( -i-l ) THE LEPIDOPTERA OF 13URU. PART \.— i;iior.\T.och:E.\. By W. J. J10LLANI1, Ph.D., Lh.D., F.Z.S., F.E.S., etc., Clianeellor of llie M'fslrrii Unhfrsili/ of Penttsylrama, unit Dirfctor of the Cariinjie ^funeuiii, Pittslntftjh. ri~^)lE iskuil of Biini (>5ouroii, Bouro, Boeroe) is situated .aiijiroximatolv ii> J-lat. :r LV to :i 5iJ' S. and loii.i;-. 120° to 1'..'7 15' E., reckoned from (ireeiiwicb. According to von Carnbei-it lias an area of 348T square miles, covering tbereibre an area about three-lnnrtlis the size of tlie state of Connecticut. It belongs to the Dutch Residency of Ainl)oyna, and is divided into twelve regencies subject to tlie general control of a deputy appointed by the Resident of Aniboyna. The deputy has his residence at Cajeli (=Kajeli = Kayeli) on tlie eastern coast. The ]iort of Cajeli in 1804 was declared free to the shi])s of all nations. Tiie island is mountainous in the interior, the highest i)eak, Tomahoe, rising to an elevation of 8029 feet above the level of the sea. The seaboard districts are alluvial and marshy in many jjarts. The island is traversed by a multitude of small streams, having a short but rapid course from the interior to the sea> very few of them being worthy of being designated as rivers, except the Cajeli, or AVai Apoe, whicli is navigable for a short distance. In the western portion of the island is a large sheet of water, Lake AVakoholo. with a circumference of thirty-seven miles and a width of two miles, which appears to occujiy the crater of an extinct volcano, at an elevation of I'.iUO feet above sea level. Jlnch of the island is covered with scattering forests, and the lowlands with tall marsh grasses. The si)il where cleared is fertile. (Joffee and cacao are extensively cultivated. Trojiical fruits abound. The principal artiide of export is cajeput oil, distilled iVom the leaves of Jlejalenca cajapnti, which is extensively used as a ])anacea throughout the lands of the Malays, and ])0ssesses valne as an anti-spasmodic and sudorific, and is reputed to be a specific in rheuraati<; affections, when a])plied externally. The flora of the island is very rich. Tlie mammalian fiiuna is not extensive, but interesting. The avifauna, on the other hand, is of considerable extent^ and includes a number of sj)ecies p<'culiar to the island. Tlie natural history of Burn has received attention from a number of travellers and explorers ; Forbes and Wallace being the only ones who have written at any great length npoii tiic subject. Very little, has been written upon the \Lfjtit/ojjf<-i(i. Boisduval in tlie \'o'/age <li-L' Astrolabe mentions a number of sjiecies found upon the i.sland. Wallace in several papers describes species of his collecting as new to science, and in the jiapers of a number of other authors' there are occasional references t(i species found here. The entire literature of the subject does not, however, furnish a hundred references to species distinctly known lo belong to the fauna of Bnni. Mr. Wallace a])])arently did not do very well in his collecting upon the island excejit among the I'ieridac, Kiihu failed almost entirely, and Forbea did not accomplish much. It was left to Mr. William Doherty, the intrepid naturalist explorer of the Malay Arcliiiielago, to make the first considerable collection which lia^i ever been made niiou the island. U])on this collection, which was gathered iu December of 18iil and January c;l' is'.jj, the following paper is based.
