NEW GENERA AND SPECIES OF ICHNEUMON-FLIES, 

 WITH TAXONOMIC NOTES 



3y R. A. CusHMAN 



This paper consists of the description of two new genera and 

 nine new species of ichneumon-flies, together with some notes on 

 synonymy, generic transfers, and the renaming of a genns the old 

 name of which is preoccupied. Also included is a key to the species 

 of the genus Cryptohelcostizus Cushman. The figures are from draw- 

 ings by Mrs. Mary Foley Benson. 



Genus POLYCYRTUS Spinola 



POLYCYRTUS BICOSTATUS, new species 



In my general key to the species of Pohjcyrtun ^ this species will 

 run best to e rythi'ostei'nus Cameron, but it has the propodeum of 

 entirely different form and differs by many other details of structure 

 and color. In my key to species examined (p. 2) it runs to the 

 second alternate of couplet 7 but differs from all the species falling 

 in that category in the form of the apical carina, which is broadly 

 transverse, instead of angulate, medially. 

 Female. — Length 11 mm., antenna 9 mm., ovipositor sheath 3,5 nnn. 

 Vertex in front view flat and at the same level as upper eye mar- 

 gins; frons polished, scrobes moderately deep, horn very short conical, 

 without basal pits or tubercle ; eyes parallel within, comprising nearly 

 two-thirds total width of head; inner orbits very finelj^ shagreened
