This insect was collected by Delessert in the Neilgherry Mountains, and was described 
by Guérin as Lucanus bicolor, var. delessertii, from a female specimen, but it long 
remained an uncertain species. As the females of the Odontolabini are very similar, 
and are very difficult to distinguish from one another, it was sometimes regarded as the 
female of O. bicolor (Guérin and Burmeister’) and sometimes as that of O. gazella or 
cuvera (Westwood’ and Thomson”), until the careful examination undertaken by Major 
Parry, with the assistance of Count Mniszech, determined it to be distinct. I found 
male forms in Major Parry’s collection, but they have hitherto remained undescribed. 
There is a female in the same collection, from the Neilgherries, which agrees very well 
with Guérin’s figure in colour and markings.
