136 Orper—HYMENOPTERA. 
Mr. Walker considers that ‘ this genus belongs to the Torymide, and is most nearly allied to Megastigmus, 
but it has also a tendency to the structure of the Leucospidw, and shews the transition between these two 
families ’"—a position I am not inclined to adopt, failing to observe any relationship with Leucospis. 
The mandibles are strong and armed with three teeth, as in pl. XXV, fig. 10a, the inner part representing 
the fourth tooth being broader and obtuse. 
The British Museum specimen has the terminal joints of the antenne broken off, the second joint of the 
antenne very small, and the third minute and annular, the fourth and following much longer than the second, 
and setose. 
I regret that the rule of priority compels me to adopt the absurd names, both generic and specific, given 
to this insect by Mr. Walker. 
Species 1—METAMORPHA LEUCOSPOIDES. 
(Walker, Op. cit. supra, p. 346.) 
Pratt XXV, Fie. 8. 
‘Fom. Nigra: caput antice flavum, nigro-vittatum, oculis flavo-submarginatis ; prothorax flavo-quadrimacu- 
latus; parapsides paraptera et scutellum flavo-marginata ; abdomen basi subtusque flavum; segmentis flavo- 
marginatis ; pedes lutei, coxis flavis nigro-variis, femoribus posticis nigris apice luteis ; tibiis tarsisque posticis 
flavis; ale lurido-cinerez, venis nigris.’ 
Length of the body, 5—6 lines; oviduct, 10 lines; expansion of the fore wings, 10 lines. 
Habitat ; Bootan (Pemberton), in Mus. Britann.; Assam, in Mus. Hopeiano Oxoniz (olim nostr.) 
I found a specimen of this interesting species lying dead and loose in a box of insects received from Assam, 
sent me by 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 cork of the box. 
Grenus—EUDOXINNA. 
(Walker, Trans. Ent. Soc. 3rd Ser. vol. ii. p. 206.) 
Fem. Corpus sat robustum ; caput et thorax punctata subpubescentia, caput brevissimum, verticale thoracis 
latitudine ; facies subdepressa, striata, striis versus os convergentibus (fig. 9a); mandibule faleate intus dente 
unico armate; palpi breves; antenn 9-articulate, filiformes, fronte insert; articulus primus subclavatus, 
subcompressus tubereulo parvo globoso subtus prope apicem instructus, secundus brevissimus, tertius et sequentes 
lineares subequales pubescentes parum attenuati, nonus apice conicus; prothorax transversus, lateribus rotun- 
datis; mesothorax brevis; parapsidum suture conspicue ; paraptera et epimera magna; scutellum vix biden- 
tatum; metathorax bene determinatus, fere verticalis; abdomen leve valde compressum (fig. 94), thorace non 
longius; segmenta antice contracta; pedes leves simplices breviusculi; femora clavata; tibia compresse, 
omnes presertim intermedie extus pone medium dilatatee ; ale antice late non longe. 
Syn.: Sosaetra. Walker olim, Trans. Ent. Soc. Lond. 3rd Ser. vol. i. p. 370. 
‘ 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; eubitus 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 
Chaleidites in the structure of the wing veins, and may be considered as the type of a new family of that 
tribe.’ 
Except in having the abdomen compressed and the scutellum slightly bidentate (characters found in many 
other Chalcidide), I can perceive no relationship with the Cynipide. The genus appears nearest related to the 
Eurytomides.
