in transferring them to other animals, and even to human 

 beings. When the tube is first placed upon the animal the fleas 

 are quite excited, but they gradually settle down, and if not 

 disturbed, will take a full meal at one feeding. Adults have 

 been kept alive for fifty days, but this is quite unusual and un- 

 doubtedly they live longer under natural conditions.

On the Species of the Genus Basileus Sauss. 

 and Pict. (Orth., Copiphorinae). 



By B. P. UVAROV. 



( With one figure in Text. ) 



The genus Basileus (Orthoptera, Copiphorinae) was estab- 

 lished in 1899 by Saussure and Pictet, with one species only 

 B. diadcmatus Sauss. & Pict. W. Kirby, in the course of com- 

 piling his catalogue, rightly included in the same genus Locitsta 

 repanda Walker, but he was quite wrong in regarding re panda 

 as identical specifically with diadematus, since Walker's species 

 differs very much even from the description of diadcmatus. 

 He, nevertheless, synonymized diadcmatus with repanda, the 

 latter name being adopted by him according to its priority. This 

 synonymy has been accepted also by H. Karny in his latest 

 revision of Copiphorinae. 



As I had tlie opportunity of studying Walker's actual type 

 of repanda, as well as another female specimen of the same 

 species, and compared them with one female undoubtedly be- 

 longing to diadematus, I feel myself justified in giving the fol- 

 lowing key for separating these two, and the only known, 

 species of Basileus.
