Hyvienoptera Orien talis. 115 



RJdnopsis is chiefly distinguished from Ampulex by the 

 wings having only three cubital cellules, the first and second 

 being confluent, and by the body not being metallic green 

 or blue. 



Rhinopsis RUFICORNIS, sp. nov. 



Niger, antennis, ore, thorace, petiolo, tarsisqiie, rufis ; alis 

 hyalinis, fnsco bifasciatis ; nervis sordide testaceis. ? Long. 

 •10 mm. 



Antennae shorter than the thorax ; the basal joint curved, 

 as long as the third, which is two-thirds longer than the 

 fourth. Head coarsely alutaceous, almost punctured ; the 

 front keeled, but not distinctly, the keel being interrupted 

 at the base and apex ; eyes parallel. The keel on the 

 clypeus projects at the apex into a stout sharp tooth, and 

 there is a shorter and blunter tooth on either side of this. 

 Prothorax a little shorter than the head ; the top part raised, 

 narrowed and separated from the lower, and deeply fur- 

 rowed in the centre ; the prosternum and extreme base of 

 pronotum black. Meson otum shorter than the prothorax, 

 parapsidal furrows slightly diverging at the base, and 

 there is an indistinct furrow between them. Meta- longer 

 than the meso-thorax ; the metanotum with a broad, shallow, 

 somewhat oblique, depression on either side ; in the 

 centre (between the depressions) are three keels, the central 

 straight, the lateral converging towards the apex ; but none 

 of them reach the apex of the metanotum. The meta- 

 pleurae are smooth, shining, impunctate ; the rest of the 

 metathorax strongly transversely striolated, running in parts 

 into reticulations. The apex is rounded, margined ; a blunt 

 tooth on either side, and the apex roundly and shallowly 

 incised. The apex is almost perpendicular, broadly fur- 

 rowed in the centre, and covered with a moderately long 

 white pubescence. Pro- and mesonotum coarsely aciculated, 

 sparsely covered with a white pubescence. Petiole smooth, 

 shining, clavate at the apex ; second abdominal segment as
