and Southern India. The figures 57 and 57a on Plate II are too red, 

 the male too dull blue above and not blurred enough on the under- 

 side ; the female (57a) has the colouring far too unequal on the 

 upper and far too light on the underside. 



It is best to append a description of the South Indian variety or species — if it, 

 indeed, merits the name — christened coruscans by Wood-Mason and de Niceville 

 in 1880 from South India. As it is the South Indian species or variety, the 

 description appended is based on Avhole rows of fresh insects and is taken direct 

 from them without reference to the original one contained in the Journal of the 

 Asiatic Society of Bengal, vol. xlix, pt. 2, p. 234, n. 54 (1880) ; which is, besides, 

 not available for reference at the present moment. 



167b. Arhopala coruscans, Wood-Mason & de Niceville. — Male Upperside : 

 pm-plish-blue, lighter and less intense in bright sunlight than the beautiful, 

 shining morpho-blue of amantes. Fore wing : the black borders are here ex- 

 tremely narrow, not more than O. 5 mm, excejDt at the extreme apex where the 

 black broadensout slightly. There is a slight greenish tinge at the extreme base 

 of the wing. There is a slight fringe of greyish hairs along the inner margin. 

 Hind wing : the black border of the outer margin from vein 7 to vein 1 as narrow 

 as on the fore wing ; above vein 7 and below vein 1 is blackish- brown except at 

 the extreme base where the blue invades the inter spaces ; the actual inner margin, 

 the body-groove is much lighter brown. There is no anal lobe and the tail at 

 the end of vein 2 is short and broad (3 mm. or slightly more, by 1 mm.) and 

 blimtly pointed ; black with a small, greyish tip. There is also a very short 

 l^roduction of the cilia at the ends of veins 1 and 3. Underside : fore wing : 

 rufous-brown with the intervals between the terminal markings and the post- 

 medial band as well as between that band and the medial-markings, rufous-grey, 

 much lighter in colour ; the rufous-brown, slightly darker markings exactly as 

 in amantes band for band and spot for spot except that the spots in and at the 

 end of cell are larger and bordered in their upper halves by very light bluish- 

 green scales which stand out very conspicuously from the rufous back-ground ; 

 the postmedial band is also much evener than in the other species and there is 

 never any streak in intersjoace 1 between the postmedial and medial markings : 

 that interspace is here grey. Hind wing : brighter rufous-brown than on the 

 fore wing, with aU the markings of amantes visible as blurred spots and bands 

 difficult to make out excejDt that the double row of black, lunular, subterminal 

 markings in the anal region are here replaced by brown ones and there is only a 

 mere indication in interspace 1 of a sprinkling of light bluish-green scales 

 where the spot should be ; there is an indistinct Avash of darker rufous-broAMi 

 than the gromid-colom* from base through the cell to the terminal margin 

 where it broadens out. Cilia of both wings above and below brown with the ends 

 greyish — Female. Upperside : similar in colour to the male with the bases of 

 wings more plentifully greenish. The broad black costal and outer margins 

 similar to those in amantes except that, always, the posterior, terminal breadth 

 is less than in that species ; the veins all blackish (which is not the case in the 

 male) ; the abdominal margin very light in colour. Underside : exactly as in the 

 male. Cilia as in the male. In both sexes :antemiai brown, with a longly, 

 graduated, rounded club which is tipped with orange and, in the male, sprinkled 

 with white scales below • palpi broA\'n, lighter below ; Irons and head brown ; 

 thorax above blue-green, below light brown ; abdomen broAvn. Expanse : male, 

 50 mm. ; female, 60mm. 



168. Arhopaia amantes, — Hewitson. Male. Upperside: both wings bril- 

 liant morpho-blue, the base narrowly greenish with narroAV black borders to the 

 costa and outer margin ; the veins blackish. Fore wing : the black border of 

 costa narrowing from base to middle ; the inner margin with a slight fringe of
