are subject to great variation, liein^- sometimes confluent so as to 

 cover most of the wing. 



Habitat, Northern Atlantic States westward. 



Tht' race a/igii/t'fcra does not differ in the imago. The larva 

 when young possesses red tufts instead of black ones as in 

 //uu-i/tata. 



Ila/'itat, Sierra Nevada of Cal., Pacific Northwest. 



In the race agassizii, the color of the insect is a deeper yellow. 

 It corresponds nearly with Ridgway's figure of "maize yellow" 

 (Ridg. Nom. Col. PI. \'I, f. 21.) while the race described above 

 are "straw yellow" (Ridg., PI. \T, f. 17). The brown marks tend 

 to become suffused by the yellow ground color, often largely dis- 

 appearing, but leaving a spot in the fourth band at the end of the 

 cell of the normal distinctness. This discal spot is a character- 

 istic feature of agassizii and only disappears in very heavily 

 marked specimens. This form differs almost enough to entitle 

 it to specific rank. 



Habitat, Coast region of California.

Bright ochraceous ; anterior wings very pointed, long.

1880 — Groie, Can. Kill., \"ol. Xli, p. 213. 



Pale yellowish, with irregular brown dots more or less numer- 

 ous ; along median vein outwardly a brown streak, continued to 

 apex more or less perfectly by two brown spots. Expanse, 45 mm.

Pale ocherous, the spots reduced, partly obsolete, conco- 

 lorous with ground, antl defined by pale brown. Middle of wing, 

 or most of it, overspread with purplish brown. Of the five rows 

 of spots, the basal ones are enlarged, the (jthers small and indis- 

 tinct on middle of wing. Exi")anse, 35 mm.
