ments blue-green, sparsely granulated with yellow. 

 The rest of the body was yellow-green, densely granu- 

 lated with yellow. The head was shaped like an apple- 

 seed, though broader at the large end, and had two 

 large yellow granules at the apex — also like T. mo- 

 desta. The first segment had two shorter yellow gran- 

 ules on the dorsum. The caudal horn was longer, 

 pinkish at the tip, and very rough. The legs and props 

 were green as before. The oblique and horizontal 

 lines were of yellow granules set close together. A 

 day or two later the horns became bright carmine, ex- 

 cept on the sides, up which the last obliques extended. 

 The legs were red at the tip, and a few caterpillars 

 had small bright red spots on the fifth segment, one 

 on each side of the dorsum. 



The second molt was five days later. The first brood 

 now had all the yellow and red markings, and the sec- 

 ond was as before, except for faint yellow face-lines, 

 denser granulation, and more red spots, the number 

 varying from two to twelve per caterpillai*. 



The first brood molted in six days, the second in 

 four, this time. The yellow granules on the apex of 

 the head had become reduced to dots. The face-lines 

 were of yellow granules. The bodies were still granu- 

 lated. The horns were pale red in front, yellow behind 

 and at the sides, short, triangular, and rough. The spir- 

 acles were red. The legs had red tips. There were 

 from two to forty-eight red patches on the body. Two 

 crawlers had their horns blue-green with yellow sides, 

 and no red. Several found on willow had blue horns 

 with red sides, and forty-eight very red spots, the last 

 pair of obliques being suffused with red also. 



Two days later all the red disappeared from the
