Anopheles sineroides may be considered as the intermediate type of A. hyrcanus var. sinensis and A. koreicus as regards the important characteristics distinguishing themselves from each other, as shown in the following table. [table] Patches on the costal vein of A. sineroides are the same with those of A. koreicus. Dark patches on the 6th vein of A. sineroides are the same with A. koreicus in number and the same with A. hyrcanus var. sinensis in position (Fig. A-C). In the current investigation, larvae of A. sineroides were bred in warm (28℃-33℃) and cold (14℃-19℃) chamber and variations in the patches of wings of hatched out adult mosquitoes were carefully examined. The larvae of which the outer clepeal hairs have 10-24 branches were selected and bred in the cold or warm chamber stated above. Among 22 adult mosquitoes obtained from the cold chamber, almost all were the typical sineroides-type; in only 3 specimens, the basal white patch was absent. Almost all of 20 adult mosquitoes obtained from warm chamber, showed marked and constant variation in the patches of costal vein. That is to say, in 16 specimens, both the basal and cubital white patches disappeared and in remaining 4 specimens, the cubital white patch was present. No variation occurred in the middle and apical white patches nor in the dark patches on th 6th vein except in 4 female specimens in which the apical white patch disappeared. (Fig. D). Thus the costal vein of A. sinercides bred in the warm chamber showed quite the same patches as in the A. hyrcanus var. sinensis. I am of the opinion that A. sineroides is quite akin to A. hyrcanus var. sinensis and it is doubtful whether the former is valied to be a distinct species.
