sculptured ; canthus broad, as in 0. dalmani; prothorax strongly convex and shining, 
the sides dull; upper surface extremely finely punctured; sides of the prothorax 
nearly trispinose, the front angles strongly developed, as in O. dalmani(¢ ); pro- 
sternal process rounded, spatulate; mesosternal process more strongly developed than 
in 0. bellicosus or O. dalmani; front tibie long, narrow, with four spines above the 
terminal fork ; hind legs very long, especially the tibie. 
One specimen in the British Museum.

Dr. Kaup described this species in 1868 from two males from Nias. One of these 
he gaye to Major Parry, who regarded it as a large variety of O. bellicosus with fully 
developed mandibles’, a view in which Kaup himself concurred when he subsequently 
visited England. When I examined Kaup’s type in Major Parry’s collection in the 
winter of 1882 I found that this telodont male agreed better with 0. siva and O. dal- 
mani in the shape of the head and mandibles than with 0. dellicosus. I was confirmed 
in this opinion by a series of three males and one female which the British Museum 
received from Nias with two male specimens of O. inequalis; and which Mr. C. O. 
Waterhouse kindly permitted me to examine. The mandibles of the three telodont 
specimens are exactly similar. The configuration of the prothorax and the unusually 
strongly developed pro- and mesosternal processes are equally constant.

Male. Very like that of the preceding species (0. gracilis), but smaller, Head, 
prothorax, elytra, and sometimes the legs clothed with fine brown hairs; under-surtace 
of the body smooth, or only very slightly hairy ; head quadrate, and rather flattened ; 
front edge strongly and semicircularly emarginate, the sides straight; canthus 
narrow; spine behind the eyes projecting slightly forwards ; prothorax trispinose on 
the sides (twice deeply emarginate); under-surface of prothorax with the outer margin
