234 THE entomologist's record- 



It was accompanied by the darker line below it, now wider and more 

 suffused. The pointed projections from either cheek were vinous in 

 colour all over, and were diverted in line rather outwardly from their 

 bases. The markings on the body of the larva could not be said to 

 have altered constructionally in design from their last examination, 

 but they were all larger in execution, and impressed upon the ground 

 colour in a more suffused manner. The ground colour was warmer on 

 the portions between the segments on the skinfolds, and the legs and 

 claspers were all vinous or claret tinted. The dark blotchy markings 

 on and round the excrescences were heavily and l)roadly pronounced, 

 as also were the dark markings on and round the legs and claspers. 

 The anal flap maintained the same form, though it was more thick 

 and fleshy than hitherto, and there also remained the two pointed 

 projections, extending backwards from the extremity of the segment 

 beneath. The setfe on these portions were strongly evident. The 

 spiracles were embedded in raised oval swellings, and were gold- 

 coloured with a lighter edgmg. They still contained the dark vertical 

 slit in the centre, and around them was a glistening and raised copper- 

 coloured skin ridge. Though the larva had attained its final aspect in 

 markings and colour, it had yet a few days of feeding to attain its full 

 size. It was very quiet and sluggish in habit, and sat continually at 

 rest, clinging with the claspers and holding the body at an angle of 

 45'^ to the base. It invariably had the supporting thread spun from 

 some point to the head, and this thread was now of a very tough con- 

 sistency, necessary to the increased weight of the larva, which was 

 considerable. 



It is a cannabalistic larva when kept too crowded, and, like most 

 other species, requires a good deal of room to avoid developing this 

 propensity. It should be mentioned that the seta> on the head, and 

 from the numerous warts on all surfaces of the body, were still in 

 existence. Also that the markings on the ventral area were as before, 

 only that the two dark lines upon it were now almost continuous, and 

 were thicker and darker in effect. The space between them was 

 occupied by a strong accentuation of the reddish tint before alluded to. 



By July 12th the first of the larvje commenced spinning its slight 

 pupal cocoon amongst the dried leaves of the foodplant left at the 

 bottom of the cage, very little feeding ha\ing been done since the last 

 record on the fifth of this month. The intervening time had been 

 spent m sitting motionless at rest, and the movement that was 

 indulged in was nocturnal, to seek the slight feeding necessary. The 

 appearance of the larva had not altered much. It had attained a 

 length of 2iin., and the general tone of its colour was a rich mottled 

 brown. The numerous projections were more pronounced, not only 

 the projecting humps and ridges, but the smaller warts on the dorsal face 

 of the segments, particularly those on the 6th, 7th and 9th abdominal 

 ones. The light elongated spots on the lateral faces of the dorsal 

 ridges, the spiracular projections on abdominal segments 7 and 8, and 

 the outer face of the abdominal claspers had become more distinctly 

 marked, and were of a light sienna colour, while the dark blotches by 

 which they were surrounded were of a deep purplish- brown. The 

 transverse skinfolds between the segments were emphatically incised, 

 and the general aspect of the larva was corrugated to a greater extent 

 than at any time hitherto. While at rest it had a habit of deflecting
