Forest entomology . m a photograph of this species on Ribes sanguineum,found at Lyham, Northumberland.

Pupation takes place towards 22-4 FOREST ENTOMOLOGY. the end of August, the males appearing in September. They thenfertilise the females, when the latter moult again for the third commences shortly afterwards, and the insects remaindormant until the spring. Egg-laying takes place at the end of Apriland throughout the early part of May. In all probability the periodshere set forth may vary slightly, according to the season. The male (fig. 213), copied from Newsteads Monograph, is describedas dusky reddish-crimson or blackish-crimson in colour, with black eyes:. Fig. 213.—Male of Pulvinaria.

Two very long caudal filamentsat posterior end. Length, including caudal filaments, 2 to 3 mm. Having in a general way referred to the characters and life-historyof the genus Lecanium, it may now be best to give the salient char-acters of the arboreal species, according to Newstead.
