Winged individuals. (See fig. 11.) The general color is 
gray varied white and ash brown. Antennae on very distinct tuber¬ 
cles; very long, extending considerably beyond the end of the 
abdomen and reaching nearly or quite to the tips of the wings; 
third joint longest, fully equal in length to half of the body; 
fourth about two thirds the length of the third, fifth about as long as 
the fourth, sixth, very short not more than one-fifth the length of the 
fifth, seventh nearly as long as the third, slender. Three ocelli, or 
what appear to be ocelli, very distinct, readily observed with an or¬ 
dinary pocket lens. Prothorax depressed at the side 
wing-like expansion each side. 
From the back of each of the first three or four abdominal 
ments arise two distinct, slender, somewhat curved spines, those 
the third segment usually the longest. 
Honey tubes, rather short, not reaching quite to the end of the 
abdomen, distinctly enlarged at the base, and tapering to the tips; the 
enlargement at the base as seen frofn the side is abrupt. Wings large, 
the three discoidal veins of the front wings somewhat curved in¬ 
wards, the second most so; the second rather nearer to the third than 
to the first, especially in the middle and thence to the margin; the 
fourth or stigmatic vein very strongly and sharply curved near the 
base. Most of these veins, especially the fourth and the forks of the 
third, expand at their extremities, forming dusky spaces which present 
a very marked character. The sub-costal vein is strictly parallel with 
j the costa. Stigma short and rather small. The hind wings small and 
delicately transparent, veins minute and pale; the sub-costal bends in¬ 
ward or backward quite distinctly and abruptly at the point where 
the second discoidal joins it, leaving a triangular space between it 
and the costa in which there is a distinct, abbreviated, transverse, dark 
line or elongate dot, pointed directly toward-the insertion of the second 
vein. Basal joints of the antennae dull-yellowish, with a narrow darker 
ring at the apex of the third and forth joints; more or less of the 
fifth of a transparent whitish color, forming an annulus, sixth and 
seventh dusky. Legs pale. General color of the body pale grayish- 
brown in dead specimens, but the specific markings of living speci¬ 
mens are as follows; Head pale brownish with a narrow white median 
line, and sometimes a white line around the eyes above. Eyes red. 
Prothorax same color as the head, with three more or less distinct, 
very narrow abbreviated, longitudinal, white lines; abdomen marked 
with a few white dots somewhat regularly arranged, powdered with 
white behind the honey-tubes. These white lines and spots appear to 
be formed by a very fine white powdery substance. The spines on the 
back of the abdomen are black or pale at base and black at the tip. 
The honev-tubes brown, white at the immediate tips. 
%> 
Wingless Specimens. (Not fully grown.) A very pale transparent, 
pea green color; eyes dark; apica portion of the antennae dusky; tibiae 
dusky at the base; honey-tubes pale green. The form is oblong, 
widening slightly posteriorly, tip of the abdomen rounded; no pow¬ 
dery substance apparent on them; on the contrary the surface is smooth 
and shining. They are located chiefly along the sides of 
veins on the under side of the leaf.
