2 . Closely allied to H. propinquus (p. 430) : differs in being 

 larger and more stoutly built, with comparatively a larger head ; 

 the median segment is proportionally smaller than in H. propinquus 

 and has the apex more truncate, the enclosed space at the base is 

 narrower and much more finely punctured, the punctures running 

 into oblique striae. Like H. propinqmis it is of a bronze-green 

 colour, with white pubescent transverse fasciae on the apical mar- 

 gins of segments 1-5, the apical segment \\ith thick fulvous-white 

 pubescence on each side of the anal rima ; wings hyaline, saturated 

 with yellowish towards the base, nervures and tegulae testaceous.
