Abdomen. The first tergite has an irregular median row of 
10 bristles and a postmedian row of 6 to 8 in the and 10 in the $, 
on both sides together, there being some additional bristles on the back. 
The numbers of bristles on the second to seventh tergites are in the 
20, 20, 17 to 19, 17, 15 to 17, 14, and in the ? 22, 20 to 22, 20 to 22, 
19 to 21, 19 or 20, 16 or 17. The subapical bristle of the seventh 
tergite is considerably longer than the second midtarsal segment. The 
bristles on the sternites are in the </ 2 on the basal one and 4 on the 
others, in the ? also 2 on the basal sternite and 6 to 8 on the others. 
Legs. The forecoxa bears about 30 bristles. The hindcoxa (PI. II, 
fig. 14) is much more rounded than in the allied species, bearing 
posteriorly 2 subapical bristles. The bristles of the tibiae and hindtarsi 
are long. The longest apical bristle of the second hindtarsal segment 
reaches far beyond the apex of the fifth segment, a second bristle on the 
same side extending to the apex of this segment, while a bristle on 
the anterior side of the second segment reaches at least to the centre 
of the fifth. This latter segment, in the </> is as long as the 
second midtarsal one, while in the $ it is shorter than that segment. 
Modified segments. </. The eighth sternite bears one long bristle 
on the lateral surface and 2 to 4 along the ventral margin. The clasper 
(PL IV, fig. 10) has two free processes, one being long and rather 
broad, bearing a number of long bristles, the other being slender. The 
ninth sternite resembles that of L. mycerini .— $. The eighth tergite 
(PL V, fig. 7) has an apical row of 7 to 9 bristles on the outside and of 
7 or 8 on the inside, there being also from 3 to 5 lateral bristles on the 
outer surface. The anal sternite is acuminate.

We have specimens of both sexes from Lahaj, north of Aden, off 
Meriones rex, collected by Baron Carlo von Erlanger and O. Neumann on 
21st December, 1899. 
(23) Loemopsylla conformis Wagn. (1903). 
Pulex pallidus Wagner (1894, p. 440, non Taschenberg, 1880, err. ident.). 
Pulex conformis Wagner (1903, p. 508, n. 2, Transcaspia, off a small owl); Baker 
(1905 a, p. 141). 
This insect is not known to us from specimens. It possibly may be 
the same as L. ramesis. The chief characters given by Dr Wagner are 
as follows: 
The rostrum falls considerably short of reaching to the apex of the 
forecoxa. The lower angle of the eighth abdominal tergite of the $ is
