$ . An elongate, slender black species, with the greater part 

 of the legs and abdomen red. Head with frontal orbits, palpi, 

 mandibles, and the closely punctate face and clypeus, flavous ; 

 epistoina above, and the mandibular teeth, black ; vertex super- 

 ficially and sparsely punctate, frons more shining and transversely 

 aciculate. Antenna black, with the 

 scape, except centrally above, fla- 

 vous. Thorax immaculate, closely 

 and strongly punctate ; metanotum 

 with two central areac, the basal 

 being the shorter ; its base trans- 

 verse in the middle, becoming 

 obliquely wider, then gradually 

 narrowed, the keels bounding the 

 narrowed part being slightly 

 curved, not straight like the 

 basal ; its apical hall: transversely 

 striated ; the apical area more 

 strongly transversely striated ; 

 the basal outer area closely and 

 finely punctate ; the apical trans- 

 versely rugose ; the spiracular area 

 distinctly defined, of equal width 

 throughout, and closely trans- 

 versely rugose ; its apex rounded 

 and ending opposite the base of the 

 middle coxae ; behind it is a narrow 

 area, reaching to the hinder coxa3 ; inside, this area is coarsely 

 rugose (sec Cam.) ; pleurae strongly punctate, mesopleurse cen- 

 trally strigose and basally smooth. Scutellum not, or hardly more 

 strongly punctate than the mesonotum, with its sides and apex 

 strongly and distinctly striate ; postscutellum cariniform. Abdo- 

 men red, with the first segment entirely, the second discally, and 

 the third basally, black ; first segment basally glabrous and beyond 

 the centre isolatedly punctate, finely and closely aciculate laterally 

 above before its apex ; second closely and finely aciculate longi- 

 tudinally throughout to near its smooth apex, and, like the third, 

 which is only basally aciculate, discally impressed ; terebra two- 

 thirds the length of the body. Legs red, with the anterior coxa& 

 and trochanters flavous. Wings hyaline and extending hardly 

 beyond the apex of the second segment ; nervures and stigma 

 black ; basal and apical abscissae of the radius oblique, the Litter 

 larger and somewhat less straight ; second recurrent nervure 

 broadly fenestrate above. 

 Length 15 millim.
