118 SANITARY ENTOMOLOGY 



Leptomonas muscae-domesticae (Burnett) is a parasite of Mtuca 

 domestica Linnaeus, M. nebulo Fabricius, Farmia scalaris Fabricius, 

 PoUenia ribdis Robineau-Desvoidy, Teichomyza fiusca Macquart, Lucilia 

 sp., Pycnosoma putorium Wiedemann, Scatophaga lutaria Fabricius, 

 Neuroctena anilis Fallen, Homalomyia corvma Verrall, and Sarcophaga 

 murus, undergoing complete metamorphosis in the bodies of the flies. 

 Patton (1910) has demonstrated that the disease may be transmitted 

 from fly to fly as follows: the food becomes infected from the feces of 

 the infected flies which have fed on it ; uninfected flies may become in- 

 fected by ingesting either the long flagellates, the short encysting forms, 

 or the cysts, in the feces of other flies, or in food contaminated by other 

 flies. 



Leptomonas pycnosomae Roubaud is a parasite of Pycnosoma 

 putorium. 



Leptomonas roubaudi Chatton is a parasite in the Malpighian glands 

 of DrosophUa confusa Staeger. 



Leptomonas sarcophagae (Prowazek) is a parasite in the gut of 

 Sarcophaga haemorrhoidalis Fuller and another species of Sarcoph- 

 aga. 



Leptomonas sotulanensis Roubaud is a parasite of Pycnosoma 

 putorium. 



Leptomonas stratiomyiae (Fantham and Porter) is a parasite of 

 Stratiomyia chameleon Linnaeus and S. potamida Meigen. Fantham and 

 Porter (1916) proved it experimentally pathogenic by inoculation to 

 Mus mus cuius. 



Leishmania tropica (Wright), the cause of ORIENTAL SORE of 

 man, may be taken up in the crithidial stage by Musca doTnestica and 

 the organism demonstrated 48 hours after feeding, according to Carter 

 (1909). According to Wenyon (1911) who investigated BAGDAD 

 SORE, Mu^ca domestica may readily feed on the sores and take up 

 Leishmania, but there is no development of the organism and no parasites 

 were found in the feces. On the other hand. Row, working with CAMBAY 

 SORE believed the organism transmissible by Musca domestica up to 

 three hours after the fly had fed on infected sores. He found the gut con- 

 tents of flies infective for a monkey three hours after the fly had taken up 

 Leishmania, but Patton (1912) maintains that Cambay sore never com- 

 mences in a cut, scratch or abrasion, and failed to transmit the disease 

 in this manner in numerous experiments with Musca v^hulo and Mu^ca sp. 

 A new investigation, however, is warranted by Row's statement, seeking 

 fecal infection of wounds. 



Rhynchoidomonas luciliae Patton is parasitic in the Malpighian 

 tubules of Musca nebulo and Lucilia serenissima.
