these rows. At the posterior edge of the antennal groove there is a row of about 
seven very small bristles, and in addition to these three long and one short bristles, 
with two shorter bristles on a level with the upper long one. There are three 
bristles on the hinder edge of the head. The prothorax bears three bristles just 
anterior to the comb, which consists of twenty teeth. The mesonotum bears a 
series of rather stout bristles at its basal edge, followed by a series of five more 
bristles, the series curving laterally frontal. The posterior edge of the mesonotum 
is produced at the apex into a long and a short spine, of the same colour as the rest 
of the mesonotum. The episternum + epimeron of the mesothorax bears on its 
lower portion three long bristles, one obliquely behind the other, further up there 
are four more arranged in pairs. The epimeron of the mesothorax bears seven 
bristles, three of these are arranged in a triangle. The second, third, fourth, and 
fifth abdominal tergites in both sexes bear a spine on each side at their posterior 
edges. In the females the tergites bear two rows of bristles, in the male, however, 
the anterior row is absent, or represented by one or two bristles only. The seventh 
tergite in the female bears one long and two shorter bristles on each side, apically 
on its posterior edge. In the male the more ventral and basal bristle is separated 
from the two others. The sternites in the males bear two bristles, and occasionally 
a third shorter one; in the females. there are four subapical bristles and a shorter 
one near the middle. On the seventh sternite in the female there are a few more 
hairs present. The tibize of the forelegs bear six pairs of bristles on their hinder 
edges, those of the middle and hind legs bear seven. Each pair of bristles is 
accompanied by a shorter bristle on the outer surface of the tibie. The femora 
bear ventrally one thin bristle near the joint with the tibie. Length 2:6mm. 
I have examined four specimens of this species from Petawrus 
australis, from Victoria. The type is in the British Museum. 
TYPHLOPSYLLA INGENS, sp. nov. (fig. 4).—The rostrum of the head is very long, 
reaching to the end of the coxe ; each segment bears some long hairs at its distal 
end. There are the two usual rows of hairs between the mouth and the antennal 
groove, and in addition to these there are numerous hairs, some of them very long, 
at and near the lower edge of the head. In the male there are some hairs on the 
dorsal portion of the head, between the antennal groove and the hinder edge. The 
antennal groove is bordered posteriorly by thin hairs, arranged in a double row of 
considerable length. In addition to these there isa row of long hairs, some oblique 
rows of shorter hairs, and a row of very long hairs near the hinder edge of the head. 
The pronotum bears a comb of thirty spines. The meso- and metanotum, the 
epimeron + episternum of the mesothorax are all covered with hairs. The meso- 
notum bears two long thin spines on each side. The tergites of the abdomen bear 
three rows of hairs, all the sternites the second (the actual first) inclusive, are all 
densely clothed with hairs on the ventral surface. The femora and tibie are 
covered with hairs, the bristles at the hinder edge of the tibie being strongly 
chitinised. The bristles at the apex of the anterior tibie are as long as the first 
and second tarsal joints; those of the middle tibiw are shorter, being about the 
length of the first and half the second tarsal joints, while those of the posterior 
tibie are only as long as the first tarsal joint. Length 4-2mm. 
This species was found on Bathyergus mavritimus in Cape Colony, 
by H. A. Spencer. The type is in the British Museum. 
PULEX MADAGASCARIENSIS, Sp. nov. (fig. 3).—The second joints of the labial 
palpi are twice as long as the third. There is a single large bristle before the 
antennal groove, and another above the mouth. A few shorter bristles are scat- 
tered irregularly over the head. Between the antennal groove and the hinder edge 
of the head there is a single bristle, followed by three more close together, and then 
four more arranged in a like manner. A row of short densely set hairs is placed 
along the posterior half of the antennal groove. In one specimen there is a single 
short spine on one side of the head only, at the anterior margin of the antennal 
groove. There are two strongly chitinised genal spines on each side, and also a 
strongly chitinised spine on each side of the anterior portion of the head, just above 
the maxille. The pronotum bears a single row of bristles and a comb of twelve 
teeth. The mesonotum bears one row of long bristles and many small hairs. The 
fused episternum and epimeron of the mesothorax bears seven bristles, two of them 
arelonger than the others and placed just above the stigma, The episternum of the 
metathorax bears three bristles placed in a row, the sternum bears a single bristle 
also. The epimeron is much longer dorso-yentrally than it is broad, it bears two
