather 

 indistinct, and without white central point and surrounding ring. A very 

 faint, submarginal black line and a marginal streak ; secondaries same as 

 primaries, an ocellus in the same position as the second one on primaries 

 and resembling it. 



Underside : primaries woodbrown but much mottled with other shades, 

 many irrorations of darker color ; submarginal to the two ocelli is a 

 wavy, distinct brown band formed into crescents toward the inner 

 margin ; the upper of the two ocelli is like the one on the upperside,' the 

 lower is exactly like it only somewhat smaller. Between the ocelli and 

 the margin is a comparatively broad, dark brown band ; a marginal and 

 submarginal distinct lines close together. 



Secondaries : more mottled with grayish than the primaries ; a very 

 broad fascia in the center of the wing, extending from costa to base 

 parallel to outer margin ; the row of six ocelli placed in the usual posi- 

 tion, the first is rather small, with a minute white dot in the center ; next 

 is much larger with distinct white central point ; next consists of a small, 

 black point only ; next is a small one, with a distinct white central point ; 

 next is as large as the second and like it ; the last one like the first. 

 These ocelli are very constant, more so .than in any other species. Be- 

 tween this row and outer margin is a brown band corresponding to that 

 of the primaries ; a marginal and submarginal fine, distinct streaks. 

 Fringes all brown. 



9 expands 46 mm. Resembles the $ in all particulars except the fol- 

 lowing : the two ocelli on upperside of primaries are exactly alike and are 

 like the upper one of the male. The one on the secondaries is larger 

 and with a distinct, white central point. 



Underside : the two ocelli on the primaries are slightly large and of 

 same size. The row of ocelli on secondaries are practically like those of 

 the male. 



Habitat : Mt. Tamalpais, Marin County, California. Right 

 across the bay from San Francisco, collected by Dr. Behr many 

 3'ears ago, probably between 1860 and 1870. 



Types, 2, S , 2 9 , collection California Academy of Sciences. 

 Several cotypes. 



This species is readily distinguished from any other by its 

 small size, darker color and very distinct markings. Named 

 for Hans Herman Behr, the beacon light of Californian Lepi- 

 dopterology, whose name will be held in strong remembrance 

 as long as Californian butterflies are collected and studied. 



Thanaos pernigra n. sp. 



Upperside : primaries entirely blackish-slate, with a very thin sprinkling 

 of grayish hairs ; three very small, white dots arranged diagonally, in the
