Viridana is, I believe, distinct from any recorded British species. 

 I took a ? at Lyndhurst, Hants, on May 28th, 1902, which was 

 determined for me by Herr Konow. 



Quercus differs from all other species in the distinctly red-banded 

 abdomen, which is a very unusual type of coloration among the 

 Nematids. I have only once taken it ; near Sunningdale on June (jth, 

 1903. 



Suhhifida. — I have followed Konow in distinguishing this species 

 from hetidcB by the yellow mesopleurae and Thomson in the original 

 description gives this character, I have, however, certain British 

 specimens with hlach mesopleurae, which seem too small for hetults, 

 and in general appearance and form of claws quite agree with typical 

 suhhifida. It is possible that these. are a distinct species, but I think 

 it best at present to treat them as an aberration of suhhifida. 



Sefulcd. — ^ojww gives hrevicornis, C, as a synomym of this 

 species. This refers, I presume, to the insect described in Mon., 

 vol. ii, p. 80, as parvicornis = hrevicornis, Thoms. Mr. Cameron, 

 however, gives his species in vol. iv as a LygcBonematus. 



Ohlongus, C — According to Konow the ? of this is Lygceonematus 

 laricis, but the ^ (probably) hiscalis. 



LYGiEONEMATUS, Knw. 



The genus Lygcdonematus, Knw., brings us to the end of the 

 Nematides. It consists almost entirely of small or medium-sized, 

 sombre-looking insects, often entirely without bright colouring, and 

 with hardly an exception black above or practically so. Mr. Cameron 

 in vol. iv enumerates thirteen British species, whereas I can only 

 muster nine, of which six only appear to be described in the 

 Monograph. But of Mr. Cameron's species a good many are sunk 

 by Konow as synonyms, and one, at least, referred to a different 

 genus. Thus, according to Konow, 



erichsoni (Htg.), C, is a Holcocneme. 



leucopodius and pladdus (C.) = leucopodius, Htg. 



anibiguus, fraternus, and furvescens (C.) = amhiguus, Fall. 



lativentris ? and scoticus (C.) = biscalis, Forst. 



mollis, hreadalhanensis, whitei, and astntus (C.) = mollis, Htg. 



The three species in my list which do not seem to occur in the 

 Monograph are pini, of which I have a ^ taken by Dr. Capron ; 

 saxeseni, of which a pair now lie before me taken by Mr. Atmore at 

 King's Lynn, and communicated to me by Mr. T. E. Malloch, of
