when denunded of tomentum; beneath, it is conspicuously flattened 

 or subdepressed behind the middle, raher strongly punctate and the 

 surface between these punctures is shining and finely, but conspicu- 

 ously punctulate. Length to apex of second abdominal segment 8-9 

 mm. Described from males only. 



Ilab. Australia ; common, in middle Queensland. 



Ischnocoelioi gen. nov. 



Head in front view subrotundate, mandibles shortish (not at all 

 like those of Eumen.es) with four terminal well developed teeth; 

 clypeus widely truncate or slightly rounded at apex; maxillae with 

 very elongate galea, attenuate to the tip, the maxillary palpi very 

 short, three-jointed, the three joints together hardly as long as the 

 second joint of the three-jointed labial palpi, of which the two basal 

 joints are subequal and elongate, the third hardly half as long as 

 either of these; ligula long and slender, deeply cleft at the apex, the 

 bifurcations pilose, as also a portion of the ligula behind these, the 

 intermediate space bare. Wings with the second cubital cell narrowed 

 to an angle above, the sides meeting at the radius, the second recur- 

 rent nervure received nearly at the middle of tbis cell on the cubitus, 

 the first recurrent between this point and the lower basal angle of the 

 cell, but nearer the latter. Middle tibiae with two well-developed cal- 

 caria, the tarsal claws toothed beneath near the middle. Abdomen 

 pedicellate, the first segment sublinear throughout, ai)out four times 

 as long as its greatest width, widening slightly, but not adruptly, at 

 about its basal third, and continuing of nearly equal width on its 

 apical half; second segment campanulate with a very short neck at 

 base. Female. 



From the foregoing characters it is clear that this insect in some 

 respects is intermediate between the subfamilies Ischyioga^terinae and 

 Discoelirme as defined by Ashmead, but I consider these groups at the 

 most as of tribal value. 



IscJinocoelia xantliochrowM, sp. nov. 



Black with orange and reddish markings, the red and yellow colors 

 more or less shading into one another, so that except in certain parts 

 they may be generally designated as orange. Head black, the antennae 

 ferruginous, but black or dark above on the apical half of the flagellum; 

 the clypeus, a more or less triangular spot above this, emarginate 

 posteriorly, the sinus of the eyes, the sides of the head behind these, 

 as well as the vertex posteriorly except in the middle, orange. Pro- 

 notum, tegulae, scutellum, propodeum (excepting the sides and some- 

 times the base medially) and a large area on the mesopleura orange; 

 legs yellow, the hind pair more ferruginous, their coxae mostly black, 

 the middle ones nearly Avholly reddish, but variable in color. Wings 

 hyaline, yellow along the costa, as also the stigma. Neuration general- 

 ly dark, but the veins yellow or brownish towards the base of the 

 wings, as also the co'^ta to the stigma. 



Head incras«ate, densely and somewhat coarsely subrugo<^ely punct- 

 ured; mesonotum somewhat shining, punctured like the head or 

 slightly more coarsely, and with dense minute punctures between the
