Citroen (S.). Anophelinensoorten te Soerabaja. [Anophelines found 

 at Soerabaya.] — Geneesk. Tijdschr. v. Nederlandsch- Indie, Bataviu, 

 Ivii, no. 6, 1917, pp. 763-766. 



In his preliminary report on Anophelines at Soerabaya van Breemen 

 gave a certain prominence to Anopheles rossi [see this Review, -^ev. B, 

 vi, p. 53] which may lead to mistaken conclusions being drawn. 

 Early in 1917 the author found in this district not only Anopheles 

 rossi, A. rossi var. indefinitus, A. sinensis, A. barbirostris and A. kochi, 

 but also A. ludlowi, A. aconitus and A. fuliginosus. 



A. ludloivi is very abundant ; its breeding places are nearly alwa5^s 

 the salt-water fishponds along the coast. In water where A. rossi 

 was breeding only 30-40 per cent, of A. ludlowi was present, but in 

 neighbouring houses the adults of A. ludlowi predominated, a fact 

 confirmed by Swellengrebel, who considers this mosc[uito to be more 

 especially a domestic species. A larva of A. ludlowi was only found 

 once in braclsish water in a bucket. Where the breeding places of 

 this mosquito surround markedly malarial districts and it piedominates 

 in the houses there, it is clear that it must be regarded as the most 

 important malaria carrier. As some specimens have been taken in 

 parts of Soerabaya far removed from known breeding places, this 

 mosquito probably breeds also in collections of brackish water. It 

 would also appear to breed in fresh water during the temporary 

 disappearance of salt-water breeding places in the dry season, so that 

 the existence of temporary breeding places on high, scantily watered 

 ground must be taken into account. A. aconitus occurs in various 

 places, and though not proved to have a marked influence on the 

 malarial incidence, it requires to be closely watched. Only one 

 breeding place of A. fuliginosus was discovered. This species was not 

 found indoors. Without disputing the importance of van Breemen's 

 discovery that A. rossi was found infected with malaria, it is pointed 

 out that there is no statement to the effect that the salivary glands 

 were involved, and an examination of only fifteen specimens is 

 insufficient to warrant the conclusion that this species is an important 

 carrier.

 Indie, Batavia, Ivii, no. 6, 1917, pp. 807-809. 



A description is given of Anopheles (Myzomyia) flavus, sp. n., from 

 adults taken near Soerabaya together with Anopheles rossi, A. rossi 

 var. indefinitus and A. ludlowi. The breeding places are unknown. 

 An Anopheline received from Penjaboengan appears to be identical 

 with this species, which is possibly an unmarked variety of A. rossi 

 var. indefinitus.
