Hypsophthalmus yfii. nov. 



c? ? . Allied to Chimaeropsi/lla, Duiopsi/lltis, Palaenpsj/lla and Lfipfopxi/lla. 

 Genal comb vertical. Eye near base of antenna. Laliial palpus consisting of four 

 segments. Frons withont short stout spiuiform bristles near anterior margin. 

 Mandibles slender. One long antepygidial bristle accompanied by two very small 

 ones. Vertical lines of metepimerum ventrally not more numerous than dorsally 

 Hindcoxa on inner snrface with a comb or patch of small spiuiform bristles. Fifth 

 segment in all tarsi with fonr pairs of plantar bristles, all lateral. 



Genotype : H. campestria spec. nov. 



We also place here the species described as Ctpnopsi/Uus agaiiippes Roths. 

 (1902) and Ctenopsyllus granti Roths. (1904), both from the Cape Colony. The 

 three species agree in the characters mentioned above, but differ inter se so widely 

 in other structures that they may ultimately be classified under different genera. 



41. Hypsophthalmus campestris spec. nov. (text-figs. 42, 43 and 44). 



(J?. The irons is almost evenly curved, being minntely angnlate just below 

 the centre. The structure of the skeleton is different above and below the angle,

as is also the case in Le.ptopsujlla (and some other genera). An internal incrassation 

 situated below the angle extends from the anterior edge of the frons inwards, 

 terminating and being most strongly chitinised near the base of the last but one 

 genal spine (counted from below). There is a row of six bristles along the frontal 

 edge, one bristle behind the eye, a second in front of tiie penultimate genal spine, 

 and a third nearly on a level with the most ventral bristle of the anterior row. On 

 the ]iorti(in of the frons below the angle there are three pale dots, two being placed 

 close to the comb and the tiiird towards the anterior margin. The genal comb 

 contains five spines as in IHnop.^i/llKfi, the second from below being the longest.
