^°^192o""] CLARK — NEW SPHINGIDAE 69 



Sphinx gordius borealis subsp. nov. 



Al. ant. long., d", 40 mm.; 9, 43 mm. Al. ant. lat., (J', 15 mm.; 9, 

 16 mm. Marg. ext., cT, 23 mm., 9 , 24 mm. 



Habitat. — Gull Lake, Muskoka, Ontario. One male and one female 

 in coll. B. Preston Clark. Also one male from each of the following locali- 

 ties: Winnipeg, Manitoba; Murray Bay, Quebec; Mount Desert, Maine. 



This evidently is a northern form of S. gordius, and it is 

 sufficiently strongly marked to deserve subspecific recognition. 

 The genitalia follow closely those of S. gordius, but the harpe of 

 this form is straighter-edged on one side. That of S. gordius 

 curves evenly to the apex from both sides. In general, horealis 

 is markedly darker, both above and beneath, than gordius. It 

 is gray where gordius is brown. The cilia of the fore wing are 

 more prominently white between the veins, and in the hind 

 wing they are more brightly and uniformly white than in the 

 typical form. 



Poliodes senegalensis sp. nov. 



Al. ant. long., cf, 25 mm.; 9, 23 mm. Al. ant. lat., cf, 9.5 mm.; 9, 

 10 mm. Marg. ext., c?, 12 mm.; 9, 11.5 mm. 



Habitat. — Kaolack, Senegal. One male and one female (type) in coll. 

 B. Preston Clark, received from Mr. H. Bureau, Paris, France. 



Antennae gray above, brown beneath. Head, thorax, and abdomen 

 above, light gray. Breast and abdomen beneath, brown. Mesothoracic 

 tegulae paler. Dark brown band at base of abdomen above. Lighter in 

 coloration and more distinctly marked than P. roseicornis. 



Fore wing above: Light gray. An S-shaped hne extends from a point 

 on costal margin, 6 mm. from the apex, curving first distally, strengthening, 

 and curving costally, reaching the inner margin 5 mm. from the wing base, 

 and extending slightly along the margin. A lighter-colored, wavy, faint 

 line, 1 mm. posterior to this one on the costal margin, runs roughly parallel 

 to it to the inner margin. Posterior to the first S-shaped line is a dark 

 brown, roughly triangular area, extending nearly to the hinder angle of the 

 inner margin, and with its apex on R3. Within this area is a light-colored 

 line, 3 mm. in length, extending apically and obUquely from a point midway 

 on the inner margin. Between the second postmedian line and the distal 

 margin is a third line, sharply marked, irregularly angled, extending from 

 a point 4 mm. from the apex toward the hinder angle, which it almost
