This is essentially a forest-loving species, usually occurring 

 beneath leaves and other debris on or along the borders of heavy 

 hardwood timber. The males are often attracted to light and the 

 females to a bait of molasses. The latter sex appears to be' much 

 the more abundant, especially in Indiana, and 994 of the 1232 

 adult specimens examined by Hebard were females. The short 

 separated tegmina and shining black color easily distinguishes 

 them from allied species, while the males are with difficulty sepa- 

 rated from those of fuluesccns and virginica. Plataiuodes uni- 

 color and Ectoltia litJiophila Scudder (1862, 417, 418) are synon- 

 rnys, being based respectively on the male and nymph, while, as 

 noted above, Ischnoptera intricate! Blatch. (1903, 186) is the fe- 

 male, the type of that sex, as designated by Hebard, being a spec- 

 imen taken in Crawford Co., Ind., July 2, 1902, and now in my 

 collection.
