Obs.—Dr. Hagen states that Mr. Walker has described a spe- 
cies of the Trichoscelian group of Mantispa under the name of 
Raphidia! varia. ‘The description, however, of that insect as 
given in the British Museum Catalogue of Neuropterous insects, 
part il. p. 212, cannot possibly be intended for the insect before 
me, being “ Nigra, antennz robustz basi ferrugineze; prothorax 
linearis; pedes rufescentes. Black, head hardly longer than 
broad. Appears to connect Raphidia with the Hemerobii.” If, 
contrary to reasonable expectation, it should prove that the insect 
above described is identical with that described by Mr. Walker, 
[ maintain that his description is so erroneous that it is virtually 
worthless, and that no Entomologist is bound to adopt the spe- 
cific name prefixed to it.
