Of the grey or black species, E. fuscipennis, Mg., is the smaller 

 and blacker, and has the veins hairy all their length, while E. trivialis, 

 Mg., has them hairy only on their ends. E. trivialis is very near the 

 genus Symplecta but for these hairy ends to the veins, and I have seen 

 it sometimes have a dark cloud crossing from near the end of the sub- 

 costal vein to the upper branch of the radial, resembling the super- 

 numerary cross vein of S. punctipennis, Mg., only placed between 

 different veins. Both species are common, and I have seen E.fusci- 

 pennis from Penzance to Tongue (I could not go much further), and 

 E. trivialis from Lewes to luchnadamph. 



Lipsothrix errans, Wlk. : I have no doubt about the synonymy of 

 this species, and, in accordance with Loew's doubt (Bes., Eur. Dipt., 

 iii, 69), I can remark, that out of eleven specimens only one male hag 

 quite black knees ; this specimen seems rather small, and with legs 

 rather short and thin, but I do not think it distinct : others have the 

 knees a little darkened. The species is at first glance so remarkably 

 like the large yellow Eriopterce or Dicranomyiae, that I have no doubt 

 it is often overlooked, but its very distinct neuration at once identifies 

 it. I have taken it at Lyndhurst, Eotherfield and Wadhurst in Sussex, 

 and Inveran in Sutherland.

Note on the genus Eudectus. — Through the kindness of Horr Weise I have 

 recently received an example of Eudectus Girdudi, Redt., and as I have just now 

 before me the only example of Eudectus rufulus, Weise, found by Mr. Lewis in 

 Japan, I have taken the opportunity to compare these examples with the unique 

 specimen of our British E. Whitei. As the result of this comparison, I think all 

 three should at present stand in the Catalogue of Coleoptera as distinct species. 

 The differences in colour between the three are very marked ; but as E. Giraudi is 

 known to be variable in this respect, they may be considered to be of minor im- 

 portance, and would be insufficient to substantiate the species if there were no other 

 differences. Other differences are, however, numerous. E. Giraudi is larger than 

 either of the other two insects, and is specially remarkable by the great development 

 of the angular sides of the thorax, and the thi-ee conspicuous depressions on the 

 disc of this part. In E. Whitei the thorax is much narrower, the angulation of the 

 sides only slight, and the three discoidal impressions are obsolete. In E. rufulus 

 the angulation of the sides can scarcely be seen, and the discoidal impressions are 

 absent. E. Giraudi has the vertex of the head more densely punctured than it is in 

 the Japanese and Scotch insects. 



If these distinctions prove constant, the three insects are readily enough dis- 

 tinguished ; but it is probable that other localities will yield specimens connecting 

 them. At present they are all extremely rare, and are each resti'icted to widely
