Maie. — Head brown, orbits of eyes, palpi, and collar yellow. Antennae black. Thorax deep 

 brown black with yellow markings ; two spots on each side in front, a short line at the base of the 

 wing and a subcircular ring behind ; sometimes this line is broken into spots. Abdomen deep brown 

 black, with a golden yellow band on the posterior part of each segment, encircling the body. Anal 

 tuft black, mixed with a little yellow. Third segment with raised black hairs mixed with a few 

 yellow ones. Legs yellow, femora and tibiae marked with black outside. Fore wings transparent 

 with brown borders, paler internally ; discal mark brown. Underside washed with yellow basally. 

 Hind wings with very narrow border and fringes brown. All the veins are brown. 



Female. — Similar to the male, but usually much heavier and larger, and it has the last segment 

 entirely yellow. The bands are also more prominent. 



Expanse : Male, 20-27 mm - 5 female, 20-35 mm - 



Habitat. — Canada westward to the Gulf of Georgia, Vancouver, New England and Middle 

 States, westward to Ohio, Illinois, Missouri, Kansas, and Nebraska. 



Type : One female. Coll. T. W. Harris, Boston Soc. Nat. Hist. 



Larva. — " Head with the lobes somewhat broadly touching, clypeus somewhat shield-shaped, 

 the paraclypeal pieces parallel, even, and therefore sinuate, all level with the surface, concolorous 

 and obscure; a low rounded lump at base of each paraclypeal piece; lower posterior ocellus 

 distinct and like the others. Head (in the alcoholic material) entirely brown, uniform, smooth, 

 labrum and epistoma colorless. Body normal, segments weakly 3-annulate, the second the highest, 

 incisures well marked ; joint 13 normal, the posterior half small ; thoracic feet short, brown. 

 Tubercles moderate, weak ; setae moderate ; spiracles brown rimmed, only slightly elliptical. 

 Crochets 12 to 15 in a row, remarkably reduced, resembling little setose spines rather than true 

 hooks, small, remote. Body robust, not slender." — (Dyar, MS.)
