INSECTS OF SAMOA. 



Both specimens seem to have suffered through being relaxed for setting, 

 and the citrine colouring gives one the impression that it may have been a rich 

 olive green, as already much of it has faded to a yellowish colour.

There are certain species hitherto placed by Hampson in scattered positions 

 in the genus Endotricha, possessing in the male sex several characters which show 

 them to be closely related. With the exception of the widely distributed 

 Doththa mesenterialis, these species are I believe confined to islands, and it was 

 the discovery of several apparently new species in the islands of the Gulf of 

 Guinea that first drew my attention to this fact. I propose therefore, for the 

 purpose of this paper, to revive Walker's genus Doththa (type : D. mesenterialis 

 Walker) for these species, and I hope later to investigate the other species and 

 their geographical distribution.
