1902. ] SPIDERS FROM BORNEO AND SINGAPORE. 231 
It is frequently possible to pair a mimicking species with a 
definite specific model, but perhaps more frequently the mimic 
(either a Batesian or a Miillerian mimic) in its general appear- 
ance resembles a whole group of known distasteful insects; or, in 
other words, the general appearance of the mimic is typical of a 
distasteful group, rather than exactly similar to one definite 
species; and in these tables of mimetic Longicorns and their 
models I have by no means included all, but merely typical 
models. 
The diagrammatic tables of convergent groups of pseud- 
aposematic and synaposematic insects at the end of the paper 
include, however, all the known distasteful insects which serve as 
models in the respective groups. 
In the Appendices are described a new species of Butterfly, a 
new Moth, two new genera and several species of Longicorn Beetles, 
two new Clerids, and two new Brenthids. I owe the descrip- 
tion of all except the first-mentioned species to the kindness of 
Dr. Karl Jordan, Mr. C. J. Gahan, the Rev. H. $8. Gorham, and 
Dr. A. Senna. 
Professor E. B. Poulton, F.R.S., has added some interesting 
and suggestive remarks on my observations: these are scattered 
throughout the paper, but in all cases his initials are affixed. 
My task, in the absence of a large library and of named col- 
lections for comparison and reference, has not been easy, but I 
have received the most valuable and generous aid from Professor 
Poulton, whom I feel that I can never sufticiently thank. It is not 
too much to say that had it not been for his help this paper could 
not have been written. Most of the specimens here described 
and figured are now deposited in the Hope Museum, Oxtord, 
where they can be seen by all students of the subject. Iam 
much indebted to Mr. H. N. Ridley, Director of the Botanic 
Gardens, Singapore, for directing my attention to some interesting 
cases of mimicry observed by him and for some valuable notes 
thereon. Mr. Gilbert J. Arrow, Monsieur Jules Bourgeois, 
Mr. Malcolm Burr, Sir G. Hampson, Dr. F. A. Dixey, Dr. R. 
Jestro, the Rev.O. Pickard-Cambridge, F.R.8., Mr. R. McLachlan, 
F.R.S., Mr. W. L. Distant, Mr. C. J. Gahan, Dr. Senna, Mr. M. 
Jacoby, Col. Bingham, Mr. E. E. Austen, Mr. C, O. Waterhouse, 
Dr. Brunner von Wattenwyl, and Col. Yerbury have rendered 
much kind assistance in identifying many of the species noted m 
this paper, and to these gentlemen I tender my grateful thanks.
