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 tibiae 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 tibiae. The femora 

 bear ventrally one thin bristle near the joint with the tibice. Length 2-6mm. 



I have examined four specimens of this species from Petaurus 

 australis, from Victoria. The type is in the British Museum. 



Typhlopsylla in gens, sp. nov. (fig. 4). — The rostrum of the head is very long, 

 reaching to the end of the coxas ; 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 is a 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 tibice are 

 covered with hairs, the bristles at the hinder edge of the tibiae being strongly 

 chitinised. The bristles at the apex of the anterior tibi^ are as long as the first 

 and second tarsal joints ; those of the middle tibite are shorter, being about the 

 length of the first and half the second tarsal joints, while those of the posterior 

 tibias are only as long as the first tarsal joint. Length 4-2mm. 



This species was found on Bathyergns maritimus in Cape Colony, 

 by H. A. Spencer. The type is in the British Museum. 



PuLEX MADAGASCAEiENSis, sp. nov. (fig. 3). — The sccond 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 maxillae. 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 

 are longer 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-ventrally than it is broad, it bea,rs two
