AssiiiuHs is one oE our prettifst and most common Blennocampid 

 species. I have an impression, which I regret that I have not time 

 to verify before this paper goes to press, that Konow now calls it by 

 another name (P nffinis. Fall.), but it is still called assimilis in his 

 Catalogue of 1S90, and I may be labouring under some misconception 

 on the subject. 



Geniculata, Steph., is not to be confounded with the geniculata of 

 Mr. Cameron's Monograph, to which we shall come later in discussing 

 Monopliadnus. 



Thomson and Cameron separate from suhcana a form which they 

 call subserrata, but Konow appears not to admit it as a distinct 

 species, and I am not acquainted with it myself, even as a variety, so 

 I cannot introduce it into my Table. (According to Mr. Cameron it 

 differs from subcana in having the tegulye and edge of pronotum 

 white, and from alcJiemillce [= tenuicornis] in the structure of its 

 antennje). 



Konow formerly included in his Bhnnocampa, for which he has 

 now formed a new genus, Scolioneura, in consequence of a difference 

 in the neuration of their fore-wings, the discoidal n. and 1st medial n. 

 being not sub-parallel, but convergent. The genus has three British 

 representatives ; but I must defer consideration of them to another 

 paper, in which I hope to deal with the remaining genera of the 

 Blennocavipides.
