Subfamily LEFT A ULACINAE. 



This subfamily occurs throuj^diout the tro])ical parts of the Indo- Australian region. 



Genus LEPTAULAX, Kaup, 1868. 



incl. Lcptaidacides , Zang, 1905. 



The characters used by Kuwert in his tables, especially those by which he 



divided the genus up into groups, have unfortunately proved to have, for the most 



part, no taxonomic value whatever. After eliminating the characters which are either 



worthless or of varietal value only, very little is left. In the following list I have 



grouped as best I can, with the help of the little that does remain, the names of such 



species as I am miable to recognize, under the names of such as appear to be distinct ; 



but in places the process has been little better than guess-work. Fortunately the 



principal zoogeographical results of this process are free from the doubts to which the 



synonymmy must remain open, as most of the synonyms fall under the names of 



L. dentatus or L. bicolor ,\ioth. of them species of whose wide distribution and variability 



there is abundant proof of quite a definite nature. 



The subfamily Leptaulacinae is found in all parts of the Indo-Australian region 

 inhabited by Passalidae.
