108 Bulletin of the Brooklyn Entomological Society Vol. XIV 
Associated with this male type were several females which 
have an ovipositor of the type of E. chlorophylloides and it is 
possible that the female of FE. subchlorophylla is similar to that 
species. Specimens in copula should be pinned together when 
captured. 
Erioptera furcifer new species. 
Generally similar to E. chlorophylla. Male hypopygium with the pleural 
appendages very dissimilar in shape; dorsal appendage slender, broadest 
and flattened at the base, narrowed to the blunt rounded apex which is 
heavily chitinized. Ventral pleural appendage slender, on the outer (pos- 
terior) margin far before the tip a very long, slender, blacked spine which 
is almost straight, the proximal face with subappressed hairs, the tip 
blackened. The slender tip of the appendage beyond this spine is a little 
shorter than the spine itself, the two appearing as a forked apex to the 
appendage, diverging at an angle of about 125°. Penis-guard as in the 
group, at the apex on either side with a long recurved chitinized hook; 
gonapophyses in caustic potash mounts, pale, flattened, the distal portion 
only a little wider than the base, the outer margin with minute teeth which 
extend down to about midlength of the gonapophyse. 
Holotype, 3, Plummer’s Island, Maryland, June 24, 1908 (H. S. Barber). 
- Of the above species, E. chlorophylla and E. chlorophylloides 
form one group of species, E. subchlorophylla and E. furcifer a 
second group, separated by the form of the gonapophyses.

Mr. Edmund H. Gibson has resigned from the U. S. Bureau of 
Entomology to enter upon a new field of endeavor. He believes 
that entomology can be put on a dignified professional business 
basis just as law, medicine or engineering. He is breaking away 
from custom believing that after the pioneer work is in hand the 
field will welcome other entomologists. Mr. Gibson’s headquar- 
ters, for the time being, will be Alexandria, Virginia. 
Gerris argenticollis Parshley originally described from Massa- 
chusetts was taken in White Plains, N. Y., April 29, 1917.
