 Mali:. — Uijjjerslde : forewings liUu-k, with an intense and brilliant blue gloss 

 in side light, washed over with a glittering metallic- fiery sheen. A little away from 

 the base there is a band of lavender-blue. 6 millimetres wide at the costal and 

 4 at the inner margin. Hindwings same colour, but without markings. 



Underside : forewings as above, but bar wanting, and three small spots of ])ale 

 blue, one in apex of cell, the two others bordering ai)ex of cell. 



Palpi black with a white side line; head black with white border to eye. Hairs 

 of coxae and femora ochraceous ; rest of body black with a blue gloss.

Hi. Burgena amoeua Kothsch. sp. nov. 



Fem.\le. — Upperside : forewings similar to B. chalybeata, mihi, but the metallic 

 sheen more green and less fiery ; a pale blue spot beyond the centre of cell ; a 

 discal bandiike patch crosses the wings between the subcostal vein and the inner 

 margin, ■! millimetres wide in centre, which is white, while at each end the band is 

 pale blue. Hindwings unicolorous, deep greenish blue, as in chalybeata. 



Underside as above, but the gloss is much less strong and the spot in cell is not 

 lound but linear, and the bandlike patch is of uniform width, wliile above it is 

 much constricted towards the subcostal vein. 



Paljii, head, thorax, legs, and abdomen as in chalybeata, as is expanse. 



Hah. Kinnigunang, New Britain (Ribbe) ; 1 ? . 



I have described this species as distinct from chalybeata, because in the genus 

 liitrtjeaa no case of sexual dichromism is known ; and certainly there is in the family 

 Aijaristidae no such extreme case as this would be. ^^'. i\. 



Cruria Jord. gen. nov. 



d ? . Forehead with a conical processus bearing a strong circular riilge. Antennae 

 slender, very feebly thickened between middle and tip, scarcely longer than half the 

 length of the forewing. Terminal joint of palpi naked, at least four times as long as 

 broad; rest of palpi hairy, but hairs not longer than third joint. Legs very slender, 

 tibiae naked. 



Neuration : forewings with \ein lU nearer to 9 than to the areole ; vein :j from 

 below apex of cell, 4 nearer to 5 than to 3 ; second partition of median uervure longer 

 than the respective portion of the outer margin. Hindwings with both discocellulars 

 oblique; vein 3 distinctly from before angle of cell: second i)artition of median 

 uervirre of the length of the lower discocellular veinlet. 



Type: Cruria donmvani (Boisd.), Voy. Ai<trolal)e, Lep. p. 17(>. u. 7 (1832) 

 (Australia). 



Easily distinguished from Phalaenoides Lewin liy vein 1(» of the forewings 

 being stalked with 8 and d. The females are generally <larker than the viales in this 

 genus, and seldom have the costal margin of tin- forewings ochreous, as it is in the 

 males.
