fossae large; antenna with first segment more than half as broad as 
long, appendage of third segment longer than last segment; eye large, 
convex; color pale golden brown, antennal and occipital bands, man- 
dibles and a blotch on signature, darker. 
Prothorax at base one-half as broad as head, sides nearly straight, 
diverging from front to rear, a strong bristle at posterior angles, pos- 
terior margin rounded; color light, golden brown, darker at sides, 
coxae showing through as darker blotches. Metathorax short, dorsum 
not longer than prothorax, sides strongly rounded, margin with two 
long, pustulated hairs at one-third distance from apex, posterior mar- 
gin obtusely angled; color same as prothorax. Legs concolorous with 
body, femora thick. 
Abdomen about equal in length to rest of body, broadly truncate, 
at apex, segments 3, 4 and 5 broadest; lateral margin of first segment 
nearly twice as long as that of second segment; marginal angle of the 
first two segments with a single long hair, of segments 3, 4 and 5 with 
two, of segments 6 and 7 with three; dorsum with scattered fine, long 
hairs; color pale golden brown, a longitudinal dorsal darker blotch, and 
each segment with a well-marked light marginal blotch which curves 
strongly inward in the anterior part of segment. 
Female. Body—length 2.40 mm.; width 1.1 mm.; head, length .72 
mm.; width .86 mm.; abdomen longer in proportion to rest of body 
than in male; the markings are similar to those of the male, but more 
pronounced. 
Lipeurus protervus Kellogg. 
A female of this curious species, taken on Lagopus lagopus, 
Norton Sound. 
Lipeurus parviceps Piaget. 
Two specimens referable to this species from the eider 
duck, Arctonetta fischeri, Duck Egg Island. Lipeurus parvt- 
ceps has been recorded hitherto only from Sterna. Our spec- 
imens differ from Piaget’s figure, in having larger pustules in 
the dorsal blotches, and only one dark spot on the metathor- 
acic margin. Probably our specimens should be considered 
to be a variety. 
Colpocephalum morsitans sp. nov. (Fig. 3). 
One male from Tringa maculata, Norton Sound. This 
species is close to bicolor of Piaget from Strepsilas interpres. 
It can be distinguished from that species by the abdominal
