The author finds that observations published by him in 1915 

 generally agree with those independentl}^ made by Strindberg and 

 published at a later date, evidently without knowledge of the former 

 work. Attention is drawn to some important conclusions that may 

 be drawn from Strindberg's researches. The author's work dealt 

 with the viviparous species. Coccus {Lecanium) hesperidum, L., and 

 Aspidiotiis hederae, Vail., and with the oviparous ones, Pulvinaria 

 camelicola. Sign, [floccifera. Green), P. vitis, L. [hetulae, L.), Saissetia 

 [Lecanium) oleae, Bern., Eulecanium (L.) persicae, F., and L. corni, 

 Bch. Strindberg studied Saissetia (L.) hemisphaerica, Targ., an 

 oviparous species.

A new Chalcid, a species of Copidosoma, is recorded as parasitising 

 Depressaria alpigerella, Frey, on Laserpitiiim siler in the Engadine. 

 From 37 to 120 adults may emerge from one larva. This Chalcid is 

 attacked by the hyperparasites, Tetrastickus sp. and Pteromalus sp. 

 Other parasites of Depressaria are Eulophus ramicornis, F., Pezoma- 

 chiis sp. and Phaeogenes planifrons, Wesm.

As a result of spraying in 1920 some of the crops yielded from
