SMERINTHUS GEMINATUS 181 



fore, thoiigli tlie subdorsal line was confined to the 

 thoracic segments, the horn was green with a pinkish 

 tip, and the spiracles now were visible, having a red 

 line at each side. 



Six days later they molted for the third time, com- 

 ing out blue-green, with yellow- white subdorsal and 

 oblique lines, and whitish granules. The first pair of 

 obliques was very faint below the subdorsal line, and 

 the sixth pair hardly showed. The spiracles were 

 white, with a blue-black line at each side. Some had 

 blue horns, rough with blue and white granules. Others 

 had pink horns with pink granules. Part of the larvae 

 surprised us by making ready to pupate eight days 

 later, while the others were molting for the fourth 

 time. 



After the fourth molt about half of the caterpillars 

 had pink horns, the rest blue ones. All but one had 

 the last pair of obliques pink, and all lost the pink 

 before pupating. They were like the third molt in 

 other respects. 



The pupge formed three days after the caterpillars 

 stopped eating. They were stout, smooth, and chest- 

 nut-brown, and had no raised tongue-case. 



Those caterpillars which pupated after the third 

 molt were twenty-six days in passing from egg to 

 pupa ; the others were thirty-four days. 



The moths are much more beautiful than excmcatus, 

 which they resemble somewhat. The head is gray, 

 the thorax gray with a patch of dark velvety brown. 

 The tongue is short. The fore wings are falcate and 

 slightly notched, violet-gray or gray in color, and 

 crossed by cyanic, or pale violet, and brown wavy
