Wings with large dense scales on the apices of the veins ; the 

 first sub-marginal cell longer and narrower than the second 

 posterior cell, its base nearer the base of the wing, its stem 

 nearly one-fourth the length of the cell, stem of the second 

 posterior cell not quite half the length of the cell; posterior 

 cross-vein slightly longer than the mid, about its own length 

 distant from it. 



Length — 3 mm. 



$ . Resembles the 9 in general appearance. The legs have

of its distal portion being composed of two equal lobes very 

 slightly connected posteriorly. The terminal segment is most 

 remarkable, and is best described by referring to Felt's figure. 

 The harpogones are smaller than the harpes, both consisting of a 

 broad basal plate-like structure rounding abruptly to a short, 

 stout blade-like segment armed with a conspicuous spine and 

 with its apex abruptly truncate. Unci broad, plate-like, fused 

 mesially to form a keel-like structure. Setaceous lobes small, 

 each bearing four or five long, stout setae. 



Habitat. — Lahaway, New Jersey (J. B. Smith) \ Florida 

 (D. W. Coquillett) ; Old Forge, New York State (E. P. Felt) ; 

 Riode Janeiro (Dr. Fajardo).

 sent me by Professor E. P. Felt. Coquillett described it as an
