In this paper, the writers intend to describe a new subsbecies of Glenea (s. str.) chlorospila Gahan and its pupa from the Izu Islands, and to discuss its distribution. The host plant of the larva is Shiia Sieboldi Makino, which has not been recorded. Glenea (s. str.) chlorospila izuinsularis subsp. nov. (Fig. 1) =Glenea hachijonis Matsumura et Matsushita, Insecta Matsumurana, vol. vii, no. 3, p. 110 (1933). =Glenea chlorospila (nec Gahan) Ohbayashi, Trans. Kansai Ent. Soc., viii, p. 117 (1939). This new subspecies is closely allied in general appearance to the typical form, but can easily be distinguished from the latter by the following characters : Body and legs more slender, antennae of both sexes relatively longer, shoulder strongly projecting outside, two longitudinal protuberances from humerus to apex of each elytron more strongly carinate, elytra strongly attenuated towards apices, spine of the apex of each elytron much longer and more sharp. Silvery green discoidal fascia of the prothorax distinctly wider ; silvery green spots of the elytra not circular, spreading longitudinally along the suture and very often connected forming fasciae. Holotype : 1♂, Izu-Hachijo Is., June 5, 1951 (Coll. K. Umeya). Allotype : 1♀, Izu-Niijima, July 27, 1952 (Coll. K. Umeya) ; 1♀, Izu-Hachijo Is., August 14, 1950 (Coll. I. Fujiyama). Paratype : 1♂, Izu-Hachijo Is., August 14, 1950 (Coll. I. Fujiyama) ; 1♂, Izu-Hachijo Is., August 14, 1950 (Coll. I. Fujiyama) ; 1♂, Izu-Hachijo Is., June 11, 1951 (Coll. K. Umeya) ; 1♂, Izu-Hachijo Is., April 12, 1952 (Coll. M. Okamoto).
