tinge ; spiracles, except first and last which are oval, rather round, 

 small, and edged with black in paler circular area.. There is another 

 pale whitish-yellow line between the dorsal and spiracular, indistinct, 

 also a brown interrupted line below the spiracles on a level with the 

 base of the prolegs. Underside, pale brown ; setae on prolegs, colour- 

 less. The larva now, when at rest, raises its body upwards, posteriorly, 

 forming an obtuse angle from the 7th segment. It eats the whole of 

 the parenchyma and smaller veins from the edge of the leaf. 



After fourth moult. — July 11th. — Head, pale grey-brown, trans- 

 lucent ; clypeus and lines as before. On each lobe there is a purplish- 

 brown blotch with a black tubercle and seta, and below it two other 

 black tubercles and sette forming a triangle with the apex upwards. 

 Antennal tubercle and ocelli purplish-black ; four delicate sette on 

 clypeus. Length, 10mm.; colour, pale brown, translucent, with primrose 

 subdorsal line, and narrow purplish-brown dorsal line less distinct behind 

 where the dorsum is primrose; hump on 8th segment very conspicuous, 

 red-tipped, with reddish-brown furrow ; tubercles, black and con- 

 spicuous on the head and first four segments. On abdominal segments, 

 tubercle i is raised and prominent, becoming gradually less so from 

 segment 1 to segment 8. The other tubercles are comparatively incon- 

 spicuous, with black seta3. On the pro-, meso-, and metathorax and 

 1st abdominal segment, there is a dorsal patch of leaden-grey colour 

 extending laterally to the subdorsal line, and broadest posteriorly, and 

 through the centre of which the purplish-brown dorsal line passes. 

 Spiracles becoming more oval as developed, placed in primrose-coloured 

 spots, forming with the ground colour a broken, indistinct spiracular line. 

 The largest spiracle is on the 8th abdominal segment, and oval ; that on 

 the prothorax, oval, and a little smaller ; and that on segment 7, oval, 

 and smaller still again. The others are very small and somewhat more 

 circular ; all are edged Avith black. The line between the subdorsal 

 and spiracular lines is mottled with greenish-grey and yellow ; the 

 line below the spiracles, purplish-brown and discontinuous. Charac- 

 teristic position when at rest, as before, the angle formed with the 

 body being sometimes nearly right. The anal prolegs generally are 

 extended backwards and outwards. 



After fifth moult. — July 15th, — Eats the softer parts of the cast 

 skin. Length, 20mm ; head, pale translucent green with purplish 

 facial lines, and a dark brown line on the posterior edge of each lobe ; 

 tubercles and setae, less distinct ; clypeus, much flattened ; upper 

 surface of body, pearly-white with faint greenish tinge ; below and on 

 the sides, green, shading oft' into the paler upper surface ; patch on 

 dorsum, greenish lead-colour, widest on metathorax and 1st abdominal 

 segment, narrowing to front of mesothorax and prothorax. On the 

 latter the median purplish line is conspicuous, but only traceable 

 through the patch as a darker shade. Behind it the line is green and 

 thickest in the centre of each segment, becoming faint on segment 10. 

 Segments 2, 3, 4, 5, 6 now appear prominent in the centre, from the 

 raised conical pale tubercles i on each side. These are largest on seg- 

 ment 2 and become gradually less to segment 7. Abdominal segments 

 wrinkled posteriorly, showing traces of three subsegments. On the 

 thoracic segments tubercles i, ii, iii are black, with black setae, and very 

 conspicuous. On the prothorax tubercles i are close together on each 

 side of the dorsal line. Tubercles ii and iii are represented by three
