ON SOME EUROPEAN SIPHONAPTERA. 

 BY HON. N. CHAKLES ROTHSCHILD, M.A., F.L.S. 



Through the Iciudness of Dr. Geza Horvath we have lately been 

 able to examine specimens of Isclinoysylhis wagneri, Kohaut (1903). 

 The insect is unclonbtedly identical with I. intermedius, Rothschild 

 (1898). 



In Tijdschr. v. Ent., 1909, pp. 96—108, Dr. A. C. Oudemans 

 described a female and a male of Ischnopsylhis under the new name of 

 I. fichinifzi. In a subsequent paper (Zool. Anzeig., 1909, p. 736) the 

 author stated that the female belonged to I. inter medms, Rothsch. 

 The descrijDtion of the specimen, however, does not agree with any of 

 our females from England and the Continent in several of the details 

 on which Oudemans lays stress, for instance, in the bristles of the 

 abdomen and legs. As the author states his description and figures 

 to be " peinlichst genau," it is perhaps venturesome on our part to 

 assume that some of his statements are nevertheless incorrect, and 

 that the female of schmitzi is after all the same as I. intermedius. 



The male of schmitzi, of which the author very kindly gave us a 

 specimen m exchange, proves to belong to I. simplex, Rothsch. (1906). 



The synonymy of these bat-fleas therefore reads : — 



1. ISCHNOPSYLLUS INTERMEDIUS, RotllSch. (1898). 



Ceraptopsylla intermedius, Rothsch., Nov. Zool., p. 543, t. 17, fig. 15 



(1898). 

 Ceratnpsylla vrngneri, Kohaiit, Allat. Kozlem. ii, p. 62, t. 7, fig. 3, 



8.9.10 (1903). 

 IsclinopsyUus schmitzi, Oudemans, Tijdschr. v. Ent., p. 97 (1909) 



( ? only ; ^J alia species) . 



2. — IscHNOPSYLLus SIMPLEX, Rothsch. (1906). 

 Ischnnpsyllus simplex, Rothsch., Nov. Zool., p. 186 (1906). 

 Ischnopsyllus schmitzi, Oudemans, I.e. {(^ only ; ^ alia species). 



Besides these two species five more eight- combed bat-fleas are 

 known from Europe, namely, I. elongatus. Curt. (1832), /. ohscura, 

 Wagn. (1898), I. octactenus, Kolen. (1856), I. variabilis, Wagn. (1898), 

 and I. decimpilata, Wagn. (1898) ; to which I can add another 

 species, which, however, may possibly be the true female of ohscura. 

 The specimens described as females of obsciira by Wagner probably 

 he himself states, did not belong to that insect.
