British Braconidx. 7 



behind the eyes, depressed, not wider than the thorax ; occiput deeply 

 excavated ; vertex slightly emarginate posteriorly, traversed by a 

 fine medial furrow ; a deep fovea at the base of the antennse ; face 

 horizontal, carinated in the middle ; clypeus discrete ; mandibles 4- 

 denticulate, the 3rd denticle elongate, acute. Antennse setiform, 

 multiarticulate, shorter than the body in the $ ,very elongate in the ^ . 

 Prothorax deeply sunk between the head and the mesothorax, trans- 

 versely wrinkled ; mesonotum punctate, with inchoate furrows ; an 

 oblong foveola before the scutellum ; furrow of the mesopleurte rugose, 

 metathorax rugose, reticulate, with two irregular longitudinal carinse. 

 Stigma elongate-oval, lanceolate, emitting the radial nervurenear the 

 middle ; radial areolet like that of Dacnusa, semi-oval, attenuated 

 and slightly sinuate before the extremity, which is remote from the 

 tip of the wing. Hind pair of legs robust, elongate. Abdomen 

 twice as long as the head and thorax ; 1st segment in the $ slender, 

 sublinear, finely striolate ; 2nd and following segments strongly 

 compressed, like the blade of an oar ; hypopygium somewhat 

 prominent, shewing the blunt extremity of the terebra ; in the ^ the 

 2nd and following segments are depressed, forming an elongate club. 



Curtis in 1829 published an excellent figure of C. anccps 

 $ , with indications of eleven other British species : he was 

 not aware that the same genus had been described in 1818 

 by Nees v, Esenbeck, under the name Ccelinius. The 

 latter author in his Monograph described two species of 

 Ccelinius, of which the first, parvulus, is a synonym of 

 anceps, but he was not acquainted Avith the $ , and 

 described two ^ s as ^ $ ; the second ^ , from Vienna, 

 belongs to an uncertain species. These defects render it 

 advisable, in spite of priority, to prefer the more 

 characteristic name anceps, and to avoid the absurdity of 

 calling the largest species p)arviilus. Haliday in 1839 

 suppressed Chmnon, and assembled all the cognate species 

 under the name Ccelinius. Forster has utilised both names, 

 attributing to Chmnon the large typical species, and all the 

 others to Ccelinius. Schiodte and Zetterstedt have con- 

 tributed to increase the number of synonyms.
