the fourth or base of the fifth segment, the longest bristle of the 
anterior side reaching only to the apex of the third segment. The 
fifth segment in the fore- and midtarsi of the f has 3 ventral 
apical spine-like bristles, the central one being the longest, the lateral 
ones being short and very stout. In the % this segment lias, in 
contradistinction ro the </> one long and one short bristle. 
Modified segments. f . The eighth sternite bears about 22 
bristles on each side. The clasper (PI. V, fig. 1) has a short and a long 
process, the short one bearing some very stout bristles. The ninth 
sternite is stouter than is usual in this genus, the apex being hairy. 
The internal plate of the penis is pointed, the external plate becoming 
more and more acuminate towards the apex.— $. The eighth tergite 
(PL V, fig. 9) has an external apical row of 10 to 12 bristles and 
an internal apical row of 10 short ones; there is, on the external 
surface also, a row of 8 to 10 bristles extending from the stigma 
downwards, 2 long bristles standing in between the lateral and 
apical rows.

A South African species, of which we have a series of both sexes as 
follows: Umfolozi Station, Zululand, taken in July and September 
1904, off Saccostomus campestris, and also off Mus auricomis, Sep¬ 
tember 1904; Beira, Portuguese East Africa, February 1907, off 
Cricetomys gambianus ; all collected by C. H. B. Grant. 
(14) Loemopsylla tortus spec. nov. 
(PI. V, fig. 4.) 
Very closely allied to the preceding species. Both sexes, however, 
are larger. The hindfemur bears 3 subventral bristles on the outer 
side before the apex. The bristles situated at the apex of the hindtibia 
are longer than in L. scopulifer, the longest bristle reaching in the </ to 
the apex of the first hindtarsal segment and in the $ to the subapical 
notch of the same. The seventh abdominal sternite of the ^ bears 
only 6 to 8 bristles in front of the postmedian row of bristles. The 
larger process of the clasper of the </ (PI. V, fig. 4) has 6 bristles as 
in L. scopulifer, but these bristles are shorter and much thinner than in 
that species. The second process of the clasper is narrowed towards 
the apex and gradually curved upwards. The largest bristle of the 
anal tergite of the <f is longer than in scopulifer, as are also the 
bristles situated on the eighth sternite.
