SCOLIONEUBA, Kuw. 



The three species of Scolioneura kuown to me as British are 

 nana, Kl., bcAulcti, Kl., and vicina ,\\\\\v . Nana is easily tlistiiiguislicd 

 hy its white tej^iihc and edj^es of pronotimi, its black and white legs 

 (the hind femora entirely black), and by a dusky bund, which in fresh 

 specimens at least is tolerably distinct, crossing the wings from the 

 stigma downwards. It is also a rather smaller species than the other 

 two. In hetuleti and vicina the tegulse are black, the legs (including 

 the hind femora) are testaceous, and the wings unhanded. These two 

 latter species are certainly very similar, and are probably mixed in 

 most collections, but the wings in vidua are clear hyaline, while they 

 are slightly but distinctly brownish in betuleti. The antenna} also 

 look more slender in vicina. The latter is probably the species 

 described by Stephens as Sidandria fenuicornis, which cannot be the 

 tenuicornis of King, but I am unable to identify it in Mr. Cameron's 

 work, unless it is included in his Bl. hetideti. 



Entodecta, Knw. 

 Of this genus I have one British specimeji from North Wales, 

 which has been determined for me by Herr Konow as ^.i«h2«7j«6', Kl. 

 It is a very small black insect with whitish legs and tegula), and much 

 resembles a Fenusa — having the division between the 1st and 2nd 

 cubital cells practically obliterated as in that genus — but the cubitus 

 itself is quite normal, not bent at a sharp angle as is the case with 

 genuine Fenusa spp. (See my Table of Generic Characters.) Mr. 

 Cameron describes several species under Fenuna which are unknown 

 to me, and perhaps this may be among them. But the synonymy of 

 these small Blennocampids is a subject with which I am not prepared 

 to grapple, and I therefore refrain from offering conjectures which 

 might only make confusion worse confounded. 



MONOPHADNUS, Htg. 



This genus (omitted from my Table of Generic Characters by an 

 oversight for which 1 have already apologized) contains such of the 

 Blennocampids as combine the following characters : («) cheeks very 

 short, {b) 1st cubital n. distinct, (c) two median (recurrent) nn. received 

 in different cells, {d) no separate " prassterna," and (e) hind-wings
