At least one of the Indian species belongs to Spanotecnus, one 

 of the subgenera into which Forster (Yerh. pr. Eheinl. 1808, 

 ]>. 197) split up this genus ; though it does not altogether coiucide 

 with Thomson's definition of it (Opusc. Ent. ix, p. 911), where he 

 says that tlie hasal metanotal area is elongate, the mesoplenrte 

 closely punctate, with smooth speculum, the abdouien at least 

 centrally pale, notauli wanting, the frenal scrobes strongly dis- 

 crete, epomite distinct though short, and the eyes small. 



The members of rerllissus are known to prey upon sawflies.
