574 REVISION OF AUSTRALIAN LEPIDOPTERA, V., 



long pectinations in Ijotli sexes, apices simple. Tiiorax and 

 abdomen not crested. Thorax not hairj^ beneath. Posterior 

 tibife without middle spurs in botli sexes. Hindwings with a 

 strong rounded costal expansion at base, frenulum and retina- 

 culum obsolete in both sexes. Fore wings with 3 and 4 remote 

 at origin, 6 separate, II connected with 12 on a point only(four 

 specimens examined). Hindwings with 3 and 4 widely remote 

 at origin, 6 and 7 short-stalked or connate, 8 connected with cell 

 at a point near base, then diverging: discocellulars slightly angled 

 on vein 5, dorsal 'rather strongly oblique; costal edge of cell 

 considerably over §. 



Distinguished from the following genus by the absence of 

 tongue, and half-aborted palpi. It also differs in the neuration. 

 Type lodis qiiieta Luc. 



As Genochlora is one of the best genera that Mr. Warren has 

 characterised, it is surprising that he should have subsequently 

 (Nov. Zool. 1905, p. 422) merged it in the equally natural but 

 widely different Chlorochroma Gn. There are no less than six 

 points of difference between them, any one of which is sufficient 

 for generic separation. 



Genochlora Warr. — (1) Tongue absent. (2) Palpi half-aborted. 

 (3) Antennae with long pectinations in both sexes. (4) Frenulum 

 in (J absent. (5) Posterior tibiae without middle spurs in both 

 sexes. (6) Veins 3 and 4 of hindwings widely remote at origin. 



Chlorochroma Gn. — Tongue present. Palpi well-developed, 

 though short. Antennae in ^ simple. Frenulum in ^ present. 

 Middle spurs well developed. Veins 3 and 4 of hindwings closely- 

 approximated, connate, or stalked.

 Cilia wholly white, no discal dots 14. quantilla.
