The following formulae are said to be suitable for dealing with 

 Eriosoma lanigefum : — Fuhrmami's solution, containing 1 part lubri- 

 cating fish-oil, 1 part horse fat, 3 parts spirits and some rock salt ; 

 tobacco-lye solution, prepared by boiling 5 lb. tobacco in 3 gals, 

 water and adding 3 gals, of water in which 5 lb. of soft soap has been 

 dissolved ; and Krosig solution, prepared by boiling 7| lb. tobacco 

 in 3-4 gals, water, letting this cool and after removing the tobacco 

 leaves, adding 22 spoonsful of 5 per cent, carbolic acid, The infested 

 areas must be scraped and then painted with one of these solutions. 

 The scrapings must be burnt.

The remedy recommended is a varnish prepared by dissolving resin 

 in ordinary spirits. This is painted on, and after the solvent has 

 evaporated, the fine coating that remains prevents the Aphids from 

 moving.

Insect infestation in pine cones may be expected to be most severe 

 when the seed crop has been decreased by external conditions. In 

 the dry year of 1911 late frosts occurred in May and June and up 

 to 50 per cent, of the scanty crop of spruce seed from Styria and 

 Salzburg was infested by the larvae of Megastigmus abietis, Seitn., 

 a new species distinct from 31. strobilobius, Ratz. From fir seed 

 M. piceae, sp. n., was taken ; all stages of this species are described. 

 Cypress seed from Dalmatia yielded 31. ivachtli, sp. n., already 

 recorded by Wachtl in the seeds of Cwpressus semper virens. 



The paper concludes with a key, mainly based on colour characters, 

 to the 16 species of 3Iegastigmus in the author's collection, most of 

 which were bred by him.

In Hungary the flight period of Pyrausta nubilalis begins in May 

 and is over by July. The caterpillars are abundant early in July, 

 the author having found the first batches of eggs on a maize leaf on 

 5th July from which the caterpillars hatched on 10th July.
