40 N. S. ENTOMOLOGICAL SOCIETY 



Second Instar. Resembles the previous instar in every re- 

 spect except size and color. Immediately after moulting it is 

 a very dark brown, almost black, but after a couple of days it 

 begins to turn to a light, reddish color as before. 



Length of body, 2.97 m. m.-3.12 m. m. Greatest width .945 

 m. m.-.998 m. m. Width of prothoracic segment .75 m. m.- 

 • 81m. m. Width of head .54 m. m.-.62 m. m. 



Third Instar. With the exception of size, this stage re- 

 sembles the preceding one. The tubercles are considerably 

 larger in proportion to the size of the body. 



Color. Same as second instar, but the apex of each tuber- 

 cle is much lighter than the base. 



Length of body, 4.45 m. m.-4.50 m. m. Greatest width 1.75 

 m. m.-1.89 m. m. Width of prothoracic segment 1.48 m. m. 

 1.62 m. m. Width of head 1.16 m. m.-1.21 m. m. 



Full grown larva. During the third instar the larva grows 

 faster than in any other stage, but the tubercles, which, directly 

 after the second moult were comparatively large, do not in- 

 crease in size in proportion to the body. Head, very small. 



Color, light, reddish brown, darkest at the segmental mar- 

 gins and lightest round the tubercles. Between the double 

 row of tubercles that runs longitudinally over the dorsum,there 

 is a faint, dark brown line. Spiracles, dark brown. 



Length of body, 9.72 m. m.-10.26 m. m. Greatest width 

 2.56 m. m.-2.70 m. m. Width of prothoracic segment 2.02 m. 

 m.-2.16 m. m. Width of head 1.21 m. m.-1.35 m. m. 



The Pupa. 



Upon attaining full growth, the larva ceases feeding for 

 several days and is very restless. It eventually enters the loose 

 soil or decaying vegetable matter and spins an earthen cocoon 

 in which it transforms to a pupa. 



Description. The general characteristics of the future 

 adult can be distinctly seen, while the tubercles and spines 

 that the insect had in the larval stage are still visible, the cir- 

 clet of spines posterior of the head being very prominent. 



Antennae, lying closely round thorax, reaching to the base 

 of the rudimentary wings. Legs, only the second and third 

 pair visible, the first pair being folded closely under the others. 

 Rudimentary wings, translucent, reaching to the middle of the 

 fifth abdominal segment. 



Color, salmon, the appendages being lighter. 



Length, 5.21 m. m.-7.56 m. m. Width 3.10 m. m.-3.40 m.m
