208 TIIE BUTTERFLIES OF THE 



73. LIMENITIS ARTHEMIS, Drary. 



Expanse of wings from 2.5 to 3 inches. 



Upper surface black, a white band crossing both wings, 

 that on the fore wings curving from the middle of the 

 costa to near the posterior angle, from which place it is 

 continued across the hind wings to above the anal angle. 

 The fore wings have a white subapical spot and two 

 marginal rows of faint green lunules. The hind wings 

 have the lunules more distinct, and inside them a row of 

 fulvous spots. 



The under side is fulvous brown, marked as in L. Ur- 

 sula, except that in this the white band of the upper 

 surface is repeated. 



This is a dimorphic species, the two forms at first 

 supposed to be distinct species, but Mr. Edwards has 

 reared both forms from eggs deposited by the same 

 female, which proves them to be only forms of the same 

 species. The above description applies to the one known 

 as dimorphic form LAMINA, Fab. The other, dimorphic 

 form PROSERPINA, Edw., may be known by the white 

 band of the fore wings being obsolete on its anterior 

 half, or by there being at most only a whitish stripe oc- 

 cupying some part of the position of the band on the 

 other form. 



The egg is grayish green, dome-shaped, with the whole 

 surface covered with six-sided reticulations, from each 

 angle of which arises a short, tapering, white spine. 



The young larva hatches from this in from seven to 

 nine days. It is yellowish brown, covered with fine 

 tubercles, each supporting a fine club-shaped hair. The 

 young larva is said to eat away the leaf on both sides of
