APPENDIX. 191 



various species of the genus Ceuthophilus and allied 

 genera, called Cave-Crickets, are found under stones, 

 logs, in cellars, and in caves. 



Acrydii, Locusts, are found in the grass, on barren 

 rocks and hills, on sandy beaches, on marshes, in 

 meadows, and often in the pine woods, especially in 

 the South. They are best taken with the net. As 

 many of the species have colored wings, the rarer ones 

 are quite easily detected. They are often exceedingly 

 local in their distribution, and members of certain 

 species may be found, year after year, in the same lo- 

 cality. 



Phasmida, Walking-Sticks, maybe found on bushes, 

 generally in rocky pastures. Some of the species are 

 found in Florida quite abundantly, on the trunks of 

 trees, or on the grass in the pine-barrens. 



Mantid^e, Walking-Leaves, are found on leaves of 

 plants and shrubs. 



Blattari^;, Cockroaches, are found in houses, ships, 

 etc. ; but some species are found under bark and stones. 



Forficularl^i, Earwigs. — I have found these in- 

 sects in great numbers, beneath stones, in southern 

 Florida. Large flights occasionally occur at night, in 

 the north, and as they are attracted by light, they are 

 easily taken. 



I do not now recommend placing even the larvae of 

 Oithoptera in glycerine, as it will not preserve the 

 color for any length of time. 



Lepidoptera, Moths and Butterflies. — Especial care 

 should be taken to collect the larva? of the various 

 species ; notes should also be taken as to the food- 

 plants of the larvsB. Mr. Scudder recommends opening 

 the larger species of larvae behind, ami removing the 

 contents of the skin by compression. Then the skin 

 is inflated by means of a straw, and while in this con-
