head is black, with triangular clypeus wedged in between the lateral 

 lobes, towards the lower part of which are five ocelli, two large and 

 three small, arranged in a semicircle. There is a pale marking above 

 the labrum. 



Tlie scnmil stat/e is characterised by change of colour and a 

 longitudinal arrangement of the markings. The larv« during this 

 stage vary in length between -5 and 1'3 cm. (2| to nearly 6 lines). 

 The ground colour is pale yellowish -brown, and often reddish towards 

 the hinder parts. There are five double longitudinal lines, brownish, 

 and mostly tinged with olive-green and waved -the dorsal, two 

 sub-dorsals, and two supra-spiracular. The white spots of the first 

 stage are still visible, but duller. There are traces of a spiracular line, 

 but it is chiefly indicated by the conspicuous white bosses about the 

 spiracles. A black or deep brown velvety mark, often edged in front 

 by orange or red spots, begins to be developed as a blotch on the sides of 

 abdl. segt. 2 ; this ultimately forms the inverted V, characteristic 

 of stage 8. The abdl. segt. 8 is slightly humped, a prominence 

 projecting on each side of the dorsal line, edged externally with dark 

 brown or black, which often extends above the spiracle on abdl. segt. 

 6. The head is obliquely truncated, pale brown, mottled with dark 

 reddish-brown spots and streaks. The suture between the clypeus and 

 the lateral lobes is deeply incised at its upper part, and reddish-brown, 

 and, with a similarly coloured mark on the latter, forms a characteristic 

 W on the face. Above the labrum is a transverse brown line, 

 separated from it by a pale area. Up to this stage the larvae seem 

 inclined to spin a good deal of web, especially when young. They 

 then remain in the web when not feeding, and always spin it towards 

 the light, in confinement. 



Tlw tliird sta(/L' is characterised by a velvety intense black (or dark 

 brown in a few) inverted V on abdl. segt. 2. The length of the larvae 

 varies between 1-3 and 2-G cm. (about G to 12 lines). The colouring 

 is conspicuous for its three different shades ; the darkest, central on 

 abdl. segts. 2-5 (often black on 3, 4), and the palest on abdl. segts. 6- 

 9. It is pale yellowish or reddish-brown, with darker markings. The 

 dark velvety inverted V on segt. 2 is incomplete in front, passing 

 up only to the edge of the dorsal stripe, which is often darker at the 

 point. In a few the velvety mark is complete, and extends into the 

 dorsal stripe. It is often edged in front with orange or red spots. 

 Occasionally, but rarely, there is a similar inverted V on segt. 1, 

 but it is generally imperfect and fainter. On the abdl. segts. 3, 4, 5, 

 there are indications of similar shaped markings, but they are 

 inconspicuous, and never intense nor velvety. There is often a great 

 deal of black suftusion on segts. 4, 5. The sub-dorsal lines begin to 

 disappear, and the dorsal and supra-spiracular lines, hitherto only 

 faintly marked, to put on their black edgings, and in the case of the 

 latter, often black suffusion with frequent discontinuity on segt. 2. 

 The spiracular line is broad yellowish-white, mottled in some with 

 shades of brown, and is conspicuous on segts. 2 and G. On segt. G 

 the pale colour is prolonged in front of the base of the proleg. The 

 spiracles are placed about its centre, except that on the pro-thorax. 

 The underside is dark as far as abdl. segt. G, varying from black to 

 shades of brown, with some paler longitudinal lines, chiefly central. 

 It is pale on abdl. segts. 7, 8, 9,
