(levelo})ini>', mid if cases of human plagaie slioiild occur it is not 

 always correct to ascribe tliem to importation. There appears to 

 be a certain relation between tlie number of fleas per rat and the 

 occurrence of rat pla<;ue and consequently the rat flea census is 

 important as a warning. 



EoDiiAix (Dr. .1.) & Uequaekt (Dr. J.). Nouvelles observations 



sur Aucliuicioiinjia Jitifohi, Fabr., et Conlnlohia anthro-

Aitrh nierorni/ia luteola, F. — This fly is distributed throughout 

 the whole of the Belgian Congo and occurs all the year round. It 

 lias only been met with inside or in the immediate vicinity of 

 dwellings, and the species is considered to be as specific a parasite 

 of man as is Clinoeoris (Cimex) lectularius, L. Its dispersal from 

 one village to another probably takes place in the e^^ or larva 

 stage in the dirty mats which the natives take about with them. 

 At Bukama, where the vSleeping Sickness Mission took up their 

 quarters on a hill covered with scrub from which all traces of 

 human occupation had vanished, the fly was frequently met with 

 in the newly constructed huts within three weeks. . 



Everywhere where the soil was slightly damp and not too 

 hard, numerous eggs were found in the dust, their shape and 

 characteristic markings making them easily recognisable. The 

 young larvae emerge from the e^g by a longitudinal fissure 

 extending from the pointed end to half the length of the egg. 



Cordylohia autJiropophafja, Griinb. Tliis species is _ very 

 widelv distributed in Katanga, but appears to be very rare in the 

 higher parts of the country, especially at Elisabethville, where, 

 for a period of several months, no case of cutaneous myiasis of 

 man or domestic animals came under notice. On the other hand 

 cases were exceedingly common in the region of Lake Mweru, 

 where several Europeans have been attacked by the cayor worm. 

 At Lukonzolwa, in January 1912, all the domestic rabbits were 

 infested with larvae of Cordylohia, the testicles and posterior 

 paws being frequently attacked. Dr. Eanchon saw a cayor worm 

 in a facial tumour of' a negro at Pweto. Larvae were found m 

 dogs at various places, and once in a captive wild cat (Felis cali- 

 qciia) ; while of a herd of sixty-one goats that came to Sankisia 

 five were suffering from myiasis. Human myiasis was observed 

 in three natives from Kalengwe, and Dr. Van den Branden was 

 twice enabled to observe attacks upon himself. 



All the recorded cases occurred in the rainy season ; at Katanga 

 numerous cases were observed between October 23rd and March 

 2Tth but there was none in the dry season. The fly probably 

 deposits its eggs Avhere there is a smell of animal or human 

 perspiration. The infection of animals probably proceeds from 

 the ground; as this is the only way to explain the position of the 

 tumours, which are almost always found on parts of the skm
