apparently not different from those of typical nubicus. The aberrant 
$ $ mentioned under cheopis, possibly belong to these . The 
material is not extensive enough to enable us to decide whether these 
specimens are merely large individuals of nubicus, or whether they 
represent a distinct species. The relatively broad hindcoxa they share 
with chersinus. In the latter insect, however, the first midtarsal 
segment is much shorter. 
(9) Loemopsylla chersinus Rothsch. (1906). 
(PI. Ill, fig. 5; V, fig. 5.) 
Pulex chersinus Rothschild (1906 a , p. 75, t. 4, fig. 1—3, Khartoum, off Jaculus 
gordoni). 
Closely allied to L. nubicus and cheopis. The subapical bristle of 
the seventh abdominal tergite is as long as the second hindtarsal 
segment. The hindcoxa is broader than in the allied species, bearing 
a comb of five spines. The first midtarsal segment is short, being only 
two-thirds the length of the second (PI. Ill, fig. 5). The genitalia 
resemble those of nubicus ; but the most proximal bristle of the broader 
process is situated much nearer the apex (PL V, fig. 5). 
We have only one (the type) found on Jaculus gordoni at 
Khartoum by Dr A. Balfour. 
(10) Loemopsylla nesiotes spec. nov. 
(PI. Ill, fig. 3 ; VI, fig. 4.) 
Larger than L. nubicus ; the bristles of the tibiae and tarsi much 
stouter and shorter. 
Head. The rostrum reaches to the trochanter. The first segment 
of the maxillary palpus equals the third, the proportions of the four 
segments being 14 to 16, 18 to 19, 14 to 16, and 24. 
The first antennal segment of the </ bears 4 minute hairs at the 
hind edge, a transverse row of 7 or 8, and proximally to this row 1 or 2 
additional hairs. Above the antennal groove there are, in 15 or 16 
small hairs. 
Thorax. The pronotum bears, on the two sides together, 13 to 15 
bristles, the mesonotum 13 or 14, and the metanotum 12 to 14. There 
are usually 5 bristles on the pleura of the mesosternite, but occa¬ 
sionally only 4. The episternum of the metathorax bears 12 to 14 
bristles arranged in two rows (6 to 9, 5 to 6).
