ceding. It is rather larger ; the hind \\'ings have a pale line 

 across them ; there are no lines of spines ; it has no dusky 

 marks on the front wings, no ovipositor in the female ; 

 the head of the larva is only faintly spotted, and when 

 newly hatched is light greenish. In all of these characters 

 it differs from the preceding and also differs in that the 

 moths mostly leave the chrysalis in the fall. It is found 

 mainly on the elm. Allied somewliat closely to the canker 

 worm is a larger moth. The antennae in this are not sim- 

 ple as in the canker worms but feathered. The female is 

 more slender than that of the canker worm and has a gray- 

 ish colored back, along which are two rows of black dots. 

 The caterpillar is yellow, with ten black lines along the 

 back, and is over an inch long. The moth is, in the male, 

 of a brownish buif color, the front wings with two trans- 

 verse wavy lines, one, that nearest the body, often being 

 indistinct. The hind wings are lighter in shade than the 

 front. The legs are buff and brown. It is one and three- 

 fourths inches across the expanded wings. It has similar 

 habits to the canker worms, feeds on the same trees, and 

 may be checked by the same means. Its scientific name is 

 Hybernaria tilaria, Harris. It feeds chiefly on the Bass- 

 wood or Linden, Apple and Elm. 



There are quite a number of species of Lepidoptera, the 

 larvse of which are called cut worms. Some of these do 

 considerable damage to the buds of fruit trees, more in the 

 West than East, but yet they should not he passed by in 

 this paper. It is usual for larvse of this sort to climb the 

 trees during the night and drop from the buds on which 

 they are feeding to the ground beneath at the approach of
