British Braconidce. 277 



3d. Second cubital areolet sessile, quadrangular. Terebra as long 

 as the abdomen. J . Length, 2;^ lin. The British specimen is 

 only ItV lin. long ; wings, 3 lin. 



Distinguished by the shortness of the terebra and of 

 the 2d segment. In the British specimen the femora 

 are narrowly infuscated at the base ; the intermediate 

 tibias, as well as the hind pair, are infuscated at the tips, 

 and faintly annulated below the base with the same 

 colour. 



One 2 taken at Maldon by Fitch, August 11th.

Hal., Ent. Mag., i., 262; iii., 113; Reinh., Berl. ent. 

 Zeit., 1865, p. 260. 



Maxillary palpi 6-, labial 4-jointed. Face not produced or rostri- 

 form. Mesothorax trilobate. Mesoplem-te with a crenulate furrow. 

 Two cubital areolets, the 1st distinct from the priediscoidal. 



Form narrow, linear. Head scarcely as wide as the thorax ; 

 occiput distinctly margined ; face with 2 deep fove® above the 

 clj-peus. Wings short, narrow; stigma lanceolate, not bulging 

 beyond the costa ; radial areolet narrow, cuneiform, yet broader 

 than in the preceding three genera, ending much before the apex 

 of the wing ; radial originating beyond the middle of the stigma ; 

 1st intercubital nervure obhque, almost in a line with the 3d 

 abscissa of the radius. Hind cox£e, spurs of the hind tibi«, and 

 terebra, elongate ; the coxae also incrassated. 



In the ' Magazin der Gesellschaft naturf. Freunde zu 

 Berlin,' Nees v. Esenbeck, in 1814, described four species 

 of this genus, forming Section II. of his Microdus, viz., 

 M. inmctidator, Uechjator, ohscumtor, and annidator. 

 These he repeated in his Monograph in 1834, with the 

 addition of another species, rugosus, which he incon- 

 sistently placed under Microgaster. Haliday, in 1833, 

 established the genus Orgdus for Microdus Sect. II. of 

 Nees, and in 1835 described the British species ohscurator, 

 regarding Uevigator and annidator as synonyms. He 

 placed Orgilus, on account of the number of joints in the 

 palpi, in the same group as Zele and Macrocentrus ; an 

 arrangement which is supported by the general resem- 

 blance of those genera. The affinity of Orgdus, how- 

 ever, to the Agathis-Microdiis-gioui:) is much more 

 striking, and those who regard the palpi of Hymenoptera 

 as affording characters of only secondary value, will
