arcania having a second large piipilled eye below apical eye (one 

 specimen with tiny third eye-spot above normal spot), and this 

 appears to be Mr. Tutt's ab. hipiipillata {Knt. Hec, x., p. 66). A most 

 unexpected find in this family is a large but ragged specimen of 

 var. {et ab.) balearica, described by myself in the Knt. Ecc, vol. xvi., 

 p. 222. '
