the extreme base of interspace 7 and in the spot at the outer end of 

 interspace 7 being subequal to spot in 6 and not larger and more prominent 

 as in C. tvanspectus. 



Phbngaris atkoguttata, Oberthur. 



A good niniiber of both sexes were obtained in the Naga Hills at 7,000 ft. 

 in September. It should occur in Manipur, as it has been recorded from 

 the Chin Hills which is still further South ; but 1 have failed to find it. 



EVBKES PAKKHASIXJS ASSAMICA, n. Sub-Sp. 



Under the above name I propose separating the form of parrhasius from 

 Assam and the Upper Chindwin from the typical form vi^hich occurs in South 

 India and Ceylon ; it differs as follows : — 



Male. Upperside : black border much broader on both wings. Female. 

 Upperside : the discal greyish-blue patch on forewing much reduced, 

 darker and hardly visible ; hindwing rather darker. Vndevdde : similar. 



A parrhasius form of an Everes was recorded by Watson from the Chin 

 Hills under the name of E. dipora, J. B. N. H. S., Vol. X, p. 660. The form 

 from N. E. India and Upper Burma is undoubtedly conspecific with the form 

 from South India and Ceylon and only differs on the upperside as before 

 mentioned. 



EVBKES AKGIADES DIPORA, Moore. 



There are two forms of the Argiades group occurring in Manipur and the 

 Naga Hills. They are probably dipora, Moore, and diporoides, Chapman, as I 

 have similar specimens from the N. ¥/. Himalayas, the habitat of these two 

 forms. I however cannot identify them with certainty as I have not Chap- 

 man's description of diporoides by me and Moore's description of dipora fits 

 both forms. 



In the first form the c? is dull blue with a narrow black terminal border. 

 It is variable in size ; the dry-season-form being sometimes very small, but 

 the wet-season-form appears to average considerably larger than the second 

 form, the S of which is much brighter blue with a much broader black 

 border to the termen. 



There should be no difficulty in separating the dipora and parrhasius 

 groups as the undersides are quite different. In the dipora group all the 

 spots on the underside are round and black. In the parrhasius group the 

 only spots that are round and black are the tioo in spiace 8, one in the cell and 

 one on the abdominal margin of the hindwing ; the other spots are somewhat 

 linear and pale grey. 



Castalitjs P.OXUS ROXANA, de N. 



C. ro.vana is undoubtedly a race of C. roxus and was described from the 

 extreme dry-season-form. There are three well marked forms. 



(a) The extreme dry-season or typical form. (6) An intermediate form which 

 has the white bands narrower and a deep black border which has its inner 

 edge slightly encroached upon by the white discal band. This form is 

 almost exactly similar to a specimen of C. roxus I have from Upper Tenas- 

 serim. (c) A wet-season-form with white bands very narrow and black, 

 outer margins broader, its inner edge more even. 



Numerous specimens were obtained in Manipur both in the Eastern and 

 Western Hills and a few at Nichuguard in the Naga Hills. Wet-season- 

 forms were taken from April to November ; intermediate forms in December 

 and again in March ; dry-season-furms from December to February.
