female a little larger, and the ocelli circled with fulvous on both surfaces. 

 No locality given, but spoken of as very rare. Sthenele seems indeed to 

 be one of the rarest of the Californian butterflies. Mr. Henry Edwards 

 informs me that all the examples of this species hitherto known in collec- 

 tions are believed to have been taken in a certain locality now included in 

 the limits of San Francisco, and that no other locality is known. Practi- 

 cally the species is extinct. The same is true of Lycaena Xerxes, which 

 was taken at same spot with Sthenele, but no where else. I have received 

 from Dr. Behr and Mr. Edwards some half a dozen examples of Sthenele at 

 different times, of which I now have 3^,1 %■ The £ expands from 1.3 

 to 1.4 inch, the $ 1.2. The upper side agrees with the above description. 

 Beneath, the fore wing is yellow-brown, with a slight gray shade over outer 

 half. The hind wing is brown just at base and next hind margin, and all 

 the interior part of the wing is whitish, and on this area is abroad angular 

 brown band, unlike anything in our other species. The inner side of this 

 band is circular and is roughly and irregularly crenated ; the outer side is 

 sinuous, there being a broad and deep rounded sinus on the subcostal 

 and another on the median interspaces, while between these projects a 

 broad, angular dentation ; in one g and the £ this is rounded. The 

 ocelli are as described by Dr. Boisduval. This species belongs to another 

 group from those which follow. 



Silvestris. — The male expands about 1.5 inch and female 1.5 to 1.6 

 inch. The former is dark brown, with two small blind ocelli on fore 

 wing, and a black sexual dash along the lower side of cell. The under 

 side is tinted yellow ; the two ocelli are large, pupilled white, and with 

 yellow rings. The hind wing has one or two white dots near angle, 

 indicating obsolete ocelli ; across the disk a broad indistinct band, not 

 darker than the rest of the wing, its outlines very irregular — on the basal 

 side rather serrated, on the outer side against the cell two long serrations 

 projecting with a sharp and deep sinus between them. The female' is 

 lighter colored above, 'the ocelli larger, pupilled and with a hazy yellow 

 ring, and yellowish nimbus over the adjacent area ; there is a small ocellus 

 at anal angle, and the fringes are alternately light and dark, whereas in the 

 male they seem to be wholly brown. The under side is more grayish than 

 in the male, and the markings more distinct. Mr. Baron sent me quite a 

 number of perfect specimens, obtained by him in northern California. In 

 my Catalogue, 1877, 1 have credited this species to Nevada and Montana, 

 but I am not now sure of these localities.
