The males are distinguished by an elevated black spot on one Df the veins, near the middle of the hind wings. Where is this butterfly found most abundantly? Development of the Cabbage Butterfly. The cabbage butterfly is small, yellowish beneath, paler above with black tips to the anterior wings. The male has one round black spot only on each upper wing, while the female has two, and sometimes three. I. Open the abdomen and look for eggs. They are yellow, oval bodies, ribbed lengthwise, with cross markings on the ridges resembling stunted ears of yellow corn. Look also for these eggs on cabbage leaves, or where the butterflies are seen hovering. Watch the butterflies closely as they light on the cabbage leaves to see the egg deposited on the leaf; on which side of the leaf are the eggs usually laid? How are they fastened to the leaf? Make a drawing of the egg as found attached to the leaf. 2. Get a chalk box with a sliding cover; substitute a glass cover a httle longer than the box. Keep the box on end, so that the door will keep closed, yet may be easily opened. Put into this box a cabbage leaf with eggs on it; examine several times a day. What becomes of the egg? In another box, similarly arranged put some large cabbage worms; give them fresh leaves every day, and keep the box in a light, well-ventilated room. Watch closely, and keep record of the date of the beginning of the experiment, and note the date of any change; describe carefully all actions and changes in the worms. Make careful drawings of each stage of growth ; — (a) The egg. (^) The larva, at different stages of growth; keep one worm in a cage by itself, and make a drawing every third day.
