ANOPLURA AND MALLOPHAGA FROM AFRICAN HOSTS. 
By V. L. KeLtLtoce ann J. H. Paine, 
Stanford University, California, 
(PLateEs IV and V). 
The descriptions of new, and determinations of old, species of Anoplura and 
Mallophaga presented in this paper are based on a small collection of these 
ecto-parasitic insects taken from mammals and birds of the Egyptian Sudan and 
other North and West African localities. The collection was made by various 
collectors, as indicated for each species, and was submitted to us by Mr. Guy A. K. 
Marshall, Scientific Secretary of the Entomological Research Committee 
(Tropical Africa) of the British Colonial Office. 
ANOPLURA. 
Pediculis capitis, De Geer. 
Specimens from the head of a man (Dinka), near Bor, Egyptian Sudan 
(H. H. King); also specimens from the loin-cloth of a woman (Dinka), Azzar, 
near Bor, Egyptian Sudan (77. HZ. King). 
Hematopinus asini (Linn.) Stephens. 
From horse, Khar Altar, Angelo, Egyptian Sudan (/7. HI. King). 
Hematopinus peristictus, sp. n. (Pl. IV, figs. 3 and 6). 
Males and females from several wart-hogs (Phacochoerus ethiopicus), Akamanga, 
North Nyasa (Dr. J. B. Davey), and from a_bush-pig (Potamochoerus 
choeropotamus) Fort Hill, North Nyasa (Dr. J. B. Davey). 
This striking new Hematopinus shows similarities with H, sus (Linn.) Leach, 
the common louse of swine, but ditfers markedly in its short head, the reduced 
character of its ocular projections, and the arrangement of its markings. 
FremaLe.—Length, 5 mm.: width, 3 mm. General colour yellowish brown, 
with distinct darker (brown to blackish brown) markings on head, thorax, legs 
and abdomen. //cead short, as wide as long (in this character differing much 
from H,. suis, which has a narrow head, twice as long as wide). Ocular 
projections slight and blunt. A blackish brown transverse band across the front 
of the head, and small blackish brown blotches bordering the front of the ocular 
projections. Thorax sub-pentangular, with curving lateral margins and straight 
anterior and posterior margins. Strongly patterned with blackish brown bars 
irregularly radiating from a central spot (PI. IV, fig. 3). Legs very heavy and 
strong, the tibie larger than the femora; with strong blackish brown bands 
and blotches, as shown in the figure. dddomen three-fourths as wide as long and 
with the swollen, rounded margins of the segments projecting laterally, although 
there is only one inter-segmental suture which is distinct (on dorsal surface)
