GRAPTA VI. 



Female. — Same size. 



Similar in form and on upper side similar in color and markings; beneath 

 nearly uniform wood, or olivaceous brown, or vinous, with markings as in male, but 

 indistinct and more or less obsolete; silver mark very slender and open, slightly 

 barbed. 



Found in the Rocky Mountains, in Colorado, and in California and Oregon. 



I am indebted to R. H. Stretch, Esq., for the drawing of the larva, and the 

 following descrij^tion. 



Mature Larva. Head black, angular, bilobed, sjiiny and with a s])'mj tuber- 

 cle at each of the uj^per angles; color of body black with a broad, greenish-white 

 dorsal stripe, which on the anterior segments is clouded with black; on each seg- 

 ment, on this stripe, is a fine V-shaped black mark having its angle at the dorsal 

 spine; the spines form .seven rows; the dorsal greenish-white, wanting on the first 

 four segments ; the first lateral row of same color, present on all segments from the 

 second; the second lateral row black, the third greenish- white, wanting on the 

 first four and terminal segments, and springing from an infra-stigmatal line of 

 same color; all the spines are thinly covered with short, bristling, concoiored hairs, 

 excejit that those near the tips of the white spines are blackish. 



Found on nettles, (Urtica) at Congress Springs, Santa Clara Co., California. 



Mr. Henry Edwards also writes, San Francisco, 2Gth March 1872. " The 

 larva No. 4 on your plate is same as one I raised last year, which produced the 

 male I now send you (Satyncs). I had two others exactly like it, but they died 

 before coming to maturity. Their food was the stinging nettle and I could not get 

 any of this pi mt in the city to keep them alive. I mention this to show that the 

 coloring of the larva is constant, as if the same in four individuals, it is pretty good 

 proof that the likeness extends throughout the species." 



Satyrus forms one of the remarkable group, the several members of which re- 

 semble one or other of the phases of C album, and to which I have referred in the 

 notes to Comma. It as yet has nowhere been found common. Mr. Mead saw not 

 more than half a dozen specimens in Colorado, where Zephyrus was abundant. I 

 have also received it from the Island of San Juan, taken in comj^auy with G. 

 SileniLS.
