female. It appears to me probable that Hewitson's male figure and 

 Distant's female figure refer to one species, which might stand as 

 L. tanita, the locality for which, as given in " The G-enera," p. 422, n. 7, 

 is " Borneo ; India," butrequires to be verified. I have seen no specimens 

 agreeing with these two figures, Hewitson's n. 7, male, and Distant's 

 female ; the species if distinct is very near to L. damajanti, Felder. 

 The species represented in Hewitson's fig. n. 6, female, should, it appears 

 to me, if re-discovered, be named. It is apparently nearest to L. telesia, 

 Hewitson, but has the chrome-yellow area at the apex of the forewing 

 on the upperside much larger than in that species. Mr. Distant has 

 further complicated matters by describing Hewitson's female figure n. 6 

 as a male. The bowed-out inner margin of the forewing in the males of 

 the genus Laxita will at once distinguish them fi-om the females, which 

 have the inner margin straight. The species which Dr. Staudinger 

 figures as " Taxila " tanita, Hewitson, in his " Exotische Schmetter- 

 linge," p. 239, pi, Ixxxvii, male (1887), appears not to differ from what 

 I identify as L. damajanti.

Habitat : Penang; Battak Mountains, N".-E. Sumatra. 



Expanse : c?, 2-0; $ , 1-8 to 2*1 inches. 



Description: Male. Upperside, both wings pure chalky-white. 

 Foreiving with the basal third of the costa reaching to the subcostal 

 nervure dusky ; the costa beyond this, the apex and the outer margin 

 broadly black, the inner edge of this large black area very irregular, 

 it just enters the anterior outer angle of the discoidal cell, is pointed 

 inwardly on the second median nervule, closely approaches the outer 

 margin (exactly as in typical Terias hecabe, Linnasus) in the first 

 median and submedian interspaces, the black area is wider again from 

 the submedian fold to the inner margin; a small portion of the base of 

 the third median nervule prominently swollen, this being a characteristic 

 secondary sexual character in this genus. Hindwing with the costa 

 outwardly broadly black. Cilia of both wings fuscous. Underside, 

 forewing black, the disc crossed by a pure white oblique macular band 

 formed of four portions ; two small and obscure ring-spots in the cell, 

 one on the costa about two-thirds from the base of the wing ; the apex 

 and outer margin decreasingly jDale ferruginous, the inner ed.ge of this 

 area bearing anteriorly a series of four whitish ring-spots ; a sub- 

 marginal series of black dots between the veins ; a rather large oblong 

 dark spot placed obliquely at the anal angle. Hindwing pale ferrugi-
