Author leg. - O. udeana is considered by me to be the same species as wallacei, from Borneo and the Malay Peninsula. The two males, now before me, are of different size and in one of them the body-colouring is much faded; in fact, the colours of this fine insect rapidly disappear in dried specimens, They do not differ from a small series of Kuala Kangsar, Perak, in the Hamburg Museum. Fraser's key to the Malaysian species and re-description of O. udeana are entirely misleading and partially copied from Ris's description of immature specimens. I believe, that Kruger's species is correctly referred here and that the differences noticed between wallacei and udeana are due to the effects of decomposition. A colour-description of the living insect, and sketches of genital organs will be published elsewhere. The male, captured by myself, was resting with its wings half open.
