Micftigan. E. I. McDaniel (September 2^): This insect has been particularly 
destructive for the last U or 5 years, and there are very few sound 
hickory trees left in the State. The atta.ck has "been aggravated by the 
prolonged drought, which has weakened the trees so that they are very 
susceptible to attack. The most recent outbreak occurred just out of 
Detroit. Here a number of large hickories in a stand of hardwoods were 
attacked and practically every tree has died within the last few weeks.

BED-HUMPED OAK WORM ( Symmarista albifrnns A. and S. ) 
Michigan. E. I. McDaniel (September 2^): The red-humped oak worn has been 
sent in from Grayling, and also from the vicinity of Traverse City. In

covers the area between Grayling- and Traverse City. Both red and white 
oak are attacked.

nut borer is extremely abundant in oaks on Long Island, particularly 
in the vicinity of Manhasset, whore many trees arc dead or dying, 
probably due primarily to a series of dry summers and to defoliations 
by canker worm's. The work of this insect was also rorortcd from Upper 
Montclair, P.J.
