436 DK. F. LEUTHNEE ON THE ODONTOLABINI. 



When Hope described this species he had only the female before him, two specimens 

 of which, supposed to be from North India, are in the Museum at Oxford. It was 

 not until many years afterwards that Saunders brought the male to Europe, and 

 described it under the name of 0. emarginatus (Eeich. MS.), being probably misled by 

 the erroneous habitat ; and almost at the same time Westwood published the telodont 

 form under the name of 0. evansii. Parry recognized the specific identity of these 

 forms, which I am enabled to confirm by examination of the types.

Male. Deep uniform black, head and prothorax dull, elytra with an obsidian lustre ; 

 licad short and broad, upper side generally impressed ; front edge straight or slightly 

 emarginate, with no frontal crest; clypeus with triangular epistoma; canthus straight, 

 narrow ; the spine behind the eyes prominent and generally straight ; prothorax broad, 

 longer than the head, front edge very deeply emarginate on each side ; sides nearly 

 trispinose, but the front spine very slightly indicated : in the priodont form the front 

 angles are rounded off; under-surface of the prothorax with the sides smooth or with a 

 longitudinal elevation ; prosternal process generally round or triangular ; mesosternal 

 process very slightly developed ; front tibise not much longer than the four hinder 

 tibise, with the terminal fork strongly developed, and with three, four, or five spines on 

 the outer margin above it ; upper side with distinct rows of punctures. 



Mandibles. 



1. Forma telodonta (figs. 1, 2). — Mandibles as long as the head and prothorax 

 together, narrow, convex, rounded or flattened (fig. 2), flattened at the base and tip, 

 with three or four small teeth at the tip and two obtuse teeth at the base. 



2. Forma amphiodonta (figs. 3, 4).— Type ! 0. siva, Hope {true !). Mandibles as long 

 as the head, broad, with five small teeth at the tip and two at the base. 



3. Forma priodonta (figs. 5, 6). — Mandibles as long as the head, the sides convex ; 

 upper surface rounded and under-surface flattened; inner side with eight unequal 

 teeth, crowded together, and without gaps ; canthus frequently rather wide, the spine 

 behind the eyes but slightly developed ; prothorax rounded on the sides in front, as in 

 the female (compare figs. 6, 7). 



Female. Uniform black, head and prothorax dull, elytra shining; head broad, upper
