Walker considers that ' this genus belongs to the Torymida;, and is most nearly allied to Mcgastigmus,
Init it has also a tendency to the structure of the Leucospidai, and shews the transition between these two
faniilies '—a position I am not inclined to adopt, failing to obsei-vc any relationship with Leucospis.
The mandibles are strong and armed with three teeth, as in pi. XXV, fig. 10«, the inner part representing
the fourth tooth being broader and obtuse.
The IJntish Museum specimen has the terminal joints of the antcnnie broken off, the second joint of the
antenna; very small, and the third minute and annidar, the fourth and following much longer than the second,
and setose.
T regret that the rule of priority compels me to adopt the absurd names, both generic and specific, given
,to this insect by Mr. Walker.

I found a specimen of this interesting species lying dead and loose in a box of insects received from Assam,
sent me liy Major Jenkins. I had no means of determining whether it had been developed from any of the
insects, or had accidentally entered the box, or had fed upon some insect which might have attacked the wood
or eork of the box.

' Humerus extending at some distance from the costa; ulna about one-fifth of the length of the humerus ;
radius about twice the length of the ulna ; cubitus somewhat shorter than the ulna.'
Mr. Walker states that this ' very remarkable genus partakes of the characters of the Chalcidites and of
the Cynipites, and seems to differ from them both as much as they do from each other. It agrees with the
Chalcidites in the structure of the wing veins, and may be considered as tlic type of a new family of that
tribe.'
Except in having the abdomen compressed and the scutellum slightly bidentate (characters found in many
other Chalcididaj), I can perceive no relationship mt h the Cynipida;. The genus appears nearest related to the
Eurytomides.
