THE PINE HAWK. 35 



chrysalis found near Horham Rectory, Wickham Maiket, 

 SutTolk. In 1878-9, caterpillars were met with at Leiston, 

 Suffolk ; the moth was found in the pine woods around Alde- 

 burgh, 1 88 1, and as many as forty specimens were taken in 

 July and August, 1882, and rather more than twenty in August, 

 1919. In 1895, Lord Rendlesham, when driving through the 

 tir woods in the neighbourhood of Woodbridge, noted two 

 specimens in almost the same spot where he had taken some 

 moths in 1892-93. Mr. F. Mellusson, writing from this district 

 (August 2, 1895), stated that fifteen specimens had been taken, 

 and that others could have been captured; also that about 

 one hundred larvae were then feeding in confinement. He 

 also mentioned that 1895 ^^as the fourth year out of five that 

 the insect had occurred there. A male moth was found at rest 

 on an oak trunk near Southwold, Suffolk, on July 29, 1900. 

 On August 13, 1906, the Rev. A. P. Wallet- saw a worn specimen 

 on a pine trunk in the rectory garden at Woodbridge. He also 

 noted a pupa on September 30, 1917. (Plate 12, Fig. 2.) 



The mature caterpillar, which feeds on pine needles, is green, 

 with a yellowish-edged reddish line along the middle of the 

 back and a creamy line on each side of this ; the interrupted 

 line below the reddish spiracles is yellowish or ochreous. 

 Head yellowish brown ; horn blackish brown ; both are glossy. 

 It enters the earth and there turns to a reddish brown chrysalis ; 

 this is rather glossy, somewhat darker above than below, and 

 appearing blackish between the rings; the rough "tongue" 

 sheath is short and attached throughout to the case ; the tail 

 spike is roughened, and has a blunt point on each side of it 

 (Plate II, Figs. 3, yi). 



It has been recorded that caterpillars hatched from the egg 

 early in August, pupated in October, and the moths emerged 

 the following May-July. 



The perfect insect sits upon tree trunks, chiefly pine, often 

 well within reach, although sometimes its position is fourteen or
