DR. F. LEUTHXEK ON THE ODOXTOLABINI. 455 



3. 



This insect was collected by Delessert in tlie Neilgherry Mountains, and was described 

 by Guerin as Lucanus Ucolor, 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 0. licolor (Guerin and Burmeister ') and sometimes as that of 0. rjazcUa 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, whicli agrees very well 

 ■with Guerin's figure in colour and markings.
