short hairs, the legs are glossy black with black hairs. The prolegs are 

 red, with black hairs. There is a median line of brown red spots on the 

 middle of each of segments 5 to 1 1. 



Distribution. This species, as stated by Dr Lintner, is known to occur 

 from Maine to Georgia and it has been reported from Indiana, Illinois, 

 Missouri, and Iowa. 



Natural enemies. The caterpillar is well protected with spines but 

 these do not suffice to secure immunity from natural enemies. Dr Lintner 

 states that eight out of 30 individuals he reared were parasitized by a small 

 Ichneumon fly which proved to be Limneria fugitiva Say. He 

 observed that this species spins a cocoon which was found under the 

 elevated central portion of its victim's body, which was clasping a stem by 

 its two extremities. 25 specimens of an undetermined species of Micro- 

 gaster were also reared from the larvae of this insect. Dr Lintner states 

 that their small white elongate, oval cocoons were spun on the outside of 

 the larva and that after a few days the imagoes appeared. The same 

 species was probably bred by the writer in 1902.

Hickory tussock moth 

 Halisidota caryac Harris 



Snow uhilf, black dotted, black tufted caterpillars occur in Jaly, .\ugust and Sep- 

 tember, on the tender leaves of hickor)- and other trees. 



This caterpillar is rather common in New York State, and is a some- 

 what general feeder, though it shows a decided preference for walnut, 

 butternut, and sumac, and is said to be common on elm, ash and linden. 

 Dr Fitch states that he has seen clusters of this caterpillar on the larch and 

 tamarack. It is occasionally present in such large numbers as to cause 

 considerable injury to forest trees in limited localities.
