The Zebra Caterpillar (larva of Mamestm pidd) is a 



very easily distinguished in- 

 sect. When first hatched it is 

 almost l)lack hut soon becomes 

 pale and green. When full- 

 grown it is 2 inches long, 

 velvety black, with tawny red 

 head, legs and belly and two 

 narrow yellow lines along the 

 side between Avhich are many 

 white irregular zebra-like finer 

 lines. The pupa is found, like 

 that of the preceding species, 

 beneath the surface of the 

 ground. The front wings of 

 the adult moth are rich pur- 

 ple-brown and the hind wings 

 are white, faintly edged with 

 brown, (Fig. 12). 

 The Cabbage Evergestis or Cabbage Pionea as it used to 

 be called {Evergestis rintosalis) is a small purplish-brown or bluish- 

 brown worm with a greenish-yellow head and green venter. When full- 

 grown it is a little over half an inch in length and 

 transforms to pupa at the surface of the ground in 

 a slight oval cocoon covered with earth. The moth 

 is pale ochre-yellow in color, the front wings dark- 

 ening towards the tip, with the hind wings semi- 

 transparent near base, (Fig. 13, c). It has a wing

if it confined itself to the outside leaves. 



The Cabbage Plutella 

 { Flute lla cruciferaruiii) is a 

 little, active pale green worm, 

 something over a quarter of 

 an inch in length. It pupates 

 within a delicate gauze-like 

 cocoon resembling lace. The 

 parent moth has narrow wings 

 — expanding five-eighths of 

 an inch, and is of an ash- 

 gray color, usually with an 

 undulate pale streak along
