ordinary sweeping methods. A total of 959 adults have "been examined 
showing 55 percent of the total number collected were females. The 
tachinid parasite Gymn oso ma f uliginosa Desv. is present in reason- 
ably small numbers. 
MITES (Acarina) 
Texas. F. L. Thomas (March 21): An unknown mite, larger than the red 
spider, caused local damage to oats in Hood, Bosque, and Denton 
Counties the latter part of January and in February. Investigations 
showed that the infestation occurred only on land where oats had 
been planted continuously for several years. 
CORN 
CORN EAR WORM ( Heliothis obsoleta F. ) 
New York. L. A. Carruth (March 22): Conditions on Long Island seem 
favorable for the survival of the corn ear worm pupae. The natural 
mortality of the pupae during the winter months is probably between 
95 an^L 99 percent, but the survival of even a fey' individuals is 
sufficient to insure serious infestations during the following 
season. During the spring of 1937 live pupae were found on Long 
Island and reared to adults. From present indications, this situ- 
ation will apparently be repeated during the spring of 1938- 
Texas.' F. L. Thomas (March 21): Eggs have been found in alfalfa in 
Falls County, central Texas, although no emergence Of adults has 
yet occurred in Brazos County. Very strong evidence has been ob- 
tained this year indicating that the moths spread rapidly over 
considerable distances. 
Utah. H. E. Dorst (March lU) : A recovery of approximately 65 percent 
of the pupae has been obtained this spring from overwintering cages 
that successfully transferred from larvae last fall. A recovery of 
approximately 50 percent of the pupae were obtained in unplowed corn- 
fields. 
SOUTHWESTERN CORN BORER ( Diatraea grandiosella Dyar) 
Texas. F. L. Thomas (March 21)': This insect was found to have extended 
its range east to Wilbarger County and southeast to Taylor County, 
according to the survey last fall. It has been distributed through- 
out the Panhandle for several years. 
. ALFALFA 
ALFALFA WEEVIL ( Hypera postica Gyll. ) 
Utah. G. F. Knowlton (March lU) : An adult weevil was observed to be 
active in an alfalfa field at Riverside, in northern "Utah.
