above ground, but are completely hollowed out. It is something entirely 
new, but the attack is very severe in this section. Whole fields of beans, 
in many places containing many acres, are completely ruined. and are 
being plowed up. 
Can you tell us what it is, and whether there is any remedy ? 
Also, is there any remedy for cut-worms, other than hunting down each 
specimen ? Respectfally,

Pror. Orro LuGGER, State Experiment Farm. Dear Sir:—Some 
beans were planted on my farm one-half mile west of Wadena on ground 
that had been newly plowed and had previously been coated with barn- 
yard manure. The seed was old, and some of it had been picked after 
the frost came. After about ten days, seeing that they did not come up, 
I dug into the hills and found that the beans were gone. After cpening 
several hills I succeeded in finding the specimens enclosed. Is the worm 
a product of the soil, or did it develop in the bean? If the former, what 
means can be used to destroy it ? Respectfully, 
Wadena, Minon., June 24, 1895. H. W. FULLER. 
It seems that about one-third of the state was more or less 
infested with this new enemy, but chiefly the more northern 
counties. Here it did great damage, in some cases destroying 
nearly all the bean-plants, while in others farmers were forced 
to re-seed their fields. The work of the insect is shown in Fig. . 
58, Plate 14. It will be noticed that not only the seed is hol- 
lowed out, but the stem as well, thus invariably killing the 
plant. 'The worms that cause this damage are footless mag- 
ots, measuring about a quarter of an inch ora little more; they 
are of a yellowish-white color, tapering in front and blunt be- 
hind, as shown in the illustration. After feeding some time 
inside the bean or bean-stalk they reach their full size, and 
leaving the old home they penetrate into the surrounding 
earth, where they contract into peculiar barrel-shaped, smooth, 
light yellowish-brown puparia or false pupz. Inside these 
puparia, which are nothing but the shrunken old skins, the 
true pupze are formed. In about a week after having changed 
to a puparium, the adult insect pushes open a little cap at the 
front end of the puparium, and works its way to the surface. 
The adult insect is a small fiy illustrated in Fig. 58, Plate 14, 
both enlarged and natural size. It resembles a small house- 
fly, and lacks all conspicuous markings. Soon after appearing 
as flies those kept in captivity with young and growing beans 
deposited a few elongated, white and glistening eggs, which,
