S ummary .1 It has been shown that adults and nymphs of the Jassid, Empoasca solaria DeLong, are able to eject diastase into the feeding medium. 2 This diastase, besides being secreted in the salivary glands, is apparently also formed by certain yeasts which are regurgitated from the gut of the insects. 3 A technique is described for feeding the leaf‐hoppers on a liquid. 4 The insects have also been shown to be capable of secreting an enzyme, probably invertase, which has the power of inverting pure sucrose.
