INSECTS ATTACKING CLOVER SEED. 880 



hairy, and when full grown the caterpillar is 3.5 c m, or one inch, 

 long. The chrysalis, like that of our cabbage butterfly, Pieris 

 rapa?, which it resembles, is suspended by an anal tuft and a shoul- 

 der girdle. It is pale green, tinted with yellow. On each side of 

 the head is a dark red line, and yellow stripes are seen on the 

 sides near the tip. The yellow, occasionally very nearly white, 

 butterflies with wings bordered with black, sometimes gray, black, 

 or brown are well shown in the figure. The liorder "s narrower 

 in the male, and encloses yellow spots in the female. A black 

 spot is seen on the front wings of both sexes. The secoiulary wings 

 are bordered with dark in both sexes, and bear an orange spot. 

 The antennae and fringe to the wings are pink. The body is 

 black above and paler below. The size is given in the figure. 



The eggs are laid in ^lay and August on the clover, and other 

 leguminous plants, as peas, etc. The caterpillars are feeding 

 from four to six weeks. The chrysalids are fastened to clover or 

 other object, and last about twelve days. The butterflies swarm 

 in ^lay and agidn in July and August, when they are often so 

 thick as to remind us of a snow storm. 



What was said of danuiges and I'emedies in considering the 

 last insect applies as well to this one. 



Insects Attacking CIoTer Seed. — While the damage done to 

 clover by some of the insects already described, especially the 

 borers, is quite serious at times, the danger from those attacking 

 the seed is still more formidable, and may well cause anxiety. 

 Happily the number in this list is very limited.
