ICHNEUMON-FLIES OF AMERICA: 1. METOPIINAE 161 



tergites vestigial, of third and following tergites wide; seventh tergite 

 not retracted in either sex; female subgenital plate large, weakly 

 sclerotized, unspecialized. 



Four Nearctic species of Hypsicera are described here. Of these, 

 two are introduced species which occur around buildings. The other 

 two are native. The native ones are very scarce in collections. No 

 species of the genus, except for the cosmopolitan H. femoralis, and H. 

 curvator are known from the Neotropics. In contrast to the poor 

 representation in the New World, there are many species in the Old 

 World Tropics, all with the costula present and propodeal spiracle 

 elongate, thus showing relationship with H. femoralis. 



Key to the Nearctic species of Hypsicera 



1. Costula present and strong 2 



Costula completely absent 3 



2. Outer side of second lateral area of propodeura about 1.0 as long as inner side; 



propodeal spiracle long oval; first flagellar segment of female about 2.0 as 

 long as wide and about 1.8 as long a second segment (fig. 182,e); front wing 



3.8 to 5.0 mm. long; male scarce 1. femoralis (Fourcroy) 



Outer side of second lateral area of propodeum about 1.6 as long as inner side; 

 propodeal spiracle circular; first flagellar segment of female about 0.8 as long 

 as wide and about 0.9 as long as second segment (fig. 182, f); front wing 3.0 

 to 3.8 mm. long; male unknown 2. curvator (Fabricius) 



3. Head fulvous, the occiput brownish; front wing 3.7 mm. long. 



3. fulviceps, new species 

 Head black, the upper part of face pale; front wing 2.25 to 2.85 mm. long. 



4. cuncata, new species 



1. Hypsicera femoralis (Fourcroy)
