With the exee])tiitii of the Tin-tricidw, 'rin:i<la.<!, auJ Pterophorida', which 

 were sent to Lord A\'alsingham, the entire collection made at this time came into 

 iiiv possession. At intervals of leisure I have devoted to it my best eftbrts, and 

 tliink that I have sncceeded in working it out with reasonable certainty. 1 am 

 es])ecially iudobteil to Sir (4eorge F Hampsou for invaluable assistanci! rendered 

 me iu the determination of the m)tli:^, whie'i formed a very large part of the 

 collection. 



A letter sent me by Mr. Doherty at the time he sent me the collection contains 

 some facts wliicli are of interest in regard to localities on the island, which he 

 visited. He says : " Bnru is assuredly a liard nut to crack. . . . Kajeli, the chief 

 j>ort, is a hopeless place for insects. I collec:ted a little at Labuan Barat, not far 

 from ^\■allace's place, Waipnti. But most of my work was done mncli farther 

 iin, on both sides of C!ape Saruma, the south-eastern point of the island, at Hat 

 (especially), Kusu-Kusu, Poli, and Wailawa. We collected up to about -Oijit feet 

 on Mount Lumara, at the liack of Hat. From Kajeli to Hat, my headipiarters, 

 it is two nights by ' prau.' We spent the intervening day at Labuan 15arat. The 

 weather was stormy, and the voyage most dangerous and exhausting : otherwise 

 we had a rather pleasant though fatiguing time, and did not lose a single day's 

 collecting. Our health was good during the whole time. The great objection to 

 this coast is that it is all high virgin forest, wholly witliout paths. Pieridae are 

 therefore scarce. The long walks were very hard on us. Generally in the morning 

 we plodded through the loose sand of the beach, jnmjiiug the streams, till wo came 

 to some big one which we ascended for miles (each taking his own). H raiued every 

 day at ',' p.m., so that in coming back the streams were generally in flood, and we 

 had to cross them waist-deep. Then the tide would probably be up, and we would 

 have to walk long distances in the water. Ou the whole, I think, i)utting moths 

 against butterflies, we did about as well as we could have in the dry season. I doubt 

 whether any locality in Burn is better than Hat, except the Wakoholoctuntry, which 

 is practically inaccessible, except for a few days' trip in light marching order, on 

 account of the want of coolies. The people of the country I visited ar>; Alfnros — 

 lieathen, very friendly, honest folk. They came down to the coast only a generation 

 ago, and the interior is now quite uninhabited excejjt at Wakoholo and on the Waijafo 

 liiver (where there is absolutely no forest). At the back of Hat is Jlount Lumara, 

 some six thousand feet high, covered with unbroken forests. Over much of this 

 country there are island-like masses, ridges of metamorphic limestone, jiierced by 

 thousand of caves, much as in Timor or the Malay Peninsula. Ajiart from this the 

 usual surface rock is micaceous sandstone, overlaying great beds of true mica-schist 

 exactly like that in the Alps. There is coal in the west, and Mount Tomahoe is 

 said to be volcanic." ..." The moths were all taken Viy beating, or at light. 

 Baits failed. When you thiuk that Dr. Platen only got eighty odd species in 

 fourteen months in Palawan, Hibbe and Kiiha one hundred and fifty in Aru in 

 twelve months, and Ribbe eighty odd in tieram in over four months, yon can see 

 tliat I am sending yon something quite out of the common order." 



It remains to be said that the species taken by Jlr. Doherty reveal a very close 

 affinity between the fauna of Burn and Amboyna. Hi the determination of species 

 much assistance has therefore been derived from the very thorough and important 

 papers which have ajipeared from time to time upon the lepidoptera of the latter 

 island from the pen of Dr. Arnold Pagenstecher, and also from the various papers 

 of the distingnished Dutch naturalist, P. (". T. Snellen of Rotterdam.
