As the genus Oenistis Hiibner, 1822, appears to be available and to have been 

 adopted for 0. quadra Linnaeus, I do not think Hampson was in order in using it 

 for Phalaena (Tinea) entella Cramer, Uitl. Kapellen, iii (18), p. 27 and index, 

 pi. 208, Fig. D, 1779, and in consequence I have adopted the generic name 

 Philagria Kirby, 1892. 



Cramer gives as the habitat for P. entella the Coromandel Coast, and 

 Fabricius gives as the habitat for his Noctua delia, " Insula Amsterdam." I am 

 not quite sure of the geographical application of this name,* but the type, which 

 is in the Banks Collection in the British Museum, agrees with the Samoan 

 subspecies. From investigations I have made with regard to the genitalia, 

 <$ and I have come to the conclusion that we have here a widely distributed 

 species, represented in various localities by structurally well-differentiated 

 subspecies. The typical subspecies is Philagria entella entella Cramer, occurring 

 in India and Ceylon, and the subspecies with which we are here concerned is 

 P. entella delia Fabricius. 



5. Macaduma samoensis, sp. n. (Plate VI, fig. 10). 



Palpus and antenna ochraceous buff. Head with frons pale bufi deepen- 

 ing to warm buff at vertex. Thorax avellaneous, the various parts (patagium, 

 tegula, etc.) edged with pale buff. Abdomen warm buff, laterally ochraceous

 costa, forming a heavy blotch in the middle of the cell, crenate (concavities 

 basad) to inner margin. A fine irregularly and indistinctly crenulate deeply

* Brigham's Index to the Islands of the Pacific gives Amsterdam islet on the coast of New 

 Guinea, 0°,20'S, 132°.08'E. ; Amsterdam (New), a name given by Tasman, in 1642, to Tongatabu.
