NORTH AMERICAN NEUROPTERA. 39 



but is much shorter than in Hageni ; wliile the other (6), incurved towards its 

 fellow of the opposite side, is hardly as long as (c,) and much shorter than its 

 honiologue in Hageni. Genital lobe moderate, apex hairy. 



Superior appendages longer than the 10th segment, black. Viewed from above, 

 they converge slightly from the base to about half their length, after which 

 they slightly diverge ; each appendage becomes thicker towards the apex, espe- 

 cially on the inner side, and ends in an acute point. Viewed from the side, each 

 appendage is nearly straight, or slightly curved upwards at the middle; the 

 thickness of the appendage at the base is somewhat less than at the apex, which 

 is formed as in Hageni; the inferior margin bears six to eight denticles. 



The inferior appendage as in Hageni, but viewed from the side, the concavity 

 of its curve is not so pronounced. 



Wings hyaline. Anteriors with two very short dark brown basal streaks, one 

 between the subcostal and median nervules, the other between the submedian 

 and postcostal nervules; the first of these two extends hardly one-fourth of the 

 distance to the first antecubital, the second is slightly longer. Posteriors with a 

 very short dark brown basal streak between the subcostal and median nervules, 

 extending one third the distance (or a little more) to the 1st antecubital ; and a 

 dark brown basal spot as in Hageni. Costa and pterostigma as in Hageni, but the 

 pterostigma has a brown vein at each end. Membranule dusky ; 6-8 antecu- 

 bitals on anteriors, 6 on posteriors, 7-11 postcubitals on anteriors, 8-9 on poste- 

 riors. Two or three rows of discoidal areolets Discoidal triangle of anteriors 

 crossed by a single vein, of posteriors free Internal triangle of anteriors of 

 three cellules (one wing of one specimen has two cellules). No internal triangle 

 on posteriors ; no hypertrigonals. One basal postco.stal cross- vein, placed 

 nearer the base than the 1st antecubital.

Measurements of the %. Total length .33-36 mm. Abdomen (iucl. app.) 

 22.5 — 24.5 mm. Superior appendages 1.5 mm. Anterior wing 25 — 27 mm. Pos- 

 terior 25 — 26 mm. Pterostigma 1.5 — 2 mm. 



The above description is based on three males from Manchester, 

 Kennebec Co., Maine, taken July 10, 11, 16, 1888, by Miss Mattie 

 Wadsworth, and two males from Pictou, Nova Scotia, taken July 

 26, 1889, by Mr. Wm. Sheraton. 



In 1875, Dr. Hagen gave the following localities for this species: 

 British America, Vancouver's Island, White Mountains and Massa- 

 chusetts. 



The identity of my specimens with Dr. Hagen's species is estab- 

 lished by the fact that one of the males which I possess from Maine 

 was seen by Dr. Hagen, and has the label " proxima" in his hand- 

 writing, attached.

Plate V, figs 1, 7, 8, 9, show the inferior appendage and the geni- 

 talia of the second abdominal segment of the male, and the vulvar 

 lamina of the female, for comparison with the similar parts of L. 

 Hageni and proxima.
