shown by their agreement in the form of the head, thorax, and 

 legs, but differs in the fore wings wanting the areolet," whirh 

 feature must preclude it from the BANCHIDES. Dalla Torre was 

 so much at a loss concerning its affinities that he places it among 

 his very few " genera Ichneumonidarum sedis incertse," though 

 the lack of areolet, slender basal segment and subcentral petiolar 

 spiracles appear to leave but little doubt respecting its right to 

 inclusion in the TRYPUONIX.E, wherein the normal face and 

 scutellum, bidentate mandibles, and lack of areolet preclude its 

 position in any group but the TKYPHONIDES. The pale-banded 

 antennae remind one of Euryproctus, and it is its lack of distinctive 

 features, not of abnormality, which renders it difficult to placn. 

 I do not for a moment anticipate stability for it, and an examina- 

 tion of the type inclines me to consider it allied to Eugalta, though 

 our ignorance of the female renders such a position at present 

 undesirable.
