732 Hymenoptera in America North of Mexico 



Type-species: Catastenus femoralis Foerster. Monotypically included and desig. by 

 Foerster, 1871. 



Townes (1971) indicated that Catastenus could be regarded as an aberrant section (a species 

 group?) of Syyuplecis; he maintained its generic status pending further development of the clas- 

 sification of the subfamily. 



This is a small Holarctic and Ethiopian genus. Townes and Townes (1951) said that 

 "undescribed Nearctic species of this genus are transcontinental in the Transitional Zone." How- 

 ever, Townes (1971) said that it is an unresolved question whether there are in the Holarctic Re- 

 gion a number of closely related species or just a single variable one.

Holomeristus Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 171. 



Type-species: Holomeristus tenuicinctus Foerster. Monotypically included and 

 desig. by Foerster, 1871.

 species included by Foerster, 1871. 

 Trestis Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 174. 



Type-species: Trestis tricincta Ashmead. By subsequent monotypy from inclusion 

 by Ashmead, 1902. 

 Ischyracis Foerster, 1868. Naturh. Ver. Rheinlande, Verh. 25: 175. Apparently, Horstmann
