LIST OF SIPHONAPTERA COLLECTED IN PORTUGAL. 



By dr. K. JORDAN and THE HON. N. CHARLES ROTHSCHILD, M.A. 



'T^HE knowledge of the distribntion of the Sii>honaptera being very limited, 

 -*- we deem it advisable to publish the list of the fleas we canght in Portugal, 

 althongh the number of species obtained is very small. The junior author visited 

 Lisbon and Cintra early in 1909, and the senior author spent some time at the 

 same places in the spring of 1910, and also collected in Algarve, the most southern 

 province of Portugal. Four of the eight species collected were new at the time 

 of capture. 



1. Pulex irritans L. (17.o8). 



We obtained a number of specimens at Cintra, but were agreeably surprised 

 at finding this pest a rarity in the honses at which we stayed in Algarve. 



2. Archaeopsylla erinacei maura subsp. no v. (Text-fig. 1.) 



One <S and four ? ? from Monchique, Algarve, an Erinaceus europaeus. 



The specimens of A. erinacei collected in the Western Mediterranean countries 

 are different from the more northern examj)les, more especially in the Si- We 

 have compared, besides the S from Monchique (the type of maura), two SS from 

 Mazagau, Morocco, another from Majorca, Balearic Islands, and three S S from 

 Biskra, Algeria. All present the following differences : 



The short manubrium of the eighth tergite is, in a lateral aspect, flat and 



Fm. 1. 



obtuse. The manubrium of the ninth tergite is slightly longer than in trne 

 erinacei. The large flap of the clasper is more than one-third longer than in 

 erinacei from more northern or eastern localities, the apex being much more 

 produced (text-fig. 1). The distance from the apex of this flap to the proximal, 

 slanting portion of the dorsal margin is the same as the distance from the base 

 of the spine situated at the tip of the genal process to the frontal margin of 

 the head measured in a straight line running below the eye, whereas in true 

 erinacei the length of the flap only equals the distance from that spine to the 

 anterior edge of the eye. Moreover, the eighth abdominal tergite bears on each 

 side a row of three bristles in all the JcJ.
