 Rpt*. [>'. fi.], 33 (1918), No. 49, pp. 2156-2169, fig. 1).— This is a report of 

 studies made near Montgomery. Ala., during the summer of 1918. It is pointed 

 out that as an agent in malaria transmission A. crucian* is not so important

 While rearing istopheles maculipennie and A. bifurcatue, the author observed 

 a spontaneous epidemic among the larwe and Isolated the bacillus here de- 



scribed from the cadavers. In th arae of 61 experiments with the iarv;p 



kept in water artificially contaminated with this organism the mortality varied 

 from 30 to SO per cent The virulence v I when the bacillus was 



isolated from a dead larva, infection appears to tnko place through coming 

 in contact with the bacilli at the surface and not through Ingestion. Cules 

 pinion* was found to be resistant to it.
