 This treats of the cankerworms {Fahacriia rernata aud Anisopifryj: 

 pometaria), the grape cane -borer {Amphivcrns bicaudatus), the grape 

 leaf folder (Desmia maculalis). the grapevine fidia {Fidia viticida) and 

 the bagworm {Thyridopteryx ephemerafiormis). With the exception of 

 notes upon the bagworm. the article is almost entirely a compilation, 

 descriptive of the insects and their life histories. The bagworm is 

 reported as doing much damage. Spraying with London x>wilde or 

 Paris green is recommended; also the addition of a little lime to the 

 arsenite spraying mixtures. 



On the parasites of the diseased and healthy silkworm ; contri- 

 bution to the study of flacherie, grasserie and pebrine, I. Kras- 

 ILSHTSHIK \ Memoirs !Soc. Zool. France, 9 {l'^9fJ), \\ pp. 513-5:^:2).— In 

 this contribution, after a few critical remarks, the author proceeds to 

 point out the difierences between Streptococcus pastorianus and Staphy- 

 lococcus insectorum and to describe Bacillus hofmanni, Micrococcus lar- 

 darius, and a new property of the corpuscles of pebrine. 



Streptococcus pastorianus difl'ers materially from Staphylococcus insec- 

 torum in its manner of multiplication and in the appearance of its 

 cultures and in the fact that it liquefies gelatin. During multiplica- 

 tion there is often produced a dijilococcus and each of these elongates^ 

 tinall}" producing a small chain of cocci, each of which ultimately 

 divides in the same manner. 



Staphylococcus insectorum increases in size while maintaining its 

 spherical form until finally a partition api>ears, dividing it into hemis- 

 pLeres, without one separating from the other. Sometimes a partition 

 perpendicular to the first also appears, dividing the entire spherule 

 into four cocci. 



Experimentation determined that Streptococcus pastorianus is the 

 true cause of flacherie. It first gains entrance into the intestine and 

 then passes through the walls of this to the blood, in which it forms 

 pure cultures. It is folk)wed by Staphylococcus insectorum and by 

 Bacillus hofmanni, both of which are found in the intestine of the 

 healthy and normal animal. 



Like Streptococcus pastorianus, the micrococcus of grasserie (Micro- 

 coccus lardarius) li(piefies gelatin, and during development sometimes
