Vol. XXviii] ENTOMOLOGICAL NEWS. 369 Indian Gall Midges (Cecidomyiidae, Dipt.). By E. P. FELT, Albany, New York. The writer has been privileged, through the courtesy of Prof. Ramakrishna, of South India, to study two small collections of gall midges reared or obtained from the vicinity of various grasses. In addition to data given in a preceding paper,* we would record the rearing of the rice or paddy gall midge, Pachydiplosis oryzac \Yood-Mason, from Panicnm stacminnm, and the capture of adults referable with very little question to this species, in light traps. The specimens taken in early Octo-ber, 1916, were heavy with eggs. Pseudhormomyia fluvialis Felt was reared, in addition to food plants previously recorded, from Panicnm piinctatum, and both this species and the closely related P. cornea are here referred to Dyodiplosis Rubs. Be-low we describe one new species and all the stages of a very interesting midge, the adults previously being unknown and ten-tatively referred to Oligotrophus Latr. Hormomyia ischaemi Kieff. 1910 Kieffer, J. J. Royal Botanic Gardens Kew, Bull., No. 3, p. 71. (Oligotrophus.) Adults and specimens of the gall of this insect, provisionally referred to Hormomyia, were received from Prof. T. V. Rama-krishna, Coimbatore, S. India, under date of November Q. 1916, accompanied by the statement that the insects were reared from a gall on Ischacmum pilosnm and were very likely iden-tical with the species described from the larva and gall by Dr. Kieffer as Oligotrophus ischaemi, which latter is probable though not certain. The larva described by Dr. Kieffer, if this species, is evidently a young stage, since the large size of the midges preclude their developing from such a small full-grown Irirva. Gall. Length II to 18 cm., diameter 3 to 4 mm. This is a reddish, cylindrical tube pointed at the apex and sheathed at the hase by scale-like leaves. The interior is hollow for practically its whole length and emergence is through a small hole near the tip (characters in part from L. A. Boodle, p. 70, /. r.). Egg. Length .2 mm., ovate, cylindrical, whitish and apparently pro-* Ent. News 28 73-76.
