3. Genus: Moeopsylla Rotlisch. (1908). 
Moeopsylla Rothschild (1908, p. 3). 
Very closely allied to Loemopsylla and Pariodontis, but differs in 
the following characters: 
Head. Frons with a minute tubercle situated close to the suture 
which separates the frons from the occiput. The genal edge dilated into 
a tooth as in the Sarcopsyllidae, Lycopsylla, and Pariodontis (PI. II, 
fig. 13). The segmentation of the rostrum distinct only on the anterior 
side. 
Thorax. Bristles of the pronotum nearer to the base than to the 
apex. Metanotum much longer than the mesonotum. Mesosternite 
narrow, the internal rod-like incrassation, which extends from the 
insertion of the coxa upwards, ending at the anterior margin of the 
sternite instead of at the dorsal margin (PI. II, fig. 13). 
Legs. Hindcoxa with a patch (not a row) of very numerous short 
spines on the inner surface. Basal tooth of the claws very small. 
One species from Africa.

Moeopsylla sjoestedti Rothsch. (1908, p. 3, t. 1, figs. 1—4). 
Professor Y. Sjoestedt found a small series of both sexes of this 
species on Phacochoerus africanus in the Massaisteppe, German East 
Africa, on the 9th October 1905. 
4. Genus: Loemopsylla gen. nov. 
Head. Frons without a notch or tubercle (PI. I). Genal process 
almost completely closing the antennal groove, separating it from the 
prosternum and being pointed behind. Antenna different in the 
sexes, the first segment being long in the and short in the $ ; the 
second, transverse segment bearing a number of long bristles at the 
apical edge. The first segment of the club compressed and leaf-shaped ; 
the globular or slightly elongate club appearing solid on the anterior 
side, the incisions between the segments being hardly at all indicated, 
while on the hinder side the first two or three segments are deeply 
separated from one another (PI. II, fig. 5). On the anterior side of the 
club there are from two to five very short hairs. Antennal groove in $ not
