the ground color on tlie outer half between the nearly parallel radiating lines of the 

 secondary color. In other specimens the ground color occupies more than half of 

 the inner half and extending down to inner margin. Underside fuscous with second- 

 ary color on apical cilia. Hindwingsl ight gray, cilia fuscous, under side same. Ab- 

 domen : upper side terra-cotta, but more ochreous than on forewing ; anal segment 

 grayish-white, underside pearly white, a double row of black dashes on either side 

 of segments 6 to 9. Legs same color as underside of abdomen, tinged and mottled 

 with brownish black. Alar expanse 9 to li mm. 



Described from twenty-four specimens bred from Artemisia Cana- 

 densis Michx., received in June, 1902 and 1903, from my friend Mr. 

 Jos. H. Reading, of Chicago. I also have one specimen of what is no 

 doubt this same species, collected by Dr. R. E. Kunze, July, 1900, 

 Pinal Mountains, Arizona; Mr. Busck advises me that in the U. S. 

 National Museum are specimens of this same species, unnamed, bred 

 by Miss Murtfeldt on Asteniisia, from St. Louis ; indicating a rather 

 extensive range. Type U. S. Nat. Mus. , No. 6S16. Cotypes Am.

Larz'a. — Cylindrical, slender, tapering evenly from 7 to anal segment, annulate. 

 Length 8 mm. Width i mm. Head .6 mm. Head small, rounded, slightly bi- 

 lobed, clypeus evenly triangular, extending nearly to apex. Ocelli black, antennre 

 minute. Head yellowish-brown, retractile under 2. I'rothoracic shield moderate, 

 triangular, mottled brown, bisected by paler dorsal line, and an almost black spot 

 each side of dorsal line on posterior edge. Anal shield pale yellowish-green, small, 

 shining but not chitinous. Thoracic feet clear yellowish-green, tipped with brown ; 

 abdominal feet normal, small, circles complete. Skin dull sordid green, not shining. 

 Tubercular plates not developed, tubercles small black raised points, no other marks 

 except discoloration from food showing through dorsal area. Setre very weak and 

 minute. 



Pupa. — Length 5 mm., width across thorax 1. 5 mm., very slightly flattened. Sur- 

 face generally smooth, tapering gradually to blunt point end of anal segment, which is 

 armed with a radiating zone of very minute stifil hairs before the apex. Vertex of 

 head and upper part of clypeus full, rounded, and extending up above the eye cases, 

 latter small, round, prominent and well defined. Beneath the eyes, on each side of 

 labrum, is a small raised process consisting of a parallel pair of narrow short eleva- 

 tions, which may indicate the maxillary palpi. Labial palpi broadened out about the 

 middle of its length and terminates just before the prothoracic feet, about one half 

 length of wing cases. Latter with antennre cover fifth abdominal segment. Dehis- 

 cence : Pupal skin is very flimsy and fragile and difficult to rescue without fracture 

 from its cocoon, but there appears to be one long break on each side of labial palpi, 

 this organ remains attached at posterior end, and remains united to labrum and clypeus. 

 The cap on vertex of head and eye covers are entirely separated ; antennal cases re- 

 main attached to wing covers. 



The terminal leaves of this plant resemble a long silvery green
