TI-JLK ANNALS MAGAZINE OF NATURAL -HISTORY. [NINTH SERIES.] No. 35. NOVEMBER 1920. NOV 2 3 1920 LT. — On the Oriental Members of the Coleopterous Group Macrodactylides (Melolonthidaj). By Gilbkrt J. Arrow, FZ.S., F.E.S. (Published by permission of tbe Trustees of the British Museum.) In his classification of the Melolonthidae ('Genera des Coleopteres/ vol. iii.) Lacordaire noted as a remarkable fact that an Indian insect, Dejeania alsiosia, 131., was the sole known non-American representative of tbe great Sub-tribe Macrodactylides. In the Ann. & Mag. for 1907 (ser. 7, vol. xix. p. 436), I announced that Dichelomorpha ochracea, placed by Burmeister in the Hoplides, was really congeneric with Dejeania, and that the latter name having been pre-occupied must be replaced by Dichelomorpha. I also referred to this genus a species (D. marginata, Nonfr.) wrongly described as a Hoplia. The number of described species allied to these is now fairly considerable, but they have been generally misplaced, so that the utmost confusion still prevails amongst them. Dichelomorpha ochracea, described by Burmeister in 1855, was again described by Boheman in 1858 as a species of Dichelus {chinensis, Boh.), and in 1900 Fairmaire transferred it under that name to yet another genus, which he named Sinochelus, adding two more species, which also belong to Dichelomorpha. In 1881 Sharp described a species from Ann. & Mag. N. Hist. Ser. 9. Vol. vi. 30
