On the Bornean species of two Families of 
COLEOPETRA. 
Two recent papers* have supplied me with details 
for the following remarks, which are of interest in so 
far that they place on record the present extent of our 
knowledge of the Bornean species of these two beetle 
families, besides indicating the lines of relationship 
between the Bornean Insect Fauna and that of neigh¬ 
bouring countries. 
(i) Bornean Hispidce. In 1902 only 39 species of 
this family were known from Borneo. This number 
is increased in Dr. Gestro’s latest paper to 59, twelve 
new species being described from Sarawak material. 
The author writes : “ Dali' elenco generale delle specie 
“ che faccio seguire, appare che sopra un totale di 59 
“ specie, 34 sono particolari a Borneo, mentre il resto si 
“ ritrova nella penisola di Malacca, o nelle varie isole 
“ della Sonda e sopratutto a Sumatra.” Of the remaining 
25 species (one of which, by the way, being found in 
Labuan and Borneo only, should be included in those 
peculiar to Borneo) 5 are peculiar to Sumatra and 
Borneo, 7 more to Sumatra, Malay Peninsula and 
Borneo, 3 to Sumatra, Java and Borneo. None are 
peculiar to Java and Borneo. Of these 24 species no 
less than 19 occur in Sumatra, 11 in the Malay 
Peninsula (including Burma) and 8 in Java. One 
species occurs in the Philippine Islands and two in 
Mentawei. 
The above figures show: (i) a large proportion of 
species peculiar to Borneo, (ii) a close relationship to 
Sumatra and in a lesser degree to the Malay Peninsula, 
(iii) a markedly small relationship with Java and the 
Philippines. Though, as Dr. Gestro points out, further 
collecting in these countries will undoubtedly show 
more Bornean species, so that these figures will need 
certain modifications, yet they produce the same con¬ 
clusions arrived at by other writers on different branches
