most generally present, and which may be considered typical of the 

 species, are the ist, 3rd and 5th. 



Secondaries white, sometimes with a faint discal dot, a series of 

 small marginal dots near the apex, and two faint submarginal dots 

 near the apex and anal angle respectively. Any or all of these spots 

 may be wanting. 



Beneath as above, except that the markings are usually somewhat 

 paler. 



$. — White, immaculate. 



Expanse of wings, 1.30 inches ; length of body, 0.^55 inch. 



Habitat. — Massachusetts, (Harris). New York, (Edwards). Can- 

 ada, (Saunders). 



Larva. — "Length 1.75 inches; cylindrical, head small, bilobed, 

 black and shining, with a faint brownish streak between the lobes, 

 scarcely visible above, and a few short brownish hairs, 



" Body black, with a slight shade of brown, and sprinkled all over 

 with very minute whitish dots, scarcely visible without a magnifier. 

 On each segment a transverse row of shining black tubercles, each 

 emitting a tuft of hairs of the same color. On each side, from sixth 

 to twelfth segments inclusive, is a double row of orange-colored spots 

 — those composing the lower row more conspicuous than those in the 

 upper one. There is also a faint continuation of these spots on seg- 

 ments anterior to the sixth, but they are scarcely visible to the un- 

 aided eye. 



" The under surface is paler, of a blackish brown color ; feet black 

 and shining ; prolegs brownish, with a wide ring of shining black. "

This species is very similar to H. textor in its habits. It is very 

 abundant in New York and extends into the Southern States.
