pupate. The beetles of the new generation appear in a fortnight 

 and attack late-flowering cruciferous plants diu-ing the rest of the 

 summer. Whether in favourable circumstances two generations a 

 year occur in Finland is not yet settled. 



As a remedial measure spraying the plants with arsenical sprays 

 as soon as the beetles appear is suggested. It is also easy to collect 

 the larvae and the beetles in various ways. Collection must be carried 

 out during warm and sunny weather, when the beetles are active, 

 and can be effected either with nets or with a funnel made of sheet- 

 iron with a bag tied at the bottom. A useful apparatus consists of 

 4 or 5 wooden boards attached by sticks 12-16 inches long to a pol4 

 about 6 ft. 6 ins. long ; the boards are covered with tar and a wire is 

 fastened in front of the pole. The pole is carried through the fields 

 by two men, so that the boards are drawn between the rows of plants, 

 and the larvae and beetles, disturbed by the wire touching the plants, 

 drop and are caught on the boards. The destruction of cruciferous 

 w^eeds is also a very important measure against this beetle, and the 

 keeping of bees has proved very eflective, since the bees disturb the 

 beetles when visiting the flowers, often dislodging them and thus 

 lessening the damage done by them to a considerable degree.

 [With a German summary.] 



A detailed account is given of the external morphology of this bug, 

 with special reference to the genital armature and the developmental 

 stages. In the summer of 1917 M. dolabratus occurred in great 

 numbers on cereals and grasses in many parts of Sweden. The leaves 

 and stalks become white as a result of attack and the spikes fail to 

 develop normally. The bugs were so numerous in many places that 

 about 200 individuals could be collected on an area of about 11 square 

 feet. They were found from May to July ; at the end of 

 June they were full-grown and oviposition then took place. The 

 females produce about 50 eggs, which are inserted by means of the 

 saw-shaped ovipositor into the stalks at the lowest joints. The eggs 

 hibernate and probably hatch at the beginning of May. There are 

 five nymphal instars and development is comj)leted in about six 

 weeks. The bugs mainly attack the borders of cornfields, since they 

 migrate from the meadows and the grasses growing along the ditches. 

 Numerous Nabids occurred in company with Miris dolabratus, 

 especially Nabis flavomarginatus, Scholtz, and N. ferus, L., and the 

 author believes them to be predaceous on it. 



Ploughing the attacked fields in order to destroy the eggs is suggested 

 as a remedial measure.
