I04 FIELD ZOOLOGY. 



With a pin or a toothpick turn one of the scales over 

 on to a glass slide and put it under the low power of the 

 microscope, in good light from above. Has the insect 

 any legs ? Can you find the sucking beak ? How was the 

 ■insect fastened to the leaf? Are the young insects 

 hatching from the eggs? If so, can you discover their 

 eyes and legs ? 



There are many hemipters which may well be claimed 

 for the insect cabinet. When such harmful hemipters are 

 taken from the killing bottle the pin should be thrust 

 through the thorax. A very valuable mount may be 

 made from some group or family of bugs, where big bugs, 

 little bugs, and middle-sized bugs are found feeding to- 

 gether. Pin them in a row, beginning with the smallest 

 of the lot, and increasing toward the last pin, which 

 should hold the adult insect, and may also bear the ticket.
