the seed com in water over night and then mixing the corn with a large 

 quantity of Paris green, so as to cover each kernel just before planting, 

 and thereby kill the insect while trying to eat its way into the kernel. 

 This method, however, has never been tested on a large scale. 



The adult insect can be determined by the 

 ordinary corn grower from its general shape, 

 which one will recognize by the figure, and also 

 by the fact that the insect is about one-fifth of 

 an inch in length, and just a Httle over one-third 

 of an inch across its expanded wings. The front

 antennae, palpi and proboscis are black. The area occupied by the ocelli 

 is heart-shaped. The abdomen and the thorax are light yellow, with 

 brown colored sinereous spots, more or less covered with minute black 

 points at the intersection of the bristles. The back of the thorax has a 

 distinct dark brown stripe down the middle, as can be seen in the illustra- 

 tion. The legs are black. The puparium, inside of which the true 



pupa is found, measures a little less than one- 

 fifth of an inch in lengih and is of an oblong 

 shape, similar to the figure of a pupa above in- 

 dicated. It is of a reddish-brown color, narrowly 

 rounded at each end. The posterior tubercles are 

 all present, although shrunken and surrounding 

 the posterior stigmata. The larva is about one- 

 fourth of an inch in length, and is quite thick at 

 the widest part, which is near the posterior ex- 

 tremity. The posterior half of the body is cylin- 

 drical, and from this point to the anterior portion, 

 becomes tapering with increasing rapidity to the

The well-known wireworms are the larvae of beetles that are popu- 

 larly known under the names of Click-beetles, Snap-beetles, or Snapping- 

 jacks. These beetles are well known to every country lad, and more or 

 less even to the town boys, because of the peculiar habit these beetles 

 have of bending their bodies when held in the fingers and suddenly
