came to their growth about the last of July, at which 

 time they were both without a vestige of green. The 

 grouucl-color was dirty yellowish, especially at the sides. 

 Each segment was marked transversely with six or seven 

 slightly impressed fine black lines, and longitudinally 

 with wider non-impressed dark-brown patches, alternat- 

 ing with each other, and giving the worm a checkered 

 appearance. These patches become more dense along 

 the subdorsal region, where they form two irregular dark 

 lines, which on the thoracic segments become single, 

 with a similar line between them. There was also a 

 dark stigmatal line with a lighter shade above it, and a 

 dark stripe running obliquely downwards from the pos- 

 terior to the anterior portion of each segment. The 

 belly was yellow with a tinge of pink between the pro- 

 legs, and the shiny tubercle at the tail was black, with a 

 yellowish ring around the base. The head, which is 

 characteristically marked, and by which this worm can 

 always be distinguished from its allies — no matter what 

 the ground-color of the body may be — is slightly rough- 

 ened and dark, with a lighter broad band each side, and 

 a central mark down the middle which often takes the 

 form of an X- This worm does not assume the common 

 Sphinx attitude of holding u^d the head, but rests 

 stretched at full length, though if disturbed it will throw 

 its head from side to side, thereby producing a crepitating 

 noise. 



The chrysalis is formed in a superficial cell on the 

 ground; its surface is black and roughened by confluent 

 punctures, but between the joints it is smooth and in- 

 clines to brown; the head-case is broad and rounded, and 

 the tongue-case is level with the breast; the tail termi- 

 nates in a rough flattened wedge-shaped j^oi^itj, which 

 gives out extremely small thorns from the end. 



The Moth (figure 141,) appears in the following 

 March or April, there being but one brood each year. It
