British Braconidx. 2S 



A supposed parasite of Siplionophora granaria, Kirby, 

 a puceron infesting several species of grass. Yet the 

 identification seems doubtful, judging by Buckton's figure, 

 (Aphides, vol. i, pi. vii,) which represents an insect very 

 different from an Ephedrus. However that may be, Mr. 

 Buckton's observation is conclusive with regard to the 

 minute hyperparasite Lygocerus carpentcri, Curtis, which 

 he viewed under the microscope, enclosed with some 

 Siphono2')hora}. This was a ^ , who was observed to de- 

 posit several eggs in the bodies of those Siplionophorx 

 previously occupied by Aphidian parasites. It is therefore 

 no longer to be doubted that the species of Lygocerus, and 

 probably many others, if not all, of the Gercvphron group in 

 the Proctotrypidse, are hyperparasites. E.2ilagiator,ih.o\x^ 

 not very common, is widely spread, having been noticed in 

 Germany, Italy, Belgium, Holland, and Spain, whence I 

 have received specimens from Seville. 



III. TOXARES, Haliday. 



Trionyx* Hal., Eat. Mag., i, 487 (1833) ; Toxares, Hal, 

 in Westw,, Int. ii, Synopsis, 65 (1840). 



Head transverse, rounded. Palpi rather long, the maxillary 4-, 

 the labial 3-jointed ; mandibles acute, deeply bidenticulate . 

 Antennae somewhat elongate, 19-22-jointed. Thorax glabrous ; 

 mesothoracic furrows hardly visible, converging as usual. Neuration 

 in general similar to that oi Ephedrus ; praediscoidal areolet complete ; 

 3 cubital areolets ; stigma narrow, elongate, lanceolate at both ends ; 

 radial areolet cultriform, reaching the tip of the wing ; anal nervure 

 not interstitial ; intercubital nervures sometimes indistinct. 

 Abdomen of the 9 spathulate, or claviform and flattened, sub- 

 petiolate ; that of the ^ narrower, oblong ; 1st segment linear, the 

 tubercles situated before the middle ; segments 2-3 the longest, the 

 rest short, transverse. Terebra curved downwards, its valves much 

 dilated underneath, of deltoid foim, trifid at the extremity. 



This genus resembles Praon in the palpi, and Ephedrus 

 in the wings ; in other respects it comes nearer to 

 Monodonus, the antennae, the 1st segment, the abdomen of 

 the $ , and the general facies, being much the same ; 

 only the Monodoni have their labial palpi 2-jointed, ac- 

 cording to Haliday. In order not to mistake a Toxares, on 



* Trio7iyx was rejected on account of its preoccupation as a genus 

 of Chelonian Reptilia.
