in H. pilosulus (Provancher) (fig. 54c). In H. parorgyiae (Viereck) 

 the region between the prelabial sclerite and the ventral part of the 

 labial sclerite has the form of a lightly sclerotized plate. In both 

 Horogenes and Hyposoter the labial sclerite has a small infolding at 

 each venterolateral edge. Olesieampe euurae (Ashmead) is very- 

 similar to 0. pikonemae Walley in structure. In 0. lophyri (Riley) the 

 labial sclerite differs in shape from that of these two species in that the 

 ventral part is broad ; also the prelabial sclerite is short and the mandi- 

 ble is distinctive in form, being relatively small with a rounded base 

 and a small, straight blade. Prochas theclae Walkley differs from other 

 Campoplegini in the length of the setae of the skin and the shape of 

 the mandible; however, the head sclerites in general resemble those 

 of the Campoplegini.

Tribe Cremastini 



Figures 57, 58 



Members of this tribe are endoparasitic, mostly in microlepidop- 

 terous larvae in leaf rolls and tunnels. Many of them frequent drier 

 habitats than is usual for the family. 



The tribe closely resembles the Campoplegini, although the head 

 sclerites are, in general, more lightly sclerotized. Also, the hypostomal 

 spur is longer, the lateral part of the stipital sclerite is not expanded, 

 except in Eiphosoma where the expansion is small, and the labial 

 sclerite is broader than in most Campoplegmi. In all species examined
