As the findings of Mrs. Adie differed greatly from those of the present 

 authors [cf.R A.E.,^, ix, 209] it was decided to repeat some of the pre- 

 vious work [R. A.E., B, iv, 124, 174 ; v, 124 ; vi, 207]. The technique 

 employed during these observations is described. In no case was any 

 evidence of an intracellular stage of development of the parasite of 

 kala-azar found in the bed-bug. On a few occasions single bodies 

 that were indistinguishable from forms of the parasite were noticed 

 in cells, but they may have been parasites in the cells or artefacts. 

 Since the flagellates can multiply so freely in the contents of the stomach 

 and gut, it is thought there is no need for an intracellular stage ; 

 but the mere facts of flagellation and multiph cation do not suggest 

 an explanation, in the circumstances, of the use of the flagellum to 

 the parasite, nor the use of free multiplication in promoting the 

 continuity of its life-cycle. 



The presence of an obligatory intracellular phase would form strong 

 evidence in favour of the bug being the true insect vector of Indian 

 leishmaniasis, but if it is absent the bug should only be considered as 

 a casual host in which the parasite can only develop to a certain 

 point. 



Although it may be argued that the experiments described are not 

 quite natural, as the bugs were fed on cultures and not on infected 

 persons or animals, the authors are quite satisfied as to the results. 



No positive intraceUular development was obtained from oriental 

 sore experiments, although these were nearer natural conditions than 

 those referred to above. It is suggested that some other possible 

 vector be carefully investigated in connection with the transmission 

 of leishmaniasis.

Lucilia argyricephala, Macq. {serenissima, ¥.), is widely distributed 

 in India, and is met with at altitudes of 6,000 ft. It is commonly 

 found in bazaars, but never enters hodses. Oviposition occurs on 

 fresh meat, entrails and oft'al of all kinds, also in the bodies of freshly 

 killed birds, and to some extent in decomposing matter. This species 

 is attracted to shed blood, and can easily be bred by placing females 

 in cages with some "fresh meat. It rarely produces m^^iasis, and then 

 only in animals. The larvae have only been recovered from three cases, 

 all of which occurred in the Bombay Presidency. Owing to the 

 structure of the larvae, they are not well adapted to live in the tissues 

 of man or animals. 



This species is commonly infected with the flagellates, Rhynchoido- 

 monas luciliae in its Malpighian tubes, and Herpetomonas mirabilis 

 and H. muscae-domesticae in its ahmentary tract. The latter parasite 

 obtained from this fly has never developed into a Rhynchoidomonas , 

 though it has been cultured for months. 



Lucilia craggi, sp. n., is very similar in its habits to the European 

 blow-flies Calliphora erythrocephala and C. vomitoria. It occurs
