254 ADELOTOPUS JACOBSONI, 
NOTE XVI. 
A JAVAN SPECIES 
OF THE GENUS ADELOTOPUS HOPE 
(Coleoptera: Carabicidae) 
DESCRIBED BY 
C. RITSEMA Cz. 
The Leyden Museum has recently received a small col- 
lection of Coleoptera from the island of Java, brought 
together and presented by Mr. Edw. Jacobson, Among 
these beetles [ found a specimen of a species of the genus 
Adelotopus Hope, belonging to the interesting family of 
Pseudomorphidae (Carabicidae), which species certainly has 
not yet been described. 
I am acquainted with the description of only two other 
species of Adelotopus out of Australia, viz. Adelotopus col- 
laris Waterh.') from Siam and Adelotopus papuanus Gestro *) 
from Papuasia. A third species, described by Waterhouse 
(l.c.) under the name of Adelotopus marginatus and origi- 
nating from Java, does not belong to the quoted genus 
but is synonymical with Cryptocephalomorpha Gaveret 
Rits. 3) from Java and Sumatra‘), and, after having com- 
pared once more the description of A. collaris with that 
of A. marginatus, I believe that collaris too belongs to

of beetles was a mixed one: it contained specimens from New Guinea and from 
Java (Macklot).
