-In- 
dicated. that the active season was complete. New-generation adults 
arc now in aestivation and will remain inactive until late in Hoven— 
her and early in December. Owing to the abundance of sour clover 
the past season and the heavy production of adults on this host, adult 
populations are considered larger than at any tine since the discovery 
of the weevil in 1939 • It is believed, however, that populations are 
insufficient to cause more than slight damage to a few alfalfa fields 
adjacent to most heavily populated aestivating sites. 
SWEET CLOVER 1CEEVIL ( Sitona cylindricollis Fahr . ) 
Illinois. W. P. Flint (May 24); The sweetclover weevil has caused heavy 
damage in the northern fourth of the State. Adults have been taken 
in about the northern half of the State. No commercial dar.ie.ge has 
occurred, except in the northern fourth to third. 
Minnesota. A. G. Rugglos (May 19 )• The swectclover weevil is quite abund- 
ant around Saint Paul and Minneapolis. 
North Dakota. F. G. Butcher (May 23)1 A weevil tentatively identified 
as the sweetclover weevil lias been reported in northern tern Pembina 
County near the Canadian border* Apparently this is the first record, 
although evidences of its injury have been observed during the last 
few years. A few young sweetclover fields have been seriously in- 
jured by the adults. 
CLOVER ROOT WEEVIL ( Sitona f lave seen s Marsh. ) 
Michigan. R. Hutson (May 2l): The clover root curculio lias been very 
troublesome, feeding on sweetclover on the experimental plots at 
East Lansing. 
CLOVER SEED CATERPILLAR ( Laspeyresia intorstinctana Clem.) 
Delaware. J. H. Aries (Hay 19 ) ; A field of red clover at Townsend, in 
New C-stle County, was severely damaged by the clover seed cater- 
pillar. A bout 70 percent of the buds contained larvae which were 
one-half to full grown* An occasional pupa was found. Examination 
of a field, near Dover, Kent Comity, showed the insect present but 
not quite so numerous. 
ALFALFA CATERPILLAR ( Co lias eury theme Bdv.) 
Utah. G. F. Knowlton and assistants (April 30 ); Alfalfa butterflies are 
present in the Uinta Basin. 
California. A. E. Michelbacher (May 22); In the northwest portion of the 
^an Joaquin Valley larvae are increasing in numbers. On May 15 the 
number collected in the different fields ranged from 0 to IS. In the 
area adjacent to the San Francisco Bay the larvae are still scarce. 
Only a very few larvae were found to be parasitized.
