DESCRIPTIONS OF HY3IEN0PTERA FROM SPITZBERGEN, 

 COLLECTED BY THE REV. A. E. EATON. 



BY THE REV. T. A. MARSHALL, M.A., F.L.S. 



The following five species (of wliicli four are new) were described 

 by me some time ago, at the request of the captor ; but the descrip- 

 tions having been mislaid by him, it has become necessary to repeat 

 them. They ai'e written so as to be in conformity with Holmgren's 

 Monographs. The insects are not remarkable, except as being a sample 

 of the Arctic Fauna, and containing among them a form of Orthocen- 

 trus with the wings imperfectly developed.
