MOTHS OF THE GENUS CINCIA AND THREE NEW AND 

 CLOSELY RELATED GENERA 



By William D, Field 



The genera of moths treated herein (family Arctiidae: subfamily 

 Lithosiinae) are indigenous and restricted to Jamaica, Until the 

 present time they have been treated as a single genus with two species, 

 Cincia pallida Butler and C. conspersa Walker. A careful study of 

 200 specunens from the collections of the United States National 

 Museum, the British Museum of Natural History, the American Mu- 

 seum of Natural History, and the Carnegie Museum disclosed four 

 genera and ten species involved in the complex. 



Venational characters are much the same in the four closely related 

 genera. In order to avoid repetition in the generic descriptions these 

 common characters are given here : Venation of forewing with vein 2 

 from past middle of cell and from outer third or before; vein 3 from 

 just before lower angle of cell; 4 and 5 separate or extremely short 

 stalked or connate from lower angle of cell; 6 from below upper angle; 

 7 from stalk of 8 and 9; 10 and 11 free; 10 from middle or nearer stem 

 7, 8, and 9 than 11 ; 11 from beyond middle of cell and curved toward 

 12, distally coincident with 12. Venation of hind wing with vein 2 

 from outer third of cell or beyond; 3 stalked with 4 from lower angle 

 of cell or sometimes connate with 4 and 5 and rarely separate from 4 

 and 5; 5 absent or present and stalked with 4; 6 and 7 stalked from 

 upper angle of cell; 8 from before middle of cell.
