THE RED SCALE OF FLORIDA. 31 



pact, melted, as it were, to form the nipple-like projection referred to 

 above. 



"April 28, 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 30, 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 disk with a central nipple. 



"May 3, many of the larvae began to show that they were about to 

 molt, the form of the next stage being visible through the skin of the 

 insect. 



"May 5, nearly all of the larvae had molted ; they were now orange- 

 yellow, with the end of the body colorless. The last abdominal segment 

 now presents the excretory pores which are represented in the drawing 

 of the corresponding segment of the adult female. (Fig. 5.)* The molted 

 skin adheres to the inside' of the little scale, and therefore cannot be 

 seen from the outside. The scales are now pink, or rose colored, with 

 the center white. 



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

 anal segment slightly darker. Most of the scales were now dark pur- 

 ple. On removing an insect a very delicate round white plate was ob- 

 served adhering to the leaf where the mouth parts were inserted. 



" May 18, the male scales were fully grown. At this stage they were 

 dark reddish brown in color, with the center white, and the posterior 

 side, which is elongated, gray. At this date some of the males had 

 transformed to pupae; others were still in the larva state; these larvae 

 were covered with roundish, more or less confluent yellow spots, leaving 

 only the margin colorless ; the end of the body was pale orange. The 

 newly-transformed pupae resembled in markings the larvae just described. 

 Xone of the females had yet molted the second time; their color was 

 deep orange. 



" May 21, nearly all of the males had changed to pupae. It was observed 

 that the last larval skin is pushed backwards from under the scale, to 

 the edge of which it frequently adheres. 



" May 24, none of the male pupae had transformed to the adult state. 



"May 29, it was found that during the five days previous more than 

 one-half of the males had issued, and the remainder, though still under 

 the scales, were in the adult state. It was now forty-seven days from 

 the time the larvae hatched. 



" June 2, no males could be found ; the females were about one-half 

 grown, and were whitish with irregular yellow spots. 



" June 9, eggs were observed within the body of a female. 



" June 17, it was found that one of the females had deposited nine eggs, 

 of which six had hatched. This is sixty-six days from the hatching of
