456 DR. F. LEUTHNER 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 O. emarginatus (Reich. 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 ; 
head 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 tibia not much longer than the four hinder 
tibie, 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. 5, 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 conyex ; 
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 ,
