Some Additional Notes on Buprestidae found 
in Sarawak, together with a brief Comment on the 
Geographical Distribution of all the Species of 
Buprestidae now known from the Island of Borneq. 
By J. C. Moulton. 
Since the publication of the first part of this list in 
February 1911, many more specimens of Buprestidae 
have been captured and added to the Sarawak Museum 
collection, and amon^ them two species not before 
recorded from Borneo. To make our list as complete 
as possible the following notes are therefore appended. 
*3. —Chrysochroa (Catoxantha) opulenta , Gory. 
Eight examples of this fine species were taken one 
day in April (1911) on a. hill near Puak, Upper Sarawak; 
they were noted by the native collectors as flying very 
fast and high in the heat of the midday sun. 
5.— Chrysochroa (Megaloxantha) bicolor, Fab. 
A nice example of the nigricornis form of this species 
was taken near Kuching in March (1911). When fresh 
the following points were noted in its coloration :—lateral 
tubercles on pronotum rich yellow, bars on elvtra ivory- 
white and body beneath cream-yellow. 
In another example (without data) in the Sarawak 
Museum, the elytral bars are deep yellow, similar in 
colour to the pronotal tubercles, possibly due to some 
chemical change taking place in the pigment. Mons. 
Kerremans in describing the species (Monogr. Buprest., 
Vol. III., p. 22., 1908) mentions the tubercle on the 
pronotum as “ toujours blanc d’ivoire ou jaune,” the 
elytra, he says, are adorned with a transverse bar “ d’un 
blanc d'ivoire, cerclee de bleu,’' and the underside he 
describes as “ blanc d’ivoire ou jaune testace clair sauf 
les pattes.” It may be therefore of some slight value 
to record the coloration of a freshly killed specimen, i.e., 
* This and succeeding numbers refer to the numbers used in the 
first portion of our list of Bornean Buprestidae ( Sar. Mils. Journ., Yol. I., 
1911, pp. 157-183).
