 grown. Its body is considerably flattened and of a light waxy-yellow 

 color. Figures 28 and 29 well illustrate its characteristic features. 



(It is described in detail in Bulletin 33, p. 268). 

 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- 

 termine whether they emerged in the fall or passed 

 the winter in the earthen cells. Professor Forbes 

 has recorded considerable 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 ; 

 and that it lives two sea-

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