by three blackish spots, the central one being placed upon the 

 discocellulars ; a diffused indistinct discal brown stripe. Ex- 

 panse of wings 1 inch 7 lines. 



Lycauges, n. gen. 



Allied to Hemerophila ; but the wings with the margins 

 rounded and entire (not dentate-sinuate), the secondaries 

 rather narrower, the palpi slightly shorter, the legs compara- 

 tively longer and more slender. Type- L. Jactea. 



The species of this genus are small, and might by a casual 

 observer be mistaken for Acidalice. 



65. Lycauges lactea, n. sp. (no. 453). 



$ . Creamy white ; wings with marginal and discocellular 

 black dots ; an ill-defined brown stripe, followed immediately 

 by a dentate-sinuate brown line from apex of primaries to 

 middle of abdominal margin of secondaries ; an indistinct 

 sinuated submarginal brown line : abdomen speckled with 

 dark brown and with two or three dorsal black dots on the 

 posterior segments. Under surface creamy white, purer than 

 above; the wings sparsely speckled with brown and with 

 greyish discocellular spots. Expanse of wings 11 lines. 



66. Argidava maculata, n. sp. (no. 513). 



Sordid, shining, chalky white ; primaries with a black basal 

 dot, two spots near the base followed by an arched series of 

 four crossing the basal third, a large spot at the end of the 

 cell, two slightly undulated discal series (some of the spots in 

 the outer series being large), and a marginal series of dots, 

 all black ; secondaries with a grey dot at the end of the cell, 

 indications of a submarginal line and marginal dots of the 

 same colour : front of head black, thorax greyish. Primaries 

 below silvery grey, with barely a trace of any spots ; secon- 

 daries shining white, with markings as above : body white. 

 Expanse of wings 1 inch 1 line. 



67. Ophthalmodes c?-etacea, n. sp. (no. 406). 



Chalky white : wings crossed by two black lines, the outer 

 one dentate-sinuate and postmedian ; a black-edged grey spot 

 at the end of each cell ; two brownish discal stripes beyond 

 the outer black line, the inner one close to it, the outer one 

 submarginal ; the outer border sprinkled with brownish scales ; 

 a marginal series of elongate black spots or fragments of lines : 

 primaries with the inner black line placed far from the outer 

 one near the base, and bounded internally by a brownish
