Symmorplius trisalcatui« sp. nov. 



Black, the clypeus, the basal three-fourths of the mandibles, underside of 

 scape, two minute spots over antennae, a small spot behind the eyes, a triangular 

 mark on either side of the base of pronotum, an irregular spot below the tegulae, 

 two spots, wider than long, on apex of scutellum, broad, continuous lines ou the 

 apices of the basal five abdominal segments, that on the 2nd continued on to the 

 whole of the ventral surface, and that on the 3rd and 4th on to the sides only, 

 bright orange yellow ; the apices of the femora, the tibiae and the tarsi of a paler 

 orange yellow, the four anterior tibiae with a broad black line in the middle 

 behind ; wings hyaline, the costa and stigma testaceous, the nervures black. % . 

 Length (total) 9 mm. 



Clypeus as long as wide, almost smooth, the apex with a semi -circular incision ; 

 the front and vertex closely, strongly punctured ; the space between the ocelli 

 aciculated. Base of thorax transverse, keeled, the sides slightly projecting; the 

 apex smooth above, to near the middle, margined by a stout keel. Basal half of 

 mesonotum strongly closely punctured, the middle more coarsely and closely than 

 the sides; the apical half more sparsely punctured ; the parapsidal furrows ex- 

 tend from the base to the apex: they are deep and clearly defined. Scutellum 

 strongly, sparsely punctured, furrowed, but not deeply, down the middle. Post- 

 scutellum prominent, raised above the scutellum, coarsely, rugosely punctured, 

 except at the apex below, where it is sniooth and broadly rounded. Propleurae 

 strongly punctured above, the rest irregularly longitudinally reticulated-striated ; 

 the mesopleurjE irregularly punctured, and with a wide, obliquely rugose furrow 

 below the middle; the metapleurae reticulated above, the rest with fine, close 

 curved striae. The 1st abdominal segment before the transverse keel is smooth, 

 the keel is stout, clearly raised; the apical part is stoutly punctured, depressed 

 in the middle, the depression narrower and more clearly limited at the apex ; the 

 2nd is longer than it is wide at the apex ; it is narrowed and clearly separated 

 from the 1st at the base. Antennae stout, the apex slightly turned down and 

 brown. 



The body is long, narrow, the thorax about three times longer than wide. The 

 apices of the 2nd to 4th abdominal segments are more distinctly punctured than 

 the bases; the apical segments smooth. Seen from the front the head is longer 

 than wide. The basal slope of the long 1st abdominal segment is triangular.

Odynerus Harringtoni sp. nov. 



Black; a broad curved line on the top of the clypeus, a small, transverse oval 

 mark over the antennae, a short, narrow line at the base of the mandibles, a 

 small spot behind the eyes, a line, narrowed in the centre, on the base of the 

 thorax, post-scutellum and lines on the basal five abdominal segments — that on 

 the 1st broadly dilated laterally, and that on the 2ud extended to the outer edge 

 of the segment — luteous, there being also a small luteous conical mark under the 

 tegulae. Wings hyaline, suffused with violaceous, the stigma and nervures black ; 

 the tegulae pale luteous, with a large fuscous central spot. Underside of anteunal 

 scape luteous. 9- Total length 10 mm. 



Clypeus pyriform, as wide as long, closely, strongly punctured, the apex de- 

 pressed, transverse. Base of thorax slightly rounded, the sides of the apex
