Mississippi. C. Lyle (July 23): Collected from pine on July lU. 
SPRUCE BUDW0RL1 (Cacoecia fumiferana Clen. ) 
Michigan. E. I. McDaniel (July 19): An extensive area of jack pines has 
"been defoliated in the vicinity of Negaunee. This area covers several 
thousand acres. 
Minnesota.- A. G. Ruggles (July 19): Spruce "budworn is noderately ahundant. 
Colorado, J. A. Beal (June): A heavy infestation is occurring on ponderosa 
pine hear Sugarloaf . An examination of the infested area showed the 
larvae to "be very ahundant over at least a section of forested land. 
On June 25 the larvae were tiny hut had spun wehs on nearly all the 
pine "buds in the area examined. In some instances two or three larvae 
occupy a single hud. They are feeding on the needles and "boring into 
then at the "bases. This "budworn prohahly represents a different strain 
than the one. found infesting Douglas fir on other parts of the Roosevelt 
Forest. No sizahle areas of infestation have previously occurred in 
pure stands of ponderosa pine. The present one threatens to "become 
serious. 
RED-HEADED PINE SAWELY ( Neodiprion lecontei Eitch) 
Michigan. J. K. Kroeher (July 2k) : Sawfly larvae on jack and red pines now 
more numerous than ever noticed "before. About half grown. Will 
prohahly result in killing one or more plantations on the Mackinac 
State Eorest. 
A SCARA3ID ( Pachystethus ohlivia Horn) ' 
Michigan. L. E. Yeager (June): An outhreak of the pine chafer "beetle, which 
has caused considerahle alarm "by its defoliation of jack pine on the 
Manistee National Eorest in Michigan, is much less severe this year. 
This outhreak has "been in progress since 193^" rind, so far as known, 
this is the first period when the insect has occurred in destructive 
numhers. The heetles eat into the sides of the needles near the "base, 
cut off some needles, and cause others to die. This gives the affected 
trees the appearance of having "been scorched. Only the needles on the 
current season's growth are eaten hut, after 2 or 3 years of attack, the 
trees "begin to die in the tops, causing stag-head. Feeding tests with 
larvae do not indicate that the larvae feed to any extent on the roots 
of trees. 
WHITE-PINE WEEVIL (Pisspdes strohi Peck) 
New England and New York. E. P. Eelt (July 23): Has "been somewhat in- 
jurious to leaders of white pine and also in spruce tips in southern
