SUBORDER MALLOPHAGA. 219 
_ female, curved, the inner convex margin approximate, the outer concave portion 
inclosing near the front an oval spot. Approaches intermedius Piaget, which is 
described from Halietus vocifer. It differs from that species in having the clypeus 
more emarginate for the transparent portion, the dense portion narrower at tip. The 
genital hooks are decidedly hooked, the genital patch of male heavier and the 
posterior portion broader. The genital spots of female approach closely to pattern 
of platystomus. 
From bald eagle (Halietus leucocephalus) collected by Dr. C. M. 
Weed, in Florida. 
Docophorus bubonis n. sp. 
General appearance of D. ceblebrachys, from which it differs distinctly in form of 
head and genital hooks, and in eyes being very obscure. Head oval, narrowing 
from eyes to occiput, broadest at base of trabeculz, contracting sharply to front; 
_ eyes very obscure or wanting, scarcely any convexity indicating their position, and 
_ no trace of pigment beneath. Occiput slightly curved, temporal lobes narrow, long, 
contracted posteriorly ; median space between occipital bands narrow behind; anten- 
ne situated slightly in front of middle. Trabeculze small and rigid, as in ceble- 
brachys. A very short hair at each side of transparent portion of front, a longer 
hair at middle.of external clypeus band, and two hairs on margin of temporal lobe. 
Prothorax short, metathorax broader than basal segment of abdomen. Abdomen 
widest behind middle at fourth and fifth segment. Light yellow bands, extending 
more than half way to middle disk, hairy, seventh segment with dorsal margin. 
Male genital hooks prominent, long, heavy, sharply curved at top. 
Two specimens, male and female, in Cassino collection, from Bubo 
virginianus, Pennsylvania. This is a well-marked species, although 
showing decided affinities to ceblebrachys. Theform of head in narrow- 
ness aud length behind the antenne will distinguish it from almost any 
described species, the reduction of the eyes is very marked, and the 
form of the genital hooks give it well-established characters. In form 
of head and rigidity of trabecule it approaches Nirmus, but the charac- 
ter of the clypeus and the general form of 
body, as well as its evident relationship to 
ceblebrachys, would prevent its reference to 
that genus.
