secortdaries whitish, except in apical and costal region, with a more or 

 less complete, punctiform extra median line. 



Expanse. — 1.24 to 1.44 inches (31 to 36 mm.). i 



Habitat.— l^o\^ Scotia; Canada in July; New York, June to August; 

 Newton, Massachusetts; Missouri; Glen wood Springs. Colorado, 

 September 1 (Barnes). 



This is a common species, hence my material is not especially good 

 There are twenty or more specimens, but not well distributed as to 

 locality and few of them dated. It is probable that the species 

 occurs throughout the Eastern United States, but may not extend far 

 southward. 



The rang-e of variation is much like that given for heterodoxa and is 

 chiefly a matter of contrast. In some examples the base is quite a 

 clear yellow and on this a deep rich red makes a striking- specimen. 

 In others everything- is dull, or there is a g-rayish tinge. This is the 

 only species in which an obvious outer line is usual on the under side. 



Mr. Strecker's tvpe is the usual Colorado form, in which the con- 

 trasts are not quite so great. Yet he would hardly have made the 

 error had he not placed it at once with roiiunoldcs as the closest ally. 

 From that species it is, of course, easily distinguished.

Five examples, all of them from Newark and Elizabeth, New Jer- 

 sey, are before me. The species is not represented in any of the large 

 collections, and yet it has a considerable range. Druce records it from
