proximally to this row another composed of smaller bristles. Along- 
the apical edge of the eighth tergite there is a row of about a dozen 
bristles on the outside, the inside bearing two rows of smaller but 
rather stout bristles.

bennettii, collected by J. A. Wolffsohn. 
7. Genus : Coptopsylla gen. nov. 
Head. Frons truncate (PI. II, fig. 4); no distinct tubercle above the 
truncate part. Antennal groove open, the genal process being very 
short; no distinct internal incrassation from the base of the groove to 
the vertex ($). Club of antenna long, segmented all round as in 
Parapsyllus. Labial palpus very long, consisting of 5 segments. No 
bristles beneath the eye at the edge of the genal process. 
Thorax. One row of bristles on the tergites; the mesonotum bearing- 
some long thin spines before the apex. Epimerum of mesothorax 
nearly horizontal, covering the stigma. Sternum of metathorax long in 
a dorso-ventral direction. 
Abdomen. Tergites with one row of bristles, except the first, 
which bears two; seventh tergite with a long and a short bristle on a 
tubercle placed at the apical edge, the latter being excised where the 
tubercle is placed; the edge between the tubercles of the two sides 
produced backwards. There are two receptacula seminis as in Hystricho- 
psylla and Macropsylla. 
Legs. Internal rod-like incrassation of midcoxa forked below middle. 
Hindcoxa without comb, excised posteriorly before apex, the angle dis¬ 
tinct. First fore- and midtarsal segment shorter than second. Fifth 
tarsal segment with 5 lateral bristles. 
Modified segments. $ . Eighth abdominal tergite bearing some 
hairs above the stigma. Stylet with an apical bristle and a short one 
before apex situated in a notch. The </ not known to us. 
Type of genus: Pulex lamellifer Wagner (1895). The genus 
contains only one species. It is nearly related to Parapsyllus, but can 
easily be recognised by the truncate frons, the 5 lateral bristles 
on the fifth tarsal segment, and the double receptaculum seminis.
