3-jointed ; first joint broad at base, conical ; secoud joint as long or a little longer 

 than first, swollen at base, tapering; third joint extremely slender, cylindrical, 

 about one-sixth as long as second joint. Superior appendages about one-half the 

 length of inferior, 2-jointed ; first joint stout, ovate; second joint slender, longer 

 than first, tapering to an acute point. Ventral plate of female brown, with 

 numerous gray scales and a few scattering hairs, about as long as broad, termi-

The writer has not had an opportunity of examining this and 

 the preceding species, but from Kincaid's descriptions they seem to 

 be very nearly the same. P. cinerea has been found to be a wide- 

 spread and rather variable species, so that it is not at all improbable 

 that when the field is more closely worked the identity of these two 

 species will be established.

 '■ Dark, with whitish hair on thorax and gray on abdomen ; wings thinly 

 clothed with gray hair and a gray fringe, which at the posterior margin is about 

 twice as long as the width of a cell ; legs dark, with whitish hair. Antennse not 

 quite as long as breadth of wing, black at base of joints, and each joint in male 

 with a dense whorl of white appressed hair, which gives the antenuse a very 

 heavy and thick appearance; in the female the whorls ai'e quite loose. Wings 

 much broader than in the other species, and more blunt at tip. The inferior pair 

 of male appendages are very long, slender and gradually tapering, strongly 

 curved upward and nearly black, with white hair beneath, the superior pair not 

 half so long, tapering and diverging. Cannot make out the structure of the 

 female ventral plate. Length of wing 1.6 mm."

Body dark brown, densely clothed with light bluish-gray hair. Legs brown- 

 ish, with light hairs and scales. Wings rather acutely angulated at tip of the 

 second simple nervure; length 1.3 mm.; breadth .5 mm.; posterior fringe very 

 dense, one-half the breadth of wing; same color as hair on body ; anterior quite 

 narrow, but also very dense; hair on veins uniformly distributed ; light bluish- 

 gray, with scattered darker hairs; cubital bifurcation one-sixteenth the length

 and dense whorl of erect hairs; terminal spike of 13 long, without perceptible 

 enlargements; nodes dark, pedicles lighter; whorls light grayish, except last, 

 which is snow-white; pedicles 4-8 longest, one and one-half length of their 

 nodes. Tarsi darker than rest of leg, densely clothed with scales and hairs. 

 Inferior pair of male genitalia well developed, length one-half the breadth of
