dorsal incrassation before the centre. Bristles ou second segment of antenna short. 

 Bristles of body and legs numerous. Two antepygidial bristles in both sexes on each 

 side. Fifth tarsal segment with four pairs of lateral bristles, and in the fore- and 

 midtarsi with an additional ventral pair proximally. One receptacnhim seminis.

This is the nearest approach to the Stepkanocircus group of genera which has 

 as yet been discovered. The homology of the combs is at once apparent if we com- 

 pare fig. 9 with fig. 13. The two long genal bristles present in Craneopsijlla (the 

 South American genus representing in that continent the Australian genus Stepkano- 

 circus) are also found in Clcopsijlla. The chaetosity of the body is similar in the 

 two genera, but Craneopsylla has lost the long bristles placed in front of the frontal 

 comb in Cleops>jUa, with the sole exception of the most ventral bristle, which is

present in Craneopsijlla. The frontal portion of the head of Cleopsylki is less 

 modified than in Craneopsylla, whereas that new genus is more specialised than 

 Craneopsylla in possessing only four segments to the labial palpus and in haying 

 lost the proximal pair of 2)]antar bristles on the fifth hindtarsal segment.

Head. — cJ ? . The frons (text-fig. 9) has a comb of seven spines, of which the 

 ventral one is long and pointed, and a row of five bristles, there being numerous 

 small hairs in front of and behind the comb. The gena bears a comb of four spines 

 and a small spine on the genal process. The occiput has four rows of bristles. The 

 rostrum reaches to four-fifths the length of the forecoxa. 



Thorax. — The prothorax has two rows of bristles, and a comb of twenty-two to 

 twenty-four pointed spines. The meso- and metanota have also two rows of bristles,
