HEDYCHRUM. 429 



gular, slightly convex, rugose, the apex beneath subacute ; post- 

 scutellum large, prominent, strongly convex, overlying the median 

 segment, the posterior lateral angles of which are broadly produced 

 with their apices acute ; wings hyaline, a broad fuscous border on 

 the fore wing from the base of the radial cell round the outer 

 'margin of the disc ; nervures and tegulae brown. Abdomen 

 very broad and short, strongly convex, the base truncate and 

 slightly ernarginate, the apex steeply sloped, the apical margin 

 broadly rounded, with a minute but' very distinct tooth on each 

 side. 



<$. Identical in colour, smaller, with the sculpture on the 

 abdomen slightly coarser. 



Length, $ 6, <J 5'5 ; exp. $ <$ 12 mm. 



Hob. Bengal (apud Dahlbom)- Punjab, Lahore, Delhi (Binq- 

 .ham) ; Northern G-ujerat ; Quetta (Ifurse). I found this species at 

 Delhi around the burrows of a Bembex which I failed to capture.

$ . Metallic green, the space round the ocelli, two broad 

 anteriorly convergent bands on the middle of the pronotum, the 

 sides and anterior portion of the medial area on the mesonotum, 

 the middle of the 1st, and the bases, broadly, of the 2nd and 3rd 

 abdominal segments purplish blue, in some specimens the blue is 

 more spread, in others less ; antennae and tarsi black, scape green 

 in front ; head and thorax densely punctured, rugose, the facial 

 hollow finely transversely striate, the punctures on the middle of 

 the mesonotum posteriorly, and on the scutellum, postscutellum 

 and median segment large and cribrate ; abdomen finely and 

 densely punctured, the punctures shallow; pilosity brownish, 

 fairly abundant. Head subtriangular, broad and slightly convex 

 posteriorly ; clypeus moderately broad, subporrect ; antenna) 

 cylindrical, 2nd joint of the flagellum the longest ; facial hollow 

 deep, with no transverse carina above it, ocelli placed far back on 

 the vertex. Thorax : pro- and mesonotum subequal, convex, 

 transversely rectangular, the sides of the pronotum slightly 

 convergent anteriorly ; the scutellum, postscutellum and median 

 segment roundly convex, the posterior lateral angles of the last 

 produced and acute ; wings hyaline to fusco-hyaline ; legs short, 

 somewhat slender. Abdomen strongly convex, the base transverse 

 with a slight medial impression ; the apical margin of the 3rd 

 segment rounded, laterally obscurely angular, subdentate; the 

 preapical series of foveae moderately well marked, in some 

 specimens distinct, entirely absent in others. 



d 1 . Similar, smaller and a little narrower. 



Length, $ 6, exp. 12; 5'3, exp. 12 mm. 



Hob. The Indo-Malayan region. 



I found this species parasitic on Odynenis bipustulatits, Saussure, 

 but only males were bred out of some nests 1 had of that wasp.
