Subfamily BANCHINAE 



The distribution of this large subfamily is worldwide. The species are all thought to be inter- 

 nal larval parasites of Lepidoptera. 



Tribe STILBOPINI 



This small tribe includes three genera, only one of which is known from the Nearctic region. 



Genus STILBOPS Foerster 



Stilbops Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 163. 



Type-species: Pivipla vetula Gravenhorst. Desig. by Ashmead, 1900 from two 

 species included by Schmiedeknecht, 1888. 

 Apkanoroptruvi Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 168. 



Type-species: Lisso7iota nificoniis Gravenhorst. By subsequent monotypy from 

 inclusion by Thomson, 1877. The type-species is regarded as a synonym of S. 

 abdovtinalis (Gravenhorst).

Type-species: Eritrachynus asper Schmiedeknecht. By subsequent monotypy from 

 inclusion by Schmiedeknecht, 1913 (fasc. 25, p. 2724). 



According to Townes (1970) this is a moderate sized genus of Holarctic and Oriental distribu- 

 tion. An undescribed species is known from Maryland. The European S. abdominalis 

 (Gravenhorst) has been reared from the incurvarioid lepidopteran Adela reamurella (L.); its life 

 cycle is apparently analogous to that of pionine Ctenopelmatinae, the egg being deposited inside 

 that of the host and the adult emerging from the host after the latter has spun its cocoon.

Tribe GLYPTINI 

 Ten genera are known. Three occur in the Nearctic region.

Genus SPHELODON Townes

Type-species: Glypta phoxopteridis Weed. Orig. desig. 



Only three species have been described, but according to Townes this is a moderately large 

 genus. It is principally Neotropic, but two species are Nearctic.
