9 . — Differs from the male as follows : 



Frous, epistoma aud labrum brownish. Labial palpi with a distinct light- 

 colored spot at the anterior outer angle (there is an obscure trace of such a spot 

 in the % ). Dorsum of thorax brown, with no reddish tinge; median band ob- 

 scure, no humeral band. Sides of 4th and 5th abdominal segments with a yellow 

 spot at base. Appendages longer than segment 10, hardly as long as 9, simple, 

 cylindrical, straight, apex acute. Vulvar lamina (PI. V, fig. 10) bifid, internal 

 margins of the lobes almost touching each other, apices rounded, hardly reaching 

 to one half the length of the 9th segment. Basal streaks of anterior wings 

 reaching to the 1st antecubital, with clearer yellowish spots. Basal streak of 

 posteriors a little longer; basal spot with small yellow spots aud veined with 

 yellow. Pterostigma longer; 6 postcubitals on anteriors. Discoidal triangle of 

 anteriors crossed by one vein. One cross-vein in the internal triangle of left 

 anterior. 



Total length, %, 29.5 mm. ; 9 29 mm. Abdomen (incl. app.) 20 mm. Ante- 

 rior wing 22 mm. Posterior 21 mm. Pterostigma % 1.5 mm. 9 ~ nmi- 



The above description is based on one male, one female from 

 Pictou, Nova Scotia, taken June 25, 1889, by Mr. Wm. Sheraton. 



I suppose this species to be one of the three — borealis, frigida and 



glacialis — named, but not described, by Dr. Hagen in 1875. As I 



am unable to determine which of these three names belongs to this 



species, I have preferred to avoid any possible confusion arising from 



a use of one of them. I name this species after Dr. H. A. Hagen, 



whose kind aid to me, at various times, I thus acknowledge. With 



his assent I have published the three new species of this paper.

% . — Vertex black. Frons and epistoma greenish white. Frons with the usual 

 median groove above, and a transverse black band in front of the eyes, extend- 

 ing also on the sides of the frons. Labrum cream-yellow. Labium black ; labial 

 palpi varying from yellowish with the inner edge margined with black, to en- 

 tirely black. Occiput black above, a brownish spot behind. Rear of eyes black. 



Thorax reddish brown, with light-colored hairs; dorsum with a very broad 

 median blackish band, not reaching upwards to the wing-bases, and a blackish 

 humeral stripe. At times the black extends over almost the entire dorsum. A 

 black stripe on the second lateral suture; an irregular black band runs from the 

 2d to 1st lateral suture above the spiracle. Pectus reddish brown, sometimes 

 marked with blackish. 



Feet black, coxse partly reddish brown. 



Abdomen black ; segments 2 and 3 mostly yellowish on the sides, and pruinose 

 on the dorsum ; 2 with a blackish spot each side at base, and sometimes blackish 

 at apex; apex of 3 blackish, especially on the sides. Abdomen sometimes prui- 

 nose underneath. 



Genitalia: viewed from the side the internal branch of the genital hamule is 

 shorter aud more strongly curved than in Hageni, and the external branch does 

 not appear bifid (PI. V, fig. 5j. Viewed ventrally (fig. 6), the two divisions of 

 the external branch in Hageni are represented ; the one (c) is similarly directed,
