Eurydema oleraceum has done considerable damage of late years 

 in several parts of Sweden. It was known as a pest by Linnaeus, who 

 described an outbreak of it in 1760. Cabbage and turnips are preferably 

 attacked, but occasionally also potatoes, cereals and ornamental 

 plants. The adult hibernates under vegetable refuse, which should 

 be destroyed. In May and June the females deposit their ^gs on the 

 leaves in characteristic clusters. The egg-stage lasts about one month, 

 and the new brood is full-grown in late summer. Collecting and 

 spraying are recommended as methods of controlling E. oleraceum, 

 and according to Lampa, a 4 per cent, solution of lysol is very effective, 

 killing the insects in a few minutes. As spraying is apt to injure the 

 tender shoots, it must be applied with caution. The best result is 

 obtained from two sprayings with an interval of from 3 to 10 minutes.

Outbreaks of Lophyrus ]}ini (pine sawfly) are reported from many 

 parts of Brandenburg and Silesia. Spraying with petroleum soap 

 emulsion and the collection of the larvae are the best means of controL 

 On an estate near Danzig, in 1905, about 150 acres were cleared of 

 1,412 litres of larvae (=5,600,000 individuals) at a cost of about 

 £8 165. Od. ; in 1906, about 75 acres were cleared of 201 litres ( = 800,000 

 individuals) at a cost of about £1 7^. Of?.

Lachnus glehnus, sp. n., often occurs in great numbers on Picea glehni, 

 Mast. (Japanese dwarf silver spruce). The trees upon which this species 

 was found were imported from Japan and it is possible that the insect 

 was imported with them. Phyllaphis coiveni, Cockerell, is common 

 on the leaves of manzanita, producing conspicuous red galls during 

 late summer and early autumn, which are the result of the attacks of 

 the stem-mothers. The distribution of this species is wide and 

 apparently coincides with that of the food-plants. It occurs in the 

 Rocky, Sierra Nevada and Coast Range Mountains. In California this 

 Aphid is probably most abundant in August. The most important 

 natural enemy is an Anthocorid bug. Callipterus hellus, Walsh, occurs 

 on the undersides of the leaves of Quercus agrifolia, in the southern 

 part of the State. In the eastern States, this species has been taken on 

 Q. rubra, Q. coccinea, Q. macrocarpa and Q. alba.

During the summer of 1915, the larvae of Luperina {Apamea) testacea 

 appeared in several localities in Denmark and injured grasses, such as 

 Festuca elaiior, at Roskilde in July, oats atLyngby in May, and Dactylis
