The male and female of this species were taken on a small pine, 
; SESE A Wa esis al 
probably Pinus rigida, at .Karmmer, N..¥. Apuil-27,) 1907: 
They were observed pairing, consequently there can hardly be any 
question as to their belonging to the same species. 
Male. Length 1 mm. Antennae nearly as long as the body, 
thickly haired, dark brown; 14 segments, the fifth with a stem two- 
thirds the length of the subcylindric basal enlargement; terminal 
segment narrowly oval, subacute distally. Palpi; the first segment 
broadly oval, with a rather conspicuous sense organ internally, the 
second a little longer, narrow, subquadrate, the third a little shorter, 
more slender than the second, the fourth about twice the length of 
the preceding, more slender; face fuscous, eyes large, black. 
Mesonotum shining black, sparsely and irregularly clothed with 
short, yellowish hairs. Scutellum a dark reddish brown, post- 
scutellum and abdomen nearly shining black, sparsely clothed with 
fine, yellowish hairs. Wings hyaline, costa reddish brown, sub- 
costa uniting with the margin at the middle. MHalteres nearly 
uniform fuscous yellowish. Legs fuscous yellowish, the incisures 
variably tinged with deep red, the distal tarsal segment reddish 
brown; claws long, strongly curved, denticulate, the pulvilli longer 
than the claws. Genitalia; basal clasp segment long, stout, taper- 
ing; terminal clasp segment rather long, almost pediceled, broadly 
rounded and with an enlargement near the distal third; dorsal 
plate broad, tapering, broadly rounded. WHarpes short, stout, ap- 
proximate, with an acute, chitinous spine posteriorly and a semi- 
circular, dark, chitinous thickening dorsally. 
Female. Length 2.5 mm. Antennae extending to the base of 
the abdomen, thickly haired, dark reddish brown; 13 segments, 
the fifth subsessile; terminal segment prolonged, subcylindric, tap- 
ering to an obtuse apex. Palpi; the first segment stout, broadly 
rectangular with a conspicuous sense organ internally, second a 
little longer, more slender, the third as long as the second, more
