78 ISOTEINON. 



August and subtest&ctus only in April, so possible they are seasonal varieties 

 of one another. Mr. Moore's figure of atkinsoni agrees very well with 

 my specimens, and Mr. Elwes' figure (Trans. Ent. Soc., 1888, pi. xi, fig. 

 96), agrees very well with my specimens of subtestaceus, except that the 

 series of spots on underside of hindwing have been omitted. Moller also 

 considers the form figured by Elwes to be the spring blood of /. atkinsoni 

 which would agree with the dates of my captures noted above. Mr. Elwes 

 also states that /. khasianus of which he has seen the type seems to be the 

 present species. In collections Indian Museum and de Niceville. 



112. ISOTEINON SUBTESTACEUS, MOORE. 



Isoteinon snbtestaceus, Moore, P. Z. S., 1878, p. 844. 



" Male and female. Upperside dark olive-brown ; cilia cinereous, 

 brown, with a brown inner line and indistinct bars : forewing with a 

 semi-diaphanous spot at end of the cell, a curved series of three subapical 

 contiguous spots, and two larger contiguous spots on the disc. Underside 

 brownish-ochreous, grey-speckled : forewing with the basal area below the 

 cell and the disc fuliginous-black ; spots as above ; male with a black 

 tuft on hind-margin : hindwing with a curved discal series of six small 

 white spots, and four subbasal spots, the two low r er of the latter being 

 contiguous, the third at the end of the cell and the fourth above the cell. 

 Palpi and body beneath ochreous white ; legs brownish ochreous, allied to 

 /. atkinsoni, from Darjeeling. 



Expanse : if inches. 



Habitat : Ahsown, (Tenasserim.)" (Moore, I. c.)

113. ISOTEINON KHASIANUS, MOORE. 



Isoteinon khasianus, Moore, P. Z. S., 1878, p. 693. 



" Male. Upperside glossy ochreous-brown ; cilia brownish-cinereous, 

 with a brown inner line and indistinct bars : forewing with a small silky- 

 white semi-diaphanous spot at end of the cell, three contiguous spots before 

 the apex and two on the disc. Underside rufous-brown ; forewing marked 

 as above ; a small tuft of black hairs on middle of hind-margin : hindwing 

 grey-speckled, a small white spot at the end of the cell, and a median 

 discal curved series of white dots, each surrounded by dark brown. 



Expanse : i T l (T inches. 



Habitat : Khasia Hills. 



A specimen of what I believe to be the female of this species is in the 

 collection of Dr. Staudinger, but without a locality (though probably 

 Indian). It differs from the male above described in having the spots on 

 the forewing slightly larger, the cell spot transversely elongated, and in 

 there being an additional spot below the two on the disc. It is also greyer 

 on the underside ; the hind-margin on the forewing has a very pale border ; 

 and the hindwing has no perceptible white dots." (Moore, I. c.)
