C. 0. Waterhouse, Tr. E. Soc. 1875, pp. 331-337, describes apterous 
species mostly found by Charles Darwin at Tierra del Fuego, under 
stones covered to some depth at high water. These species were many 
years ago described by G. R. Waterhouse, but were never published, as 
the MS. was lost. 
Rygmodus pedinoides, Blanchard {nec White, which belongs to the 
SydrophilidcB), apparently belongs to this group ; TanycTiilus metallicus, 
White, according to Blanchard, is an Amarasoma, but the latter author’s 
insect is probably quite different from White’s : C. O. Waterhouse, Cist.
