 Cp'|3SUS LIGNl'PEJRDA. Goat Motll. 



The caterpillar of the Goat Moth is 

 most destructive to the wood of fruit- 

 trees, though the elm, oak, willow, 

 poplar, and walnut, also, are liable to 

 its attacks. It is the COSSHS liyniperda 

 I of some naturalists, and the Bumlyx 

 and Xyleutes cossus of others. The 

 j caterpillar measures more than four 

 ' inches in length, is smooth and shin- 

 ; ing, beset only here and there with 

 single short hairs. It is dark red on 

 the back, and the breathing-holes si- 

 : tuated at both sides are of the same 

 ! colour. The sides and lower part of 

 the body are flesh-coloured ; the head 

 ! is black, the first segment also marked 

 : with black above. After remaining 

 j more than two years in the larva state, 

 ! and casting its skin eight times, the 

 | caterpillar becomes of a light ochrish- 

 I yellow hue, shortly before becoming _ a 

 chrysalis, which usually takes place in 

 spring, when it makes a strong cocoon 

 of chips of wood and small pieces of 

 bark, which it has gnawed off. The 

 chrysalis is yellow, and the segments 

 i are deeply indented and capable of 

 I much extention ; its back is furnished 

 ! with strong pointed spines, sometimes 

 ; of a reddish brown colour. The cocoon 

 i is situated immediately within the open- 

 j ing in the tree, so that the pupa, when 

 arrived at maturity, can press itself half 

 : out of the hole when the shell bursts, 

 | and the moth comes forth usually in 

 ! the month of .Tune or July, after having 

 ' reposed in the pupa state for an inde- 

 ' finite time. When at rest the wings 

 i are folded together over the back in 

 j the form of a roof; it. sits quietly in 

 the day-time on the stems of trees, and 

 is difficult to be distinguished on ac- 

 count of its grey colour. Its wings 

 measure, from one tip to the other, 

 nearly three inches, and many speci- 

 mens more than this : the female i , 

 usually larger than the male. The 

 fore-wings are ashy white, clouded with 

 brown, especially across the middle, and 

 marked with very numerous streaks, 

 like net - work ; the hind-wings are 

 brown. Thorax ochrish in front, pale
