de Nice"ville collection and in my collection from N. E. India and from the 

 Andamans, the shape and extent of this preapical band vary enormously, 

 though no clear dividing line is possible, the band always extends more or 

 less into interspace 4, and, in the case of a female from near Gauhati, is so 

 lengthened as to coalesce with the fulvous discal area in interspace 3. The 

 only constant characteristic I can find in the insular race is that the trun- 

 cate portion of the apex of the f orewing is cut off square or slightly convex, 

 while in all the N.-E. India specimens it is distinctly excavated or con- 

 cave. 



It seems to me that the N.-E. India form should stand as D. bisaltide, 

 Moore, or D. polibete, Cramer ; the Andamans form should be sunk or, at best 

 treated as a slightly differentiated local race andamanensis ; and the Mala- 

 bar insects placed as another well marked local race malabarica. 

 GYANIRIS, (genus). Dalman. 



This is a very widely distributed genus, some representatives being found 

 in every hill tract in India, Burma and the Indo-Malayan region. The 

 Khasi Hills in Assam may, however, in some ways, be considered its strong- 

 hold in India, no fewer than ten of the twenty hitherto recorded Indian 

 species occurring in or near Shillong ; and an eleventh and new one is 

 now described. A few notes on each, with special reference to its 

 appearance in these hills, are appended. 



C. marginata. de Niceville. Only taken July to September but common 

 then. It has not so far been recorded from the tract between Sikkim and 

 the hills of Upper Burma, but will probably be found at suitable elevations 

 in all the Assam hills. 



C. albocserulea. Moore. Local but fairly common, August to October. 

 The first record of its occurrence east of Sikkim. 



G. transpecta. Moore. Decidedly rare ; a spring or early summer species. 



C. puspa. Horsfield. Very rare in Shillong but common at lower elevations 

 in the hills all the year round. 



C. placida. de Nic<5ville. ■ Male very common but only taken in August to 

 early October. Female very rare. One taken in company with a number of 

 males is described, as no description appears in Bingham's work. Costa, 

 termen and tornal area of fore wing very broadly fuscous. Lower part of 

 the cell dull blue but shining in certain lights. Hindwing, upperside, 

 generally fuscous but with a small basal patch of the same dull blue and 

 a slight irroration of blue scales over disc almost to termen. Underside 

 as in the male. 



G. chennelli. de Nic6ville. Very common. A succession of broods from 

 April to October. 



C. victoria. Swinhoe. Recorded from the locality but not taken by me. 



C. imbata. Moore. Fairly common but very local. There are apparently
