BUTTERFLY. 



Notice the relative size of the wings. How are they carried 

 when the insect is at rest? Rub the wings and notice your 

 fingers. Scrape a wing with a scalpel and study the ' dust ' 

 under the microscope. With what is the body covered? Sketch 

 the veins in the wings. 



Study the head. Below, notice the proboscis. Straighten 

 it out with a needle. At the sides of the base of the proboscis 

 see the labial palpi. Are the antenna? of the same size through- 

 out their length Sketch the head in outline, then remove 

 the hairs, etc., which cover it and look for eyes and ocelli, 

 inserting what you find in the drawing. 



Do you find in the legs the same joints as in the legs of grass- 

 hoppers? Have the tarsi of all the legs the same number of 

 joints? Is the base of the abdomen as broad as the thorax? 

 Do you find cerci or ovipositor?
