The President read a statement as to the death of a number of distinguished Russian entomologists during 1916-20. Prof. Poulton exhibited varieties of Pyrameis cnrdui, and an example of a very large Papilio, P. homerus F., that visits the very small flower of Asclepias curassaviea ; examples of Libythea, probabh' L. larus from Tangan-yika Territory, congregating perhaps before or during migration; notes on the courtship of Mtinomotarpa itisiynis Distant ; Coprid beetles believed to be internal parasites, and expressed the view that such cases were due to trickery on the part of native medicine men. Comments were made by the President and Mr. Durrant. ]Mr. Ilonisthorpe exhibited a specimen of Aryynnis ei/phro-syne carrying a portion of the pupa case. Some discussion arose as to the effect of damage to antennae on the flight of biitterllies. Dr. Gahan exhibited examples of the larvae of Phytodecta viminalis, and called attention to the existence in these larvae of eversible glandular structures between the seventli and eighth dorsal segments. Comments were made by Mr. C. B. Williams, who said that he had found P. viminalis to be viviparous. Mr. Morice exhibited: — (1) examples of Anthophora jjilipes, of which he had seen no ^ $ , and described attempts made by the S to pair with $ § ot the Humble Bee ; (2) a S sawfi}', Teiithredopsis pahnnta Geoffr. with an abnormal wing neuration, apparently a reversion to a primitive type.

MORTON, E.E.S. Plate II. In addition +o the Odonata from Mesopotamia and North-Western Persia mentioned in the "Entomologist's Monthly Magazine," 1919 (pp. 143-151, 183-196) and 1920 (pp. 82-87), a considerable number of other Neuroptera (in the Linnean sense) were collected by Bnxton and Evans. The true Neuroptera, Mecoptera, and some additional Odonata are recorded in the present paper. Through the kindness of Mr. Water-ston, I have also examined a collection made by Lt.-Col. H. D. Peile, I. M.S., in Mesopotamia, Kurdistan, and West Persia, presented by him to the British Museum, and containing some interesting species not represented in the other collections.
