and two have 7) ; in the six hind-wings, four have 6 postnodals and two have 7 ; 

 one regular cubito-anal cross-vein only in each wing, placed at or proximal to the level 

 of the first antenodal (in 0. dohrni there is usually another, placed beyond it, in the 

 hind-wing) ; the second cubito-anal cross-vein in the fore-wing, forming the basal side 

 of the subtriangle, is placed more obliquely, thus appearing less like a continuation 

 of vein A ; Rspl. well defined in all the wings (barely recognisable in 0. dohrni). 



Legs long and slender ; the coxte and trochanters of all the legs yellow ; femora 

 brownish-black externally, yellowish-brown internally ; tibise for the most part yellow ; 

 tarsi blackish. Femur of hind-legs with an external row of about 20 very short 

 spines and a few long hairs projecting beyond them, terminating at the distal end in a 

 long spine ; an internal row of about 12 long straight hairs ; femur of mid-legs with 

 an external row of about 8-10 long slender spines, increasing in length progressively 

 from the base of the femur to the apex ; an internal row of about 20 long slender 

 hairs ; tibial spines numerous, long, and slender ; tarsal claw-teeth small, at about two- 

 thirds the length of the claw. Abdomen not constricted after the third segment, 

 as it is in 0. dohrni. Genitalia of segment 2 crushed and not well-displayed ; 

 anterior lamina clothed with long hairs, about as broad as long, parallel-sided, 

 and with the apical margin rounded ; the hamules twisted out of their natural 

 position ; viewed laterally the anterior branch appears as a long, stout, slightly- 

 curved lobe, ending in a rather sharp point and touching the genital lobe ; posterior 

 branch, concealed in lateral view, short, curving towards the anterior branch, and 

 apparently very slender ; genital lobe erect, and rather long and narrow. Segment 1 

 yellow, with the basal half of the dorsum black ; 2 black with a little yellow at the 

 sides, basaily ; 3 and 4 black, without visible markings ; 5 and 6 black, with a large 

 yellow spot on each side ; 7 yellow, with a black ring at the base and another at the 

 apex ; 8, 9, and 10 black. Upper anal appendages black, about as long as segments 

 9 and. 10 taken together, curving downwards and becoming stouter for the greater 

 portion of their length, and then giving rise suddenly to a sharp spine directed 

 backwards ; lower appendage yellowish, shorter than the upper appendages, concave 

 above, broad basaily, heart-shaped.

d . Wings purple-blue, without apical spots. I have compared the male example 

 with a somewhat larger male from New Guinea in the British Museum (Stephansort, 

 Astrolabe Bay, Biro). In the Stephansort specimen the large basal coloured area 

 approaches nearer to the pterostigma in all the wings by about 2 cells, but the milky
