On some Pseudoscorpions in the Brilish Museum. 451 



EuTOLMuSj Loew. 

 Linn. £nt. iii. p. 459 (1848). 



A species described by Macqnart as Asilus armatus (see 

 Dipt. Exot. Suppl. 1, p. 219, pi. viii. fig. 17, 1846) has been 

 placed, evidently in error, under Eutolmus in Kertesz^s Cat. 

 Tiic reference given to Loew, Bcsclir. Europ. Dipt. ii. p. 164, 

 note 2 (1871), refers to Machimus armatus, Jaenn., a Euro- 

 pean species now stated to be a synonym of Machimus pilipcs, 

 Meig. From the figure of Asilus ai-maius it is evidently not 

 a species of Eutolmus or Machimus, if the figure is at all 

 correct. 



The genus has thus not yet been recorded from the 

 Australasian Region nor from the Oriental Region. 



L. — Xote on some Pseudoscorpions in the British Museum. 

 By Edv. Ellingsen. 



One of the most interesting facts to record concerning the 

 collection in question is a biological one — that of the capture of 

 Chelifer hayoni, Ellingsen, on a bird, Anas undulata. In my 

 paper " Die Pseudoskorpione des Berliner Museums " *, p. 402, 

 I made a remark regarding the capture of Chthonius tetra- 

 chelaiics, Preyssler, a Palsearetic species, in the Seychelles 

 Islands, in the Indian Sea, I wrote : — " Wie diese zerbrech- 

 lichen, kleinen Tierchen, die palaavktisch sind, in die weit 

 entfernt liegende Inselgruppe Seychellen gekommen sind, ist 

 nicht leicht zu fassen ; vielleicht mochten sie mitVogeln ver- 

 schleppt worden sein." Till that time (1910), or, rather, till 

 now, no record of the capture of a pseudoscorpion on a bird 

 has, as far as my knowledge goes, been given in the literature. 

 The notice mentioned above is thus the first record of such 

 a thing, and this fact is of great value in the explanation 

 of the occurrence of pseudoscorpions in jdaces where they 

 beforehand could not be expected to be found, such as the 

 capture of Chthonius tetrachelatus in the Seychelles. Thus 

 this biological fact is available for the solution of a zoo- 

 geographical question. 



Another fact of some interest is the occurrence of Chelifer 

 nodosus, Schrank, in Africa. This is a European species, often 

 found clinging to tiie feet of flies in houses ; the same is the 



* Mitt. aus. d. zoolog. Museum in Berlin, iv. Bd. iii. Heft. (1910).
