 Some were attracted to Howering trees, which 1 was more successful in 

 Knding here. We could tell Avhich trees were in Hower high above our 

 heads, without being able to see a (lower, by llie buzzing of insect-life. 

 Whatever height the trees were the Dayaks would go to the top. 

 chuibing by the ci-eepers and rattans ; and they would cut off several 

 huge limbs covered with blossom for me to stand by and capture what- 

 ever chanced to come ; and they would staA^ up aloft and fill their ])ottles, 

 by shaking the insects on the great sprays of blossom into their nets. 

 The flowering trees which produced the most Coleopteru were Venionia 

 arhorea, 3£acsn sp., two species of Elaeocarpus, and two species of 

 Eugenia. The chief visitors to these trees were Ceramhycidae, Ela- 

 teridae, Cetoniidae, CiircuUonidae (including 21 species of Balauiniis, 

 probably nearly all ncAv), many small Breiithidae, Helota (a conspicuous 

 genus of Clavicornes), Malticidae, and Galerucldae. Along the jungle- 

 paths man}^ beautiful members of the genus Glenea {Lamiidae) were 

 met with, perhaps 35 species in all. Thi-ee specimens of the magnificent 

 Cetoniid, Diceros horneeiisis Wallace, Avere captured as they were flying 

 over mountain-tops, on three different occasions, and one fine S of 

 Diceros peteli Buquet. was taken in the same way, Avhich shows the 

 difficulty of taking a series of these active insects. The Riitelidae must 

 also be numerous, but are equally hard to find, only seven species of 

 Parastasia were taken — two were dug out of very rotten wood, 

 P. epliippiu)n Voll. and the other probably no-v. sp. ; F. ^-muculata 

 Wat. was captured on a flowering-tree, Eugenia, sp. ; and P. con- 

 Jluens West., the commonest, came to light. It w-as on a jungle-path 

 at Quop that I met with the remarkable Orthopteron, Condylodera sp. 

 (not C tricondijloides West.. Avhich I have taken in. Javal, a j^erfect 

 mimic of Tricondyla cyariipes Esch., subsp. cavifrons Sch. I had a 

 good look at it on a leaf by the side of the path, and thought it was 

 the Tricondyla until 1 had it in the bottle ; I took five specimens of the 

 Tricondyla, wdiich is probably a common insect, in the same place. 



After leaving Quop 1 made a most interesting expedition with 

 Major J. C. Moulton, who has written an account of it in the 

 " Zoologist," 1914, pp. 361-374, 414-431, up the Sadong Eiver, then 

 to Mt. Merinjak near the Dutch border, and across country to the head- 

 waters of the Sarawak lliver, and down to Kuching. The great majority 

 of the Coleoptera taken at Merinjak were again new to me, which goes 

 to show how every hill and mountain in a great island like Borneo must 

 be thoroughly explored before we have any idea of the tremendous wealth 

 of species the island will produce. Wallace during his stay in Borneo
