British BraronidcB. 237 



The unique British specimen answers well to Entlie's 

 descrij^tion, except that the posterior tibite are more 

 broadly black, having less than their basal half testa- 

 ceous. It appears very like tristis, until the 1st abdo- 

 minal segment is examined. Euthe's description was 

 made from a single ? . 



Taken by me on the banks of the Usk, near Aberga- 

 venny. 



12. Microplitis horealis, n. s. 



Niger, jmlpis fuscis, geniculis anticis rufo-testaceis, tarsistibiisque 

 oninibxis fuscis, his suniina basi nifescentibus. Ventris basis, seg- 

 mentoi'um liui 2dique latera testacea. Alse levitei* iufiiscatae, 

 squauiulis nigi'is, nervis stiginate nigi'o-fuscis. Antenna; maris 

 corpore multo longiores, setaceae. Caput cum mesotliorace con- 

 fertissime punctulatuni fere opacum ; scutellum jsaulo Isevius ; 

 mesothorax subtricanaliculatus, suturis liaiid penitus obsoletis. 

 Metathorax fortiter reticulato-rugosus, carinatus. Segmentum 

 Imum duplo lougius quani latius, a basi ad apicem attenuatum, 

 rotuudato-lanceolatum, sicut caetera Isevissimum. Segmentum 

 2dum basi intra marginis flavedinem utrinque oblique impressum. 



Black ; palpi fuscous ; fore knees rufo-testaceous ; all the tarsi 

 and tibiae fuscous, the latter narrowly rufescent at the base. Base 

 of the beUy, and sides of segments 1 — 2, testaceous. Wings slightly 

 infumated, squamulte black, nerAOires and stigma nigro-fuscous. 

 Antencse J much longer than the body, setaceous. Head and 

 mesothorax very thickly punctulate, hardly shining ; scutellum 

 somewhat smoother; mesothorax sho^^ing traces of the three 

 sutures. Metathorax coarsely reticulato-rugose, carinated. Seg- 

 ment 1 twice as long as broad, attenuated from the base to the apex, 

 which is lanceolate and rotmded ; all the segments very smooth. 

 Segment 2 with an obliqiie impression on each side of the base, 

 within the testaceous margins. ^ . Length, 1^; wings, 3j lin. 



The sex is shown by the length and form of the 

 antennae. It agrees in many respects with hu/uhri.^, 

 Euthe, especially the var. with dusky tibiae ; but I doubt 

 its identity with that species, on account of the broad 

 pale margins of the 1st segment, and base of the 2d. 

 If not liignhria, it is at least closely allied. 



Gleuelg, Scotland. The specimen is in Cameron's 

 collection.
