and L902 this maritime form destroyed the timothy in the vicinity of 
Reidsville, N. C. This is on the southern border of timothy culture 
along tin 1 Atlantic coast, and some years ago an attempt was made to 
grow timothy In thai seel ion. The grass did ?ery well until the above 
mentioned attack occurred, and by L905 there was but little remain- 
ing." Strangely, too, uowhere along the Atlantic coast do we find the 
short-winged individuals far inland until we reach New York and the 
New England States, and what is equally perplexing they do not there 
attack grain, but grass, whereas to the southward, except near the sea- 
coast, it is the grain fields that are devastated by the long-winged 
form. In other word-, throughout New England, New York, north- 
eastern Ohio, northern Indiana, and the Dominion of ( 'ana da we have 
both the lone- and short winged individuals occurring together, but

In Bulletin IT. old series, Division of Entomology, U. S. Depart- 
ment of Agriculture, Dr. L. (). Howard, the author, stated thai in 
L88G a timothy meadow located near Wakeman, Huron County, Ohio, 
was considerably injured by chinch bugs. Since that time the species 
ha- never been reported from that section of the State, and the writer 
ha- found that depredations of that particular character are only 
committed by the more or less brachypterous race. This ha- been 
supposed to be largely confined to the northeastern portion of the 
State, though there seems to he no good reason why it should not 
appear in northwestern Ohio also. Owing to these facts tin- -ingle 
occurrence in meadows, recorded by Doctor Howard, formerly puz- 
zled the writer greatly. 
During the fall of 1898 there came reports of very serious destruc- 
tion of meadow- in Huron and Lorain counties, which lie contiguous 
to each other, the cau-e being attributed to the dry, hot weather. But 
an examination of the meteorological records for that section revealed 
the fact that there had been no weather condition sufficiently severe 
to affect timothy meadows in that way. A survey of the affected 
meadow- during early spring of 180;) revealed the presence of great 
number- of brachypterous chinch bug- hibernating in these meadow-, 
and the problem was solved. The species had doubtless been doing 
more or less injury since 1886, entirely unknown to the farmer or any- 
one el-e. thus -bowing the extent to which it- secluded life in 
meadow- protect- it from observation. This section of the State 
since 1886 has been more largely devoted to dairying, and the 
meadows are not a- rapidly rotated with other crop- as when the 
cereal- were grown more extensively.
