﻿390 The Philippine Journal of Science m* 



This species is reported in the Philippine Islands by Banks 

 (1906) and Ludlow (1908). In April of the present year we 

 found it breeding in a rice paddy in Laguna Province. 



James (1902) states that he has not carried out any feeding 

 experiments with this species. 



Tsuzuki (1902) infected Anopheles sinensis (jesoensis) with 

 the parasites of tertian malaria, and transmitted the infection 

 to a healthy person ; he believe it to be intimately concerned in 

 the transmission of malaria in Japan. 



Stephens and Christophers (1906) believe from its geograph- 

 ical distribution that Anopheles sinensis is of little importance 

 in the transmission of malaria. 



Stanton (1912) observed malaria zygotes in this species on two 

 occasions in the Federated Malay States, but was unable to infect 

 it under experimental conditions with the parasites of subtertian 

 malaria. 



Anopheles maculatus is a species whose identity has been very 

 uncertain. The synonymy of this species is given by Stanton 

 (1912) as follows: 



Anopheles maculatus Theobald, 1901. 

 Anopheles maculata Theobald, 1901. 

 Nyssorhynchus maculatus Theobald, 1903. 

 Nyssorhynchus willmori Leicester nee James, 1908. 

 Nyssorhynchus pseudowillmori Theobald, 1910. 



According to Stanton (1912), who has examined the type 

 specimens of Anopheles maculatus Theobald, this confusion has 

 arisen from the fact that the types are not male and female of 

 the same species, but represent distinct species, the male being of 

 the species known to oriental investigators as maculatus and the 

 female of the species known to them as karwari. Stanton pro- 

 poses to obviate this confusion by retaining the name maculatus 

 for the species which is now well known under that name to the 

 students in the Orient and to rename the species which had hither- 

 to been known as karwari. 



Alcock (1913) lists Anopheles willmori as a variety of Ano- 

 pheles maculatus. 



This species has not hitherto been credited to the Philippine 

 Islands. Mr. Banks, entomologist of the Bureau of Science, 

 states that he recently collected several specimens at Baguio, 

 Mountain Province, at an altitude of about 1,500 meters, but 

 the report of these has never been published. Anopheles macu- 

 latus is reputed to be essentially a mountain or highland species. 

 However, we have found it breeding to a limited extent in Laguna 

 Province, at an elevation of only about 100 meters above sea level.
