8. Pulex australis si)eo. uov. (PI. IX. fig. 2f> ; X. fig. 34. 3fi). 



Head. — The anterior part of the head, which is more strongly ronnded in the 

 c? tlian iu the ?, is covered with minute hairs, and bears a row of four bristles 

 between the antennal groove and the maxillarj- palpi, and a row of three longer 

 ones before the e)-e. On the posterior part of the head, which is longer in the t? 

 than in the ?, there are three rows of bristles, besides a number of smaller hairs, 

 situated in front on the back, these small ones being especially numerous and 

 prominent in the S. The bristles of the last or snbapical row are nearly ecjui- 

 distant from one another (PL X. fig. 34). Above the antennal groove there is a 

 row of about twentj'-five short spine-like hairs standing close together, the posterior 

 ones being much larger than the anterior ones (PI. X. fig. 34). The maxillary 

 palpns is as long as the rostrum, the first segment being a little longer than the 

 third, the second half as long again as the third and a little shorter than the 

 fonrth. The labial palpus consists of five segments, the second, third, and fourth 

 being nearly equal in length, and tlie fifth. nearly twice as long. 



Thorax. — The pro- and mesonotum bear each two rows of bristles, tlie anterior 

 row of the pronntum not extending halfway down the sides. The epimerum of the 

 mesothorax bears three bristles, two in front and one above the stigma. The meta- 

 notnm bears three rows of bristles, besides some hairs near the base on the back, 

 and is armed at the edge with ten to fifteen very short teeth. The epimerum of the 

 metathorax bears two rows of bristles — namely, a row of five at the hinder edge 

 from the stigma downwards and a row of six halfway towards the base, the 

 uppermost bristle being on a level with the stigma or a little more dorsal. 



Abdomen. — The first abdominal tergite bears two rows of bristles, the anterior 

 liristies being short. On the other tergites there is one row of bristles, besides a 

 few hairs on the back, representing the second series. The first tergite has a comb 

 similar to that of the metanotum, while tergite 2 bears only two teeth on each side 

 on the back, the following four tergites one or no tooth. The seventh tergite bears 

 a stout apical bristle on each side, whicli is less than twice the length of the most 

 ventral bristle of the same tergite, and which is acct)mpanied dorsally by a very 

 short hair. The stigma stands in between the first and second bristle, or on a level 

 with the second. Its diameter is less than three times the length of the diameter 

 of the groove of the ventral bristle of the tergite. The abdominal sternites have a 

 regular row of bristles. On the first sternite the row is lateral, the bristles being 

 short, and there is another row of three or four in front of it. 



Legs. — The hiudcoxa is as broad as it is long at the meral suture, which 

 separates the coxa into a posterior and an anterior portion. There are three bristles 

 ]iosteriorly at the apex, the ventral one being the shortest, and a regular row 

 anteriorly at the edge. There is no comb on the coxa. Besides the hairs near 

 the anterior edge of the hindcoxa, there is on the outer surface before the middle 

 a downward row of four or five bristles. The anterior femur bears on the onterside 

 numerons short hairs. The mid- and hindfemora bear on the onterside two rows 

 of hairs, one subventral and the other lateral, this being irregular and more or 

 less incomplete. On the innerside there is a regular series of from si.x to eight 

 bristles. The tibiae have a number of hairs along the ventral edge. On the mid- 

 and hindtibiae there are on the onterside, besides those ventral hairs, a row of 

 ten from the base to the apex, and two more hairs which are situated between 

 the fourth and seventh pair of dorsal bristles, being more dorsal in position than
