Only two other species of the genus have been described from the Indian sub- 

 region. 0. brevirostris, Heller, from Ceylon, is of the same size, but has the rostrum 

 only as long as the prothorax, the joints of the funicle gradually widening outwards, 

 the antennal club pale and with the first joint broader than long, and the elytra clothed 

 with yellow scales and with a white spot at the apex of the suture. 



0. egregia, Fst., from Burma, is a much larger insect (6 mm.) with mottled 

 umber and ochraceous scaling on the elytra, and three transverse rows of pale spots 

 on the pronotum.
