Male. — Antennae violaceous-black above, tawny beneath. Labial palpus 

 sordid white, third joint black. Head black. Collar dull yellow. Thorax 

 lustrous bronze-black; patagia laterally striped with pale yellow; meta- 

 thorax with long, sordid-white lateral tufts ; beneath, small clusters of shiny 

 silvery scales. Abdomen lustrous coppery black; segments 2, 4, and 7 

 narrowly banded with pale yellow or sordid white above, not beneath, anal 

 tuft short, broadly wedge-shaped, black, slightly edged with white. Pos- 

 terior tibiae very rough throughout, lustrous bronzy and tawny on inner 

 side, spurs sordid white, tarsi with first joint thickened, blackish ; posterior 

 joints pale tawny, Forewing with costa and margins broad, black ; vitreous 

 spaces much reduced and more or less flushed sordid white ; fringes broad, 

 brown black ; beneath heavily flushed with tawny-yellow, except for veins, 

 discal mark, and outer margin, which are black. Hindwing transparent, 

 with margin bronzy black, clearly defined ; nearly as broad as cilia, which 

 are brown-black. 



Female. — Forewing opaque, lustrous black, except a small nearly cir- 

 cular area before the discal mark, which is sordid white or tawny-yellow. 

 The abdominal segments 2 and 4 and sometimes 6 narrowly banded with 

 pale yellow above, not beneath ; anal tuft short, rounded, black. Posterior 

 tibiae rough, metallic black throughout. Otherwise like the male. 



Expanse : Male 17 to 20 mm., female 18 to 22 mm. 



Distribution. — Eastern and Midwestern States, Texas, Colorado ; Sas- 

 katchewan, Manitoba. 



Types. — Female. In the Boston Society of Natural History. 



Remarks. — The original description of sanborni, said to be based on two 

 females and one male, applies to the female alone. It is doubtful whether 

 Hy. Edwards had male examples of the species, as sexual dissimilarities 

 would have made their recognition unavoidable. The types are two fe- 

 males. The specimens were collected by F. G. Sanborn, at Andover, 

 Mass., on September 7, 1867, on flowers of Lacinaria scarlosa, which since 

 has been proved to be the food plant. Examples of both sexes have been 

 reared from the bulbous roots. Hy. Edwards described Aegeria morula 

 from a single male, labeled "Texas, J. Ball," in the Neumoegen collection 

 now in the United States National Museum. The antennae must have 

 been missing, as female antennae have been substituted. J. Ball, the col- 

 lector, lived at Dallas, Tex., the probable type locality. 



Beutenmiiller's illustration of morula is not of a female, as stated, but 

 of a male and probably based on the type, as it is shown with male an- 

 tennae of the subspecies sanborni. The males of anthracipennis differ
