with black. Beyond the stigmata is the hghtest part of the 

 wings, with a double row of dots, one or two sagittate marks, 

 and an indistinct zig-zag sub-marginal line. The hind-margins 

 and fringes are dark brown. I'he hind-wings are dusky grey, 

 with light grey fringes, and the lunule of the under side 

 showing through. 



The larva is very handsome, and has suggested the name 

 of the genus, Calocampa, which is derived from the Greek 

 KoKw, beautiful, and Ka/^inr], a worm. Stainton's opinion of 

 the larva is as follows : — "Any one who has not yet seen the 

 larva of C. exoleta has a treat in store. I have only once seen 

 it, and then I nearly screamed with delight. No figure can 

 give any idea of the beauty of the living larva." It is bright 

 green, with a pair of white spots on each side of the back, 

 each pair being connected by a black blotch. Below them is 

 a yellow stripe. This is succeeded by a space on which stands 

 a row of three white dots on each segment, ringed with black ; 

 and on most of the segments there is a fourth dot above the 

 middle one. Just over the legs there is a red stripe, bordered 

 with white. It feeds on a variety of plants, but prefers 

 lettuce, spinach, and asparagus. The larvae are very difficult 

 to rear, being liable to the attacks of ichneumons, and if the 

 pupae are not kept at exactly the proper degree of moisture, 

 the specimens are crippled. The larva is slow and sluggish 

 in its movements, and if touched, it contracts itself and emits a 

 green liquid. 



The pupa is shining reddish brown, and so delicate that the 

 outlines of the moth are visible through it. It remains in this 

 state for about four weeks, the moth appearing on the wing in 

 September and October.
