Hydrusa ecliptis, Meyr. PL v., fig. 11. 

 Brisbane. One specimen taken by Mr. Illidge. This exactly 

 corresponds with the types in the Macleay collection, which are 

 from Cooktown. 



Hydrusa lampetis, n. sp. PI. v., fig. 12. 



Female, 35 mm. Head and face reddish-orange, with a broad 

 black line between antennae. Antennae black to apex. Thorax 

 wlioUy black. Abdomen orange, bases of segments black ; two 

 terminal segments wholly black, except anal hairs ; beneath 

 wholly black. Forewings dull-blackish fuscous, with a brilliant 

 purple lustre in oblique light ; spots small, pale-dull-orange, 

 reddish-tinged, semi-transparent ; first coalescing with third to 

 form an elongated oblong spot of moderate size ; second small, 

 wedge-shaped ; fourth elongate, connected with fifth by an 

 equally large additional spot ; fifth bisected unequally, upper seg- 

 ment elongated, lower sub-triangular. Hindwings dull-blackish 

 fuscous with purple lustre ; spots pale-orange, semi-transparent ; 

 basal spot small, bisecting vein not black ; second very small, 

 triangular, touching first. 



It is possible that this may be an extreme variety of H. 

 ecliptis. The present species is distinguished by the much smaller 

 spots and by the distal spot of hindwing not being completely 

 merged with basal spot. 



Bowen, Queensland ; one specimen (Coll. Queensland Museum). 



Hydrusa sphenophora, n. sp. 



Male and female, 31-36 mm. Headand face orange, with a narrow 

 black line between antennae. Antennae black to apex. Thorax 

 black, with a conspicuous posterior orange spot. Abdomen 

 orange, base of segments narrowly fuscous above, more markedly 

 so beneath, apical segment blackish-fuscous, tuft orange. Fore- 

 wings black with greenish-iridescence, spots moderate or rather 

 large, pale-dull-orange, opaque ; first subquadrate, broadly 

 separate from third ; second wedge-shaped, apex anterior, obtuse; 

 third irregular oblong, prolonged upwards anteriorly, where it is 

 separated from second only by vein ; fourth connected by an 

 additional spot with fifth, the whole forming a broad wedge with 

 apex downwards, separated by veins into four segments, decreas- 

 ing in size from above downwards, upper three elongate, lowest 

 triangular. Hindwings with spots same colour as forewings, 

 large and confluent ; leaving an irregular black line along hind- 

 margin, thickest at apex, toothed below middle ; and a black 

 spot below middle of costa. 



Allied to H. ecliptis and H. stelotis. From the former distin- 

 guished by separation of first and third spots, from the latter by
