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

 legs, but differs in tlie fore wings wanting the areolet," whic-h 

 feature must ])rechide it from the Banciiiues. Dalla Torre was 

 so mucli at a kiss concerning its affinities that lie phaces it among 

 his very few " genera Ichneumonidarum sedis incertie," 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 TRYruoNiN.E, wherein the normal face and 

 scutehum, bidentate mandibles, and lack of areolet preclude its 

 j)ositi©n in any group but the TuYrnoNiDES. The pale-banded 

 antennae remind one of Eitri/proctus, and it is its lack of distinctive 

 features, not of abnormality, which renders it dilHcult to placi'. 

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

 tion of the type inclines me to consider it allied to hAnjalta, thongli 

 our ignorance of the female renders such a position at present 

 undesirable.
