SUMMARY.1 P. gahani has previously been recorded by Green as occurring upon Red Ribes, Ceanothus, Laburnum and potato tubers. This last record is here elaborated. 2 The female passes through five stages, while the male passes through six. 3 The life‐period in the two sexes is very extended, ranging between 20 and 24 weeks. 4 Owing to the long life‐period no fears should be entertained of this coccid becoming an economic pest.
