4. Xenopsylla taractes spec. nov. (te.\t-fi{,'.). 



2 c?c?, from hull-wiiy butwoeii Onargla and El-Golea, lU. iii. IDTJ, off Mcriones 

 schousboei. 



A close all}' of X. mijccrini Mothti. (l'.JU4) M\i X. ramesis Roths. (1904). It 

 is nearer to the former, the S Ijcaring two ventral bristles on each side of the 

 eighth abdominal sternite as in mt/ceriiti, whereas this segment of ramcsis has 

 a row of bristles instead. The genital armatnre of the ninth tergite consists of 

 three processes. Tiie npper (and onter) ))rocess, F in text-fig., is the largest. 



Modifietl abdominal segments of ^ of -V. iaractes. 



It is less liroad at the apex than in A', ramcsig, and also less markedly trnncate 

 than in that species, while it is rather broader apically than in X mijcerini. The 

 number of bristles on tliis process and their size are slightly variable. The 

 processes P' and P- (cf. text-fig.) are much less chitiuised than i)rocess F. In 

 X. mijcerini process P' almost reaches to the apex of process F, but in the present 

 species it is much shorter than F, being also broader than the corresponding 

 process of X. mycerini. Process P- is different in shape from that process of 

 X. mijcerini and ramcsis, and bears two minute hairs. The ninth sternite (ix. st.) 

 is rather broad throughout, with the apex obli((uely rounded, as shown in the 

 figure.
