The elimination of yellow fever from Guayaquil was planned in 

 1916, but postponed on account of the war, with the result that by 

 the beginning of 1919 this disease had been introduced into Northern 

 Peru and spread rapidly. 



In the control of the epidemic efforts were made to destroy the 

 breeding-places of Sfegomyia [Aedes argenteus, Poir.], isolate the sick, 

 and fumigate infected premises. The chief object was to prevent the 

 further extension of infection. The breeding-places consisted largely 

 of the water containers in houses, which were rarely emptied entirely 

 before refilling, owing to the scarcity of water. This made control 

 difficult, but eventually the Government arranged for the free dis- 

 tribution of water with good results. It was urged that these same 

 measures should be extended to healthy places in the south exposed to 

 infection, but unfortunately this was not carried out efficiently. 



Yellow fever was eliminated from the northern department, where 

 this campaign was undertaken, the last doubtful cases occurring in 

 September 1920, but had been found in epidemic form in January 

 well to the south, where it had existed for some months. The campaign 

 for 1921 is outlined, and if at the end of the year the disease is eliminated 

 from that district, Peru and the whole Pacific coast of South America 

 should be permanently free from it.

The experiments in inoculation with blood containing Plasmodium 



praecox {falciparum) here described furnish additional evidence that 



guinea-pigs, rabbits, and monkeys {Macaccus rhesus) are resistant to 



human malaria, and tend to support the conclusion of other workers, 



that they are not susceptible to infection.

X, no. 4-6, April-June 1922, pp. 51-60. 

 This group has no representatives in Europe. A key is given to the 

 adults of the seven species dealt with. The subspecies include Aedes 

 tortilis virginensis, n., from St. Thomas, Virgin Islands.

The two additions to the fauna of the Californian mountains are 



Ciilex territans, Wlk., bred from a grassy pool containing large numbers 



of Aedes cataphylla, Dyar, and a few A. palustris, Dyar, and A. 



impiger, Wlk., occurring in the same breeding-places as A. cataphylla.
