Remarks on Hymenoptera and Coleoptera

1. I have proposed (cf. Deyroll’es Naturaliste. VI. p. 559, 15 Nov. 1884) to substitute the generic name Darala Ritsema (Notes Leyd. Mus. VI (1884). p. 81, Hynienoptera: Larridae) nec Darala Walker (List Lepid. Ins. Brit. Mus. IV (1855). p. 886, Lepidoptera: Bombycidae) by Dalara. 2. Xylocopa Forbesii Kirby ♀, from the Timor-Laut Islands (Proc. Zool. Soc. London. 1883. p. 344) = coronata Smith (Journ. Proc. Linn. Soc. Zool. V (1861). p. 135) from Kaioa (Brit. Mus.) and Halmaheira, Batjan and Ternate (Leyd. Mus ), the different iridescence of the wings, the only difference mentioned by Mr. Kirby, not being of specific value, as the specimens in the Leyden Museum, although doubtless belonging to one and the same species, show considerable variations in that respect.
