[Malaria and AJaopheline Topography in Argonne in relation to 

 an Epidemic of Indigenous Malaria.] — Bull. Soc. Path. Exot, 

 Paris, xii, no. 1, 8th January 1919, pp. 23-34. 



The outbreak of malaria occurring in Argonne in 1917 has recently 

 been described [see this Review, Ser. B, vii, p. 41]. Its chief peculiarity 

 lies in the fact of its extension and of its being the first epidemic in 

 this region after 4 years sojourn therein of colonial troops, vectors of 

 malaria havingbeen numerous in the region throughout then- occupation. 



Anophelines constitute, during June to August, fi'om 6 to 8 per 

 cent, of the mosquitos in Argonne. The two indigenous species, 

 Anopheles bifurcalus and^. mamli])ennis, occur almost in equal numbers 

 in the evening at the edge of woods, where they bite frequently. 

 During the daytime, while A. bifurcatus only appears occasionally 

 about habitations, remaining almost exclusively in the woods and 

 only constituting a danger to those who enter them, A. maculipennis 

 is common in houses. A. jylumbeus {nigripes) is also found in Argonne, 

 though rarely, as in other parts of France. 



In view of the presence of numbers of men who had become exposed 

 to attacks of malaria while on the various battle-fronts, and of the 

 density and ubiquity of the Anophelines, the outbreak of malarial 

 attacks is less sui'prising than their relative rarity. Perhaps the 

 reason for this may be found in the check exercised on the parasite 

 by the inclemency and uncertainty of the climate in Argomie. Against 

 the local mosquitos, control measures would probably prove 

 impracticable and unsatisfactory.

 pp. 35-51. 



Observations are recorded from the laboratory of the hospital at 

 Duala in 1917 and 1918. Microfilariasis is general among the adult 

 population of Duala and the forest region of the interior. Microfilaria 

 loa and Filaria loa are very frequently found and the author's observa- 

 tions have convinced him that the former is the embryonic form of 

 the latter. Microfilaria perstans, the characteristics of which are 

 described, occurs in numerous cases and is often associated with 

 M. loa ; the adult form has not been traced. The connection of these 

 two parasites with the cases of elephantiasis so frequent in the vicinity 

 of Duala is discussed. The adult form, F. volvulus, with the embryonic 

 form, M. volvulus, is found in tumours, but cannot be traced in the 

 peripheral blood.

 on Lipoptena cervi, L.] — Zeitschr. Forst- u. Jagdwesen, Berlin, 1, 

 no. 6, June 1918, pp. 268-272, 10 figs. 



This is one of a series of entomological communications from the 

 Royal Forestry Academy at Eberswalde and contains figures and 

 morphological notes for facilitating the identification of Lipoptena 

 cervi, L., a Hippoboscid fly infesting the red deer.
