ANOPLURA AND MALLOPHAGA FROM AFRICAN HOSTS. 

 By V. L. Kellogg and J. H. Paine, 



Stanford University, California, 



(Plates 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 Reseai-ch 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. II. K/nq) ; also specimens from the loin-cloth of a woman (Dinka), Azzar, 

 near Bor, Egyptian Sudan (//. H. King). 



Hgematopinus asini (Linn.) Stephens. 



From horse, Khar Altar, Angelo, Egyptian Sudan {H. II. King). 



Hsematopinus peristictus, sp. n. (PL IV, figs. 3 and 6). 



Males and females from several wart-hogs {Phacochoerus (Bthiopicns), Akamanga, 

 North Nyasa (Dr. J. B. Davey), and from a bush-pig {PotamochocrHs 

 choeropotamus) Fort Hill, North Nyasa {Dr. J. B. Davey). 



This striking new Hamatopinus shows similarities with H. suis (Linn.) Leach, 

 the common louse of swine, but diifers markedly in its short head, the reduced 

 character of its ocular projections, and the arrangement of its markings. 



Female. — Length, 5 mm. : width, 3 mm. General colour yellowish brown, 

 with distinct darker (brown to blackish brown) markings on head, thorax, legs 

 and abdomen. Head 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 tibiaj larger than the femora ; with strong blacldsh brown bands 

 and blotches, as shown in the figure. Abdomen 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)
