5, 7.8.9 and 13. Owing to the yellow hairs and those 

 tubercles that are yellow, the general impression is of a 

 3^ellow larva, but it is really much darker. The dorsum of 

 2.3.4.5, 7-8. 9 and 12 is very dark, nearly black ; there is a 

 broad yellow line below the trapezoidals, then a broad purplish 

 band ; next a whity yellow line through, or just below the 

 supra-spiracular tubercles ; then another purple band, and a 

 whitish line through the subspiracular tubercles. These bands 

 and lines are a little irregular in outline, giving a marbled 

 effect. Under surface fuscous, head black, the post-spiracular 

 tubercle is still distinct, carrying several hairs. 



In the 4th skin, the larva is of the same type as the 3rd. 

 It now eats the whole thickness of the leaf. The yellow hairs 

 are 3-4 times the diameter of the larva in length, stretching 

 uniformly to both sides, with black tufts on 5, 7.8.9 and 12. 

 Length 13-15 mm. Head black, with labrum and a /\ above 

 clypeus yellow. Larval surface yellow, with purple-black 

 dorsal area, darkest on 2.3.4.5, 7-8-9 and 12, fading into 

 yellow area in marbled reticulations. The trapezoidal 

 tubercles on segments named are black, all others yellow or 

 reticulated with chocolate as the rest of the larva, for reallv 

 the general surface is purple-black or chocolate coloured, with 

 minute yellow circles round the hair points, and these are so 

 large and numerous in the lines of the posterior trapezoidal, 

 the supra-spiracular and subspiracular tubercles, as to result 

 in the impression that the larva here is yellow. The under 

 surface is chocolate coloured. The longest hairs spring from 

 the tubercles, those from the hair points of the general surface 

 are about the larval diameter in length. All the hairs are 

 straight. The anterior trapezoidals of either side rather 

 approximate in the middle line, so that the black tufts 

 appear to be simply dorsal, their double character not being 

 evident without close observation. The black posterior 

 trapezoidals of 7.8 and 9 form very obvious black spots in 

 the posterior trapezoidal pale band. The post-spiraculars 

 are still visible. Some larvae are so dark, that the pale 

 bands are narrow and only the subspiracular one very 

 distinct, whilst the supra-spiracular tubercles are chocolate 

 tinted. On the other hand, the skin of one larva is so pale 

 as to be almost green, with hairs nearly white— the dark 

 (chocolate) dorsal band being barely visible except at the 

 dark tufts — and with two faint darker lateral bands, the hair 

 points being rather paler.
