Taylor (F. H.). Culicidae from Papua. — Trans. Entom. Soc, 

 London, pt. 1, 25th June 1914, pp. 185-205. 2 pi. 



Up to the present, only nine species of Culicidae have been 

 recorded from Papua. In the present paper 21 species are mentioned, 

 including Neosquamomyia breinli, gen. et sp. nov. Other new species 

 are Stegoniyia ornafa, S. atra, Lepidolomijia Jineata, Leuconujia {?) 

 albitarsis, Taeniorhyfichus papuensis, Melanoconion papuensis, 

 Uranotaenia nigerrima, Hodgesia triangnlata. It is hoped to make 

 a complete mosquito-survey of Papua.

In recording five cases of fever among the European population of 

 six persons on the Residency Hill, the author mentions that mosquitos 

 were fairly plentiful around their bungalows, examples being found 

 of Culexfafigans, C. tigripes, Stegoniyia fasciata and Ctdiciomyia sp. ; 

 no Anophelines were found (December and January). Sandflies were 

 also numerous and troublesome at dusk, but were not caught and 

 identified. The author was not attacked by any febrile illness, though 

 his bungalow was also infested by mosquitos ; sandflies, however, were 

 rare.

The author publishes the results of a few experiments in the hope 

 that workers abroad, where experiments on a practical scale are possible, 

 may be induced to try naphthalene as a deterrent to the breeding 

 of mosquitos. 



Flake naphthalene sprinkled on the surface of water imparts a shght 

 flavour to the water, but if suspended above it, so that no contact 

 takes place, this defect is obviated, and the author thinks that the 

 method may also prevent the presence of such species as Stegoniyia 

 fasciata in houses. For the author's experiments, half-pint jars were 

 used, wet blotting paper was placed on the bottom and the naph- 

 thalene scattered on this. Trial was made of 1, 0'5, 0*2 and 01 grammes 

 in the jars — 10 adult Culex pipiens were introduced into each and 

 secured liy covering the jars with net ; in each case a control jar without 

 naphthalene was used ; the capacity of the jars was 330 ccm. In all 

 cases at the end of less than 20 hours the insects were all dead or 

 dying ; the controls withstood confinement for over 60 hours. The 

 author next experimented with larvae, using two square-bottomed 

 troughs with a surface of 462 centiraentres, into each of which 4 litres 

 of strained rain-water were poured. A square frame, 15 centimetres 

 above the surface of the water and covered with netting, was placed 

 over each trough, and 100 Culex larvae (86 in penultimate and 14 in 

 final instar) were placed in each ; 1 gramme of flake naphthalene 

 was scattered over the surface of one trough and both were placed near
