The larva of Leicester's bamboo-breeding anopheline “asiatica” as Stanton says (1912) has not, been previously described, although Leicester himself mentioned in his monograph that it was characterised by the possession of a very conspicuous black marking on the thorax shaped like a Maltese Cross; so having recently obtained a batch of seven of these creatures from a cut-bamboo at Ginting Simpah, the pass between the Native Malay States of Selangor and Pahang which is at an altitude of 1500 feet, I will attempt to fill the deficiency in our knowledge, adding as well a few notes on the biological side of the subject.
