Pupa. Length 10.75 mm., width above the middle of the abdomen 

 5.85 mm. ; quite broad and stout, abdomen wider than high ; dull 

 brownish black, making the coloration almost uniform, in some speci- 

 mens, however, the color is brownish mottled with blackish ; stigmata 

 brownish with pale yellowish rim. Body somewhat shining, quite 

 roughened, indistinctly reticulate, well clothed with pale translucent 

 brownish hairs of fair size, mostly pointed, often slightly clavate, and 

 beset with short little spines, giving the hairs a roughened appearance. 

 The hairs arise from small inconspicuous buttons. 



Described from living specimens. 



The larva of this butterfly, though often of various shades, 

 mimics well the flower heads of the buckwheat; reclining as 

 it does among the pale grayish-green and coral red colors of 

 the flower it is often overlooked, though when once noticed 

 the mimicry does not seem so strong and the larva is conspicu- 

 ous enough. The larva of Lycaena behrii, antiacis and some 

 others girdle themselves quite strongly, differing thereby from 

 Thecla dumctorum, which girdles itself imperfectly, if at all, 

 and pupates largely in rubbish, in contradistinction to the more 

 exposed pupation of the former. None of my dunietorum 

 pupae have as yet emerged, and it is probable that it passes 

 the winter in the pupal state. 



23. Chrysophamis helloides Bdv. 



Not uncommon in places where its food-plant grows. Lone 

 Mountain, Presidio, Mountain Lake, Lake Merced, etc. 



24. Lycaena heteronea Bdv. 



Not found here at present. The locality given by Behr is 

 the hilly region in the vicinity of Mountain Lake. 



'Mature larva. Length (at rest) 18.25 mm., width above middle 

 6 mm. ; pale translucent ultra ash gray, or with a slight greenish 

 tinge, very nearly the color of the dorsal surface of its food-plant 

 (Eriogonuni sp.) ; ordinary onisciform, though slenderer than the 

 larva of Lycaena antiacis, behrii or Thecla duinetoruin ; rather rounded 

 and somewhat thickly clothed with rather smooth slender white pile 

 and less numerous little white dots, which under the microscope appear 

 as ovoid tubercles with constricted bases. Under the naked eye the 

 larva presents a rather fuzzy aspect ; segmentation not as distinct as 

 in Thecla dumetorum; markings quite obscure. A pale ground color 

 line on each side of the median one, then two more or less oblique
