sienna brown, with two pairs of shorter lateral white tufts ; a pair of whitish 

 tufts near the end of the body ; head yellowish brown ; a row of lateral 

 black spots above the base of the abdominal legs ; length 30 mm. 



The adult is a very pale yellowish brown moth [pi. 44, fig. 4]. 



Rusty tussock moth 



Notolophns antiqua Linn. 



A black-headed, yellow or white-tufted caterpillar with a lateral black hair pencil on 

 each side, feeds on most deciduous forest trees. 



This hair-tufted caterpillar resembles the much better known and very 

 destructive larva of the white marked tussock moth, Hemerocampa 

 leucostigma Abb. & Sm., and maybe separated therefrom at once by 

 its black head and from other allied forms by the presence of the lateral 

 black hair pencil about midway of the body. This species has been 

 received on several occasions from northern parts of the State, where 

 it seems to be slightly more abundant than farther south. We have yet 

 to learn of its causing serious injury. Dr Lintner records taking this 

 species on low willows at Keene Valley N. Y. 



Dark tussock moth 



Olene achatina Abb. & Sm. 



A black-headed caterpillar clothed with grayish hairs and with two black hair pencils 

 on the second segment, and square tufts on segments five to 12, feeds on various deciduous 

 forest trees. 



This species is allied to the rusty tussock moth, Notolophus 

 antiqua Linn, and has somewhat similar habits. It has been recorded 

 as feeding on oak, hickory and wild cherry, while Dr Smith states that in 

 New Jersey its larva occurs on the usual orchard trees and also oak, hickory 

 and chestnut.
