 Ent. Soc, xxxix.. 1913, p. 204. 



There is a single male of this very beautiful species in my collection, taken 

 at Cradle Mountain. This lia.s been compared with Banks' type. The short de- 

 scription given by Banks may now be supplemented as follows : — 



c?, exjianse 43 mm. C<erci 14 mm. long, dark brown, strongly ciliated, with 

 basal joints very short, much wider than long. Superior appendages very short, 

 acutely pointed. Forewings purplish, with pale reticulation weakly developed on 

 the anal area and on the cross-veins beyond the lunule. Subhumeral oval mark 

 veiy distinct, pale yellowish. No red radial stripe present. Tjunule wliitish 

 tinged with purple, veiy clearly defined, about 2.8 mm. wide, nearly reaching the 

 costa, and ending posteriorly on the wing border 2 mm. wide. Hindwings with 

 the basal part orange red, this colour extending to about half way on the costa, 

 but much less in other directions; by far the greater area of the wing is a beauti- 

 ful purple. The division lietween red and purple is strongly dyslegnic, the purple 

 encroaching irregularly on the red.

EuSTHENlOPSis VENOSA, n.sp. (Plate xiv.. Fig. 7.) 



?, expanse 40 mm. Pronotum dark grey, bordei'od in front and behind with 

 brown. Fore femora with a i)ale yellowish ring apically. Forewings dark brown, 

 with very strong and distinct pale reticulation of all the main veins and cross- 

 veins; a small amount of similar reticulation is also to be seen near the apex of 

 the hindwing. In the forewing, the costal veinlets number about twenty. Sub- 

 humeral mark jiresent, whitish; another small squarish blotch of the same colour 

 covers M.-,. No red radial stripe present. Lunule exceedingly narrow (little over 

 1 mm. wide in middle), and with both borders irregiilar; it reaches from Sc to 

 the posterior margin of the wing. Hindwings with the basal three-fifths purple, 

 tlie area occupied by this colour being s(]uarish. strongly angulated on the vena 

 dividens. and with its border somewhat concave above this angle. Best of hind- 

 wing dull greyish-black, the division between purple and black eulegnic.
