ELM 
A POCKET GALL ( Eriophyes ulmi Gam. ) 
M. H. Swenk (May 15- June 15): Heavy infestations of elm 
leaves with the elm pocket gall, Erio-phy es ulmi were re- 
ceived from 3uffalo County during the last half of May. 
ELM COCKSCOMB GALL (Colopha ulmi cola Fitch) 
H. L. Bailey (June 23): A very heavy infestation of the 
cockscomb elm gall is reported from Hi chord. More than the 
usual numbers noted elsewhere. 
ELM 'LEAF MINER ( Kaliofenusa ulmi Sund.) 
W. E. Blauvelt (June): Specimens of infested elm leaves 
were received from Warsaw, May 29, Parish on June 3, from 
East Aurora, June 8, and from Sodus on June 10. 
MOURNING-CLOAK BUTTERFLY ( Aglai s antiopa L.) 
E. W. Mendenhall (June 18): The spiny elm caterpillar is 
quite bad on the elm stock in the nurseries in Lake County. 
J. J. Davis (June 24): The spring elm caterpillar par- 
tially defoliated elms at Columbia City and Lafayette June 
13. It was also common on willow at Rensselaer June 12. 
ELM FLEA BEETLE (Haltica ulmi woods) 
A. E. Stene (June 24): I found the elm flea beetle in Nar- 
ragansett Pier in one place and also found a few beetles near 
Kingston, althaugh they did not seem to be anywhere as nearly 
abundant there. Previously I have found them about 5 miles 
west of Narrag^nsett Pier m what is the southern part of 
South Kingstown. They have also been reported from the south- 
ern part of the city of Cranston. They may have been present 
in other parts of the State but we have not had a chance to 
check up on it carefully enough to make definite records. 
ELM LEAF BEETLE ( Galerucella xanthomelaena Schrank) 
E. P. Felt (June 23): Eggs and small grubs occur in south- 
ern New England. The insect is somewhat later than usual. 
The trees have developed a very abundant foliage, and this 
may result in reduced injury as compared with last year. 
Providence Journal (June 9): This insect pest is known as 
the most important leaf-eating enemy of the elm, and it is 
prevalent in Rhode Island in great numbers this year because 
the long drought of 1930 enabled it to survive the winter 
cold more easily than usual.
