HABITAT: Virginia.
Head black, with a yellowish spot in the front, and another on the top.
Eyes greyish, and shining like polished bell-metal. Antennæ pectinated or
combed, and longer than the thorax. Ocelli three. Thorax black, with
three small yellowish spots on the posterior part. Abdomen almost black
at top, {106}and underneath of a greyish yellow (as are all the legs),
having two short setæ or tails at the extremity. Wings membranaceous and
transparent; the nerves appearing, when viewed by a magnifier, to be
black and white, like the quills of a porcupine. Inferior wings shorter
than the superior.
Drury has figured the wings as of an uniform colourless appearance, which
induces me to consider that it may be distinct from the Linnæan H.
pectinicornis, that species being described by the great Swede with
"_signaturis_ nervisque fuscis albo subarticulatis." From the paleness of
the present species it is evident that the transverse nerves connecting the
longitudinal ribs of the wings in the typical species of this genus have
been overlooked, especially as the longitudinal nerves are correctly
represented. This genus and Corydalis, seem to form a connecting link
between Hemerobius and Perla.
