of May, some of them pupating, however, as early as the bth 
April. Finally, the imagos from these pupae appear in May and 
June. 
TV e are, unfortunately, unable to say as yet whether this insect 
is dependent on an opportunity to breed in volunteer grain, whether 
it may breed in other grass-like plants, or whether it may, on oc¬ 
casion, suppress its midsummer brood and content itself tempora¬ 
rily with two generations a year. 
The fact that the bulb worm occurs in volunteer wheat con¬ 
temporaneously with the fly and in the corresponding stages, 
makes available for the control of this insect the measures recom¬ 
mended against its better-known companion. To recapitulate these 
briefly, if stubble ground be so managed as to promote a growdh of 
volunteer grain at such an interval before seeding that the final 
preparation of the soil will destroy the young growth while the 
bulb worms infesting it are still too young to complete their trans¬ 
formation, this must necessarily check the multiplication of 
the pest, if it does not completely arrest it. There is", however, 
a possibility that this insect will be found to breed in volunteer 
oats, as well as in the wdnter grains, in w-hich case the method 
outlined above will probably be of less effect than for the Hessian 
fly- 
One interesting feature in the natural history of this species ; 
still remains undetermined. At present no mode of hibernation of 
the Meromyza is known except that in the larva stage in winter wheat 
or rye; but the imago has been decidedly abundant in summer in 
regions where winter grain is raised in* very small quantity, and 
where, nevertheless, it did not suffer noticeably from insect injuries. 
TV e have here, consequently, grounds for the suggestion that 
this species .may develop in other plants than the various grains 
which alone it has hitherto been knowm to attack.
