side of the base ; mandibles acutely bidentate ; maxillary palpi 

 elojigate, 3d joint dilated on the inner side, 4th longest ; 2d joint 

 of the labial palpi strongly dilated, obliquely truncated. Antennae 

 setaceous, longer than the body, about 50-jointed. Mesothoracic 

 lobes not gibbous ; sutures distinct. Metathorax short, subtrun- 

 cate posteriorly. Wings ample ; stigma lanceolate ; radial areolet 

 oblong, lanceolate ; radius subsinuated, reaching the apex of the 

 wing ; 1st cubital areolet receiving the recurrent nervure beyond 

 the middle ; 2d smaller, oblong, its lower interior angle produced, 

 acute ; podiscoidal areolet closed. Legs elongate, the hind pair 

 scarcely stouter ; spurs elongate. Abdomen longer than the 

 thorax, subsessile, subclavate, falcate, compressed posteriorly in 

 the 2 , and truncated at the extremity, with 8 segments visible ; 

 1st linear, forming \ of the entire length of the abdomen, widened 

 close to the base, where the tubercles are situated ; the following 

 segments shorter ; 2d not margined laterally ; posterior segments 

 transverse ; anal forceps of the ^ subexserted, compressed, obtuse ; 

 terebra short, compressed, recurved. 



The insects are solitary parasites of Lepidoptera. 

 They are among the largest of European Braconids, 

 and much resemble the Panisci among the Ichneumons, 

 as well as some of the larger Meteori. This is owing to 

 their testaceous colour ; one, however, of our species is 

 almost black. The likeness to Meteorus is enhanced by 

 the similar neuration ; even the radial areolet of the 

 hind wings is similarly coarctate, and in two species 

 divided by an accessory nervure. The structure of the 

 abdomen offers the readiest means of distinction ; in 

 Meteorus there is a real petiole, and the spiracles of the 

 1st segment are removed further from the base ; in Zcle 

 the 1st segment, however slender, is not petiolated but 

 subsessile, and the spiracles are quite close to the base.
