portion of the fourth and fifth joints, which is snowy white; the extreme apex or each 

 femur, and about two-thirds of ihe exterior portion of each tibiae, is also white; the 

 three segments which terminate the abdomen are red. 

 Inhabits Xorth America. Taken by Mr. Doubleday, at Trenton Falls. 



The foUowing is a description of the species determined as 

 tej^mijialis: 



Female.— Length, 12 mm. Anterior margin of the clvpeus 

 gently rounded out, not crenulate laterally, with a deep median notch; 

 front below oceUi and the posterior orbits coarsely, irregularly 

 reticulate; lateral ocehi on a line between the third and fourth tuber- 

 cules; postoceUar line distinctly shorter than the intraorbital line; 

 second antennal joint haK the length of the third, third longer than 

 the fourth and fifth, fifth about haK the length of the fourth, seventh 

 distinctly longer than the eighth; mesoscutum reticulate, with two 

 longitudinal depressed areas which are anteriorly finely punctured 

 and posteriorly striato-punctate; scuteUum reticulate laterally, 

 shining and sparsely punctured in the middle; venation weak; hypo- 

 pygidium gently, gradually tapering to the apex, see figure &d. 

 Black; three apical segments rufous; fourth, fifth and base of sixth 

 antennal joints beneath, spot on dorsal apices of femora, tibise (in 

 part) exteriorly whitish; wings hyaline, strongly dusky beyond the 

 stigma (except the fore wings which have the apex hyaline) ; venation 

 pale brown or yellowish, stigma and cost a dark brown. 



Hampton, Xew Hampsliire. One female collected June 21, 1911, 

 by S. A. Shaw; Ottawa, Canada (Ashmead collection). 



This may only be a form of following species, as it differs only in 

 the shape of the hypopygidium. 



ORYSSUS aEMORRHOroALlS Hairis. 



Oryssus hsemorrhoihulis Haeris, Rept. Ins. Mass., 1841, p. 394. — Xobtox, Trans. 

 Amer. Ent. Soc, vol. 2, 1869, p. 350.— Psovaxcher, Nat. Can., vol. 10, 

 187S, p. 227; Petite Faiftia Ent. Can. Hjon., 1883, p. 237. 



Harris, after saying that lisemorrhoidalis was the same as terminalis, 

 described his species as follows: 



Female. — Her body is black, rough, before, and smooth behind, with the last three 

 segments of a blood red color. The outer side of the fourth and fifth joints of her anten- 

 nae, her knees, and a line on the outer edge of her skins, are white. Her feet are dull 

 red. Her wings are clear and transparent, with a broad, 6mok\- brown, transverse 

 band, beyond the middle of the first pair. Her body measures nearly six-tenths of an 

 inch in length. 



The following is a description of a species which is considered to be 

 Jisemorrlioidali^-} 



Femalt. — Length, 12 mm. Anterior margin of the clypeus rounded 

 out, not crenulate laterally, with a distinct median notch: front below 



1 Rather than describe the two species, which have usually been considered as one. and called trrminaiit, 

 thecames " terminaUs" and "hxmorrhoidalis'' are used. By an essmination of the types, if they sire still in 

 existence, the matter may be set straight.
