In conclnsion I have to thank Mr. L. B. Front and Mr. J. H. Durrant for 

 working out the Geoinetridae and tlie Mii-role.phloptera, and Sir George Hampson 

 for the great assistance he afforded me witli the Noctuidae and Pyralidae. The 

 new genus CiiUibolu is described by Mr. Durraut. I have described in this 

 article 35 new species, 3 new subspecies, and 5 new aberrations out of Mr. Hartert's 

 Saharan collection, and 1 new si)ecies and 6 new subspecies from elsewhere.

SIPHON APTERA. 



By K. JORDAN, Ph.D., and The Hon. N. CHARLES ROTHSCHILD, M.A. 



The sixteen specimens of fleas collected during Dr. Hartert's expedition to In-Salah 

 belong to four different species of Xcnopsi/lht, one of the species being new to 

 science. The genus Xenopsi/lla is typical of the deserts and steppes of temperate 

 Africa and Asia, although in the tropics the genus is by no means restricted to 

 desert regions. None of the species of Xenopsylla occur in Western and Central 

 Europe, with the exception of A', chcopin, which has liecome cosmopolitan with 

 its hosts, the rats frequenting ships. 



1. Xenopsylla cleopatrae Uoths. (1903). 



4 ? ? , from Flirt Miribel, 13s km. south of El-Golea, o. iv. 1912, off DIpodilbiA 

 Mmpestris rozsikae. 



1 (? 1 ?, from Oued el-Abiod, north of In-Salah, 24. iv. 1912. 



1 ?, from the Southern Oued Mya, 7. v. 1912, on bed in tent. 



The species likewise occurs ou the Central Plateaux of Algeria, and is also 

 recorded from Egypt and the Sudan. 



2. Xenopsylla nubicus Koths. (1903). 



1 c?, 3 ? ?, from S.5 km. south of El-Golea, 10. v. 1912, oiT JkcuIus jacidns. 

 One of the ? ? is possibly X cher sinus Roths. (1906). 

 The species is known from Egypt and Syria. 



3. Xenopsylla regis Roths. (1903). 



1 (?, 1 ?, from Fort Miribel, 13S km. south of El-Golea, S. iv. 1912, off 

 llijiodilluH campcMri.s i-ozsi/tuc. 



The species was originally described from Lahej in South Araliia. 



Ajiart from the bristles and the genital organs. A', regis is characterised by 

 the genal edge being widened downward into a broad ami uliluse lube. This lolie 

 Ik much longer and ninre triangular than in the allied species, but shorter and 

 blunter tJian tiie huuk-lilie genal lobe of I'liriodoidis liycjt'iiOnclii.
