spots and a terminal, connected series of still larger ones at the apices of 

 veins 2 to 7. Underside : similar to that in the male, the brown, transverse 

 strigee and spots are more numerous, the costa of the forewing and the 

 median line on the hindwing very prominently brown. Antennae, head, 

 thorax and abdomen as in male. 



Dry-season brood. — Male and female differ only from the wet-season 

 brood in the slightly more falcate apex to the forewing and in the purer, 

 white ground-colour on the upperside; also the terminal margin of the hind- 

 wing in the male has the black markings all but obsolete, while in the female 

 the postdiscal and terminal black markings on the same are smaller than in 

 the wet-season form. Underside : the mottlings of brown strigse and minute 

 spots more numerous and dense. Expanse : 94-100 mm. 



There is a race : australis, Butler, said to replace glaucippe in " Southern 

 India from the Ghauts at Khandalla, south-eastwards to Ceylon " which is 

 distinguished from the typical form, in that the male and female have the 

 inner, black border to the orange patch on the upperside absent ; this re- 

 presented by a few obsolete touches of black scaling. Hindwing : white 

 throughout with only a half-obliterated, subcostal, black spot in interspace 

 7 in the male ; in the female, the postdiscal and terminal series of spots 

 smaller. 



In the Kanara district of the Bombay Presidency, however, it is a fact 

 that H. ylaucippe exists and that forms intermediate between it and australis 

 are also found. There is little doubt that the latter is not even a constant 

 form. 



Egg. — {y. marginal figure). — This is three times as high as broad, narrow- 

 est at base, gradually increasing in diameter upwards 

 to about % the total height, then suddenly narrowing 

 in a curve to apex which is again suddenly narrowed 

 into a low, circular ring of teeth round the micropile. 

 There are 11 or 12 longitudinal ridges which are thin 

 and low, the intervals between each two about equal 

 to the breadth of a ridge, each alternate one reach- 

 ing the apex of the egg as one of the above sharp 

 X 17. teeth, the others disappearing in the surface before 

 \.™« the absolute top; colour shiny white when laid, 

 with a pink shade ; turning yellow later on. 

 Larva. (PI. I, fig. 19). — The body is somewhat fish-shaped, having the 

 dorsal half -segments convex, the ventral flattened ; segments 2-4 are some- 

 what depressed and segments 3-4 are laterally broadened out ; the anal 

 segment is narrowed, somewhat considerably flattened-depressed, ending 

 square with a slight indentation in centre of extreme margin and it over- 

 hangs the anal claspers behind. The body is broadest by far at segment 3. 

 Head much flattened on face, more or less parallel-sided,, rounded over 

 vertex and at base ; surface covered with transparent, conical, bluish tuber- 

 cles, each bearing a fine, short seta, margined laterally by a whitish-yellow 

 band in continuation of the subspiracular band of body ; it is small for the size 

 of the caterpillar and there is very little neck, the front margin of segment 3 

 embracing it completely at the back ; colour glaucous green. Surface of 

 body conspicuously crossed by 7 parallel, depressed lines on most segments 

 (less on the anterior segments, none on anal segment) ; the interval between 

 each two of these impressed transverse lines bears a single row of small, 

 cylindrical, translucent, pointed, blue tubercles, each bearing a fine, short, 

 brown seta ; there are, besides many smaller, conical tubercles ; the tuber- 

 cles along the subspiracular line on segments 3 and 4 are swollen, resembl- 

 ing beads, adding thus to the tumid, lateral appearance of those segments ; 

 the ventrum is smooth. Spiracles small, oval, yellow, situated above the
