narrowed, portion being longer. The rostrum is longer than the 
maxillary palpi, reaching to the apical third of the forecoxa. 
Thorax. The three thoracical tergites bear, on the two sides 
together, 14, 10 or 12, and 12 bristles respectively. There are 6 bristles 
on the pleura of the mesothorax, while the epimerum of the metathorax 
bears 10 or 11 bristles in two rows (5 to 7, 4 or 5). 
Abdomen. The first tergite bears two rows of bristles, the first row 
consisting of 5 to 7, and the second of 6 bristles. The rows of bristles 
on the second to sixth tergites extend much further down the sides than 
in the other species of Loemopsylla, their number being in the </ 14 to 16, 
in the $ 18 to 20, on the two sides together, the seventh tergite having 
10 to 11 bristles. The dorsal subapical bristle of this tergite is longer 
than the first and second midtarsal segments together. On the sternites 
there are in the </ 4 bristles, in the $ 8, the basal sternite having 
only 2 bristles in both sexes. The ventral line of this sternite is, in 
side-view, more oblique proximally than in the other species, being 
rather sharply curved near the apex. 
Legs. The forecoxa bears about 30 bristles. The midcoxa is very 
strongly rounded behind, being almost as broad as it is long. The hind- 
coxa is likewise rounded and broad, bearing a comb of 4 to 6 spines. 
The mid- and hindfemora have on the outside 2 (occasionally 3) 
ventral subapical bristles and one lateral subapical one, there being only 
one bristle on the inside, the usual lateral row of bristles being absent. 
The hindfemur, moreover, has a very characteristic shape (PI. II, fig. 7), 
its widest point lying further back than in the other species of Loemo¬ 
psylla. The hindtibia bears a lateral row of 6 to 7 .bristles and 2 
additional ones in between this row and the dorsal bristles. The tarsi 
bear more bristles on the outer surface than in the other species of 
Loemopsylla. The longest apical bristle of the second hindtarsal segment 
reaches just beyond the apex of the fourth segment. While the first 
hindtarsal segment of the other species of Loemopsylla bears 5 to 7 
bristles close together on the inside at the apex (see PI. I), in chephrenis 
one bristle only exists in their place. The first pair of lateral bristles of 
the fifth foretarsal segment is placed nearer the mesial line than the 
other bristles. This segment bears in the g 3 short stout apical ventral 
bristles; in the 2 it has 2 apical bristles instead, one on each side, both 
being rather thin, the fifth segment of the mid- and hindtarsi bearing in 
both sexes only 2 such bristles. 
Modified segments. </. The eighth sternite bears on each side one 
lateral and two ventral bristles. The clasper has two free slender pro-
