NOTES ON THE SYNONYMY OF NOCTUID MOTHS. 121 



United States, Georgia, Texas. In Coll. B. M. 



Walker identified certain examples of this species with 

 Guenee's PoapMla hcrharum, and the specimens which he 

 recognized as P. vinculum are probably faded examples of 

 P. sylvarum. The two supposed species P. vinculum and P. lima 

 differ less than the sexes ; P. lima is a male form, in which the 

 outer transverse stripe is more than usually sinuous, and both 

 stripes have more than usually dark diffused external borders.

Poaphila herharum, Guenee, Noct. 3, p. 303, n. 1757 (1852). 



United States. Female in Coll. B. M. 



Guenee says of his P. herharum that it is very close to 

 histrigata, but it is larger, less brightly coloured, and has the 

 second line regularly arched instead of slightly sinuous. It is 

 characteristic of the species that the yellow border to the second 

 line is outside instead of inside it. Guenee's distinctions are 

 trivial and valueless. Walker identified specimens of Phurijs 

 immunis as Poaphila histrigata. 



FoDiNA, Guen., and Colbusa, Walk. 

 These two genera are so similar in colouring, pattern, and 

 form, that they have been confounded in collections. Foclina has 

 long upcurved palpi, and will include the following species : — 



F. oriolus, pallula, and stola, Athyrma alhicincta, Walk., F. sar- 

 mentosa, ostorius, and euclidicola, with their allies, and Trigonodes 

 cuneigera, Butl. 



Colhusa will take C. euclidica, Grammodes conjungens, 



G. mygdon, G. delta, and their allies. In this genus the third 

 joint of the palpi is very short. 



I think it very doubtful whether Sarrothroceras, Mabille, can 

 be structurally distinguished from Foclina ; but, at present, we 

 only have the female of his typical species. 



The genus Ccdyptis should, in my judgment, stand next to 

 Colhusa (it is certainly not a Plusiid), and should be followed by 

 Cahralia, Moore. 



Phurys hiangulata and Trigonodes ohstans may be placed 

 under Tleteropygas, Guen., to which genus I think Pelamia must 

 be allied ; but I only know the latter from Guenee's figure.
