between CcsciJiiis and Sfenopsociis. With tlae former of these it 

 agrees in its open discoidal cell, and the arrangement of the jiosterior 

 marginal cellules, but differs in the abbreviated transverse vein from 

 the lower angle of the pterostigma 

 (indicated by a in the figure) end- 

 ing abruptly in the membrane 

 about half-way towards the forked 

 vein beneath it, thus indicating 

 some affinity with Sfenopsocus, in 

 which this sub - pterostigmatical 



vein is continuous ; but the latter genus has a closed discoidal cell. 

 The tarsi are 2-joiuted. 



Psocus palliafits, Hagen, which is at present unknown to me, has 

 a similar abbreviated sub-pterostigmatical vein, but a closed discoidal 

 cell. It probably forms the type of another genus. 



Amphipsocus pilosus, n. sp.

 dihitatce- ac fere semicirculares ; venis longe pilosis, plerumque Jlavidis, 

 nonnuJlis nigris, apicem versus paullo Jlexuosis ; celluld libera marginali 

 triangnlari; pterostigmate elongato-triangidare, rosaceo-suffuso, puncto

Exp. alar. 4^ lin. (=9 will.). 



Hab. : — Northern India. In Mus. auct. 



I have five examples of this pretty species, three of which were 

 taken by Capt. A. M. Lang at Masuri, in the month of June. 



Note 3 : — A type specimen of Psocus cJiloroficus, Hag., shown to me 

 by Baron de Selys Longchamps, has a decidedly different 

 neuration to that of Psocus (as restricted), there being a 

 closed discoidal cell, but only three marginal cellules instead 

 of four : it will form a new genus. ( ^ e.wv' ? S^ C M 9 S-<AJ.^ 



Note 4 : — The type of the insect described by Rambur as Psocus 

 pedicularius is very curious, and has nothing whatever to do 

 with the Linnean species of that name {binotatus, Eambur).
