ATTACUS GLOVERI 249 



ate well, excreted well, and suddenly were found dead. 

 After the first death of this kind we separated them, 

 having but one or two in each large tin ; but all our 

 care was of little use, and very few survived and spun. 



They fed for sixteen days before spinning, then 

 spun very slowly, and the cocoon was not like those 

 which gave the parent moths, being dark brown like 

 cecropia cocoons, and of a rounder, fuller shape. This 

 was probably due to the difference of food-plant. 



The life from egg to cocoon was thirty-six days. 



The caterpillars closely resemble cecropia larvae, and 

 the moths have a general resemblance to cecropia, 

 though smaller and far more beautiful in coloring. 

 The head, thorax, and legs are of a deep, rosy wine- 

 color, the collar being white. The abdomen is white 

 with black marks in some specimens, white, black, and 

 wine-colored in others, the amount of each color vaiy- 

 ing very much. The upper side of the wings is suf- 

 fused with rich, rosy wine-color, the shade varying in 

 different specimens, and has a white line across both 

 wings; the borders are of clay-color, and each wing 

 has a white crescent with a surrounding line of tan- 

 color, then a line of black. The under side of the hind 

 wings is of a silvery gray, and that of the fore wings 

 is of deep wine-color. 



The males are polj^gamous and mated with A. an- 

 gulifera and A. promethea as well as with their own 

 species. They are very active and excitable, more so 

 than any other attacine moths we know, and the 

 females protruded their ovipositors before their wings 

 were half spread. They are slow in developing after 

 emerging. Some moistened the end of the cocoon
