Front wing 3.6 to 8.7 mm. long; hairs of head and body excep- 

 tionally dense; thorax of moderate proportions or rather elongate; 

 frons unarmed; clypeus of moderate size, strongly convex, its apical 

 margin broadly truncate or weakly concave; mesoscutum moderately 

 long and convex, subpolished but with very fine, dense, setiferous 

 punctures; notaulus long, strong, deeply impressed, surpassing center 

 of mesoscutum; epomia absent or short and weak; prepectal carina 

 ending a little above center of hind margin of pronotum; posterior 

 mesosternal carina usually interrupted in front of each middle coxa 

 but in the species scotina complete; propodeum more or less elongate 

 and with more or less distinct dorsal and posterior faces; transverse, 

 lateral longitudinal, and median longitudinal carinae of propodeum 

 distinct and more or less complete, the basal transverse carina ob- 

 solescent in the species sericata; sublateral crests of apical transverse 

 carina of propodeum strong; areola defined by carinae laterally; pro- 

 podeal spiracle subcircular to elongate; areolet pentagonal or sub- 

 rectangular, the width of its front side variable; ramellus short or 

 absent; nervulus at or a little basad of basal vein; nervellus broken 

 below, at, or a little above the middle; axillus near anal margin; first 

 abdominal segment rather short and stout, without a basolateral 

 tooth, rather gradually expanded apically, its spiracle somewhat be- 

 yond the middle, its dorsolateral and ventrolateral carinae strong 

 and complete, its median dorsal carinae strong to distad of its spi- 

 racle; second tergite subpolished, with dense or very dense, usually 

 rather weak punctures; tergite 7 often marked with white; ovipositor 

 sheath about 0.4 as long as front wing; ovipositor compressed, the 

 teeth on its ventral valve only a little oblique, its upper valve some- 

 times serrate between nodus and apex.
