are subject to great variation, being sometimes confluent so as to 

 cover most of the wing. 



Habitat, Northern Atlantic States westward. 



The race angulifera does not differ in the imago. The larva 

 when young possesses red tufts instead of black ones as in 

 maciilata. 



Habitat, 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. VI, f. 21.) while the race described above 

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

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

 appearing, but leaving a spot i*n 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. 



H. pura Neumoegen. 



1882 — Neumcegen, Papilio, \'ol. II, p. 133. 



Bright ochraceous ; anterior wings very pointed, long. 

 Secondaries whitish stramineous. On primaries, a brown discal 

 dot and occasionally some faint brown motlings suggesting the 

 markings of H. niaciilata. Expanse, 45 mm. 



Habitat, Arizona. 



H. longa Grotc. 



1880 — Grote, Can. Ent., Vol. XII, p. 213. 



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

 ous ; along median vein outwardly a brow'n streak, continued to 

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



Habitat, Florida. 



H. minima iVeu/ncvgcn. 



1882 — Neumcegen, Papilio, Vol. ill, p. 138. 



1892 — KuiBY, Cat. Lep. Het., \'ol. I. p: 211. 



arviillata Hy. Edwards. 



1884 — Hy. Edwarus, Papilio, Vol. IV, p. 76. 



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

 lorous with ground, and 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 others small and indis- 

 tinct on middle of wing. Expanse, 35 mm. 



Habitat, Mexico, Arizona.
