254 THE CANADIAN ENTOMOLOGIST 



Dolophilus. 



Fork 1 reaches to discal cell; hind tibiae of male very hairy; 

 in female the tip of abdomen forms a long ovipositor; in our 

 species the discal cell is not angulate above. 



I have two species of this genus as defined above; the charac- 

 ters used to distinguish the European species from Philopotamus 

 do not apply to our forms. 



Dolophilus major, n. sp. (Fig. 66). 



Black, with black and golden-yellow hair; golden hair on front 

 of vertex and base of thorax; palpi brown, antennae dark, annu- 

 late with black, coxa and femora rather dark, rest of legs paler; 

 abdomen black; wings black; fore wing beautifully spotted with 

 golden hair, spots rather small, and mostly subequal in size and 

 situate in the cells, each apical cell with four to ten of them, all 

 over wings; hind wings blackish. Wings long, fork 1 reaches to 

 the discal cell, fork 2 is its width on discal cell, fork 4 a little be- 

 fore fork 3, both long, discal cell nearly three times as long as 

 broad; hind wings with forks 1 and 2 very narrow, as long as in 

 the fore wings. 



Expanse 22 mm. 



From Black Mt., north fork of the Swannanoa River, N. Car., 

 May. I have no female, and its large size seems out of place in 

 this genus, but the genitalia and long fork 1 will not fit in 

 Philopotamus. 



Dolophilus breviatus, n. sp. (Fig. 61). 



Face dark; antennae brown, annulate with yellowish; palpi 

 brown; gray hair between antennae, and on vertex and thorax, a 

 tuft of black hair near each eye; abdomen brownish; legs yellowish, 

 brownish on tarsi; hind tibiae with much long pale hair. Wings 

 dark, densely irrorate with golden, a large golden spot before and 

 one beyond stigma, costal area interrupted once with golden; the 

 golden on wing is so dense a reticulation that the dark appears to 

 be broken into many little rectangles; hind wings gray, blackish at 

 tip. Fork 1 reaches to discal cell in both wings, in fore wings 

 forks 3 and 4 subequal, in hind wing fork 3 is much longer than 

 pedicel; the third joint of maxillary palpi much longer than fourth; 

 in female there is a long yellowish ovipositor.
