The method of securing a pure culture of Herpetonwnas pyrrhocoris, 

 obtained from Pyrrhocoris apterus taken near Paris, and the forms of the 

 flagellate are described.

Pentatomid bugs, found on cabbages near Bologna, included Eury- 

 dema {Pentatoma) ornatiini, E. ornatitm var. pectorale, E. (P.) olera- 

 ccimi, and Aelia acuminata. With the exception of the last-named, all 

 these species frequently harbour flagellates {Crithidia, and sometimes 

 Herpetomonas) in their digestive tubes, and very occasionally also 

 in the salivary glands and proboscis. The faeces of these insects 

 contained many flagellates and leishmanifomi bodies. The larval 

 stages also were infected. The plants on which bugs were numerous 

 showed yellow and dying leaves, and it was thought possible that the 

 flagellates might penetrate into the tissues. Tests of affected leaves 

 showed that this was probably the case, the parasites presumably 

 penetrating the tissue of the plant by means of the puncture made by 

 the insect or with the faeces. 



M. Roubaud, commenting on this paper, remarked that he had 

 previously found similar infections of cabbage bugs on two occasions. 

 More than 90 per cent, of the bugs {E. ornatum) then examined were 

 found to be parasitised, though no salivary infection was noticed. 

 No flagellates could be found even in plants that were black with 

 punctures of the bugs, and he therefore was of opinion that flagellosis 

 of the cabbage does not actually occur, the wilting of the plants being 

 due to the numerous punctures of the insects.

Previous work on the discovery of flagellosis in Euphorbia is briefly 

 reviewed. Patton, in a recent paper [R.A.E., B, x, 72], has made 

 the interesting discovery that in cases of kala-azar a small lesion is 

 noticeable at the point of inoculation, as in flageflosis. Adie and 

 Patton have pointed out that one phase of the cycle of Leptomonas 

 donovani is, like that of Trypanosoma lewisi, intracellular, and it is 

 thought that L. davidi may also have an intracellular phase in 

 Stenocephalus. Research is being conducted on these lines, the author 

 feeling convinced that the study of the evolution of L. davidi will 

 contribute to the elucidation of the problem of kala-azar.

In view of the great interest presented by the facts described by 

 Paillot [R.A.E., A, ix, 234] with regard to the immunity of inverte- 

 brates, similar experiments have been carried out by the authors, 

 using Galleria mellonella infected with cholera vibrio.
