33. Dinopsyllus apistus spec. nov. (text-fig. 35). 



This species and the ne.\t are easily distinguished in the iS, but the ? ? do 

 not seem to present any reliable differences, provided that the specimens which we 

 presume to be the females of apistus belong to this species and not to the next. 



Fici. S.'j. — DinopsijllKs apistua. 



D. apistus and all the following species are so closely allied to I>. lonyifrons 

 that most of the characters meutioned in the above description of that species apply 

 equally well to these other species. For the sake of brevity we shall therefore 

 I'liik-avour to avoid repetition, and confine the descriptions of the following species 

 as much as possible to the main di^ftinguisiung ciiaracters. With the exception 

 of the last species (from Angola) the thorax and abdomen bear less bristles than 

 in D. longi/rons, the spines in the abdominal combs are less numerous, the cf i 

 have no comb on the first abdominal tergite the eighth abdominal tergite of 

 the ? ? has less than forty bristles below the stigma, the irons of the <i S is 

 shorter, and their clasping organs exhibit some distinctions in sinipe and in tiie 

 number and position of the bristles. 



i. D. apistus J is recognised by the apical ventral angle of the eighth
