﻿BRUCE F. CUMM1NGS — ANOPLURA FROM AFRICAN HOSTS. 395 



with a sense organ at the distal lower corner ; apical joint shorter, with its sense- 

 organ half-waj along the lower side. In the Q , the 3rd joint approximating in 

 length to the penultimate, which is scarcely pedunculate. Thorax narrow in 

 front, broadening towards the abdomen, posterior margin slightly concave, meta- 

 thorax short. A spine on each " shoulder " and two in line obliquely with the 

 spiracle. Sternal plate broad and long, the base truncate in the middle, con- 

 cavely oblique at each side of the base, rounded in front. Legs : first pair small, 

 coxae approximated, claw narrow and slender ; posterior pairs longer, stouter, with 

 larger claws. Abdomen long, parallel-sided in the cf? longer in the Q and 

 narrowing after the middle. Terminal segment of c? conical, of Q truncate. On 

 the upper surface of the cf segment I is small, with six hairs, two on each side 

 and two in the middle ; II with two rows of hairs, 8 in the first row and 11 

 in the second, the three outside hairs in the latter close together and mounted on 

 a slight projection ; succeeding segments with one row each o£ closely spaced 

 hairs ; VIII bare, telson conical, with a fairly long hair on the margin at the base 

 on each side, followed by a series of small hairs around the border. In the Q , 

 on the upper surface, segment II without the lateral projections ; succeeding 

 segments with three rows of widely and equally spaced broad hairs ; penultimate 

 segment with two rows ; terminal segment with one semicircular row. On the 

 under surface of the c?, segment I bare, II with two rows of hairs, III with three, 

 succeeding segments with two rows of widely spaced hairs, YII with one row of 

 four stout hairs, VIII with only two long hairs, telson with four hairs, two sub- 

 terminal and two further forward. On the under surface of the Q , segment II 

 with one row, the succeeding segments with three rows of hairs, VII with two 

 rows and VIII with only one row. Gonopods each with three stout hairs on the 

 outside ; anterior lip of the vulva with a serrate edge. Pleurae broad rect- 

 angular, except the 8th in the cT ? which is oval and projects almost as far as the 

 end of the abdomen. Each pleura with two bristles at the lower margin ; on 

 the 7th and 8th of the S these are abnormally long. Terminal pleurae of Q 

 each with a spine and a group of thick bristles.

In the presence of a transverse suture behind the head and in the large claws 

 of the hind pairs of legs, this species stands close to P. svturalis (Osborn) 

 (Bull. 5, N.S., U.S. Dept. Agric, 1896, p. 185). It is distinguished by its 

 larger size, the long-oval shape of the abdomen and by many other minor 

 features. 



Q . Head oval, rounded in front, broadening somewhat behind the antennae, 

 the occipital area entering a V- sna ped groove in the thorax. A transverse row 

 of four hairs on the upper surface in front of the antennae and immediately in
