Missouri L. Hasem.an and P. H. Johnson (April 21): The clover leaf 
weevil is very abundant at Columbia. Most of the weevils 
were full-fed and had begun to spin cocoons April 15. 
ALFALFA CATERPILLAR ( Eurymus eurytheme 3oisd. ) 
Utah G. F. Knowlton (April 23): A few alfalfa butterflies 
are present in the fields in northern Utah. 
CLOVER ROOT BORER ( Hylastinus obscurus Mar sham) 
Oregon L. P. Rockwood (April 15): Adults were flying on March 28 
when the maximum temperature reached 82° F. This is the 
earliest date ever recorded for the flight of this species 
at Forest Grove. 
WESTEEN SPOTTED CUCUMBER BEETLE ( Dlabrotica soror Lee . ) 
Oregon D. C. Mote' (March 28): 3. G. Thompson reports Dlabrotica 
soror Lee. present in young clover fields in considerable 
numbers. 
T. R. Chamberlin (April 15): Adults are not so numerous 
as usual in Washington County and have not damaged the stands 
of seedling clover appreciably, 
PEA APHID ( Illinoia nisi Kalt. ) 
Kansas R. L. Parker (April 24): The pea aphid is appearing in 
large enough numbers to cause an outbreak under favorable 
weather conditions. 
Utah G. F. Knowlton (April 28): The pea aphid is still very 
scarce on alfalfa and peas in Davis County- 
Nevada G. G.iSchweis (April 18): Alfalfa aphids are reported 
as very abundant at Reno and Minden. Severe injury in small 
acreages has occurred in these two outbreaks. 
Oregon L. P. Rockwood (April 15): Very little vetch was seeded 
early enough in the fall of 1929 to become infested in the fall. 
In one young crchard where vetch was seeded in August 1929, 
much vetch was killed by a heavy aphid infestation in October 
and November. In March and early April, 1930, Illinoia pisi 
was making a slow start on this vetch, apparently owing to the 
fact that very few aphids survived the winter. There ^ere 
from 25 to 100 aphids per sweep here April 11. Coccinellid 
adults of several species averaged from 10 to 100 per sweep. 
Spiders were very numerous. Alfalfa fields are lightly in- 
fested, 30 to 100 per sweep on April 5. Coccinnelids and 
spiders were numerous on alfalfa also. Stem mothers of the 
aphid were scarce on Scotch broom in Clackamas County in late
