 Lymantria dispar.] — C.R. hehdoin. Seances Acad. Sciences, Paris,

The microbes parasitic in the larvae of Lymantria dispar here 

 described are a Coccobacillus provisionally identified as Bacillus 

 lytnantriae, Diplococcus lymautriae, sp. n., which is only slightly 

 pathogenic to the caterpillars, and Bacillus liparis, sp. n., which 

 resembles the diptheria bacillus and is more pathogenic to the larvae 

 of L. dispar than Diplococcus lymantriae.

The small spider, Theridium weyeberghii, Holm., has been found to 

 cause considerable damage to lucerne plants by weaving a thick web 

 over them. The spider works with great rapidity, covering many yards 

 of lucerne with its web in a few hours. The web can be removed by 

 lightly sweeping over the crops with branches of trees, to which the 

 webs will cling, but the spiders should be destroyed by spraying 

 with a very fine spray, using one of the following insecticides : | lb. 

 lysol to 25 gals, water ; 2 parts acaroina to 100 parts water ; 3 parts 

 kerosene to 100 parts water ; 8 lb. tobacco juice to 20 gals, water.

 of Aspidiotus hederae on Hedera helix ; A. pinicola, sp. n., found on
