ones of the same color. In the spiracular area the ground seems 

 somewhat darker. Stigmata pale yellowish with a narrow, brownish 

 rim. Lateral line (which is the plainest of the markings) whitish. 

 A slight indication of purplish at cephalic end of the largest speci- 

 men (described). I could find no indication of caudal cornicles for 

 honey dew. A very sluggish larva. 



Described from several living specimens in the final instar, 

 taken in Marin county, May 23, 1909. 



Pupa. Length 12 mm., width at abdomen 5.30 mm.; stout; thorax 

 rather high and humped, rounded ; head gently rounded. Markings 

 obscure, coloration pretty uniform, light green, pale greenish gray on 

 wing covers, and most distinctly greenish on abdomen ; reticulated with 

 grayish white, this latter color being distributed in about the same 

 proportion as the ground color. Pale green dorsal thoracic line, with 

 blackish where it meets the abdomen line, more obscure on abdomen 

 where it is plainest caudad. Some small, darker greenish subdorsal 

 spots, hardly in a depression. Stigmata obscure, cream color. An ill- 

 defined pale greenish lateral stripe. Wing venation marked by very 

 pale grayish white. An irregular ventral circle of rusty brown crot- 

 chets. The raised reticulated surface is quite fine, in contradistinction 

 to that of Thecla dumetorum. With the exception of the wing covers 

 the pupa bears numerous little white spots, which, under the micro- 

 scope are defined as little short-peduncled stellate discs. A smaller 

 pupa is more heavily marked. 



Described from living material. 



The pupae were fairly well girdled and produced imagoes in 

 June and July of the same year. 



25. Lycaena pheres Bdv. 



Not uncommon in May and June in the vicinity of Lupinus 

 chamissonis, upon which the larva feeds. This butterfly is 

 subject to considerable variation on the underside of the 

 wings. It is sometimes confounded with L. fiilla of the 

 mountains. 



26. Lycaena xerces Bdv. 



Quite rare, though formerly an abundant insect. Lone 



Mountain, Lake Merced, etc.
