NATURE-STUDY LESSONS. 71 



29. Observe closely to see whether the chrysalis 

 changes its form. 



30. Make records with a view to discover how many 

 days the insect remains in the pupal condition. 



31. Examine the empty case. 



32. Describe the butterfly immediately after its emer- 

 gence from the chrysalis stage. 



33. What are the different stages through which it 

 has passed ? 



34. Draw the butterfly in different positions. 



35. (a) Into how many parts is the body of this new 



form divided ? 

 (6) How many wings has it ? 



(c) How many legs has it ? 

 (d?) How many antennae ? 

 (e) How many eyes? 



36. After study of the butterfly show why it is a true 

 insect, and compare it with some other kind of insect, as 

 the be« or grasshopper or potato-beetle. 



D. The Butterfly and its Parts. 



Try to obtain a few specimens ; kill them by placing them in a poisoning- 

 j,ir. Such jars are made by placing in them cotton-batting saturated with 

 chloroform or carbon bisulphide, or putting in one or more lumps of cyanide 

 of potassium. The last-mentioned poison is frequently embedded in pl.isler 

 of Paris in the bottom of the jar. Pin them on cork in order to be able to 

 make closer observations. Also collect specimens for the breeding-cage. 

 While the eggs are developing, study the butterfly as a whole. 



37. (a) Observe the butterfly among the flowers. 



(d) What were the butterflies doing among the 



flowers ? 

 (c) Make a list of plants upon which you have 



seen these white butterflies resting. 

 {d) What part of the flower does it use for food?
