4 b Canadian Arctic Expedition, 1913-18 



Anabolia em^rginata, n. sp. 



Black with black bristles, some yellowish bristles on vertex and thoraTx; 

 antennae narrowly annulate with pale; legs yellowish brown, spines black. 

 Fore-wings blackish, outer and posterior portions with scattered small pale 

 spots, a distinct whitish hyahne spot over the thrydium and one below it near 

 the end of the anal vein; the hind wings are grejdsh, darker on the anterior tip; 

 genitalia dark. Venation much as in A. nigricula but the wing is rather shorter 

 so that the apical cells are noticeably shorter than in that species. Male geni- 

 talia, seen from above show two upper appendages close together, each with 

 an excised tip; from the side the lower appendage is seen to be tipped with 

 two little black teeth. In general similar to A. nigricula but the shape of the 

 superior appendages is different, and they Are shorter than in that species.

Two males from Teller, Alaska, July 29, 1913 (F. Johansen, coll.) Type 

 in Canadian National Collection of Insects, Ottawa, paratype in Museum of 

 Comparative Zoology, Cambridge, Mass. 



Limnephilus, sp. 



One female from Nome, Alaska, August 21, 1916 (F. Johansen, coll.) may 

 be the female of L. harrimani Bks., known only from the male . L. harrimani is 

 closely related to L. sitchensis, and so is this form. The body is greyish brown; 

 vertex and thoracic vittae dull black, latter separated by a grey streak; vertex 

 between lateral ocelli and eyes grey pollinose ; palpi, antennae and legs yellowish, 

 latter with black spines, basal joints of antennae dark; genitalia pale. Fore 

 wings yellowish brown, marked with darker brown and whitish hyaline much 

 as in L. sHchensis; an oblique mark across the thyridial cell, and a large area 

 each side of the anastomosis hyaline, this spot extends over bases of apical and 

 first subapical cells and the tips of discal and thyridial cells. The dark brown 

 is mostly on the posterior part, and along the veins; veins pale, anastomosis and 

 lower stigmal vein darker; hind wings grey hyahne, veins pale. Face with 

 yellowish hair in the middle and black on the sides, vertex, pronotum and meso- 

 notum mostly with yellowish hair; some macrochatae on vertex dark. Fore 

 wings have the shape of L. sitchensis; the discal cell is plainly longer than its 

 pedicel; the first apical is wider at base than the second, the fourth is about 

 one-third as wide at base as the third or fifth ; in the hind wings the fourth apical 

 cell is slightly pedicellate. The superior appendages of the female are very 

 long, slender, and divaricate, longer than in L. sitchensis, the inferior appendage 

 is much shorter than in that species. 



Expanse, 29 mm. 



Note. — The collection also included a number of immature stages of Neuroptefoids, the identifica- 

 tion of which was not possible.
