422 Mr. Butler's descriptions of Lepidoptera- 



of the discoidal areas ; interno-basal area of primaries greenish 

 opaline in certain lights ; body below and legs sordid whitish or 

 pale whity brown. Expanse of wings, 21 mm. 



Tonga Island (Friendly Islands). 



HYDEOCAMPID^. 

 PSEUDEPHYRA, n. g. 



Apparently nearest to Homojiliysa, though the palpi differ 

 considerably ; wings broad, having the general aspect of the 

 Geometrid genus Ephyra, especially of E. splendens : very like 

 HoTnophysa in neuration ; body very robust, not extending beyond 

 the secondaries ; palpi porrected, large, compressed, expanded in 

 front by a long fringe along the anterior surface, the terminal joint 

 small and directed slightly downwards so that the anterior, or 

 more strictly speaking, inferior, margin of the palpus is elongate 

 sigmoidal ; antennae filiform, extending to beyond the middle of 

 the wing ; legs moderately long, stout, and somewhat compressed. 



66. Pseudephyra straminea, n. s. 



Bright straw-yellow ; primaries with a subbasal reddish ochreous 

 baftd, bounded by a metallic leaden line and sprinkled with metallic 

 scales ; reniform spot indicated by two plumbageous dots connected 

 by short ochreous lines; an angulated black-bordered reddish 

 ochreous discal band, bounded internally by a plumbageous line of 

 scales ; external margin irregularly bordered with reddish ochreous ; 

 secondaries with a dot at the end of the cell, and the external 

 two-fifths reddish ochreous, the latter crossed by a discal band 

 similar to that on the primaries ; a line of jjlumbageous scales close 

 to outer margin ; abdomen reddish ochreous crossed by slender 

 black lines ; under surface pale stramineous ; the wings crossed by 

 arched discal blackish bands, which do not reach the margins. 

 Expanse of wings, 19 mm. 



Var. The reddish ochreous spots and bands replaced by black 

 spots and broader greyish brown bands mottled with black ; the 

 plumbageovis scales remaining. Expanse of wings, 18 mm. 



Peak Downs. 



NiPHADAZA, n. g. 



Apparently nearest to Oligostiyma ; wings narrow, elongated, 

 acute at apex ; primaries with the outer margin very oblique ; 

 costal margin nearly straight, costal vein extending to about the 

 apical third of costa ; subcostal five-branched, emitting its first 

 two branches before the end of the cell, its third just before the
