• ThijSi.naetfs tb^jvLJ' k J.2'?.:tl\s contention that in all probability the 
great outbreaks of Toxoptera have not teen due to early migra- 
tion, bur to the development of the insect in volunteer grain 
throughout the regions most seriously infested, and the apparent 
progress of the insect northward is due more to the progress 
of spring than to migrations of the adult Toxoptera. The present 
evidence, of course, is not conclusive but is enlightening v/ith 
respect to this matter." 
Kansas J. R. Horton, Bureau of Entomology (March 16). "March examina- 
tion shows the following status of the green bug in several 
counties in Kansas; Examinations were made in Sedgwick, Sum- 
ner, Harvey, McPherscn, S n line, Dickerson, and Marion Counties, 
and no green bv.g was found with the exception of two nymphs 
which were found in a field two miles south of Bell Pl-dne in 
Sumner County* ''/heat is generally in good condition due to 
recent rains. During r^oa t of the winter it has been poor ow- 
ing to severe drought, and practically no volunteer 2nd little 
of the seed grain sprouted until February - conditions which 
are rather unfavorable for aphids." 
M eromyza punct.lfer Becker 
Oregon L. P. Rockwood, Bureau of Entomology (March 8 ). "I have just 
received the Meromyza material reared from wheat collections 
during the outbreak in Union County, Oregon, in June and 
July, 1921, determined by Dr. J. M. Aldrich, who found but one 
Meromyza ameriloan a Pitch in this lot, all the other specimens 
being M, punctifer . It would be advisable, therefore, to 
change the records published in the last volume of the Survey 
Bulletin on this outbreak so as to refer to M. punctifer as 
the species causing the damage. However, I think it would 
be advisable to retain the record of the occurrence of M. 
araer ic a na in this region, as it has been stated that this 
species dees not occur west of the Rocky Mountains." 
"HEAT MIDGE ( Contarinia tritici Kirby) 
"ashington L. P. Rockwood, Bureau of Entomology (March 8). "The wheat 
midge, records c? which were published in the Insect Fest 
Survey -Bulletin, Volume 1, No. 4, page 147, and Volume 1, No. 
5, page 180, should be corrected. Dr. E. P. Felt has de- 
termined the material from this infestation as Thecodiplosis 
mo g el Ian a Gehin. Similar material was reared from wheat 
collected at Batavia, N.Y. in 1912, by Dr. Felt."

Kew York C. R. Crosby (March 22). "/. very complete survey was carried 
on during the late summer of 1921 to ascertain the infestation 
of wheat by tiie jointworm in the more important grain-graving 
counties of New York State, These examinations wore made 
co-operatively by this .office and the Bureau of Entomology,
