ANOPLURA FROM AFRICAN HOSTS. 

 By Bkuce F. Cummings. 



(Published by permission of the Trustees of the British Museum,) 



The following notes and descriptions are based on material received by the 

 Entomological Research Committee, who have kindly presented the types of the 

 new species to the National Collection. 



Genus Scipio, nov. 



Type : Haematopinus aulacodi, Neumann (Archives de Parasitologic, 1911, 

 p. 403). 



Head long and broad, the 3rd joint of the antenna very long, almost equal to 

 the length of the 2nd, 4th and 5th together. Thorax shorter and broader than 

 the head. First pair of legs with a long slender claw and, arising close beside 

 it, another claw, half the length of the first, hook-shaped and enlarged at its 

 base. The pretarsal sclerite of the 2nd and 3rd pairs of legs very large. 

 Abdomen ovoid, as long as head and thorax together ; pleurae small but strong, 

 the posterior ones drawn out into tubular processes as in Solenopotes. 



The foregoing diagnosis is based on two specimens of S. aulacodi, rf and Q , 

 off Thryonomys swinderianus, Temminck, from Chirimanyama stream, Luangwa 

 Valley, North-Eastern Rhodesia (S. A. Neave 11. ix. 1910). The c? is much 

 smaller than the Q , with the terminal segment of the abdomen rounded. 



Genus Neohaematopinus, Mjoberg. 



Arkiv. for Zoologi, VI, 1910, p. 160. 



This is Mjoberg's genus for Haematopinus sciuropteri, Osborn (Bull. 5, U.S. 

 Dept. Agric. 1896, p. 182). Immediately succeeding his diagnosis of this genus 

 Mjoberg proposes another new genus, Acanthopinus, for a species, A. sciurinus 

 (from Sciurus vulpinus), in which the basal joint of the antennae in both $ and 

 Q is very thick and runs out at the distal postaxial corner into a strong spinous 

 projection. But unlike Neohaematopinus, the 3rd joint in the $ of Acanthopinus 

 does not run out preaxially into a strong prominence. Some Anoplura from 

 Helio sciurus palliatus, Peters, (British East Africa) are closely allied to both 

 these species and in the form of the antennae combine the characters of the 1st 

 joint in Acanthopinus with those of the 3rd joint of Neohaematopinus. Mjoberg's 

 second genus ought therefore to be sunk and the new species is described below 

 under Neohaematopinus. Neumann's species, Haematopinus echinatus (Arch. 

 Parasit., April, 1910, p. 518) should also be included in this genus. 



Neohaematopinus heliosciuri, sp. nov. (fig. l). 



Head a little longer than broad, the anterior border broad, very slightly convex, 

 projecting but little in front of the antennae. Lateral margins expanding a little at
