PINE. TWIGS. 
of an inch in length by the last of that month, and then becomes 
a pupa of a similar appearance, but varied more or less with 
dusky or black, and with rudimentary wings resembling a vest 
drawn closely around the middle of its body; the latter part of 
July changing to its perfect form with wings fully grown, and 
then no longer covering itself with foam, but continuing to the 
end of the season, puncturing and drawing its nourishment from 
the bark as before. The perfect insect a flattened oval tree- 
hopper, 0.40 long, with its wing covers held in form of a roof, 
its color brown from numberless blackish punctures upon a 
pale ground, a smooth whitish line along the middle of its 
back, and a small smooth whitish spot in the centre of each 
wing cover, its abdomen beneath rusty brown. 
The reasons why I regard this species as pertaining to the 
genus Aphrophora, to which Say had assigned it, instead of the 
genera in which it has recently been placed, will be found stated 
under a kindred species in my Third Report, No. 98. 
858. Saratoga spittle-insect, Aphrophora Saratogensis, Fitch. 
A similar insect with the same habits with the preceding, but 
differing from it in having the punctures uncolored, and the 
head above with its anterior and posterior margins parallel. It 
is of a lighter color than the foregoing, being pale tawny yellow 
varied with white. It is much more attached to the pitch pine 
than to the white pine, and is very common upon the small 
trees of that kind growing upon the sandy plains of Saratoga 
county.
