Borens gracilis n. sp. 
Female : length, 5 mm. ; wings, legs, ovipositor very dark 
brown, almost black; eyes and rest of body black; white 
pilosity on body somewhat longer than that of calif ornicus, 
but nearly absent on abdominal terga; pronotum with two

of the eye; ovipositor one and one-half times the length of 
the rostrum ; fore wing pads small, not entirely covering the 
hind wing scar, the posterior half of which is visible from 
above. Male unknown. 
Holotype ( $ ) : collected between Kennecott and McCar- 
thy, Alaska, April 15, 1934 (W. L. Lloyd) ; in Washington 
State Museum. 
Paratype : 1 $ , with same locality data as holotype ; in 
Museum of Comparative Zoology. 
The specimens on which this species is based were deter- 
mined by Lloyd (1934) as unicolor Hine. They are excluded 
from this species, however, by the difference in the lengths 
of the rostrum and the ovipositor, as well as by the partially 
reduced fore wing pads, a characteristic which is not shared 
by any other of our Boreus.
