other in length as in that genus. It is remarkable that Mr. Walker 

 should not have mentioned the very peculiar form of the fore-wings 

 in his description of this species. 



Type: Heptaloha argyriodactyla (figs. 1 and la). 



Platyptilus argyriodactylus, "Walker, Cat. Lep. Het., B. M., xxx, 

 p. 929 (1864). 



I would remark that the first plume of the hind- wings does not 

 "become wider from the base to the tip/' as asserted by Walker, and 

 there are more than one small squamous tuft on the posterior lobe of 

 the hind-wings. 



Cenoloba, gen. nov. 



Aniennce fortes ; palpi lahiales capite his longiores, maxillares de- 

 pressi ; alee anticw pcene ad inedium Jissce, angulo anali ohsoleto ; alee \ 

 posticce hilohatce vix ultra medium Jlsscd. 



Antennae stout, reaching to the cleft of the fore-wings, pubescent in the male. ! 



Maxillary palpi drooping. Labial palpi more than twice the length of the head, 

 haying the second joint slightly tufted beneath its apex, the apical joint short and 

 Bomewhat obtuse. 



Fore-wings cleft into two lobes nearly to the middle ; the anal angle of the pos- 

 terior lobe not defined. 



Hind-wings widely cleft to a little more than half their length into two lobes 

 only, the base of the cleft rounded ; costal margin of the anterior lobe slightly 

 raised towards the base. 



The posterior pair of legs are wanting in the type. 



The distinguishing peculiarity of this Australian genus is the 

 possession of only two lobes in the hind-wings. 



Type : Cenoloba oUiteralis (figs. 2 and 2a). \ 



Fterophorus obliteralis,'Wsi\keT, Cat. Lep. Het., B. M., xxx, p. 

 945 (1864). i 



To Mr. Walker's description I w^ould add — that there is a series 

 of about seven inconspicuous spots along the costal margin of the 

 fore-wings, and a conspicuous fawn-coloured spot at the base of the | 

 fissure in the hind-wings. j 



If this remarkably distinct genus is known to Mr. Meyrick, I ( 

 hope that his knowledge of other Australian PteropJioridce may enable i 

 him to assign to it its proper position in the Family. Its appearance ij 

 would place it near to the genus Aciptilia. The neuration is evidently 

 very simple, but I have been unable to examine it critically.
