is three and a half times as ]oDg as the largest transverse diameter of this process. 

 The ninth sternite bears three sets of bristles on the ventral side, an apical row of 

 nine or ten, of which the last two are long, a median row of seven or eight, and 

 a nnmber of thin bristles situated along the proximal half of the segment. The 



dilated apex of the ninth sternite is dorsally flattened. ¥. The seventh sternite 



(text-fig. 32) is rather deeply sinuate. The distance of the long subapical bristles 

 of this sternite from the bottom of the sinus equals at the most the distance between 

 four bristles of the last row of the seventh tergite. The eighth tergite nearly 

 always bears four bristles above the apical sinus and, as in the other species, a thin 

 one in the sinus, one example having three instead of four bristles.

31. Dinopsyllus hirsutus Roths. (1908). 



C'leiiojjfyUus Jiirsulus Rothschild, Eiit. Mo. Mai/. (2) xix. p. 78. no. 4. tab. 1. fig. 4 (1908) (Ruwenzori). 



Described from a single ? obtained on Mi/s niiicittatus Imiaris. This specimen 

 agrees closely with the females of the ])receding species, but the differences are 

 such that they would not justify us in treating hirsutus and echinus as being the 

 same insect. 



?. D. hirsutus shares with D. echinus the dense reticulation of the body, the 

 long second segment of the maxillary palpus, the shape of the outline of the head, 

 and the size, but is distinguished by the following characters. The denticulate 

 appearance of the sides of the abdomen is absent from D. hirsutus, the metepi- 

 merum bears only 27 (24)* bristles, and the combs of the abdomen contain very 

 few spines, the numbers lieing 5, 3, 2, (4, 3, 2, 0). Moreover, the seventh 

 tergite is abruptly dilated below the antepygidial bristles into an almost rectangular 

 lobe, the corres])ouding lobe of D. echinus being much more rounded and projecting 

 much less. The distance of the long bristle nearest to the base of the sinus of the 

 seventh sternite is much larger than in ]). echinus, equalling the distance between 

 six bristles of the subapical row of the seventh tergite. The eighth tergite bears 

 three bristles at the apical margin above the sinus, the upper bristle being much 

 stouter and shorter than the second. The basal abdominal sternite bears 10 (17) 

 bristles on the side in I), hirsutus, and 22 to 35 in the ? of T). echinus. 



Mr. Kemp did not nn'ct, with this species. 



In the species now following tlie surface of the body does not bear a distiiict 



reticulation excej)t in a few restricted places — e.g. on the abdominal sternites in 



between the bristles — whereas the vertical lines are very obvious. There are few 



transverse connections between these lines. The dill'ereiice between the preceding
