Heterocera from the Australian Region. 423 



apex, its fourth running to the apex, fifth branch emitted from 

 near the base of the long footstalk, which bears the third and 

 fourth branches, just beyond the cell ; upper radial vein emitted 

 from the anterior angle, and lower radial from the posterior angle 

 of the cell ; disco-cellular veinlet angulated ; the three median 

 branches well separated from each other at their origins ; secondaries 

 with the costal margin nearly straight, outer margin slightly 

 arched, abdominal margin short and nearly straight ; costal and 

 subcostal veins contiguous to basal fourth, where they coalesce, 

 but separate again just before the middle of the wing, the costal vein 

 forming a long furca to apex and the subcostal continuing straight 

 on to the outer margin ; disco-cellular veinlet absent, the cell con- 

 sequently open, and the radial emitted as a fourth median branch ; 

 palpi moderately long, directed forwards so as to show almost their 

 entire length in front of the head ; antennae short, slender, monili- 

 form, finely penicillated ; thorax robust, projecting well in front of 

 the wings; tegulae large, extending to beyond the mesothorax; 

 legs thick (both legs and abdomen broken short off in the type). 



67. Niphadaza bicolor, n. s. 



Primaries above rust-red ; the base, an externally angulated band 

 across the basal third, a small spot near the base of the lower 

 radial interspace, a large apical costal spot, separated by a curved 

 stripe of the ground colour from an internally somewhat conical 

 external border (the centre of which is divided again by a forked 

 line of the ground colour) snow-white ; secondaries snow-white, 

 with a large subbasal interno-median spot, a broad discal band 

 with arched outer edge and a small oblique spot near the middle of 

 the outer margin, rust-red; antennae dark ferruginous banded with 

 white; body snow-white, collar with a ferruginous spot on each 

 side, thorax with darker red-brown scales at the sides ; primaries 

 below pale golden, with white markings almost as above ; 

 secondaries white, with a narrow diffused golden discal streak ; 

 body white. Expanse of wings, 24 mm.

OLIGOSTIGMA, Guenee. 

 68. Oligostigma pallida, n. s. 



Chalky white; primaries sparsely irrorated with dark brown 

 scales to external third, crossed at basal two-sevenths by an elbowed 

 pale ochreous band ; a second widely Insinuated ochreous band 

 crossing the wing obliquely beyond the middle ; a third band, twice 

 interrupted and with dusky zigzag external edge near to outer
