ICHNEUMONID.E.— HOPLISMENUS, 275 



Genus L.— HOPLISMENUS, Gravenhorst 



Aniennw rather slender^ of the male porrect^ of the female curved, a little com- 

 pressed and dilated towards the apex, and consisting of about 40 joints : 

 head short, rather narrower than the thorax, and straightened towards the 

 neck: ey^s o\3l: thorax gWihons, generally armed with an acute spine on 

 each side of the metathorax : icutellum 4-angular, or somewhat 3-angular : 

 abdomen petiolated, convex, oblong, the apex acute, the basal segment with 

 '2 elevated longitudinal lines, continued on the peduncle, which is linear and 

 rather long : ovipositor a little exserted, short : legs rather slender. 

 Hoplismenus, as the name implies, embraces several species which 

 have the metathorax armed with 2 rather elongate acute spines, or 

 tubercles; the abdomen is also oblong, the basal segment has 2 

 elevated lines, the ovipositor is exserted, but short ; the cellule is 

 5-angular ; the legs and antennae rather slender, the latter, in the 

 females, somewhat compressed and dilated towards the apex : the 

 species appear to be rare in Britain.
