on each side towards apex. Middle tibiae in $ with dense expansible hairs beneath ; 

 posterior tibiae in $ beneath fringed with very long projecting whitish hairs. Forewings 

 elongate, posteriorly dilated, costa hardly arched, slightly prominent beyond middle, apex 

 obtuse, more prominent in g, termen faintly sinuate, little oblique ; 7 and 8 short-stalked, 

 8 to termen ; pale brownish-ochreous ; suffused dark fuscous dots on costa at f-, at 

 end of cell, and on dorsum at f , in $ connected by a fine suffused sinuate fuscous line; 

 a terminal series of minute triangular dark fuscous dots connected by a fine line, less 

 marked in ? : cilia pale oclrreous tinged with grey. Hindwings fuscous, suffused with 

 pale ochreous towards costa anteriorly ; cilia ochreous- whitish, with light fuscous sub- 

 basal shade. 



Aldabra ; two specimens. Allied to transversetta Snell. rather nearly, with similar 

 structure of legs in $, but distinct by different form of wing (prominence of costa and 

 sinuation of termen), paler colouring, and less developed transverse line. 



Simaethis Leach. 



67. Simaethis gratiosa, n. sp. 



$. 13 mm. Head dark fuscous partially sprinkled with white. Palpi with five 

 whorls of dark fuscous white-tipped scales. Thorax ferruginous-brown sprinkled with 

 whitish. Abdomen dark fuscous, segmental margins sprinkled with whitish. Forewings 

 elongate-triangular, costa gently arched, apex obtuse, termen rounded, somewhat oblique ; 

 dark fuscous ; an orange-fulvous elongate patch extending beneath costa from base to 

 about middle, and another occupying dorsal area beneath fold from base to middle ; 

 some scattered whitish scales on basal area ; two fine transverse lines of white irroration, 

 first before middle, sinuate inwards below middle, second about f, rather irregular, 

 from ^ to below middle forming a quadrangular loop outwards ; a white dot in disc 

 beyond first line, and a short fine white transverse mark in disc at §, beneath costal 

 section of second line ; some slight orange-fulvous suffusion in disc between these ; 

 a patch of orange-fulvous suffusion along termen, preceded by some whitish irroration : 

 cilia white, with basal third dark fuscous, and dark grey patches at apex, middle of

 somewhat curved parallel white striae from costa beyond middle to just before tornus ; 

 three short white wedge-shaped marks on costa posteriorly, extending into cilia ; apex 

 suffused with blackish ; a minute white dot on termen beneath apex : cilia grey, round
