Broken Hill, N.S.W. ; ten specimens during October and 

 November. 



A very variable species; the description is drawn from a well 

 marked specimen; in some specimens the markings are scarcely 

 traceable owing to the groundcolour. The species, when at rest, 

 is an admirable imitation of birds' droppings. 



SCIEROPEPLA MEGADELPHA, n.sp. 



(J 5. 18-24 mm. Head and thorax shining snow-white. 

 AntennfB and palpi fuscous, palpi internally and base of second 

 joint whitish. Anterior and middle legs fuscous; coxse shining 

 snow-white; posterior legs whitish. Abdomen yellowish. Fore- 

 wings elongate, moderate, costa gently arched, apex round-pointed, 

 hindmargin very obliquely rounded, 7 and 8 long-stalked, 7 to 

 costa; shining snow-white; a tine fuscous line along costa from 

 middle to apex, attenuated anteriorly; a moderate fuscous streak 

 along inner margin, from near base to hindmargin, posteriorly 

 attenuated : cilia shining snow-white. Hindwings pale whitish- 

 ochreous; cilia as in forewings. 



Broken Hill, N.S.W.; twelve specimens, mostly taken at electric 

 light, from August to November. 



This species furnishes another instance of remarkable mimicry; 

 in general appearance it resembles Chalarotona craxpedota, Mej'r., 

 so closely that one could easily be persuaded into considering it 

 that species, but the neuration affords a safe distinguishing test. 

 I have examined no fewer than nine specimens, in which each 

 and every one was structurally identical with the genus Sciero- 

 pejjla, Meyr. A species named by Dr. Turner (Annals Queenx- 

 land Museum, No. 4, 1897) as Lichenaula dissiniilis must be 

 (according to description) very similar in appearance, but the 

 termination of vein 7, which is hindmarginal, and the larger 

 size should be sufficient characters to distinguish it from the two 

 species previously mentioned. 



Procometis heterogama, n.sp. 



^. 20 mm. : 9- 30-32 mm. Head in ^ whitish, in J fuscous. 

 Thorax fuscous, patagia whitish. Antennae white, annulated
