1CHNEUMONIN.E IN THE BRITISH MUSEUM. 145 



that the original account of the genus will have to be sufficiently 

 modified to embrace the following additional African kinds, which 

 I have compared with the types of both Cameron's species. He 

 himself, while placing it in the Joppides, was doubtful of its 

 position and remarks that it " does not fit well into any of 

 Kviechbaumer's groups of the Hemijoppinae " ; as a matter of 

 fact, the total lack of basal metanotal sulcus in the genotypical 

 specimen, with its very fiat scutellum, places it (I consider, 

 certainly) in the Ichneumonides. Of palsearctic groups, it is 

 most closely allied to Melanichneimion and especially Eupalamus.

 punctate, the latter hardly discreted, apically truncate, laterally 

 rounded and elevated; mandibles stout and sparsely punctate, with 

 teeth black. Antennfe subfiliform ; of $ very slightly dilated 

 beyond centre, with the 10th to 18th flagellar joints white ; of S 

 subseri-ate, with the 19th to 25th flagellar joints white. Thorax 

 very stout and black with prothorax and in 5 apices of botli 

 scutellum and postscutellum with most of frenum, I'ufescent ; 

 mesonotum glabrous, with a few irregular fine punctures; notauli 

 short and very deeply impressed ; metathorax evenly scabriculous 

 throughout, not basally sulcate ; of S with petiolar carina alone 

 distinct; of $ with areola weak, elongate-oval, longer than 

 broad, apically acuminate, with its carinfe weaker than the 

 centrally emitted costula? ; petiolar area short and not discreted; 



eyes ; face quadrate, longitudinally punctate and laterally sulcate before the elevated 

 orbits; clypeus continuous, smoother, apicall3' broadly rounded with its angles 

 strongly elevated and centre uiinutel.v bidentate ; labrum concealed, cheeks not 

 elongate, lower mandibular tooth slightly the shorter. Antennas setaceous, not very 

 slender, red with the apical third black and central joints subserrate. Thorax 

 cylindrical, dull and closely punctate, brick-red with all the sutures black ; meso- 

 pleur*, dentiparal are^ and the parallel-sided areola all apically produced ; 

 iiietanotum deplauate and double as long as petiolar area ; basal area obsolete, 

 costuliB wanting : spiracles linear. Scutellum and postscutellum red, evenly 

 punctate and subdeplanate, with basal fovea and carinas black. Abdomen parallel- 

 sided and slender, double as long as tborax, obsoletelj' punctate, subnitidulous and 

 black, with venter concolovous and only the second and third segments strongly 

 plicate; basal segment glabious and red, with obsolete punctures and a disca'l 

 longitudinal fovea ; thyridii wanting, valvule exserted. Legs elongate and some- 

 what slender ; deep red with hind tibial and tarsi alone black ; hind femora extending 

 only to apex of second segment. Wings ample and evenly infumate ; radix and 

 tegulaj red, stigma and nervures black ; areolet exactly pentagonal, broad above, 

 emitting the broadly bifenestrate recurrent nervure from its centre ; discoidal cell 

 nearly parallel-sided; nervelet pellucid, lower basal nervure postf ureal ; nervellus 

 intercepted at its lower third. Length, 22 mm. $ only. Type in Mus. Brit. 

 Assam.
