BRITISH ICHNEUMONS. 



'[Nemeritis 



gate nor their tibiae centrally \\hitt> ; two apical hind tarsal joints of 

 siibequal length, witli small unguiculi and claws. Wings with tegulae 

 always whitish ; areolet small and oblique, or wanting ; cubital nervure 

 diyergent from basal ; discoidal cell longer than brachial and its apex 

 subacutely angled below ; neryellus obli(]ue and subgeniculate. 



Known by its very slender form, scabrous second segment, apically 

 produced and evenly declived metathorax, the broad head and wanting 

 or strongly oblique areolet. Our first two species are placed in Forster's 

 typeless genus Phaedrocioniis by Schmiedeknecht, on account of their 

 lacking areolet, though in every other respect they are entirely conform- 

 able with the remainder, and, if needed, Bridgman's female supplies a 

 connecting link in its elongate antennae and somewhat sharply angled 

 radial cell ; to adopt this genus is ridiculous, since specimens frequently 

 occur with areolet in one wing only. Some species bear a strong super- 

 ficial resemblance to the Crcniastides, with which they must not be con- 

 founded.

A black species with the hind legs somewhat broadly infuscate with 

 the trochanterellus pale ; terebra half length of abdomen ; areolet want- 

 ing ; postpetiole smooth, shining and but half length of the petiole ; 

 anterior legs red, basally stramineous. Length, 5-5^111111.

 tibiae, the broad and elongate radial cell and very slender petiole.
