Orcg. Agr. Coll., Insect Pest Report (May): T. R. Charaber- 
lin reports that approximately 5 per cent of the wheat joinfe 
"Om. were out of the stubble "oy May 5 in the Molalla district. 
The parasite Eurytoma parva Phillips had "barely begun issuance. 
Joint worms and E. parva were all out on May 26, adult joint 
worms being rather scarce and E. parva the more numerous. In 
late May the parasite Pitroninotus aureoviridis Cwfd. was still

■ A TENEBRIONID BEETLE ( Blapstinus gregalis Casey) 
Montana 
Nebraska 
Utah 
G. A. Mail (June 5): I would like to report that the tene- 
brionid 3. gregali s is this spring doing considerable doomage 
to vvheat in central and western Montana. In certain sections 
they are so numerous that under each clod of earth in a field 
there will be 15 to 20 beetles, and a conservative average in 
areas where they are doing the most damage would be 100 to 
the square yard. Both spring and winter wheats are being at- 
tacked and the insect is also recorded as attacking sugar 
beets. The beetle seems to be widespread but tne localities 
where the most severe injury is reported arc north of Great 
Falls.
