Gen. 26. H e t e r o p t i l a, n.^. 

 ere/DOTTTtAos, with dissimilar wings. 



Frons ruunded, somewhat projecting. Tongue well-developed. 

 Palpi moderate, porrect ; second joint densely hairy beneath ; 

 terminal joint \ ery short. Antennae of g shortly bipectinate, 

 tow^ards apex simple. Thorax with a dense, bifid, posterior 

 crest, beneath hairy. Femora glabrous: posterior tibiae of (J 

 dilated. Forewings with 10 and 11 separate and free, or anas- 

 tomosing with each other, and then 10 with 9. Hind wings 

 normal. Type, Sdidosema argoplaca Meyr. 



An endemic derivative of Cleora, distinguished by the strong, 

 thoracic crest. From Symmetroctena, it differs in the separate 

 origin of veins 1 and 11. It is remarkable that, while the 

 fovea is large and well-developed in H. argoplaca, it is obsolete 

 in the closely allied H. xylina. In three males of the latter, I 

 can distinguish a shallow fovea on one side in one example only; 

 but, on the other hand, the posterior tibiae are abnormally dilated 

 so as to be almost club-shaped. The usual neuration of H. xylina 

 is very exceptional. 



1. Underside of fore- and hind wings with an apical, whitish spot argoplaca. 

 Underside of fore- and hindwings without an apical, whitish 



spot xylina. 



95. Heteroptila argoplaca. 



Selidoseyna argoplaca Meyr., Proc. Linn. JSoc. N. S. Wales, 

 1891, p.615. 



Antennal pectinations of $ 2i, apical f simple. Forewings 

 with 10 and 11 separate, not anastomosing (5(J, 49); 10 fre- 

 (juently runs very close to 9, and, according to Mr. Meyrick, the 

 two may be connected.

(J9. 32-38 mm. Head fuscous. Palpi fuscous mixed with
