very short, slightly covered with gray filaments; legs moderately long; 
wings colorless, very much longer than the body; wing-ribs, black; 
stigma and veins, brown, stigma linear, rather long, actuely angular 
at each end; distance between the first and second veins at the tips 
full eight times that between them at the base; third vein nearer to 
the second towards the base than at the tip, much nearer to the sec¬ 
ond at the tip than the second is to the first. 
SCHIZONEURA PINIOOLA. n. Sp. 
This singular and beautiful specimen w T as discovered the 20th of Ap¬ 
ril 1878, at Carbondale, Illinois, on the tender shoots of young white 
Pines, feeding on the base of the young leaves or the sheath around 
the base of the new growth. Their presence is indicated by slender 
snow-white, silky webs. They are usually covered with a clear white, 
cottony secretion w T hich appears to shoot out from the body in little 
ribbon-like flakes. 
Wingless specimen ,—when freed from their cottony covering are al¬ 
most uniformly pale green; before their covering is disturbed, they 
are covered w T ith a white powdery substance on the back, green dots 
showing through it along each lateral margin. The form is somewhat 
elongate-ovate, the head being quite broad and blunt, and in some spe¬ 
cimens grooved above near the front; the body is rather rough above, 
with transverse ridges and tubercles. The antennae are scarcely half 
the length of the body, six-jointed, the fourth joint is shorter than 
the fifth or sixth. Honey-tubes wanting; no tail apparent. 
Winged specimen ,—Unfortunatly I was unable to examine the win¬ 
ged form when it made its appearance, and can now describe it only 
from a single specimen mounted in Canada balsam. Body imperfect 
and somwhat shrunken; the abdomen is less than the thorax; the widest 
point being the anterior portion of the meso-thorax; the protliorax 
is very short, it and the head, which is broad, being brought closely to¬ 
gether the latter, apparently, somewhat drawn into the former. The 
eyes are large and black; the front of the head rounded and blunt. 
The antennae more than half the length, but not reaching to the tip 
of the body; third joint longest, nearly, but not quite equal in length 
to the fourth and fifth united, its inner side with a series of little 
transverse ridges: fourth, fifth and sixth joints about equal in length; 
the sixth with a little spur at the end. 
Wings erect in repose, anterior pair with the third discoidal vein 
once forked; posterior pair with two branch veins; unusually delicate 
and perfectly transparent, so that when placed on a glass slide and 
held toward the light they can scarcely be traced by a pocket lens, (I 
speak only of them in the balsam); veins very slender and delicate. 
The first and second discoidal veins arise very closely together, but 
diverge rapidly, the second being much more oblique than the first; 
the third is wholly obsolete at the base about half the distance to the 
fork; the fourth vein is long, at its base it curves slightly for a short 
distance, then is nearly straight, running obliquely to the hinder portion
