however, were not fertilized. This at least was the conclusion 
arrived at, as no maggots appeared in the beans or stalks of 
beans growing in the breeding-cage. Nor could any worms be 
found later in fields seeded a second time with beans, which 
seems to indicate that the other generations produced by these 
insects during the summer possess different habits than the 
first generation. This is also borne out by many other obser- 
vations. 
The flies belong to the genus of Anthomyia, a genus of flies - 
in which the larve have very different habits, although the 
adults resemble each other very closely. Some of these larvee 
live inside the soft kernels of seed-corn; others attack onions, 
radishes and stems of cabbages; others again breed in decay- 
ing vegetable matter and dung; some produce mines in various 
leaves, and still others become our friends by eating the eggs 
of grasshoppers. The flies resembling each other so closely 
it was thought best not to add another name, very likely a 
synonym, to the already long list of such worthless names. 
It is possible that owing to the unusual wet season at the 
time that these beans sprouted and grew, these flies left their 
- usual food, decaying matter, and attacked the richer one planted 
for them. Flies of this kind are always numerous in Minne- 
sota, and they frequently swarm in very large numbers. 
Remedies. 
It would be very pleasant to give some real good remedies 
against this insect, which may appear again, though 
very likely this will not be the case for a number of seasons. 
Asa general rule the mischief is all done before the culprit is 
discovered, and a remedy under such conditions is out of the 
question: Toward theclose of June no more damage was caused 
by these maggots. The following letter, one of many received, 
indicates this very well: 
ProF. Orro LuGaG@ER. Dear Sir:—Since sending you the sample of 
infested beans have lost 25 per cent of the crop, but now can not find 
many stalks, so shall replant at once. ———— Since writing you 
before have heard of a neighbor that lost his crop in the same way; have 
also examined several fields but can not find any maggots. 
Yours respectfully, 
Alexandria, June 29, 1895. J. W. ROBARDS.
