THE NORTH AMERICAN NYMPHULINiE AND 

 SCOPARIIN^E. 



By Harrison G. Dyar, A.M., Ph.D.,

I have prepared the following account of the Nymphulinae 

 (Hydrocam'pinae) and Scopariinae at the instance of Professor C. H. 

 Fernald, who has loaned me his material in these groups. Professor 

 Fernald has undertaken a general account of the North American 

 Pyralidae (except the Crambinae and Phycitinae), but asked me to 

 relieve him of the work on the present groups. 



Family PYRALID.F. 



Subfamily Nymphulin^. 



Moths usually of very slender build, the legs very long. Proboscis present. 

 Fore wing with vein 7 from the cell, 10 usually stalked with 8 and 9, if not, the 

 maxillary palpi are long and dilated at the extremity. Hind wing with the median 

 nervure not pectinate. 



The group is close to the Pyraustinae, and not strongly distin- 

 guished therefrom. I am inclined to agree with Mr. Meyrick that 

 the group should be united with the Pyraustinae. I follow Sir 

 George Hampson in holding them separate for convenience sake, 

 though in the next catalogue I expect to see them united as they 

 were in Smith's 1891 list, where Professor Fernald followed Mr. Mey- 

 rick' s very sound views. 



To this group belong those peculiar larvae which are fitted for a 

 wholly aquatic life ; but not all the larvae of the group are so modi- 

 fied, so that the group is defined on no larval character. 



Taki.e of Genera. 

 Palpi upturned. 



Palpi with the third joint long and acuminate. 

 Maxillary palpi filiform, moderate.
