A description and figure (of the var. minor) of this species have 
been already published by M. van Vollenhoven (loc. cit.) ; a second 
description of it, accompanied by a figure of the var. max., will 
probably not prove uninteresting. Numerous specimens of this 
insect were sent to England by Mr. Wallace and distributed 
among various collections. I may remark, that the black plage, 
both on the prothorax and body, are very variable, and in some 
specimens totally wanting. Of males with fully developed man- 
dibles but two or three were to be found, one of which is now 
figured.

I am indebted to Count Mniszech for the description and figure 
of the above; it appears to be allied to the Bornean species 
O. Brookeanus.
