KB.—It is worthy of note that, of the 180 moths listed above
and representing 25 species, no fewer than 16 species, comprising
164 moths, cannot for the moment be referred to any known species.
Further study may reduce the suspected number of new species
but it is evident that the Rub' al Khali has developed a strikingly
peculiar lepidopterous fauna.
