the infestation was generally low in Texas, Oklahoma, and Arkansas, but decidedly 
heavier than normal in Louisiana. It v:as more general than usual in Mississippi, 
though the intensity there was lower than usual, Eastward throughout Alabama 
and Georgia the infestation was generally low. As the season advanced further 
the insect developed no serious aspects except in Louisiana, Mississippi, and 
southern Alabama. Late in the season, however, considerable damage was done to 
the top crop, but the main crop as a whole was not seriously affected. 
The cotton flea hopper ( gsallus seriatus Reut.) occasioned very considerable 
excitement in July in Texas, Oklahoma, Louisiana, and Mississippi, extending 
eastward to Georgia, South Carolina, and North Carolina. The outbreak, however, 
was of short duration, and not so serious as anticipated except locally. 
The cotton boll worm ( Eel io this obsoleta Fab.) was somewhat more trouble- 
some than usual throughout the cotton belt, extending from Eorth Carolina to Texas. 
The year 1926 marks one of the unusual advances of the cotton leaf ^orm 
(Alabama argillacea Hon.) into the northern States, Late in May pupae and recently 
emerged adults were quite numerous in Wharton County, Tex. These continued to 
multiply during June in south-central Texas. Heavy flights took place from this 
center in the early part of July, and up to July 6, larvae were appearing in 
northern Mississippi, Louisiana, and Arkansas. From this new center a brood 
appeared about September 1 and swept northward, being recorded in Michigan on 
the 5th, in New York on the 7th, and Massachusetts on the 12th. The moths con- 
tinued to drift into the upper Mississippi Valley and eastern States in increasing 
numbers throughout the month. By the middle of September the larvae of this 
last brood were stripping the cotton in Georgia and South Carolina, In the Ohio 
River Valley in Indiana and Illinois the moths did considerable damage to peach, 
grape, apples ,and tomatoes. The insect was so numerous in parts of Mississippi 
that at one point where their march was impeded by a road the stench of their 
decaying bodies attracted turkey buzzards, and in certain cities and to'^ns in 
Pennsylvania and Massachusetts the enormous numbers of the moths caused con- 
siderable alarm among residents. The most unusual feature of this northern 
flight was recorded in October, when a brood of larvae from these moths was found 
on the experimental cotton plots at Arlington Farm, near Washington, D. C. , and 
on cotton plants at Monroe, Mich. Thisiinsect has never been recorded heretofore 
as producing larvae in the northern States.

GEEENH0US3 AND ORNAMENTAL PLANTS 
Among the insects affecting greenhouse nnd ornamental plants we may 
mention the finding of the sawfly Allan tus mellipes Norton at Moncton, New Bruns- 
wick; and the finding of the lilac leaf miner ( Graciloria syringella Fab. ) 
for the first time at Vancouver, British Columbia, 
The rose chafer ( Macrodactylus subspinosus Fab.) was generally below normal 
in population in New England and the Middle Atlantic States, the only report' of; 
its occurrence in serious numbers having been received from Nebraska. 
FOREST AND SHADS TEES INSECTS 
Among the forest and shade- tree insects the bagworm (T hyridoioteryx 
ephemeraeformis H aw.. was quite generally reported from the East-Central and
