Tribe APTESINI 



In transferring the genus Echtlirus to the group he formerly called the Hemigastrini, Townes 

 (1970) changed the name of the group to Echthrini because of his preference to base super- 

 generic group names upon the oldest included genus rather than upon the oldest supergeneric 

 name; following the latter practice would have resulted in his retention of the name Hemigas- 

 trini. Because of my belief that Hetnigaster actually belongs in the group Townes (1970) called 

 the subtribe Baryceratina (tribe Cryptini), the name Hemigastrina is here applied to that sub- 

 tribe. 



Most Aptesini oviposit into the cocoons of sawflies, but the species of Echthrus and 

 Demopheles parasitize wood boring Coleoptera, and Polytribax parasitizes Lepidoptera.

Genus DEMOPHELES Foerster 



Demopheles Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 186. 



Type-species: Phygadeuon caliginosus in the sense of Thomson (1873). By 

 subsequent monotypy from inclusion by Ashmead, 1900. Ashmead (1900) 

 suppressed the monotypic genus Mecocryptns as a synonym of Demopheles, 

 thereby including the type-species of Mecocryptns (which see) in Demopheles (cf. 

 Perkins, 1962). 



Mecocryptns Thomson, 1873. Opusc. Ent. 5: 520, 521. 



Type-species: Phygadenon caliginosus Gravenhorst, not as restricted by 



Taschenberg and Frilli. Monotypic and orig. desig. Thomson did not say that he 

 was applying the name caliginosus to Gravenhorst's female, but this is implied by 

 the fact that on the same two pages he described a new genus and species, 

 Stenocryptus nigriventris, for what he believed to be Phygadeuon caliginosus
