GrEKYDXJS BOISUUVALI, Moore. 



A male and female taken at Nichuguard in October antl November and 

 several males at Sebong, Manipur, in November, January and February. 



Gerydus longeana, De N. 



Occurs commonly in the Manipur Valley itself. Many specimens were 

 also taken at Sebong and on the Cachar Road, Western Manipur Hills ; also 

 taken at Nichuguard, Naga Hills. 



There are three well defined forms of this species. 



(1) The loet-season-form, the males of which cannot be distinguished 



from G. boisdicvali taken in the dry-season, the females can how- 

 ever be easily separated by the broad continuous white discal 

 band on forewing. Taken from May to November. 



(2) An intermediate dry-season-form, agreeing with Bingham's descrip- 



tion, which flies from October to May. 



(3) An extreme dry-season-form which varies from very pale brown with 



dashes of white to almost pure white ; taken from November to 

 March. 

 Some specimens of the wet-season-forin agree with the description of 

 Gerydus irroratus, var. assamensis, Doherty. 



Allotinus dkumila, Moore. 



Decidedly rare in Manipur ; a pair taken on the Irang River, Western 

 Manipur Hills, in February. Up till 1913, 1 had only managed to obtain 

 one female in the Naga Hills, but in 1914 during March, April and May my 

 collectors managed to obtain a male and twenty-one females at Nichuguard. 

 The males appear to be very rare. 



Allotinus stjbviolaoeus, Moore. 



A female taken on the Cachar Road, Western Manipur Hills, in November 

 and a male and three females in December. 



This is an interesting capture as it has not been previously recorded 

 further North than S. Burma. 



De Niceville calls the Burmese form A. alkamah, distinguishing the same 

 from the Javan form, true subviolaceus, in having the violaceous area on 

 upperside in the male of greater extent. 



'J'he conspicuousness of the violaceous area on both wings of the three 

 females now before me is variable ; one female has it dull like the male, 

 whilst the other two have it bright and clear.
