A specimen, subadult female, of <I>Tadarida</I> was collected from Kumamoto City, Kyushu, Japan, by Dr. H. Tange in April, 1964. It is identified as <I>T. insignis</I> (BLYTH, 1861) and hence the third record for this species in Japan. If this identification is correct, <I>insignis</I> may not be a subspecies of <I>T. teniotis</I> but a distinct species differing in the following characters; 1) the wing membranes are only inserted to the lower third of the tibia instead of just above the ankle; 2) calcar with a distinct keel; 3) color of fur is fuscous, much darker than that of <I>teniotis</I>; 4) in the skull, zygomatic and lachrymal breadth are relatively narrower and the mandible is relatively longer than in <I>teniotis</I>; 5) lower incisors are strongly imbricated and the relatively larger second incisor extends to the middle of the inner lobe of the first incisor. The distribution of <I>insignis</I> is confined to China, Korea, southern Ussuri and Japan and clearly separated from that of <I>teniotis</I> by a broad region extending from Indo China and Tibet to Afghanistan.
