St. I. 16. xi. 25. Clarence Bay, Ascension, 16-2701. Several specimens. 

 St. 2. 17. xi. 25. Ascension. Littoral. 8 specimens. 



The species was hitherto known only from St Helena, but its occurrence at Ascension 

 was to be expected, so it is very satisfactory that it has now actually been found there.
