Clemens' description of this species is misleading. He speaks of 

 the fore wings as reddish brown with " markings pure brown." The 

 type at Philadelphia, corresponding with what we have in the col- 

 lection as nitidanum^ has the pale areas of the fore wing yellow with 

 an overshading of faint rose color and the dark markings brownish 

 3^elllow. The general color of the insect is decidedly more yellow 

 than brown.

This species has been incorrectly listed as a synonym of concinna- 

 nu77i Clem.ens. It resembles the latter somewhat in pattern but is 

 quite different in genitalic structure. Strangely enough specimens of 

 the true foedanum have always been mixed with olivaceanum Fer- 

 nald in our collections. 



Harpe of male genitalia figured from specimen in National Collec- 

 tion from Ocean View, Va. ; female from a reared specimen without 

 locality label (" July 27, 93 "), also from the National Collection.
