them. Many of the species placed by Kuwert in the genus 
Macrolinus must be transferred to the genus Tiberius in accor- 
dance with Zang’s revised definition of the genera which is 
much better than Kuwert’s and which I am not yet in a 
position to improve upon although I think this will ultimately 
have to be done. ‘‘ Tiberius’’ kuwerti or cancrus is not a true 
Tiberius at all and must be made the type of a new genus of 
Aceraiinae as pointed out above. 
e next sub-family, to which the name Gnaphalo- 
cneminae may be applied, I include all Indo-Australian genera 
having true lateral scars on the mentum, having the supra- 
orbital ridges continuous with the transverse ridge at the back 
of the head and having only one pair of processes (often com- 
pound) developed from the anterior margin of the head between 
the supra-orbital ridges. Most members of this sub-family are 
found as far west as Tavoy, I have seen but a very small 
cuss its classification further here. The definition of it given 
above is not quite satisfactory, for a variety of the Aceraiine 
species Basilianus cantort is known to me in which certain 
sight the presence of scars. But as far as I can see the sub- 
family is a natural one, and I have not the material necessary 
for a full investigation of all its characteristics. 
_ The only remaining sub-family found in the Indo-Austra- 
lian region is the Leptaulacinae. It is distinguished from all 
the above-mentioned sub-families by the presence of two 
and Leptaulax ; but Zang has now split the latter genus into 
es. 
Stoliczka tells us that he found the study of this family 
of special interest from a zoogeographical point of view, 
though in his preliminary, and as it turned out his only paper 
upon it, he does not investigate this aspect of his subject very 
thoroughly. My own work, as a basis for which I have used 
the scheme of classification briefly outlined above, fully supports 
this view as I hope to be able to show more fully later, in a 
more.extensive paper.
