 Figures 28 and 29 well illustrate its characteristic features.

 They undergo their transformations in earthen cells 

 in the soil, the change to a beetle taking place about 

 July 1st. The beetle is of a general rusty-brown 

 color with black markings ; it is shown natural size 

 and enlarged in figure 30, We were unable to de- 

 ,^^J^^ termine whether they emerged in the fall or passed 

 '^l^ the winter in the earthen cells. Professor Forbes 

 has recorded consideral>le data on this point which 

 leads him to conclude that it seems probable that 

 they emerge in the sum- 

 mer and early fall, proba- 

 bly laying their eggs in 

 part the same season; that 

 it hibernates in sheltered 

 places and continues 

 abundant until June of 

 the following year, doubt- 

 less breeding meanwhile ;

We met with a few wireworms of this species in old sod land. 

 The beetle has been known since 1823, and it is not uncommon 

 throughout North America. It is a robust beetle, about one-fourth
