Mr. J. Wood-Mason on Mantis metallica. 35 
any rate very rare, in Kuropean collections, no specimens of it 
having been seen either by De Saussure or by Stal, the latter 
of whom makes not the slightest allusion to it in his ‘ Sys- 
tema Mantodeorum,’ while the former is able to do no more 
than place it next ‘after his Odontomantis javana, one of the 
two species to which it turns out to be most nearly affined, 
A second specimen has at last been obtained in the district 
adjoining that from which the first was received. It was 
captured in September 1881, on Nemotha, a peak of the 
North Cachar hills, which rises to the height of 3336 feet, 
by my native collector, by whom it was forwarded alive to 
Silchar, where I happened at the time to be stationed. 
The species belongs to the subfamily Harpagide of Stal’s 
system, and is very closely allied to Odontomantis javana, 
Saussure, and to Antissa pulchra, Fabry. It differs from the 
former, but not from the latter, in the discoidal vein of the 
wings being branched ; from the latter, but not from the for- 
mer, in the transverse ridge of the clypeus being angulated ; 
and from both of these species in its greater robustness, in its 
more firmly chitinized integument, and especially in the form 
of the prothorax ; on which last account | propose for its re- 
ception a new subgenus, which may be thus named and cha- 
racterized :— 
NEMOTHA, subgen. nov. 
Pronotum robust and tolerably broad, strongly constricted 
posteriorly ; the portion of it in front of the constriction oval ; 
the disk of its posterior lobe slightly inflated on each side ot 
the median ridge at the anterior end. Clypeus transversely 
elevated into a strongly angulated ridge. Frontal shield 
obtuse-angular at base, with the angle but slightly projecting ; 
its disk furnished with two short and widely separated ridges. 
Discoidal vein of the wings branched.

?. Head, legs, margins of the pronotum as far back as 
the constriction and a band running from the margins across 
the supracoxal groove, and the under surface shining black, 
with blue reflections like the blue-black paper used to cover 
pill-boxes, with all the articular membranes, two streaks on 
each eye, the middle two fourths of the first joint of the 
fore tarsi (this paler and greenish), a thick bracket-shaped 
mark at the posterior end of the second, third, fourth, fifth, 
and sixth abdominal sterna, all the soft and membranous
