owing to symptoms resembling those of malaria being noticed in some 

 individuals who had never been out of New Zealand. 



All the above findings point to the desirabihty of dealing with 

 mosquito-breeding grounds, at least in the more populated areas.

 on the Ceratopogonine Midges o£ the Gold Coast, with Descriptions 

 of New Species. Part 3. — Ann. Trop. Med. & Parasit., Liver- 

 pool, xiv, no. 3, 8th February 1921, pp. 309-331, 13 figs. 



In this continuation of a paper previously noticed [R.A.E., B, 

 ix, 25] several new species are described ; these are PrionognatJnis 

 marmoratus, gen. et sp. n., P. maciilipennis, P. psetidomaculipennis, 

 P. maculithorax, Atrichopogon xanthoaspidium and Stilobezzia spiro- 

 gyrae. The last-named is apparently the first species of this genus to 

 be described from Tropical Africa. The larvae were found associated 

 with an alga, Spirogyra sj).

 xiv, no. 3, 8th February 1921, pp. 333-340. 



The new genus, Ptilolepis, is erected with Musca inferior. Stein, 

 as the type. The work of various authors on the synonymy of this 

 species is reviewed and the characters of the new genus are described.

of Dirofilaria immitis in Dog Fleas, Clenocephalus felis and canis. 

 — Ann. Trop. Med. & Parasit., Liverpool, xiv, no. 3, 8th 

 February 1921, pp. 389-392. 



The fact that Dirofilaria immitis does not require a definite genus 

 of mosquito for the successful completion of its life-history led to 

 further investigations to ascertain whether this parasite could not 

 Complete its life-cycle in other ectoparasites, such as fleas. As a result 

 of observations here described the fleas, Ctenocephalus felis and C. 

 canis, were found to be effective intermediary hosts. In one case a 

 mature larva had penetrated the unbroken skin of a puppy. 



Garcia Banus (M.). Noguchi's Yellow Fever Research. — Lntemat. 

 Jl. Public Health, Geneva, ii, no. 1, January-February 1921, 

 pp. 50-60. 



A resume is given of Noguchi's investigation on the causal agent 

 of yellow fever. 



Among the reasons for regarding Leptospira icteroides as being the 

 organism concerned are its occurrence in and cultivation from yellow 

 fever cases ; inoculation of cultures of this organism reproduces the 

 disease in guinea-pigs, and the organism can be isolated from them ; 

 its properties and characteristics agree with those of the yellow fever 

 virus ; it is carried by Stegomyia [fasciata], and when thus carried it 

 reproduces the disease. 



The only proof of identity that is unsatisfied by Noguchi's work is 

 the reproduction of the disease in man by means of pure cultures of 

 the organism.
