This is a very common and variable species, some of 

 the forms of which bear a considerable resemblance to 

 Euplexia sepultrix. 



The Euplexia pectinata of Warren, which closely re- 

 sembles E. albovittata, Moore, belongs to this genus. 



HABEYNTIS, Led. 



H. v-brunneum, Grote, appears to me to be nothing 

 more than a variety of H. periculosa, in which the 

 central belt of the primaries is blacker.

CEL^NA, Steph. 



I cannot see any reason for distinguishing Hydroscia 

 and Helotropha from this " genus." Celcena is very 

 close to Mamestra, so much so that I find that M. stricta 

 (= cinnabarina) and M. olivacea (which looks like a 

 black form of the same thing) undoubtedly belong to 

 Celcena, and are closely allied to C. renigera; on the 

 other hand, M. egens, which I considered (Trans. Ent. 

 Soc., 1889, p. 386, n. 7) to be identical with M. stricta, 

 proves, upon a second examination by a better light, to 

 be nearer to M. strigiiis : Walker's type is much worn 

 and rubbed, so that one might be excused for making it 

 synonymous with almost any species of the same size ; 

 nevertheless, traces of the pattern can be seen with the 

 help of a lens and bright sunlight. 



Celana appears to be a fairly natural group, but the 

 structural distinctions between it and Mamestra are not 

 apparent on the surface.
