A fe^'^ bean pod borers (I' s.rxca. testulalis Geyer) are 'be?;in"iing to 
appear a^-^ain in lima, beans, rearing January none of these insects were 
fouiid in lima beans althou,?!! some were seen in snap beans. 
A leaf beetle, Cerotoma denticornis Fab., lias been more abundojit in 
the spraj'^ed fields than in those v/here no attempt has been made at insect 
or fun^as control. 
I planted some Crotalar ia incar.a beside ray own lima beans here, and 
am just beginning to collect the seed now. Hot a single pod is infested, 
and indeed I have no record of finding gti.ella zinchenella caterpillars 
in lima beans, either mj* own or those on the Station grounds, since last 
December. I can not imagine what 'has happened to the insect, as our 
minimram temperatures are not nearly so lov; as in southern California, 
the means for December and January being 55° 
A lace ovig, Cor-'-thucha gossypii Pab. , has been present for several 
weeks in the more- wind-swept corner of one lima bean field, but is just 
now becoming s^iff iciently n'usj-aeroiis to cause appreciable damage. 
The midges ( Sciara sp. ) appeared in small numbers at light on the 
nig?it of February 24, but none h-ad been noted before, and I saw none on the 
night,. of February 25.

The coffee aphid ( Toxoptara a^irantiae Boycr) is abundant in the 
plantations now (February 3), but is doing relatively little damage because 
the season is not vcrj- dry, and the trees are holding the old leaves well.
