In the example of 0. Hageni, for which I am indebted to 

 M. Ritsema, the apex of the elytra has a slight sinuation near 

 the suture and an obtuse tooth at the suturai angle; the elytral 

 sculpture is the same as in 0. apiculatus, but the explanated 

 margin of the thorax is double the width that it presents in 

 that species. The apex of the elytral suture is not obliquely 

 truncated but quite straight. The species, as also 0. Hageni, 

 belongs to the small group of Chaudoir's Monograph, which 

 includes 0. insularis and Mouhoti.

A species of wide distribution and varying somewhat in size, 

 colour of legs and antennae and in the degree of obtuseness 

 of the hind angles of the thorax. I have examined specimens 

 from Java, N. W. Australia, Cochinchina, Bengal and Japan, 

 as well as the numerous series from various localities in Burma. 

 The original Javan type is distinctly shorter, the elytra more 

 tesselated with sericeous spots and the hind angles of the tho- 

 rax more distinct than in any of the others, but a N. W. Au- 

 stralian example and others from Saigon nearly approach it in 

 these respects. The Japanese form is nearly as briefly oblong 

 as the Javanese but is distinguishable by its decidedly shorter 

 antennae. In Burma the species is as a rule more elongate- 

 oblong, with often a brassy tinge and reddish antennae and 

 femora, the sericeous spots of the elytra visible chiefly near the 

 apex. Similar examples occur also at Saigon and in fact all 

 gradations exist.
