Costal vein very distinct, and rather prominent, it and the sub-costal 
vein are remarkably parallel, the distance apart scarcely varying even 
to the smallest degree from the base to the stigma. Distance between 
the insertion of the tirst and second, and second and third veins 
about equal; the second fork about equally distant from the apex 
and first fork. Fourth vein nearly straight at its base, curving 
regularly but not sharply towards its apex, runs very nearly with the 
first fork of the third vein. 
The front of the mesothorax distinctly broader than the prothorax, 
the offset forming a distinct shoulder. The abdomen terminating 
suddenly and bluntly; no tail apparent. Honey-tubes very short and 
thick, slightly enlarged at the base, the length greater than but not 
, twice the diameter. 
When seen through a pocket lens, these (alcoholic) specimens appear 
dark brown; the antennae annulated alternately with dark brown, or 
fuscous and white; the legs brownish or dusky with the base of the 
femora and tips of the tibiae pale; the wings-transparent with the 
broad dark-brown or fuscous veins previously described. The body 
dark-brown except the tip of the abdomen, which is pale and shows 
traces of transverse dark bands. 
Wingless specimen .—Somewhat regularly ovate but sub truncate at 
the posterior extremity, or at least rounded very bluntly and sudden¬ 
ly to the tip. Antennae not quite as long as the body showing the 
light and dark annulations very distinctly. Eyes of this as well as 
the winged specimens reddish-brown. The ground color of the body 
of the alcoholic specimens, is pale dirty yellow, but the dorsal surface 
is chiefly occupied by broad transverse brown or fuscous bands which 
extend to the somewhat broad depressed portion of the lateral mar¬ 
gins; there is one band on each segment; a pale line runs along the 
middle of the back from the head to the tail. Legs as in the winged 
specimens. Scattered over the body are stiff spine-like, black hairs; it 
is also more or less covered with small tubercles. Honey-tubes as in 
the winged specimens, pale yellow. 
Length of winged specimen to the tip of the abdomen (which i s 
somewhat shrunken) .06 inches; to tip of the wings .15 inches. 
Prof. Bundy, of Sauk City, Wisconsin, from whom the specimens 
were received, makes the following statement in reference to them. 
“Abdomen of the female light green below, black above with four 
greenish spots; honey-tubes and tip of the abdomen white, head and 
thorax black, shining above. Eyes black; antennae light, banded with 
black; wings with widened veins and tinged with purple (reflection.)” 
“On Red Oak (Quercus rubra) leaves, in June, Sauk City, Wisconsin. 
On both sides of the leaves along the veins. Leaves becoming viscid 
from their ^secretions.” 
This is evidently distinct from the Callipterus quercus of Kalten- 
bach, which is of a pale ochre color throughout, and nearly smooth, 
and has the veins of the wings unmargined. It approaches somewhat 
closely to the C. juglanclis Frisch, which is found on Walnut. In 
that species the markings of the abdomen are almost exactly as in 
this, but the abdomen is much more drawn out and tapering than 
in this, but it is more than probable that the shrinkage caused by the 
alcohol has caused this to present the blunt appearance.
