shown in the figure, given by Na vas, are the two latera 1 

 edges of the triangulär elevation. These lateral edges are 

 sometimes faintly brownish coloured. In »The Entom. Monthly 

 Mag.», Vol. 24, p. 44 Mac Lachlan, who has seen the type 

 specimen of Walker, pointed out that stictoneura was syno- 

 nymous vvith insignis. 



Nothochrysa punctistigma n. sp. (pl. 2, fig. 7). — Head 

 and body påle brownish yellow. Head without markings. 

 On the vertex a sharply defined triangulär elevation. (In the 

 centre of the triangulär elevation an indistinct brownish spöt 

 is visible, but I think the spöt is wanting when the inseet 

 is alive.) Antennae almost as long as the forewing, yellowish 

 and without annulations; basal joint very stout. Eyes bronze- 

 green. Prothorax about twice as broad as long; front angles 

 truncate. A median longitudinal furrow is visible. A trans- 

 verse furrow one third from the hind margin; the furrow 

 does not reach the lateral margins. A spöt close to the front 

 angle and a streak from the end of the transverse furrow 

 towards the hind margin are indicated. Two träns versely 

 placed spöts are indicated on the front margin of the meso- 

 thorax. Above the base of each wing an oblique dark brown 

 streak. Legs yellowish. Membrane of wings hyaline. Longi- 

 tudinal nervures yellowish. In the forewing Rs, pseudo- 

 media and pseudo-cubitus are blackish annulated. where they 

 are touched by the blackish crossveins. Most crossveins in 

 the forewing are totally blackish; but in the hindwing and 

 in the costal area of the forewing they are only blackish at 

 each end. A few crossveins at base of forewing blackish 

 shaded. Pterostigma greyish yellow. At the inner end of 

 pterostigma a small, but very conspicuous, dark brown, or 

 when the wings are held in a certain direction, reddish (san- 

 guineous) brown spöt is found, enclosing a crossvein between 

 8c and R. 



Length of forewing 15 mm; that of hindwing 13 mm. 



One male specimen from Broome, N. W. Australia, Oc- 

 tober. 



The species is similar to N. insignis; but it is smaller. I 

 think, however, that the peculiar marked pterostigma may 

 easily separate it from the other Australian species. 



The specimen before me seems to be somewhat imma-
