In the type series as now represented in the Museum of Comparative 
Zoology are three specimens, a male from Bethel, Maine, which is chosen 
as the lectotype, a female and a broken specimen. I am indebted to Mr. 
Banks for the above data. 
The male hypopygium has the pleurites much stouter than in chloro- 
phylloides; the dorsal pleural appendage is a little longer than the ventral, 
of nearly equal width for the entire length or the apex a very little ex- 
panded, obliquely truncated, with the extreme outer angle blackened. The 
shorter and more slender ventral appendage is suddenly flattened and 
expanded at the tip, on the caudal or outer margin before the apex with a 
small, usually slender, blackened spine which is shorter than the width of 
the blade at this point. The tip beyond this spine is sometimes blackened 
and, in the type, one of the appendages appears claw-like. Gonapophyses 
small, each side consisting of a flattened plate whose inner posterior angle 
is produced strongly laterad into a short blackened horn whose tip is thus 
strongly divergent from its mate of the opposite side; the penis-guard has 
a slender arm on either side which form a collar-like structure passing 
beneath the hooks of the gonapophyses. 
Lectotype, Bethel, Maine (Miss Edmands); Blue Hills, Massachusetts, 
July 16 (C. W. Johnson) ; Sacandaga Park, New York, June 18, 1914 (C. 
P. Alexander); near Philadelphia, Pennsylvania (C. W. Johnson). 
Erioptera subchlorophylla new species. 
Generally similar to E. chlorophylla. Male hypopygium with the pleural 
appendages very dissimilar in shape, the dorsal one expanded into a flat- 
tened blade at its apex; ventral appendage shorter and more slender, at 
the extreme tip with a long, stout blackened spine, directed caudad and 
placed at right angles to the appendage. Gonapophyses complex, the lat- 
eral chitinized arms slender, at the tips expanded into flattened paddle-like 
blades whose outer margin bears several minute acute teeth; horns of the 
penis-guard curved, projecting slightly beyond the level of the gonapo- 
physes. 
Holotype, &, Riverton, New Jersey, June 3, 1910 (C. W. Johnson).
