218 INSECTS AFFECTING DOMESTIC ANIMALS. 
Docophorus rostratus Nitzsch. 
Docophorus rostratus; Burmeister, Handbuch, Vol. II, p. 427; Denny, p. 87, Pl. TT, fig.4; Giebel, 
p. 76, Pl. X, fig. 4; Piaget, p. 27, Pl. I, fig. 7. 
A specimen of this well-marked species from the barn owl (Strix 
pratincola) in the collection of Prof. Lawrence Bruner. There is no 
difference of note between this and the European form as described, 
though it is perhaps a little more slender and elongate than the figures 
would indicate. Even this is possibly due to extension of abdomen from 
pressure of cover glass in mounting. 
Docophorus melanocephalus Burm. 
In Burnett collection. Great Cayenne tern. Recorded by Kellogg, 
New Mallophaga, p. 99, on royal tern (Sterna maxima), Monterey, Cal. 
Docophorus buteonis Pack. 
Packard, Am: Naturalist. Vol. lV, p. 93, Pl. I, fig. 3. 
Packard’s description of this species seems not to have been accessi- 
ble to Piaget, or he was unable to verify it, as he passes it with a mere 
mention. (Les Pédic., p. 22.) 
Ihave specimens from buteo lineatus, the hawk from which Packard 
described the species, sent me by Dr. C. M. Weed, of Hanover, N. H., 
which agree entirely with Packard’s description, and they appear to me 
to be sufficiently distinct from other species to be retained. Packard’s 
description is as follows: 
The species of Docophorus figured on PI. I, fig. 3, appears to be undescribed, and 
may be called D. buteonis. It lives beneath the feathers of the red-shouldered 
hawk. It is honey yellow, and the abdomen is whitish with triangular chitinous 
plates on each segment, the two on the segment next to the last forming a continuous 
band. The head is longer than broad, with the trabeculie (or movable horny process 
just in front of the antenne) as long as the two basal joints of the antenn, and 
extending to the middle of the second joint. The basal joint of the antennz is rather 
thick, and the second joint is as long as the two terminal ones. 
Both description and figure are wanting in reference to characters 
which would most certainly distinguish the species, and I may add that 
the species is separated from platystomus by the deeper incision of 
the clypeus, and the more circular outline of the clear lateral dilation. 
The genital patches are approximate and the proximal margins of the 
patches denticulated ; the outer portion of the patches faint. 
A specimen in the Burnett collection from Tyrannus atra is referred 
here. 
Docophorus halieti n. sp. 
Head a little wider than long, clypeus tapering but with dilated apical portion 
emarginate infront. The transparent dilation but little in advance of antennal bands, 
but curving outward so as to show as a clear part atsides; emargination shallow and 
reaching inner portion. Trabeculze simple, bluntly pointed, antennez slender, eye 
prominent, clypeus and temporal borders with few short hairs, abdomen ovate in 
female, round in male, sparsely hairy above and below, thickest on disk above; all 
hairs rather short. Genital hooks, male sharply curved, between them several 
prominent teeth. Genitalspot male, large, distinct, the anterior lateral oval portion 
wide apart connected to central portion by inflated band; central portion broad, 
widening at middle incised by lateral border behind, the wider part with two 
hair insertions on posterior half, extending to tip of last segment. Genital spot
