Carabidae. The Ground Beetles 

 They are to be looked for on the ground where they hide 

 under stones and other cover. Some prefer the edges of 

 ponds; others, dry places, while still others are found in 

 sphagnum moss or wet moss in deep woods. Some of our 

 species fly freely on warm spring mornings, particularly near 

 wet places. The way to take the bog species is to stamp 

 around on the surface of the bog and drown them out. I have 

 found by working potato patches and turning over the stones, 

 a week or two after the crop has been harvested, a most fruit- 

 ful field. The molasses trap is very successful.
