FIVE NEW SPECIES OF NORTH AMERICAN ICHNEU- 

 MON-FLIES 



By Frank D. DeGant 

 Cleveland, Ohio 



The new species of ichneumon-flies described herein are from col- 

 lections made by the writer in the United States and Canada during 

 the summer of 1931. All type and allotype specimens are deposited 

 in the United States National Museum, as are also two paratypes of 

 Panaigyrops insula and two of Polysphincta venatrix. Two para- 

 types of Panargyrops insula are deposited in the Academy of Natu- 

 ral Sciences of Philadelphia. All other specimens are in the col- 

 lection of the writer. In describing the specimens a binocular micro- 

 scope with a total magnification of 102 X w^as used. 



The kindness of R. A. Cushman, of the United States Bureau 

 of Entomology, in comparing the specimens described with mate- 

 rial in the National Museum and in criticizing the manuscript, is 

 sincerely appreciated.
