NOTES ON THE HEMIPTERA. 247 pronounced spots in them on the upper wings. Abisko specimens altogether brighter than Swiss and Pyrenean. K. liifi'a, var. adijte. — I follow Lampa in classing my series from Abisko as this form ; but save that they are smaller than the type, I see little superficial difference. Aiujiades comma, var. catena. — Common, but much worn, at Abisko. From the brighter green of the under side, no doubt referable to this variety. The GeometridaB which I brought home have been most kindly identified for me by Mr. L. B. Prout, and are reported by him as follows : — From Abisko : Acidalia fumata, Larentia truncata, L. muni-tata, L. hastata var. subhastata (very common), Zanclognatha sp. ?, and a Pyralid sp. ?. From Alten : Larentia munitata, L. cmsiata, L. vionta-nata var. lapponica, L. hastata var. subhastata, L. albulata, L. incursata, and PyymcEna fusca. Oxliey Grove, Harrow-Weald. BIBLIOGRAPHICAL AND NOMENCLATORIAL NOTES ON THE HEMIPTERA.— No. 6. By G. W. Kirkaldy. (A.) My kind friend Mr. Prout has been so good as to send me brief notes on Gistel's ' Naturgeschichte der Thierreiche ' (1848), a work scarcely dealt with as yet in hemipterous literature. Mr. Prout tells me that, owing to Gistel's peculiar views on nomenclature, it is impossible for one who is not a specialist in Hemiptera to be certain of indicating accurately the hemipterous contents of the work. The following few notes, however, will be of interest to workers in this order, and it is to be hoped that the hemipterous portion will be made fully known very soon. The Hemiptera are discussed on pp. 148-51 and in the Preface : — (1). II Platycoris, Gistel, p. 149 = Pyrrhocoris, Fallen, 1814, type apterus. (2). Eupheno, Gistel, I. c. = || Macrophthalmus, Laporte, 1832 ; =: \\ Macrops, Burm. 1835 = Caridomma, Bergroth, 1894 ; = Sorglana, Kirkaldy, 1900. (3). Cheilocace, Gistel, p. 150, type regince-noctis. Genus not valid, as it is not described apart from the species. (4). Mylpha, Gistel, I. c, n. n. for " Poeciloptera," the reason apparently not being stated. (5). Cyphoma, Gistel, p. 151 = Dorthesia. The latter is altered because it is a personal name ! (6). Estphonia, Gistel, p. viii = Acrooera (!), Spin. I pre-sume Gistel means Aroccra, which is apparently not preoccupied or otherwise invalid.
