mealy bugs from a mosaic squash were transferred to a pot con- 
taining fourteen cow pea plants has resulted in 100 per cent in- 
fection. The pots were kept under an insect proof cage and 
were ringed with tree tanglefoot to keep other insects away. The 
checks remained healthy. These data are of interest, in addition 
to the fact that the disease was transmitted by the mealy bugs, in 
that the infection was from Cucurbitaceae to Leguminosae and 
gives added proof that mosaic can be transmitted to plants belong- 
ing to other families and orders.
