LIST OF SIPHONAFTERA COLLECTED IN ALGERIA IX 

 THE SPRING OF 1911. 



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



(With 2 test-figures.) 



DURING April and May of last year the present Lord Rothschild and the 

 senior author visited several places in Eastern Algeria for the purpose of 

 collecting Lepidoptera and incidentally other insects. Their stay at Souk-Ahras 

 and Hammam-Meskoutine was long enough to allow them also to devote some 

 time to the trapping of small mammals. The fauna of these places is that of 

 the northern Atlas district, the mammals obtained being the same species as 

 those which were collected on a former occasion at Alger and Hammam-Rirba. 

 Although individuals were ftiirly numerous, little variety as to species was obtained 

 as regards hosts as well as parasites. 



By far the commonest flea was Ceratophyllus barbarus, which occurred on 

 nearly every sort of host found. 



The most interesting species in the collection is Leptopsylla amitina, which 

 was described by us in 1914 from a single S, but of which a small series of 

 both sexes has been procured at Hammam-Meskoutine. 



Hen-houses, and a large number of nests of Martins and Sparrows, as well as 

 some other bird-nests, were examined, but only one flea found. The very numerous 

 bats taken at Hammam-Meskoutine yielded no fleas.

3. Ceratophyllus barbarus Jord. & Roths. (1912)
