glabrous than the body coloui-, had two vertical and rather wide dark 

 lines on the face, expanding downwards, and a thinner dark line 

 parallel with it on each cheek. These lines were produced by broken, 

 dark, and reticulated dots. The head was irregularly marked also 

 with isolated dark dotting, though somewhat sparsely, and had many 

 short, light, projecting set<e which were set forwards and outwards. 

 The segments gradually increased in size to the 4th abdominal, where 

 they began to gradually decrease in volume, to finish in a sharply 

 sloping way at the anal end. The fine, light, mediodorsal line was 

 the lightest part on the body, and it was now sharply defined, while 

 the definition of the broad darker tone of the dorsal region, and the 

 broad darker lateral striping had become very evident. The greenish- 

 grey segmental divisions at the skinfolds were more pronounced than 

 heretofore, and the entire larva seemed to be very delicately and evenly 

 peppered with a refined reticulated tracery. The spiracles were each 

 set in a small light space free from this reticulated surface, and were 

 rather deeper in tint than the light ground colour around them, from 

 which they were separated by a firm dark brown, or black, edging. The 

 ventral area was of the light ground colour, and without detail. The 

 legs and prolegs were of the same tint, the latter having a thin grey- 

 black line around them for a pedal ring. The larva led a quiet un- 

 demonstrative life without developing in size much, and only occasion- 

 ally nibbling at the foodplant, until October 5th, when a change of 

 skin was accomplished by the most forward. The alteration in 

 appearance after this change was not great, but those that had hitherto 

 been greyish in colour were more or less fawn-colour like the others 

 had been from the first. The head, after this change of skin, was not 

 different in appearance from what it had been, and the general markings 

 on the body were very similar to those last recorded. The light thin 

 mediodorsal line was still the leading feature, and it ran from the 

 crown of the head to the anal end. Next to this was a fine dark broken 

 line and then for a space of one-third of the distance to the spiracular 

 line was a broad stripe of ash -coloured reticulation on an ochreous 

 ground, which ran from the head to the anal end also. The outer edge 

 of this broad stripe was edged with a broken and rather intermittent 

 reticulated fine line, which was more dai'kly accentuated at the seg- 

 mental divisions than elsewhere. The second third of the space, down- 

 wards to the spiracular line, was occupied by a stripe of about the same 

 width as the first named, only of a lighter tint. Along the centre of 

 this ran a suffused and slightly marked course of reticulation, rather 

 darker than the ground colour. This reticulated wart, however, 

 stopped short of contact with the adjoining darker stripes on either 

 side and left a thin line of the light ground colour which made a 

 suggestion of two light thin stripes, a subdorsal, and a latei'al one. 

 The remaining third of the space between the mediodorsal and 

 spiracular lines was occupied by a lateral stripe of darker ash-coloured 

 reticulation, like the subdorsal stripe above. This was edged with 

 darker, in a broken way above and below, and was scalloped out on its 

 lower edge at the spiracular projections, which made a light crescent- 

 shaped notch in the tint over every spiracle. This lateral stripe of 

 darker tint commenced on the mesothoracic segment and terminated 

 on the 8th abdominal, short of the anal development. The spiracular 

 line was much corrugated and showed a strong crescent-shaped skin-
