latter would most surely devour the little caterpillar immediately it 

 made its appearance. The food-plants of the larva are Mangifera 

 indica, L., the mango and Anacardiam occidentale, L., the cas- 

 hew-nut tree. The dorsal yellow band of the larva lying on the 

 midrib of a leaf so exactly corresponds with that midrib, the filminess 

 of the feathered processes and colour of the whole so resembles the 

 leaf-surface that the caterpillars are very difficult to spot. 



44. Euthalia nais, Forster (PI. C, fig. 16). — Male and female : upperside 

 tawny yellow; base of both wings dusted with fuscous scales ; cilia black, alter- 

 nated with white. Forewing with the following black markings : a transverse 

 line below apex of cell, an oval transverse spot beyond encircling a small yellow 

 spot, a broad, short, oblique discal bar and an angulated postdiscal lunular 

 band ; the costa narrowly and the termen shaded with black. Hindwing : a 

 comparatively large triangular patch below the middle of the costa, a post- 

 discal evenly curved series of spots and a broad band along the termen black. 

 Underside dark ochraceous red, Forewing : base shaded with fuscous black, 

 two spots at the base of cell and a transverse line beyond crimson-pink, edged 

 with black ; a very broad oblique discal band angulated downwards below 

 vein 4, bordered posteriorly by a lai-ge black spot on the inner side and out- 

 wardly and anteriorly by an oblique broad black band followed by four 

 anterior obliquely-placed ochraceous- white spots and beyond by a very narrow 

 lunular black band bent downwards below vein 6. Hindwing : a crimson short 

 line at extreme base, two crimson black-bordered spots in cell ; a comparatively 

 broad and transverse discal white band often broken up into a large spot 

 below middle of costa, with two or three spots in line below it ; finally a post 

 discal series of small black spots. Antennae black, bright ochraceous at apex ; 

 head, thorax, abdomen tawny-red above, brown, shaded with crimson-pink 

 below, Exp. 58 — 70mm. 



Egg. — Is hemispherically dome-shaped ; green in colour; shiny, with the 

 tops of the cell-walls brown. There are 7 hexagonal cells immediately round 

 the apex where there is a punctulate space as large as the largest cell ; there 

 are 7 rows of cells from top to base but these rows are not regularly horizontal, 

 the two last rows at base are small cells and have no brown tops to walls ; all 

 cells are concave and smooth ; there is a colourless, thickened hair-like process 

 surmounted by a brown pointed hair at each intersection of cell- walls : the 

 process including hair not being quite as long as breadth of largest cell, B. 

 l*5mm,; H, a little less. 



Larva. — In shape and style the larva is the same as those of Doplila and 

 other Euthalm. It has the same long, horizontal, feathered processes to 

 segments 3-12, all lying with the points on the leaf surface when the larva is 

 at rest. Head piriform, face convex with a small triangular clypeus ; covered 

 all over with short, soft white hair, colour green, clypeus bluish, jaws colour- 

 less with dark tips, eyes black. Head larger than segment 2. Anal segment
