234 THE BUTTERFLIES OF THE 



green ; head emerald-green, the horns reddish, the stripe 

 down the face dark brown. In thirty days they pass 

 the fifth and last moult. 



In some cases they hibernate after the fourth moult, 

 when the color is green ; but twenty-four hours after it 

 changes to yellow-buff and red-brown, the dorsal stripe 

 pale brown ; the bands on each side of a greenish yellow, 

 the side brown, with a dull green line running through 

 it. The head has the face green, the stripes reddish brown. 



The mature larva is 1.2 inches long, slender, the dor- 

 sum arched ; the last segment ending in two long, slender, 

 conical tails, which are rough with tubercles. The joints 

 are creased with six ridges to a joint, the whole surface 

 finely tuberculated, a fine hair arising from each. Color 

 of body green, dorsal stripe darker, on each side of this 

 a pale green band, on the outer edge of which is a yellow- 

 green stripe. On the side a pale green band divided by 

 a yellow line. Head with a long, conical, tapering process 

 from each vertex, the whole head rough with fine tubercles. 

 Color of head yellow-green, the horns red, a brown stripe 

 down the sides. 



In a recent communication Mr. W. H. Edwards gives 

 the following description of the chrysalis : Length .62 of 

 an inch, slender ; much resembles in shape the chrysalis 

 of Debis Portlandia, the head-case more produced than in 

 that species, bevelled to an edge transversely, excavated 

 at the sides ; mesonotum carinated, sides flat, apex almost 

 angular, a very little rounded ; color green ; top of head- 

 case and dorsal edges of wing buff; a buff mid-dorsal 

 stripe, with a buff subdorsal stripe on each side; also a 

 faint lateral stripe of the same color.
