^afe.— West Virginia, (Coll. Am. Ent. Soc, and Mr. E. Norton). 

 Five % specimens. This handsome species is easily recognized by 

 the narrow form, allied to that of /nsa'pcnnis, by the long and ample 

 hyaline wings, broadly tipped with fuliginous, by the subpetiolate ab- 

 domen and by the annulated tarsi. It may be the % oi fuscipennis.
