202 Cameron, HymenopUra Orientalia. 



the base closely punctured, their sides keeled. Vertex 

 closely punctured ; the front smooth, hollowed ; down its 

 middle is a stout, sharp keel, obliquely bent on its lower 

 side ; on either side of it at the base is a short, oblique 

 keel ; the upper orbits, close to the eyes, are raised and 

 sharply keeled, as is also the occiput on the lower side, 

 and the latter, shortly above the mandibles, ends in a stout, 

 oblique, somewhat triangular tooth. Mesonotum closely 

 punctured ; the parapsidal furrows narrow but distinct. 

 Scutellum raised, longer than broad, narrowed towards 

 the apex ; closely punctured, thickly covered with fuscous 

 hair ; its sides and apex stoutly carinate ; postscutellum 

 keeled at the sides ; behind it becomes gradually wider 

 from top to bottom, and bears there some stout keels. 

 Median segment smooth in the middle, the sides closely 

 punctured, the outer and apical parts striolated ; the 

 basal area has an oblique slope towards the thorax ; is 

 keeled all round and obliquely narrowed towards the 

 apex ; from it run two keels to the apex, where they 

 slightly converge ; at the top they have a slight 

 rounded, curved slope ; at the base there are two 

 lateral arese, which are wider than their length ; in front 

 of this is an area of about the same size, with the outer 

 side angled in the middle ; the apical area is twice as long 

 as wide. The spiracular area is large, deeply obliquely 

 depressed at the base, wider than long, and separated 

 from the anterior by a stout oblique keel ; all the arese 

 found in the Ichneumonides are clearly defined. The 

 central arese are smooth, the apical thickly covered with 

 short, white hair; the lateral spine is large, leaf-like, 

 transverse. Propleurae closely punctured; the lower side 

 stoutly obliquely striated. Mesopleurae closely punctured, 

 except in the middle behind; above obscurely striated ; on 

 the lower edge is a deep, curved, crenulated furrow;
