2 LEPIDOPTERA IN DIG A. 



Dri/-!icason Form. Mn\e. Upperside. Foreicing with a much narrower bhick- 

 scalecl apical-marginal baud, and a more or less obsolescent discal spot, the latter 

 being sometimes quite obsolete ; the discocellular black spot much smaller. Under- 

 side similar to ivet-season iorvci, the apex of foreicing, and the hindiving, being much 

 paler brown scaled. 



Female. Unknown. 



Expanse, S 2^ to 22 inches. 



Habitat. — Lower Burma ; Teuasserim ; Malay Peninsula. 



Distribution. — The type specimens described and figured by Mr. H. Grose- 

 Smith were taken by Col. C. H. B. Adamson at Thoungya Sekkan, Upper Tenasserim, 

 ■who writes " numerous specimens were taken by me on April 24th " (List p. 44). 

 Col. Adamson also obtained S2Decimens in the same locality on February 18th. We 

 have examined the types, and other specimens, both of the ^oet and dry form, and we 

 find that all prove to be males, as is evidently the fact by their having the intromittent 

 organ exserted at base of the anal valves. In Mr. Grose-Smith's collection is a 

 male of the tret form, taken by Mr. T. C, Hauxwell in April, in the Dounat Range, 

 Middle Tenasserim ; Dr. Leonarda Fea obtained it in the Karen Hills. 



The type of Indroides, Hagen, is recoi'ded from Perak, Malay Peninsula.
