Pulex witherbyi , Rothschild (1903, p. 86, n. 6, t. 1, figs. 2, 5, 6, t. 2, figs. 11,15, White 
Nile and Shendi, off Erinaceus albiventris, etc.). 
The insect recorded by Baker (1895, p. 66) from Socotra may possibly not be this 
species. 
Head. The rostrum reaches beyond the apex of the forecoxa. The 
first segment of the maxillary palpus is a little longer than the third, 
and the second longer than the fourth. The most ventral bristle of the 
subapical row of the occiput is placed far apart from the next one, the 
second, or the second and the third, bristle being absent or replaced by 
a small hair. The first segment of the antenna of the bears 6 hairs 
along the hinder edge and an oblique row of about 7 across the segment 
ending at the anterior apical corner. In the $ the apical projection of 
the first antennal segment bears 2 hairs. 
Thorax. The tergites bear 9 to 11 bristles on the two sides together. 
The pleura of the prosternite is pointed behind. The mesosternite bears 
3 bristles. The internal rod of this plate, extending from the insertion 
of the coxa upwards, ends dorsally at the anterior corner of the sclerite, 
the portion of the plate situated in front of the rod being very narrow 
(side-view, see diagram, p. 25). The episternum of the metathorax is 
completely fused with the sternum, and of nearly the same size (lateral 
view), the line of separation being indicated posteriorly at the meral 
suture (which separates the epimerum from the sternum and episternum). 
There is one long bristle on the episternum, while the sternum bears 
only a small hair or no hair at all. The epimerum has two rows of 
bristles, the numbers being in </ 3 and 4, and in $ 4 or 5, and 4. 
Abdomen. The first tergite bears an antemedian and a postmedian 
row of 4 (</) or 5 ($) bristles, there being also some minute hairs on 
the side between the two rows. The second to fourth tergites in $ 
usually bear 10 bristles on the two sides taken together, but sometimes 
only 8, in the the number being 9 or 10. On the fifth and sixth 
tergites there are 8 bristles in the $ and 8 or 9 in the </, while the 
seventh tergite has 6 bristles, two on each side being placed ventral to 
3—2
