at tlie ends of the nervures, and two orange spots near the 

 margin, as on the upperside ; anterior margin and nervures 

 narrowly black. Head, thorax, and antennae black. Abdo- 

 men ochraceous, a row of spots on each side. Expanse of 

 wings 6i inches. 



Two males of this extraordinary and gorgeous insect have 

 recently been sent to England by Mr. Woodford, who cap- 

 tured them in the island of Malayta, one of the Salomon 

 Islands, with several females, flying at the tops of trees, where 

 he was obliged to shoot them. A specimen of the female has 

 been in the British Museum for upwards of thirty years and is 

 described and the upperside figured in the * Proceedings of 

 the Zoological JSociety,' 1856. 



In the collection of Mr. H. Grose Smith.

The male of this species resembles 0. gazella^ Fabr. {hi- 

 color of many authors) ; but, besides the red colouring of the 

 underside, it differs in having the mandibles straighter, less 

 flat, and less rugose. The head is shorter and broader. The 

 thorax is rather flatter and more parallel, i. e. the lateral 

 angle is not so prominent. The anterior tibiae have two 

 small teeth on the posterior edge ; the other tibise are un- 

 armed.
