in spring and early summer, while the adult occurs from June to 

 Januar}'. Exceptions to this rule occur. 



In the author's opinion this beetle is carnivorous, but not particularly 

 useful, while it may be a great nuisance in dwellings. Zacher has con- 

 cluded that the larvae and adults cannot live on uninjured grain and 

 die unless other food is available, that they cannot live on animal 

 remains (exuviae of flour-beetle larvae, etc.), but that they can live 

 on coarse ground grain.

In spra\'ing experiments against Clysia amhigiiclla, Hb., and Polv- 

 chrosis botrana, Schiff., it was found that the scorching that occurred 

 was not due to potash soap or Bordeaux mixture, but to the excess 

 of injurious inorganic salts in the Hungarian tobacco lye mixed with 

 these substances. Hungarian nicotine sulphate never caused injury. 

 Careful spraying for the first or spring generation is a successful 

 measure against these pests. On the other hand, treatment against 

 the second or summer generation is useless. Some good results were 

 achieved with a dilute petroleum emulsion, 1 jxirt in 10 of water.

The woolly meadow-moth, Hypogymna morio, L., injures grami- 

 naceous plants on flat pastures in the Hungarian lowlands. If very 

 abundant it may attack the seeds of cereals growing near by. There 

 is only one generation a year. The adult flies from mid-]\Tay to earh^ 

 June. The larvae rest during summer, autumn and winter under- 

 ground or under dead and dried stubble. The\' begin feeding early 

 in spring and continue doing so till mid-May. When the grasses 

 have been devoured, wheat, rye, etc., are attacked. The best remedial 

 measure is the free use of a brush harrow at the proper times ; this wnll 

 destroy large numbers of the larvae. Data on the losses caused in 

 Hungary are given in a series of graphs.

No injury to grape flower-clusters was observed in 1917 when 

 spraying was done with the improved Hungarian tobacco lye of 1917 

 (Thanaton), or with diluted petroleum emulsion. Such tested insecti- 

 cides may be used at any stage of development of the clusters against 

 the first generation of Clvsia ambiguella, Hb., or Polychrosis botrana, 

 Schiff.
