Modified segments. </• The eighth sternite (PI. IV, fig. 9) bears 
5 to 7 short bristles, 2 of them being placed near the apical margin. 
The clasper bears three processes, the central one being the narrowest, 
and the ventral one the shortest. The manubrium (M) is short, being 
about as long as (or even shorter than) the distance from its base to the 
tip of the longest process. The ninth sternite is narrow, and bent at 
the top into a short hook. The internal plate (endopodite) of the penis is 
broad, the apex being rounded off, with the upper corner remaining almost 
rectangular. The external part of the penis has the brush-like organ 
more strongly developed than that of any other species of Loemopsylla. 
— $. The apical edge of the eighth tergite (PI. V, fig. 8) is nearly straight, 
bearing a row of bristles as shown in the figure, there being, besides, on 
the outer surface one long bristle on a level with the uppermost apical 
one and 2 or 3 on a level with the ventral apical bristles.

The junior author found this species rather commonly on various 
hosts in Egypt and the Egyptian Sudan. We have a long series from 
the following localities and hosts: 
Egypt, off Viverra ichneumon ( J 1 and $, cotypes, received from the 
Berlin Museum). 
Shendi, Egyptian Sudan, off Erinaceus aethiopicus, Vulpes niloticus 
and Hyaena hyaena. 
Gebel Auli, White Nile, off Erinaceus albiventris (collected by 
H. F. Witherby). 
Kerma, Dongola, off Gerbillus pygargus and Vulpes vulpes aethio¬ 
picus. 
Cairo, off Erinaceus auritus. 
Zaghig, Natron Valley, Lower Egypt, off Erinaceus auritus and 
Canis zerda. 
Der Macarius, Natron Valley, Lower Egypt, off Vulpes famelica. 
Karo Lola, Garre Livin country, South Somaliland, off Erinaceus 
albiventris (collected by Baron Carlo von Erlanger). 
(2) Loemopsylla somalicus spec. nov. 
(PI. Ill, fig. 8.) 
This insect is closely allied to L. pallidus, differing, however, in the 
much smaller number of bristles. 
Head. The subapical row of bristles of the occiput is represented 
on each side by a long ventral bristle and a small dorsal one, besides
