2. Acari of Congo. 



Mr. S. A. Poppe , of Vegesack , asked me to determine some 

 Acari, found by Mr. Paul Hesse, on a Vespenigo paf/emfecheri 

 Nck., 18, IX, 1886, in Banana. I found in the little tube: 



Eremaeus hessel Oudms. , nov. sp. , 



lAponyssus musculi (C. L. Koch). 



Mr. Anton Greshoff, of Brazzaville, Congo, handed me four 

 specimens of that locahly, aUied to Amhii/omma venustum C. L. 

 Koch and A. aunulipes C L Koch (See Tijdschrift voor Entomo- 

 logie, V. 39, p. 192). The animals were caught in 1893. Prof. 

 G. Neumann, of Toulouse, determined them as Amhlyovima splen- 

 didimi Gieb. 



In 1896 I received from Mr. Anton Greshoff a few Thromhidium, 

 which prove to be Tromhidium tinctoiium (L.), and a lot of Ixo- 

 didae , whicli Prof. Neumann determined as : 



Ainblyomma splendidum Gieb. <? , Î ,

 an Acanis , found parasitic on Discocyrius fune, tus Butler, an 

 Opilionid of Chili They are larvae, but characteristic enough to
