The male and female of this species were taken on a small pine, 

 probably Pin us rigida, at Karner, N. Y., April 2^, 1907. 

 They were observed pairing, consequently there can hardly be any 

 question as to their belonging to the same species. 



Male. Length i 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. Halteres 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. Harpes 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
