70. LYCil'^NESTHES BENGALENSIS, MoOrC. 



Rare, occurs throughout the year. 



71. Nacaduba ardates, Moore. 

 Rare. Occurs amongst bushes. 



72. Catochkysops strabo, Fabricius. 

 Common. 



73. Catochrysops cnejus, Fabricius. 

 Common. 



74. Catochrysops pandava, Horsfield. 



Common. In April and May I have found the larvae swarming on 

 the hardly-open shoots of Gycas revoJuta^ thereby utterly destroying the 

 appearance of the plant for the year. There is also a brood out in the 

 rains. 



75. Catochrysops bengalia, n. sp. 



Male. Upperside violet-blue ; the cilia dusky, Forewing with the 

 outer margin narrowly black. Hindwing vfith a marginal series of 

 dusky oval spots, the third from the anal angle larger, black and round ; 

 an anteciliary black line ; tail dusky with a v^hite tip. Underside 

 gray ; the cilia gray spotted with dusky. Forewing with a white-bor- 

 dered brownish spot closing the cell, a curved discal series of joined 

 similar spots, two series of marginal lunules ; a black anteciliary line. 

 Hi^idwing with four subbasal dusky spots surrounded with white, A 

 much curved discal series, the upper spot on the costa usually the most 

 prominent, and a spot closing the cell ; marginal lunules much as in 

 the forewing, but more prominent ; a small black spot faintly crowned 

 with orange in the first median interspace and three very minute anal 

 ones beyond it, all four sometimes absent. In some specimens the discal 

 series of spots on the forewing are much elongated towards the middle of 

 the wing, and in all the specimens I have seen, except two from Sikkim, 

 the spots on the disc and the one closing the cell of the hindwing have 

 coalesced, forming an irregular brown patch in the middle of the wing, 

 which patch sometimes reaches and includes the subbasal spots. 



Female, Upperside shining iridescent violet-blue, Forewiyig with 

 the apex widely and the outer margin decreasingly black, E-indiuing 

 with the costal margin dusky. Otherwise as in the male. 



Expanse : $ ? , 1"2 inches. 



Near to G. pandava, Horsfield, Male smaller than that species, of 

 a paler shade of blue ; differing on the underside, in the coalescing of the 

 discal spots, and the anal spots of the hindwing being much smaller or 

 absent altogether. The female on the upperside is of quite a different 

 shade of blue, which colour reaches to the costa and much nearer to the 

 margin in the forewing, and covers all the hindwing except the costal
