CHBRRT. LEAVES. 



91. Spotted ekmine moth, Hyphantria cunea, Drury. 



Caterpillars similar to those of the Fall web worm, and like it 

 forming a large cobweb-like nest on the ends of the limbs of the 

 wild cherry, willow and other trees in autumn. The moth a milk 

 white miller with its anterior feet black on their fore side and 

 alternated with black and white on their hind side. Its anterior 

 shanks are black in front and the thighs and hips orange yellow. 

 In the male the fore wings have numerous small black spots and 

 dots which do not appear in the other sex. Width 1.30 to 1.60. 

 The males vary greatly in the number of their spots, and fre-

 fore wings cut across only by the white veins. This species, 

 named in allusion to its fore wings punctatissima or many dotted, 

 by Smith and Abbot, and cunea or wedge spotted, by Druiy, was 

 described by the latter from specimens captured in the vicinity of 

 New-York city, and S. Calverley, Esq., of Brooklyn, to whom I

 informs me it is quite a common insect there. But I have no 

 knowledge of its occurrence anywhere north or west of the High- 

 lands.

 slimy slug worms of an olive brown and blackish color, dull yel- 

 low beneath, tapering and swelled anteriorly, resembling young
