THE GRAPE LEAP-FOLDER. 3 
cords the species in limited numbers in Indiana. The latter writer 
recommends gathering and burning all dead leaves. 
Marlatt (17) gives a short account of the insect's life history and 
recommends the use of an arsenical spray as well as hand picking and 
clean culture as combative measures. 
Smith (19, p. 459) lists Desmia funeralis from several localities in 
New Jersey, and Bogue (18) records two broods of the insect in 
Oklahoma. Picking the folded leaves is recommended, together with 
rearing the parasites and allowing them to escape. 
Unusual injury by the pest in various localities in Georgia is 
recorded in the Annual Report of the Georgia Agricultural Experi- 
ment Station (20) . 
Webster and Newell (21), in Ohio, reared the insects, together with 
a parasite, Habrobracon gelechiae, from grape leaves. Washburn (23) 
records the insect in Minnesota and recommends hand picking. 
Pettit (24, p. 322) refers to its presence in Michigan. 
Quaintance (25) gives a short sketch of the life history of the grape 
leaf-folder, with treatment, the latter consisting of spraying, hand 
picking, and clean culture. Vines sprayed with arsenicals for other 
insects will not be troubled by the leaf-folder. 
Essig (26) has recently treated of the pest in California, giving a 
short account of the life history of the species; arsenical spraying is 
recommended as a remedy, although the insect has never become 
economically important in the Far West. 
DISTRIBUTION. 
Walker (7) gives the distribution of Desmia funeralis as United 
States and Nova Scotia to Orillia, Ontario Province, Canada. 
According to Marlatt (17) it occurs from New England southward to 
Florida, and westward at least to the Rocky Mountains. The Atlan- 
tic States is given as its range in Dyar's list (21). 
In California, according to Essig (26), it occurs in the central part 
of the State, being most commonly found in the Sacramento and San 
Joaquin valleys. 
It will be seen from the above and from the references given under 
the history of the species, that Desmia funeralis is widely distributed 
in the United States, covering doubtless all regions where the wild or 
cultivated grapes grow. It also extends on the north to include a 
considerable portion of Canada. However, the insect has not as yet, 
with occasional exceptions, assumed the proportions of a pest of much 
economic importance outside of the Central States between the lati- 
tudes of 35° and 40°.
