ones on the outer side, exclusive of the apical ones, and eight or nine dorsal pairs of 

 bristles, besides one or two single dorsal bristles. 



Modified Segments. — S- The eighth tergite has four or five bristles above the 

 stigma. The process P (text-fig. 7) of the clasper is longer than in rosenbergi and 

 bears ten to twelve bristles. The small manubrium M' has proximally a projection 

 which is triangular in a lateral view. The movable process F is similar to that of 

 rosenbergi, but shorter. It bears a ver}' strong, black, curved, subapical spine, above 

 which there is a smaller bristle and a thin hair, and at the ventral margin a regular 

 row of twelve to fourteen bristles. These latter bristles are pale as in rosenbergi, 

 proximally rather stout and distally thin. The ninth sternite (text-fig. 7, IX. st.) 

 has at the apex of the distal arm a large, short, obtuse spine, as shown iu the figure. 

 This distal arm of the ninth sternite is much more curved than in rosenbergi. 

 Proximally to the "finger" the clasper bears at the ventral margin a number of 



broad, long membraneous flaps, which are presumably modified bristles. ? . The 



seventh abdominal sternite (text-fig. 8, VII. st.) is less rounded than in rosenbergi. 



A small series from Pachacayo, 12,000 ft., March 27, 1913, off a rat. 



Also from Bolivia and Chile. 



Cleopsylla gen. nov. 



We base this genus on a most interesting species, which connects heptopsylla 

 and allied genera with Craneopsi/lla and Stepkanocircus. 



Head (text-fig. 9) divided by the antennal groove as in the genera mentioned. 



Fig. 9, — CUoj>syllti toumseudi ^. 



Frons strongly reclining backwards ; a comb at the posterior edge of the gena, 

 and, separated from this comb, another comb of large spines parallel with the frontal 

 margin, these spines inserted at about one-third the way from that margin to the 

 antennal groove. In front of the frontal comb a row of long bristles. The portion 

 of the frons which bears this comb not divided off by a suture from the genal portion 

 as in Craneopsylla and Stepkanocircus. Mouth-parts short ; ape.x of maxilla not 

 sharply pointed ; labial palpus consisting of four segments. Occiput with internal
