• The external characters of the larva and pupa of Glyphipteryx semiflavana Issiki (1930) are described in this paper. The larva is characterized in the following points. Epicranium with an additional seta behind and mesad from P1. Adfrontals with a single seta on each side ; AFa not found. On prothorax SC1 absent. On meso- and metathorax ST group unisetose. On 9th abdominal segment, T2 and SS-setae missing, and T1 as minute as microscopic setae. Spiracles projecting, those of prothorax forwards, while the remainder backwards ; spiracles of 8th abdominal segment located on dorsal surface. Ventral and anal prolegs rudimentary, without crochets. Anal proleg, dorso-caudal margin with a tiny sclerotized process before distal corner. The host plant is a bamboo-grass, Pleioblastus variegatus Makino var. viridis Makino (Gramineae). There is one generation annually. The adults emerge from the middle of April to late in May. The larva bores into the culm in which it lives and eats. The winter is passed as a fully grown larva. Pupation takes place from early in April to the middle of May in the culm. Addendum : I have examined the following Glyphipterygid larvae : Choreutis bjerkandrella Thunberg, Brenthia japonica Issiki, Anthophila pariana Clerck, A. japonica Zeller, A. hyligens Butler, A. sp. (larva on Debregeasia edulis Weddell), Glyphipteryx semiflavana Issiki, and Lamprystica igneola Stringer. In the larva of each of these, except L. igneola, seta T2 is absent on the 9th abdominal segment. In that of L. igneola, seta T2, however, is present on that segment ; this is not a Glyphipterygid character. An examination of the adult genitalia shows that it is doubtful whether L. igneola belongs to the Glyphipterygidae or not.
