that I could 11 ot observe any difference betweeu tliem. Indeed I 

 have exaniined the insects carefully ; they are of the same species, 

 viz. Laelaps celeripediformis Ouduis., described by me in the Tijd- 

 schrift voor Entomologie. (This description may not appear be- 

 fore the year 1902). So the geographical distribution of this 

 species is wide. The beetle was caught during the Sumatra-Expe- 

 dition of 1877. 



On p. 193 of the same volume of the above-mentioned Tijdschrift I 

 noted the receipt of a species of Rhipistoma from Mr. Snelleman 

 (Sumatra-Expedition of 1877). Prof. G. Neumann, of Toulouse, 

 recognized them to be Haemaphysalis leachi (Andouin), 2 cf. They 

 were found on Felis tigris L. 



On the same page I mentioned two kinds of Rhipicephalus, 

 found on Bos bubalus in Sumatra (Expedition of 1877). Prof. G. 

 Neumann determined them as Rhipicephalus annulatus caudatus 

 Nu. (ƒ and Haemaphysalis cornigera Nn. cT. 



3. Acari of Italy. 



In the Tijdschrift voor Entomologie, vol. 39, p. 137, I noted 

 that Dr. Everts presented me with a Laelaps sp. of Naples. These 

 insects are Macrocheles marginatus (Herm.), viz. a tritonympha ho- 

 moiomorpha feminina and an adult female. They are of 1879. 



Mr. S. A. Poppe, of Vegesack, sent me a tube with Acari found 

 on a Rhinolophus ferrum equinum, at Triest, 27, I, 1898. They 

 all belonged to one species, which is new to science, and which 

 I will call Liponyssus rhinolophi Oudms., llOV. sp. (see below). 



4. Acari of Cockin China, 



In 1879 Dr. Henri W. de Graaf presented me with two Ambly- 

 omma found on a kind of Testudo in Cochin China. See the Tijd- 

 schrift voor Entomologie, vol. 39, p. 192. Prof. G. Neumann, 

 of Toulouse, kindly determined them as Hyalomma affine Nn. cf.
