broken stems in some wheat fields. Our annual wheat- insect survey will 
start in southern Ohio this week. 
Indiana. J. J. Davis (June 25): An unprecedented outbreak of the spring 
brood of the hessian fly has covered the State of Indiana, and is 
probably most severe in the central part of the State. In some local- 
ities wheat has been killed outright, as in Boone County, where perhaps 
one-third of the wheat -fields have been destroyed. Many other fields 
are beginning to show damage from lodging. The heavy spring infesta- 
tion is owing in a few instances to early sown wheat, but in general 
to the large amount of volunteer wheat that developed in waste land and 
elsewhere last fall. 
Illinois. W. P. Flint (June 21 ): The spring brood of the hessian fly has 
been unusually heavy, resulting in from light to moderate damage in 
the wheat areas of the State. 
Missouri. L. Hasoman (June 26): There has been a rather definite pick-- 
up in the abundance of hessian fly. It is attributed to the favorable 
weather of the past fall and to the large acreage of liieat seeded early 
for pasture. The pest is more abundant in the southern half of the St at . 
Kansas. H. R. Bryson (June 27): Observations made in' southeastern Kansas 
by R. E. Painter indicate that the hessian fly is very abundant in the 
vicinity of Parsons. 
3LACK GHAUT-STEM SAOTLY (Trachelus tabidus Fab.) 
Pennsylvania. E. J. Udine (June 13): Adults have been flying in abundance 
the last few days throughout most of western and south-central Pennsyl- 
vania. Adults are still flying in abundance in fields near Red Lion, 
in York County, but are becoming scarce in western Franklin County where 
larvae are already in the first instar. 
Virginia. J. S.Pinckney (June 20 ): Hibernating larvae of the black grain- 
stem sawfly were found in wheat stubble in Campbell County. About 
2-percent infestation was noted in the fields examined. 
Ohio. J. S. Houser (June S): On June 4 adults were abundant in wheat and 
rye in Mahoning County. Oviposition in wheat was observed near iTorth 
Lima on June 8. Eighty- seven adults were captured in a field of wheat 
near Ellsworth by making one hundred sweeps of a sweep net 15 inches 
in diameter. Losses in this area will probably be heavy this year. 
A WHEAT-STEM SAWFLY (Cephus pygaaeus L. ) 
Pennsylvania. C. C. Hill and E, J. Udine (June 12-13): Adults are flying 
abundantly in wheat fields near Williamsport , in Lycoming County, and 
at Red Hon, in York County.
