100 Tianaact tons.— Zoology. 



Defined oiigiually to include a species from the South 

 Pacific islands, with which the following agrees entirely in 

 essential structure, although differing much in supei-ficial ap- 

 pearance. The genus belongs to the group of Erechthias, 

 which I formerly separated as a distinct family {ErechihiadcB) , 

 but I am now of opinion that, although a very natural group, 

 it cannot be kept separate from the Tineidce. 



Decadarchis monastia, u. sp. 



2 . 10mm. Head fuscous, face wliitish-fuscous. Palpi,

 tips ; a moderate rather irregular whitish-ochreous spot on 

 costa beyond middle : cilia rather dark fuscous, mixed with 

 blackish round apex. Hindwings rather dark bronzy-fuscous ;
