SIPHONAPTEEA COLLECTED BY MR. ROBIN KEMP IN 



TROPICAL AFRICA. 



By Dr. K. JORDAN and the Hon. N. CHARLES ROTHSCHILD, M.A. 



MR. ROBIN KEMP (-011601601 miimmals dnrino; the years 1910-11 in British 

 East Afriia, Uganda, and the adjoining district of the Belgian Congo, and 

 sent ns a large collection of parasites which he had secured from some of his 

 mammal captnres. No real collection of the Ectoparasites of this district had 

 previously been made, so it is not surprising that the present collection contains 

 many interesting forms and new species. 



Mr. Kemp secured thirty-nine si)ecies of Sip/ionaptera in all, of which twenty- 

 one are new. Several of these new species have lieen found on mammals with 

 fossorial habits, and their study has greatly assisted to correct the classification of 

 certain groups of iieas. 



In the present paper we have separated some genera from Ctenophthalmus and 

 Li'i>topsylla, as a result of the investigation of certain of the species received from 

 Mr. Kemp. 



Mr. Kemp's collection comprises two new species of the genus CtenocephaUis 

 allied to the common dog-flea. These two — together with woLlastoni and rosmarus, 

 also species from the Ethiopian region — are all the known members of the genus 

 Ctenoceplialus (ajjart from canis and Jelis), and indicate that Africa is the real 

 home of this genus of fleas. Apart from the common Ct. canis AiiA felis, no 

 member of this genus is known from any country other than Africa. 



In the case of two of the genera we have enumerated all the species known 

 from the Ethiopian region. 



1. Echidnophaga larina Jord. & Roths. (1906). 



Echidnophaga larhia Jordan and Rothschild, in Thomps. Yates and Johnst. Lahur. Rept. vii. 1. 

 p. 49. no. .S. t. 1. fig. 1-2, t. 2. fig. 18, t. .S. fig. 25 (Iflilfi) (Cape Colony, Somaliland, Abjssinia). 



1 ? from Eusso Nyiro, British East Africa, January 31, 1911. 

 4 ? ? from Masaka, Uganda, April 2, 1911, off a domestic dog. 



2. Echidnophag'a gallinaceus Westw. (1875). 



Siiicopmjlluii gaUiiiacrus, Westwood, E)it. .l/ii. Matj. .xi. p. 2-lG (IST.T) (Ceylon). 



Echidnophiga (jutliiiaeeus, Jord. & Roths., /.c, p. 52, no. 5. t. 1 . fig. 1, t. 2. fig. 14. t. 8. fig. 21, t. 4. 

 fig. 27 (11)06) (tropical and subtropical districts o£ Asia and Africa, and Southern U.S.A.). 



3 ? ? from Taveta, Kilimanjaro, May 12, 1910, off i/«s rattus. 



1 c? from Nakurn, British East Africa, September 23, 1910, oW Herpestes spec. 



3. Echidnophaga aethiops Jord. & Roths. (1906). 



Echidnophaga aelhioji.i Jordan and Roth-schild, Ix. p. 51. no. 4 (19015) (Namaqualand). 



1 ? from Voi, Britisli East Africa, April 13, 1910, off a bat. 



The second segment of the maxillary pulpus is not quite so short in this 

 specimen as in the type, but is nevertheless shorter than in K gallinaceus. The 

 hindcoxa, moreover, bears a larger number of spinifonn bristles than the type- 

 specimen. E. (lethiops appears to be close to K. 9niir/)ia Tirab. (1903), whicli occurs 

 on rats in Italy.
