BUGS, OR HEMIPTERA. 121 



found in other situations live under material cast up by the ocean ; 

 others are found along the shores of lakes and rivers, and many 

 also are found living in the water. 



Beetles can easily be captured by the use of large forceps ; they 

 should at once l)e thrown into the Cyanide Bottle, whert they will 

 die instantly. 



To mount the large specimens, force the pin through the right 

 wing-cover near the thorax ; before placing it in the cabinet ar- 

 range the legs in their natural position and paint the abdomen 

 and thorax with a solution of corrosive sublimate and alcohol. 

 This will keep away those destructive pests, Anthfenus and Dermes- 

 tes. The solution can be made by taking one ounce of corrosive 

 sublimate to half a pint of alcohol. Small beetles can be gummed 

 on card-board as before mentioned, and then arranged in the 

 cabinet. Beetles may be preserved in alcohol or in a weak solu. 

 tion of carbolic acid. The latter has additional advantage of pre- 

 serving the specimens that have been immersed in it from the rav- 

 ages of noxious insects for some time. Glycerine is excellent for 

 preserving beetles that have delicate colors which fade in alcohol, 

 but they cannot be mounted without being cleansed. 



While traveling, Coleoptera, with their larv?e, etc., should be 

 thrown into bottles and vials filled with strong alcohol. When the 

 bottle is filled, new liquor should be poured in and the old may be 

 saved for collecting purposes ; in this way the specimens will not 

 soften and can be preserved indefinitely, and the colors do not in 

 most cases change. 



Hemiptera: Bugs and Plant Lice, can be found in large numbers 

 on low bushes and in the grass during the summer and autumn. 

 The large carnivorous kinds are often found on bushes with cater- 

 pillars transfixed in their jaws. Hibernating species are found 

 under leaves in hard-wood forests. 



The numerous aquatic species should be taken out of the water 

 with a net, and should be carefully handled to avoid the sharp 

 sting or piercer, with which some are armed. 



The soft-bodied species of Aphis or plant lice, may be preserv- 

 ed in alcohol or glycerine. All the bugs should be pinned through
