be more or less obscured or obsolete. In the females the outer two- 

 thirds of the wings, except for a moderately broad border, may be 

 golden rusty, or the outer half of the fore wings alone may be 

 dull rusty. 



On the lower surface the ground color is darker than in northern 

 specimens and is tinged with purplish. On the fore wings the sub- 

 marginal row of small crescentic dark cinnamon spots seen in north- 

 ern specimens is represented by a conspicuous scalloped black band ; 

 the irregular broken dark cinnamon band crossing the middle of the 

 outer half of the wing is replaced by a rather broad continuous black 

 band edged outwardly with white ; and the two bands across the cell 

 are black and heavy. On the hind wings the checkered pattern is 

 conspicuously outlined in black, which is abruptly set off from the 

 general ground color. 



Doctor Holland's figure of the underside of this species shows a 

 specimen about midway between the specimens from Boston at hand 

 and those from the District, though nearer the former. 



In addition to the species of Theclinae given in the preceding 

 pages, the following should be looked for in the District :
