ten in number; tlie suiTaco of tlio truncation coarsoly ni^roso. 

 Alnlomen sliort, the two basal soi^nionts sliininj:^ and tinoly 

 jHincturoc], tlio third se;j[inent dtdicafely vcficul.ite and j)nl)os- 

 ccnt, the apical sei^nients small and witlidrawii. 



Black ; the antenna?, mandibles, tibia*, and tarsi fiisco- 

 ferrufjinous ; abdomen shininp^ golden bronze. Wings 

 Jiyaline, iridescent, with faint fuscous clouds near the centre 

 and in the second cubital c{dl. The first transverse cubital 

 nervure is sharply l)ent outwards near the base and thro^vs 

 out a shoit branch inwards, so that the first cubital cell is 

 imperfectly divided. 



Length 6 mm. 



flab. Victoria. 



Genus AucriENOPiiORUS, nov. 



? . Head as broad or broader than tlie thorax ; the cheeks 

 well developed ; the eyes reaching to the base of the man- 

 dibles, convergent towards the vertex. Antennfe with the 

 ajiical joints somewhat stouter than the basal, shorter than 

 the he;id and thorax, not covered at the base by a tubercle. 

 l^Iandibles acute at the apex, not bidentate ; the apical outer 

 angle of the maxilla produced into a prominent lobe, the 

 maxillary palpi five-jointed, the joints in the tyj)ical species 

 rather short and subequal ; labial palpi four-jointed j labrum 

 transverse, straight, strongly ciliate on the anterior margin. 

 Pronotum narrower than the mesonotum, depressed anteriorly; 

 mesonotum short, the posterior margin not reaching beyond 

 the ])Osterior margin of the teguhe. Median segment rather 

 long, flat above, truncate jiosteriorly, marked dorsally with a 

 straight median carina from the base, continued on the 

 surface of the truncation to the apex, also with a carina on 

 each side converging from the base and forming a triangle. 

 Abdomen pseudosessile or subpetiolate, the apical segments 

 not very short, none of the segments constricted at the base. 

 'Jhe trochanters long, the intermediate and posterior tibiae 

 slightly spinose, the intermediate tibiai with only one apical 

 spine ; the joints of the tarsi slender and elongate. Wings 

 sliorf, with only one cubital and one discoidal cell, the radial 

 cell short, subtruncate at the apex; the cubital cell large, 

 receiving the recurrent nervure at about two thirds of the 

 distance from the base to the apex. The anal cell of the 

 hind wing is short ; the apex of the median cell touches the 

 costa; the radial and cubital nervures are only faintly 

 indicated beyond the median cell.
