Abstract
The author has previously made descriptions of Japanese anopheline pupae. At that time several abnormalities were encountered in those specimens. Few case of pupal abnormality has been reported, and the author will hereby make brief descriptions about these examples. Number of specimens observed is given in Table 1. All pupal materials except for A. lindesaii japonicus were obtained by the rearing of larvae hatched from the eggs under the room temperature (about 20-28℃). The larvae of A. lindesaii japonicus were collected in mountain streams and were also reared to the adults in the same condition. The pupal pelts left alone in the water by emergence of the adults were preserved in a 10% formalin solution until the materials were gathered enough to be examined. Then the pelts were mounted in a gum-chloral solution and were observed under the binocular microscope.
