Observ. Sculptura et pictura maxime affinis duabus proxime praecedentibus (Chr. Gyllenhali et Chr. sociae); at certe distinguitur corpore majori et robustiori, punctura thorarica crassiori, abdominis segmento 3:tio infra discum obsoletissime immerso et tum mox ante seriem apicalem lenissime calloso. Etiam Chrysidi coerulipedi valde similis, sed capite coeruleo et postscutello mutico convexo certe dignoscitur. Caput mediocre rotundato-triangolare, pronoto paullulum latius, confertim modice punctatum subrugulosum coeruleum aut cyaneum parum nitidum subopacum, orbita viridi. Vertex convexo-depressus. Cavitas facialis mediocris subtilissime sparse punctulata, canalicula mediana subtili abrupta. Antennae breves robustae nigro -fuscae cano et fusco-puberulae, scapo infra cyaneo, sequentibus duobus articulis supra virescentibus. Clypeus mediocris cyanco-viridis punctulatus, medio carinato-convexus, utrinque concavus, margine apicali polito piceo-troncato. Mandibulae mediocres basi virides, tum piceae et ante apicem rufescentes. Pronotum et mesonotum coriaceo-rugulosa crasse punctata virescenti-aurea; pronoti sulcus medianus propter rugositatem irregularis, truncatura antica concaviuscula subcrasse punctata viridi-aenea: areola centrali polita utroque sulco arcuato; dorsuli suturae 2 medianae subprofundae subrectae crenulatae basi parumper curvae. Postscutellum convexo-obtusum modice punctato-reticulatum. Metanoti anguli postico-laterales mediocres triangulares. Metanotum cyaneum, ad latera nonnihil virescens. Pleurae rugosae punctatae sub-opacae, sternum nitidum subtiliter punctulatum viridi-cyanea aut cyaneo-viridia, pedes concolores tarsis fuscis. Alae hyalinae, interdum disco sordidae, tegulis l. viridi-aeneis l. viridi-cyaneis, venis piceis, cellula radiali completa triangulariter lanceolata: angulo disci recto, in cellula radiali vitta brunneo-fumosa. Abdomen capite thoraceque simul sumtis longius, latitudine thoracis, ovali-ellipticum, dorso convexum purpureo-, coccineo- aut virescenti-aureum, confertissime punctulatum 1. coriaceo-subopacum 1. nitidum, in disco segmentorum 2:di et 3:tii lineola mediana sublilis elevata animadvertitur; segmentum 3:tium disco (1. paullulum inferius) obsolete aut obsoletissime (scil. varie in variis individuis) transverse subarcuato-immersum, tum (secundum immersitatem) lenissime callosum 1. convexo-subelevatum, series ante-apicalis infra hanc lenissimam convexitatem sita regularis aut irregularis scil. foveolis parvis ovalibus numerosis distinctis aut confluentibus constituta; margo apicalis fortiter convexo-arcuatus, angustior quam margo basalis, convexo-depressus subtiliter punctulatus, summus brunneus; segmenta ventralia basi nigra, apice ignea marginibus summis apicalibus piceo-scariosis, segmentum anale piceum.
