A LIST OF THE HOliEEAN 
species in the Sarawak Museum, and although per¬ 
sonally a stranger to the writer, he has proved an ever 
ready friend and adviser in the compiling of this list. 
I take much pleasure in using this opportunity to record 
my gratitude to him. 
M. Ch. Kerremans has kindly promised to write Part 
II. of this paper giving descriptions of all new species 
at present known (but undescribed) from Borneo. 
This paper should appear in the next number of this 
Journal; and with its conclusion all the known species 
of Bornean Buprestidae will have been enumerated. 
A few remarks on the geographical distribution of 
the Bornean species will be reserved for the end of 
Part II.

* M. Cli. Kerremans gives an interesting note on the flight of this insect in 
his paper on the Buprestidae of Sumatra ( Mem. Soc. Ent. Belg. Yol. vii, p. 
1, 1900). He writes, “tres commun, vole a la facon des Lucanes, le corps 
vertical; l’insecte tourne lentement sur lui-meme, s’elevant et s’abaissant 
alternativement.” 
Of G. bicolor , Fab. he says, “se tient habituellement au sommet des arbres 
les plus eleves.”
