close to tlie base of a larger leaf. No trace of any of the 

 work of the larva in the interval can be found. 



The larva found on 17th has thickened its web and 

 pellets of frass are conspicuous on its upper surface. The 

 larva can still be faintly outlined beneath. The first larva 

 is quite invisible. 



Oct. 22nd. The three inhabited plants are not looking 



flourishing ; two which have the largest green centres 



have the cocoons as last described, the third, however, has 



only a small central bit of green, and there is a new and 



larger cocoon on the other side of this fiom the original 



... 

 one, that does not look much different ; the new cocoon is 



still imperfect, and one glimpse was got through it of the 



black head of the larva moving about and apparently 



spinning, and again of tlie body of the larva, of which no 



details appeared, but it was decidedly larger and of a flesh 



tint. It is unfortunate that the larva was not seen when 



on the move and transferred to a better plant and a 



description of it taken. The presumption is that it is 



now in its third skin, 



Oct. 24th. This larva is found crawling about outside 

 to-day, it is a question whether it is not merely in second 

 stage ; it is just fully 2 mm. long, head black, general 

 colour flesh-colour, made up of white and reddish markings. 

 The tubercles I and II are united on one base, II the 

 longest hair, and has one secondary hair behind it, one or 

 two tubercles seem to have another secondary hair. No 

 other secondary hairs to be found. Base of hairs and 

 spiracles dark, first thoracic plate has a white central line 

 with black line on each side and a black spot further out. 



Each tubercle is surrounded by a white area, between 

 is dull red ; the red area has fine skin points which are 

 absent or very indistinct in the white areas. Haii s slightly 

 clubbed. III bent forwards, front upper of IV -f V directed 

 rather forwards, shorter than the posterior, which is directed 

 outwards. 



The white and red is perhaps better described as in 

 longitudinal lines, a red dorsal one, then a broad white, 

 including I and II, then a red one which has various 

 processes, so that the description of white circles round 

 tubercles results from these takinof circular arcs, with 

 tubercles, spiracles, etc., for centres. But there are other 

 centres with Avhite that are not at present occupied by 

 tubercles. On first segment is a little longitudinal stripe
