Libellula bifasciata, _Fabr. Ent. Syst._ 2. 374. (1793.)

HABITAT: New York.

Front of the head green. Eyes brown, large, and placed close together;

behind each are two yellow spots, one round, the other oblong. Thorax

hairy, and of a dirty brownish green; having on the sides two long yellow

spots placed obliquely above one another, the under one being the

shortest. Abdomen flattish, but triangular; in the male blue, but in the

female yellow. Legs black. Wings transparent, with a small brown cloud on

the tip of each; from whence issues along the anterior edge, a slender

black stroke near the middle of each wing. Another small brown cloud

begins on the anterior edge, and reaches about two-thirds cross the wing.

At the base of each, also, a third dark cloud of a longish form seems to

extend from the body near the anterior edge, to almost a third part of

the wing. Between these clouds the males have a remarkable white patch or

spot on each wing, and also another on the abdominal edge of the

posterior ones, all which are not to be discerned in the females.
