 .387. 



Three species of Anophelines occur in Denmark : — Anopheles plum- 

 bciis, which is rare ; A . bifurcalus, which lives for preference in the 

 forests and bites at nightfall ; and A. maculipennis, which when the 

 present study was undertaken was almost undiscoverable. Two 

 years' study of A . maculipennis has shown that this species lives all its 

 life in stables and outhouses, only leaving them for mating and ovi- 

 position, feeding always on domestic animals and attacking man only 

 in default of cattle. The chain of events that has led to the disappear- 

 ance of malaria in the country where it was formerly so prevalent is 

 briefly touched upon [see preceding papers].

 chez la Chenille de Galleria. — C. R. Soc. Biol., Paris, Ixxxv, no. 

 24, 2nd July 1921, pp. 224-226. 



Pursuing the investigation of the immunity of Galleria mellonclla 

 to various microbes, further experiments were made, such microbes as 

 Proteus, Bacillus coli and the cholera vibrio, all of which are highly 

 virulent to the caterpillar, being used as vaccines. Immunity was again 

 easily obtained. It was also found that protection against fatal 

 doses could be assured within three hours of the injection of the vaccine, 

 and that weak doses of the latter acted more rapidly than strong ones. 

 Furthermore, the caterpillars transmit their immunity to the resultant 

 moths.

 bes de France. — C. R. Soc. Biol., Paris, Ixxxv, no. 24, 2nd Julv 

 1921, pp. 226-228. 



A flagellate, held by the author to be Leptomonas davidi, Laf., was 

 observed by him in Etiphorbia esula var. mosana and E. helioscopia 

 from Maine-et-Loire, this being the first record of Leptomonads 

 in Euphorbia in France. 



The various published papers on Leptomonad infection in Euphorbia 

 are mentioned with references.

 Macq. (Dipt.). — Miscellanea Ent., Uzcs, xxv, no. 9, May-June 

 1921, pp. 65-66. 



Simulium cinereum, Macq., is recorded as causing discomfort to 

 cattle and horses while out in pasture in March, by continually attack- 

 ing the inside of their ears. It is suggested that it may possibly convey 

 certain diseases, such as foot and mouth disease and other septic 

 infections. To prevent attack a diluted sohition of cresol shoiild be 

 applied to the cars of animals put out to pasture during this season of 

 the year.
