Meg'acephala. 



Harpe deeply emarginate on the outer edge of the 

 cucullus, forming a strong curved hook ; clasper a single 

 curved arm ; uncus simple ; the vesica has a large 

 bunch of long and short cornuti. 



Ligustrl. 



Harpe rounded, quite simple, with a fold arising from the 

 sacculus ; there are no claspers; uncus cygnated, with 

 a long scaphium ; vesica has a mass of small cornuti. 



The Genus Leucania is a most unnatural sequence 

 to the A crony etas. After throwing out hrevilinea, which 

 evidently belongs more to the Hydroecias, the Leucanias 

 separate naturally into two distinct divisions ; those with 

 the rounded battledore harpes, and strong corona ; and 

 those in which the harpes are not battledore, and only 

 have marginal spines- Of the first division we may take 

 turca as a type, we have in order pallens, failcolor, 

 lithargyria, littoralis, viteUina, pudorina, albipiincta, and 

 L-album. Conigera, impura, and straminea are separated 

 from the foregoing by the pointed apex of the harpe, 

 whilst extranea takes the most exaggerated form, the 

 pointed apex forming a strong spine, whilst the lower 

 portion of the harpe bulges out enormously. 



The second group is composed oi putrescens, comma, 

 and obsoleta, keeping flammea, which appears to closely 

 follow this second group, in its separate genus Meliana. 



TuPCa. From S. J. Capper. 

 Harpe battledore, several rows of spines on the cucullus ; 

 clasper. long ; ampulla sickle shaped ; uncus tongue 

 shaped ; the vesica has long band of short teeth. 



Pallens. 



Harpe battledore, with spinose cucullus ; clasper with 

 elbowed arm ; ampulla curved ; uncus cygnated ; vesica 

 with long band of short teeth ending in a mass of larger 

 ones.
