this tube hangs downward and diverging outward, two small thread-like appendages, 
which are two-jointed, the joints twice as long as thick. 
Thf legs are long and slender, the hind pair slightly longest They are densely 
coated with a fine short incumbent beard, and the shanks have a pair of spurs at 
tlieir tips. The feet are five-jointed, the joints cylindric and successively diminished 
in length, the last one ending in a pair of small black simple hooks. 
The wings are laid flat upon the back, one upon another when the insect is run¬ 
ning or at rest. They reach much beyond the end of the body, being almost double 
its length, and in the male cover and hide from view the forceps. The four wings 
arc nearly alike in size, form, texture, and in the number and position of their veins. 
They are thrice as long as wide, the fore pair being slightly longer and narrower, 
gradually widening from their bases through two-thirds of their length and rounded 
at their ends, thus being elongated egg-shaped. They are destitute of any plait or 
fold, and are pellucid and faintly smoky, the anterior pair perceptibly more so than 
the hind pair. Along their inner side they are slightly fringed with extremely fine 
short hairs, which incline backward, and on their outer side are similar hairs incum¬ 
bent upon the marginal vein. Their disk is occupied by numerous veins running 
lengthwise of the wing, nearly equidistant from and parallel with each other, some 
of them forked. They are blackish in the fore wings of. the male and pale brown in 
the hind wings. In the female they are pale brown in the fore wings and dull 
whitish or colorless in the hind wings. They are connected together by many small 
and more slender transverse veinlets of a whitish color. 
The outer portion, or costal area, of the wings is broad and widened toward its 
middle, thus appearing like the wing of an Orthopterous rather than a Neuroptcrous 
insect, and it is destitute of any discolored spot or stigma toward its tip. On its 
inner side this area is traversed lengthwise by a slender slightly flexuous and nearly 
colorless vein, which terminates in the marginal vein. Along the outer side of this 
vein at irregular distances are short oblique veinlets, about twelve in number, con¬ 
necting this longitudinal vein with the margin. About five of the first of these vein- 
lets are straight and closer together, forming short rhombic cells between them. The 
succeeding veinlets become more oblique, longer and curved, their middle portion 
being more longitudinal than their ends, and most of these curved veinlets send off at 
right angles one or two short straight branches to the next veinlet or to the longitudi¬ 
nal vein, thus dividing all the middle portion of the costal area into extremely 
irregular cells. In the hind wings these veinlets are fewer, about eight in number, 
and all nearly straight. Along its inner side this longitudinal vein is connected to the 
rib vein by from three to six oblique and transverse veinlets placed at irregular dis¬ 
tances. 
The rib vein is slightly thicker and more deeply colored than the other veins. 
Along its inner side are seven short veinlets connecting it to the next vein, the three 
first of these being oblique and farther apart, thft others transverse. 
The several veins which ramify the middle and inner portions of the wing, are all 
branches of two principal veins, which are given off from the inner side of the rib 
vein near its base. These two veins are designated the externo-medial and the 
intcrno-medial. The former extends along the inner side of the rib vein its whole 
length, the latter along the inner side of the axillary or anal vein. There is a beauti¬ 
ful correspondence between these two veins, both in their branches and their princi¬ 
pal connecting veinlets. Each vein sends off three branches, the first branch being 
also once forked, thus making five veins ending in the margin of the wing. 
The externo-mcilial vein parts from the rib vein above and little more than its 
diameter distant from the root of the intcrno-medial. It diverges very gradually
