row of similar spots across the base of the abdomen ; the tip of the 

 abdomen is very faintly yellow. 



" April 22nd, no important change was noted. 



"April 23rd, it was observed that the scales, appeared faintly 

 reddish in colour with the centre white ; the reddish colour, however, 

 was due in part to the body of the larva, which is now orange-red, 

 showing through the scale. It should be noted that in only a part 

 of the specimens did the cottony mass become enlarged. The 

 greater part of the scales remained until this date of the form, and 

 the cottony spirals have now disappeared, probably having been 

 blown away. 



" April 24th, some of the larvae had become deep orange in 

 colour. 



"April 26th, most of the scales had become deep orange in 

 colour with the central part white; some had at the centre a small 

 nipple-like protuberance ; others still preserved a short tuft of a 

 cottony excretion. This tuft is either removed by wind or otherwise, 

 or it becomes compact, melted, as it were, to form the nipple-like 

 projection referred to above. 



" April 28th, the insects appeared as they did two days ago ; the 

 scales had become very tough, and it was with difficulty that they 

 could be removed from the insect. 



" April 30th, the insects still remained apparently unchanged. 

 Some of the scales were only about one-half as large as others, and 

 still remained perfectly white ; these proved to be male scales. All 

 the scales at this date had an elevated ring on the disc with a 

 central nipple. 



•' May 3rd, many of the larvse began to show that they were 

 about to molt, the form of the next stage being visible through the 

 skin of the insect. 



" May 5th, nearly all the larvae had molted ; they were now 

 orange-yellow, with the end of the body colourless. The last abdomi- 

 nal segment now presents the excretory pores which are represented 

 in the drawing of the corresponding segment of the adult female. 

 The molted skin adheres to the inside of the little scale, and there- 

 fore cannot be seen from the outside. The scales are now pink, or 

 rose colored, with the centre white. 



" May 14th, the insects had become a somewhat paler yellow, 

 with the anal segment slightly darker. Most of the scales were now 

 dark purple. On removing an insect a very delicate round white 

 plate was observed adhering to the leaf where the mouth parts were 

 inserted.
