<$ . Primaries pale sulphur-yellow, crossed by irregular dentate-sinuate black lines and 

 by black subbasal spots, also with a series of large black costal spots, and with the fringe 

 interrupted by black dashes, almost exactly as in the European L. monacha : secondaries grey, 

 slightly brownish towards the base and abdominal margin ; costal area crossed by white 

 patches ; two curved parallel discal series of white spots ; a marginal series ; fringe dusky, 

 interrupted by large snow-white spots : thorax pale sulphur-yellow, spotted with black ; 

 antennae dark brown ; abdomen rose-red, with whitish anal tuft. Primaries below with the 

 basal two thirds partly greyish brown, obscuring to a certain extent the dentate-sinuate lines, 

 the latter are also all brown instead of black ; costal border spotted with black as above : 

 secondaries brown, the spots of the upper surface sharply defined, cream-coloured ; base 

 cream-coloured, crossed by an oblique brown stripe : pectus black ; tibiae fringed with cream- 

 colour ; tarsi cream-coloured, banded with black ; venter cream-coloured, with the sides, 

 anterior margins of the segments, and anal tuft blackish. Expanse of wings 2 inches 2 lines. 

 $ . Primaries above cream-coloured, with all the markings much more slender than in 

 the male, but similar in character : secondaries snow-white ; two subapical costal dashes, an 

 indistinct curved line on the discocellulars, and traces of a submarginal sinuated line grey : 

 thorax cream-coloured ; the palpi, a spot at the back of the head, the centre of the collar, 

 a dorsal longitudinal stripe on the thorax, a spot on metathorax, and a spot on each 

 tegula black : abdomen ochreous, white at the base ; the last three or four segments with 

 central brown and lateral black spots. Wings below white, with cream-coloured costal 

 borders : primaries with all the markings upon the basal two thirds ill defined, only seen 

 through the texture of the wing, excepting upon the costal border, where they are black : 

 secondaries with the subapical and discocellular markings well defined and brown : body 

 below cream-coloured ; legs black, the tibiae fringed and banded with white ; venter ochreous, 

 spotted with black at the sides. Expanse of wings 3 inches 5 lines.

Lymantria superans. (Plate XC. figs. 10 & 11.) 



2 . Lymantria superans, Walker, Cat. Lep. Eet. iv. p. 876. n. 10 (1855). 



$ . Similar to the male of the preceding species, but the primaries with the ground- 

 colour pure white instead of sulphur-yellow ; the secondaries with the white spots, excepting 

 on the fringe, extremely ill-defined : thorax cream-coloured, spotted with black ; abdomen 

 rose-red, with a dorsal series of dusky spots. Primaries below much less obscured by brown, 

 excepting upon the costal border, which is brown to the end of the cell : secondaries white, 

 the abdominal border sordid ; an irregular curved dentate-sinuate band from the costa to the 

 median vein ; a curved dentate-sinuate stripe beyond the cell, the costal border beyond the
