67. THanaos IcELus, Lintn. 
Than'-a-os ic’-e-lus. 
Expanse of wings, one inch and a quarter. 
Upper side of the wings, blackish brown, sprinkled with 
pale bluish scales. A band, somewhat lighter than the basal 
part of the wing, crosses a little beyond the middle, heavily 
overlaid with the bluish scales, especially on the costal half. 
This is followed by a darker band with serrate edges, beyond 
which a paler shade extends to the outer margin ; while through 
the middle of this pale space there is a series of dark spots. 
All these shades and bands run from the costa nearly to the 
hinder margin. 
The hind wings are dark umber brown, with a terminal 
row of pale spots, and another similar row a little inside. 
Under side of the wings, lighter than above; and the spots 
of the upper side are repeated on the hind wings. The fore 
wings have a terminal row, and one preceding it, of length- 
ened dots, with two or three inside of this last. 
The early stages of this common species are not known. 
The perfect insect is on the wing during the middle of 
June.

There is a similar one half way between these and the hinder 
margin, and another, near the end of the cell. <A row of 
black points crosses the wing just within the outer margin,
