weeks and feed on the grass. They hibernate in the ground, and 

 begin feeding again in the spring, and continue until June, when 

 pupation occurs in the soib The adults emerge in July, and are 

 still on the wing in August. Remedial measures should be carried 

 out in the autumn and spring, and should consist of removing all 

 moss from the grass by means of sharp harrows or rakes and the 

 burning over of infested meadows. Repeated grazing should reduce 

 the number of caterpillars.

The Psyllids that are most destructive in Austria are Psylla mail, 

 Schmidb., on apples, and P. pyrisuga, Forst., on pears. Although 

 P. pjricola, Forst., occurs, as does also P. pyri, L., the damage 

 done by them is of minor importance. The remedial measures 

 advoc&ted include a dormant spray of 10 per cent, carbolineum, 

 nicotin?: sprays and kerosene emulsion, for which formulae are given.

The Coccids dealt with include Lepidosaphes ulmi, L. , L. pinnaeformis, 

 Bch., Aspdiotus ostreaeformis, Curt. {Epidiaspis betulae, Bar.), and 

 Aulacaspi: pentagona, Targ. Remedial measures include sprays of 

 lime- sulphur, petroleum emulsion or carbolineum. 



The artficial distribution of Prospaltella berlesei, How., has greatly 

 reduced tie numbers of Aulacaspis pentagona in various districts of 

 Austria, aid the Coccinellid, Novius cardinalis, has proved to be a 

 useful natiral enemy of Icerya purchasi, Mask. A key is given to 

 the indigeious species of Coccids.
