LBPIDOPTEEA OF THE FAMILY ZYGMNIDJ&. 403 



finding this species without a label, forthwith redescribes it. This 

 will, I think, account for several instances which I have noticed 

 of evidently the same species described twice over in consecu- 

 tive pages of Walker's Catalogues. 



Genus Coeematura, n. gen. 



Primaries with two subcostal and four apparent median branches 

 visible to the naked eye, the lower radial forming the fourth 

 median, the upper radial not visible ; discocellular strongly 

 angulated in the middle. Secondaries with two subcostal 

 branches, the upper one lying close to the costa, and four 

 median branches, the fourth being really the lower radial ; 

 discocellular strongly angulated. Antennae slender. Head 

 rather small. Abdomen very long, with large bushy anal tuft. 



Type C. chrysogastra, Perty. 



1. CoREMATURA CHRYSOGASTRA = Glaucopis chrysogastra, Perty, 



Delect, pi. 31. f. 10. 

 Eunomia abdominalis, Walker, Lep. Het. vii. p. 1617. 

 St. Paulo {Bates), Archidona (Stevens). B.M. 



Described again by Walker (in his ' Supplement,' i. p. 89) as 

 Lagaria abdominalis. 



Genus Argteoeides, n. gen.* 

 Primaries with one evident subcostal branch (forking from 

 below near apex) ; two radials placed at the upper and lower 

 extremities of the cell, so that the lower discocellular is re- 

 duced to about a quarter the length of the upper; discocellu- 

 lars nearly straight ; three median branches, emitted regularly 

 beyond the middle of the nervure. Secondaries with two sub- 

 costals ; one radial ; straight discocellulars, the upper rather 

 longer than the lower ; three median branches emitted regularly 

 beyond the middle of the nervure. Antennae plumose to near 

 the tip. Head moderately large ; palpi about level with top of 

 head. Abdomen constricted at the base, with terminal straight 

 anal tuft. Type A. opiiion, Walker. 



1. Argyroeides oPHioN = Glaucopis (Dinia) ophion, Walker, Lep. 



Het. i. p. 191. 

 Carthagena and Venezuela (Becker). Type, B.M. 



* I am aware of the fact that Argyrodes (sic) has been used for a genus of 

 Arachnida ; but I think Argyroeides distinct enough for so dissimilar a group of 

 animals.
