forgotten, and were subsequently redescribed under the names of O. nigritus and 
O. gouberti. 
Hope’s type in the Oxford Museum was said to come from Java (Cat. Lue. Col. p. 16), 
but this contradicts p. 5, where Silhet (Khasia Hills) is correctly given as the locality, 
as is proved by the label on the specimen, which I was enabled to examine through 
the kindness of Prof. Westwood. The same error is repeated in the registers of the 
British Museum, as well as in the Leyden Museum, which latter received a specimen 
from Hope himself. As the female of 0. siva is very difficult to distinguish from that 
of O. bellicosus, Cast., the females are much more frequently mixed in collections than 
the males. A recent consignment from Java, which I lately examined in the Leyden 
Museum, contained only forms of the latter species, which are easily distinguishable in 
the male sex. 
The range of 0. siva extends from North India (Silhet) across South China to 
Formosa. In the last locality it varies slightly from continental examples in both 
sexes, but so slightly that Messrs. Parry and Bates have been unwilling to treat the 
Formosan insect as a distinct species’.

Odontolabis bellicosus, var., Parry, Trans. Ent. Soc. Lond. 1870, p. 57. 
Male. Intermediate between Q. siva and O. bellicosus, but nearest allied to O. dal- 
mani, Hope. The whole body shining black, without hairs; head extremely finely 
punctured, quadrangular, the sides straight, spine behind the eyes directed forwards ; 
canthus narrow; prothorax trispinose as in 0. bellicosus, the middle spine most 
prominent; outer margins of prothorax beneath coarsely wrinkled ; prosternal process 
very strongly developed (figs. 1a, 2); mesosternal process similar, projecting forwards, 
and stronger than in 0. bellicosus or O. dalmani, but similar to O. celebensis; front 
tibize with two or three spines above the terminal fork ; all the legs with distinct rows 
of punctures. 
Mandibles. 
1. Forma telodonta.—Mandibles long, straight, rounded, flattened at the base and 
tip. Tip curved inwards with five small teeth ; base with two (fig. 1). 
Two specimens in the British Museum, and one in Major Parry’s collection. 
2. Forma amphiodonta.—Mandibles rather longer than the head, with five small 
teeth at the tip, and two or three at the base (fig. 2). 
One specimen in the British Museum. 
3. Forma priodonta.—At present unknown. 
Female. Shining black like those of 0. bellicosus and O. siva; head broad, strongly
