occasionally either entirely wanting or existing as a continuation of the 

 margin of the basal patch on primaries ; on the upper margin the shade 

 appears to be constant, although sometimes obscured so as to appear a 

 dull gray. 



Similar variations are observable in the abdomen, vermillion and 

 white, red, black and white, and rarely dark brown and white (the color 

 of the wings) ; and in the wings, which may be dark brown sprinkled 

 slightly with gray, and opaque or dull black, and semi-transparent ; one 

 specimen in my collection, with the primaries of the first and secondaries 

 of the latter color, presented a curious appearance ; this was one of two 

 taken from Ampelopsis quinquefolia, the other having both wings thin and 

 silky, and nearly as black as Papilio asterias. The palpi usually agree 

 with the body, as do the legs ; in this case both are dark red. 



Notwithstanding these differences and the wide range in size (4^3 to 

 7^ inches being the extremes of perfect moths in my possession), cecropia 

 agrees so well in general appearance that, aside from the black variety 

 mentioned above, a distinctly marked variety is a rarity, the nearest 

 approach I have seen being in four <J moths from cocoons found on rose 

 bushes, in which nearly all the space on the primaries between the basal 

 spot and the border, is finely flushed with red, which grows fainter out- 

 wardly, the same red flush being continued down the abdominal margin 

 of secondaries, giving the entire moth a reddish hue ; the occurrence of 

 red on the primaries is not extremely rare, but I have never seen others 

 than these with red on the secondaries, except in the border.
