This genus is closely allied to both Lissopimpla, Kriech., and 

 Allotheronia, Ashm. (Proc. U.S. JSat. Mus. 1900, p. 55); but it 

 has neither the dentate femora and deeply impressed notauli of 

 the one, nor the " metathorax exareolated but with a strong 

 transverse apical area " and the basally entire median nervure of 

 the other, which is known only by a single MS. species from New 

 Zealand.
