This South-Indian species was described by Hope, in 1841, from a single male 
example, and was long regarded by Westwood, Burmeister, and Parry as a mere variety 
of O. cwera. Subsequently Major Parry and Mr. C. O. Waterhouse obtained speci- 
mens of both sexes from Travancore, and were thus enabled to recognize it as a distinct 
species. Through the kindness of Messrs. Janson and Moore, and especially of Mr. 
Kirby, who put me into communication with the Rev. S. J. Pettigrew, who lived for 
some time in Travancore, I was enabled to examine eleven male and five female 
examples.

Male. Uniform black, except the bicolorous elytra. Head often as broad as the 
prothorax, the sides with coarse shagreened punctuation; canthus broad, divided by an 
indentation into two folds in front of the eyes, the spine behind the eyes set very far 
back, and often rounded off; prothorax with the front edge deeply emarginate on 
each side, sides S-shaped as far as the middle spine, and then strongly emarginate ; 
prosternal process conspicuous, projecting vertically downwards; elytra orange-yellow, 
with a triangular black mark, rapidly narrowing before the tip; rim of the elytra black 
beneath ; front tibie long and straight, with one or two very slender spines above the 
terminal fork. 
Mandibles. 
1. Forma telodonta.—Mandibles longer than the head, rounded, strongly curved, and 
bifurcated at the tip, with three or four small teeth on the front branch; a rudiment of 
an obtuse tooth on the upper side at the base. Front margin of the head very convex 
(fig. 5). 
2. Forma mesodonta.—(a) Mandibles not forked at the tip, with three or four teeth ; 
beyond the middle is a very prominent tooth, pointing downwards, above which are four 
or five small teeth. A strong obtuse basal tooth (var. pectinata, fig. 6). (6) Mandibles
