L. hicolor, Mg. : I caught this last June tolerably commonly 

 about a hillside pond near Dolgelley. I have also seen it rarely iu 

 Hants and Sutherlandshire. 



L. punctum, Mg. : I hare seen but one British specimen of this, 

 which I caught at Eannoch on June 25th, 1870. 



At 18 in my table I must ask for a correction of a serious mis- 

 print ; the whole second character should not occur here at all, but 

 is in its proper place at 26, those, therefore, who are working from 

 this table will oblige by striking out the last half of 18. 



L. fuscipennis, Mg. ; in this and the next species I cannot follow 

 the recent continental writers : by L. fuscipennis I understand an 

 entirely ochreous species, exactly as Meigen says, " glanzend ziegelroth, 

 welches in der seiten ins Rostgelbe uebergeht." Schiner says, " Riick- 

 enschild obenant glanzend schwarz-braun," therefore he must mean 

 some other species. He says, at the end of his description, that his 

 species is identical with Schummel's and Zetterstedt's L. discoidalis ; 

 I suppose he means L. discicoUis, my next species. I am convinced 

 my next species is Zetterstedt's L. discicoUis, but I am uncertain 

 about its being Schiner's X. yMsct)?ewms, because he says L. fuscipennis 

 has the basal joint of the antennae yellowy while in what he calls L. 

 discicoUis that joint is grey or blackish. Westhoff gives a good cha- 

 racter for separating some of these species, but unfortunately I do 

 not know which is the " upper " and which the " lower " third of the 

 discal cell, I could understand "basal" and "apical," or "inner" and 

 "outer," but the "upper" and "lower" thirds of an oblong are 

 beyond me. My " glanzend ziegelroth " species has occurred in some 

 abundance in a very small spot near Frant, also in Hampshire in two 

 or three localities. 



i. discicoUis, Mg. : by this 1 mean a species with the peculiar 

 venation given by Meigen (as in my table), and a shining dark brown 

 disc of thorax with testaceous pleurae. It is very common, and my 

 most divei'gent localities are Slapton, Inchnadamph, Diss and Dolgelley. 



L. suhtincta, Ztt. : since my list was published Mr. Jenner has 

 taken this species near Lewes from May 23rd to June 1st. It is most 

 allied to i. discicoUis smd. fuscipennis, having almost their venation ; 

 a handy character in tliese three species is that tlie base of the second 

 sub-marginal ceU is at a right angle tvith the prcefurca ; L. suhtincta, 

 however, differs a little, as the praefurca itself in my three specimens 

 also starts at a right angle with the sub-costal vein, and has a recurrent
